Technics Reborn (and the Direct Drive elephant in the room)

Technics was one of the great audio mainstays. It was founded (as a part of the great Matshushita conglomerate) in 1935 as a music-technology brand. It made pianos, and stereos, and DJ equipment, and had a commanding reputation for high quality and value both in and outside of its native Japan. In the 21st Century, Matsushita made a global corporate decision to fold all its subsidiary brands (including National and Technics) into the one name; Panasonic.

At the time, there was good reason for this. This was the time of ‘convergence’ (as a concept, rather than a practical reality), and the idea was a Panasonic customer would listen to music controlled by their Panasonic TV set through Panasonic audio electronics, all the while downloading images from their Panasonic camera, and presumably cooking their meal on their Panasonic microwave oven. Nice idea, but it didn’t happen that way, and Matsushita has recognised that by reintroducing subsidiary brands like Technics.

Fast forward six years since the last Technics-branded product and the name is back. The company has recognised the music world has changed, and not totally for the better, so Technics is going gung-ho into the world of high-resolution audio. Its core products today are formed into two systems, both comprising networked source, amplifier, and loudspeakers. In the top end Reference R1 system, it comprises a €6,999 SU-R1 networked preamplifier, with a €12,999 SE-R1 power amplifier, and €19,999 SB-R1 floorstanding loudspeakers. In the more mainstream Premium C700 system, the network pre becomes a €899 SU-C700 networked player, while the SU-C700 integrated amplifier and SB-C700 standmount loudspeakers also appear to cost roughly one-tenth the price of the Reference equipment. Technics has also joined forces with 7 Music (one of the bigger digital content providers in Europe) to roll out ‘Technics Tracks’, a growing collection of FLAC-based downloads in at least 16-bit, 44.1kHz CD grade quality, and up to 24bit, 192kHz high resolution formats.

 

Technics people are keen to point out they missed music’s bump in the road, when sound quality took a dip in the first years of the 21st Century, with the world moving from Napster to iPod to iPhone. Technics wasn’t asleep at the switch during this time – the brand simply didn’t exist. Now that people are beginning to view music quality as important again, the sleeping giant awakes!

I can’t speak of the performance of the two high-resolution systems (demonstrated this week at London’s Audio Lounge), because I’m currently nursing the kind of head-cold that renders any music a little like Charlie Brown’s teacher. What I could hear through blocked sinus cavities sounded pretty good, but I’d have struggled to tell high-resolution from the sound of a broken telephone, so any critical assessment will have to wait. However, I think there’s some good (and some not so good) to be drawn from this launch. From a technical perspective, I’m not convinced that a large 150W per channel chassis with huge VU meters is needed for what is basically a Class D amplifier design, although Technics insist the technology is more complex than a quick scan of the specifications suggests. On the other hand, from a technical perspective, the point source concentric drive units that form the acoustic centre of the loudspeakers is really interesting, and it’s clear this Technics relaunch is something more than just a technological rehash.

The move toward high-resolution by another one of consumer electronics’ ‘big boys’ (following Sony’s recent entry into high-resolution audio) potentially adds further legitimacy to the ‘there’s more to music than iTunes’ cause, and the company linking itself so early in the story with 7 Music is a sign Technics means business here. But I can’t help feel this lacks the ‘hook’ required to grab the attention of a more mainstream buyer today. The entry level Technics system comes in at around €3,000, which puts it somewhere between mainstream music lover (who now buys Sonos, and largely isn’t that bothered about high-resolution) and the audiophile buyer (who already has their own position on high-resolution, even if that relies on abandoning digital for LPs).

This concept might also fall between the cracks of today’s potential market. Increasingly, we’re seeing moves toward high-resolution streaming solutions, such as TIDAL and Qobuz. People have become extremely comfortable with subscription services such as Spotify, often moving away from providers like iTunes as a result (one of the many conspiracy theories surrounding iTunes purchase of Beats is that the company came with Beats Music, and with that MOG, thereby creating a ready-to-roll subscription service). The Technics system can support streaming solutions, but through its asynchronous USB ports, like most USB-ready DACs. Instead, this is a networked system, designed to run from a NAS full of music. However, this seems to be driven by remote handset and there was no discussion of app support during the press conference.

Back to that ‘hook’. Technics as a brand has one significant ‘hook’ in its back catalogue; the SL-1200 and subsequent direct drive turntables in that series. Although the SL-1210 turntable has been discontinued for four years, it manages to retain a loyal following. That’s some considerable understatement; the online following for this turntable is so profoundly loyal to the ‘Techie’, many will brook no criticism of the design. In fact, so powerful is this group that the word ‘Technics’ is virtually synonymous with the SL-1210. And Technics simply cannot make them anymore, because of tooling costs and unavailable parts. I suspect Technics may find itself trying to explain that it now makes digital audio, in perhaps the same way the Hoover Corporation tries to explain that it also makes washing machines and steam irons.

Like high-resolution audio in general, I want this to succeed. I want Technics (and Sony) to return to the audio world with a greater presence, because I want more people to experience the joys of good audio and I can’t shout that loud enough without climbing on the shoulders of giants. I want these products to incite music lovers to derive more pleasure from their music and demand more from their music producers. I want that 45% of music buyers who recognise that their MP3 tracks might be imperfect, and the 70% who think this might be an ‘issue’ (according to Technics) to start discovering the joys of good quality sound.

It’s just that is this too much, too late?

Eclipse TD TD725swMk2

This magazine has covered a lot of subwoofers in its time, because in most rooms the best speaker location for bass reproduction is not the same as the best placement for proper mids and highs. This hold true whether we are discussing driver placement relative to internal cabinet vibrations or speaker placement relative to low-frequency room modes. Of course, there are some loudspeakers that require more bass reinforcement than others, and arguably the Eclipse TD loudspeakers are among the most obvious candidates.

But with great power comes great responsibility, and the task of bolstering up the bass is a difficult one when it comes to blending with the Eclipse range. This is not because the subwoofer needs to reach far into the midrange, but because of the need to keep up with those crossoverless, single-driver point sources. Eclipse did an excellent job with the award-winning TD725sw, a huge square box designed to sit in the middle of your living room. And now it has replaced it with the TD725swMk2, another huge square box designed to sit in the middle of your living room. This time, however, it has a nice piano finish, rounded off corners, and some shiny trim rings around the bass drivers.

If that were the sum total of the years of development gone into the two generations of subwoofers, this wouldn’t be much of a review. Fortunately, the model revision gave Eclipse a chance to go back to the drawing board, improving transient response, and pushing the low pass filter down from 40Hz to 30Hz in the process.

The TD725swMk2 uses the R2R (rear-to-rear) dual-driver arrangement found in its predecessor, with two relatively small 250mm Kevlar/paper drivers, joined together internally by an aluminium shaft. However, unlike most subwoofers (but in line with the other models in the Eclipse TD range), the TD725swMk2 not only joins the drivers together by this shaft, but makes the shaft the only means of support for the drivers, and they effectively ‘float’ inside the subwoofer enclosure. The two spots on the aluminium bar are coated in a vibration-reducing material, which means no stray vibration from the outside world can get in, and the loudspeakers do not influence the cabinet. This is about as close to a perfect interaction (as in, ‘no interaction’) between loudspeaker drive unit and cabinet as it is possible to make.

 

The cabinet itself is a ladder-braced sealed affair, which accounts for a fair amount of the loudspeaker’s impressive 51kg weight. The internal 500W amplifier is Class D (specifically, it uses a Class D IcePower module), and the TD725swMk2 has two completely separate set-up systems, which allow the user to integrate the subwoofer into a hi-fi setting and a 5.1 system. It also means you can set these differently; one for ‘show’ one for ‘go’. In general terms, the crossover point for the ‘point one’ channel in a 5.1 system is typically set higher than it is for music (because ‘home theatre’ is about ‘theatre’ and ‘hi-fi’ is about ‘fidelity’), and the subwoofer connection is usually line in on a multichannel system and through the loudspeaker terminals on stereo systems.

The all-important ‘how does it sound’ question is actually one of the easiest to answer in this issue. It sounds like your speakers, only more and better. Perhaps more importantly, if there are any Quad Electrostatic owners reading this looking for some low-end reinforcement that won’t make your speakers sound like they have been injected with treacle, say ‘hello’ to the TD725swMk2, your new bass unit! This subwoofer reacts fast to music. It has the kind of rise time and decay that most dynamic loudspeakers would struggle to achieve (hence the Quad comment) and it integrates into any loudspeaker system, no matter how fast-paced.

This sets it apart from practically all subwoofers (we like the REL models for a similar reason, but this Eclipse shifts things up into high gear). And integration between main and sub speakers simply goes away in the setting up of the TD725swMk2. You need to approach this with due care and attention, but the bass fits so well, it might as well sound like one big loudspeaker. As a result, bass isn’t overt through the subwoofer, it just blends and extends the sound of the loudspeaker, and this typically makes the loudspeaker sound better further up the frequency response, too. It’s as if, being freed from the labours of bass, the loudspeaker itself can get on with doing what it does best: mid-range and treble. Even full-range loudspeakers improve here, although really large, really powerful full-range loudspeakers will tend to swamp the Eclipse performance.

The downsides to the TD725swMk2 subwoofer are purely physical. It’s big (basically, a 55cm cube), it’s heavy (51kg, as discussed earlier), and it’s best placed smack bang in between you and the loudspeakers. The good news is it can make a nice mirror-finish coffee table and even dub reggae won’t spill your drinks (don’t do this… eventually, one of those ‘the subwoofer has been drinking’ nights will happen, which ends badly for electronics). But it demands a fairly significant rethink of room layout and a very accommodating (or heavily medicated) significant other, if it winds up in a shared space.

 

I also imagine for some real bass-heads, the action of two 250mm bass units will never be bass enough. Deep bass generates almost atavistic respect from some, and those people demand air to be moved, trouser legs to be flapped, and eyeballs to be pressed into their sockets. For them, the ability to play bass with space, pace, and grace is as nothing as being able to loosen fillings at 30 yards. It can reach 20Hz, but the TD725swMk2 will never hit their B-spot. But that shouldn’t bother the rest of us, for whom bass is a simply a part of a greater musical whole.

Finaly, from a sound quality perspective, how does the mk2 differ from its predecessor? Perhaps the biggest change brought about by the revisions is improved transient response (Eclipse TD learned a lot from its revised speaker range), and that results in even snappier leading-edge resolution than before, which is saying a lot. It’s not a major change, and Mk1 owners will probably not feel the need to trade up, but the new and next generations of serious seekers of subwoofing now have a new champion in the TD725swMk2.

The Eclipse TD TD725swMk2 turns the loudspeaker world on its head. In most cases, integrating a subwoofer into a two-channel system means hoping that the sub can keep up with the main speakers. But with the TD725swMk2 in tow, it’s the other way around, and there are many loudspeakers that hold back what the subwoofer is capable of. Very highly recommended!

First Listen: Oppo HA-1 desktop headphone amplifier/DAC/preamp

As Hi-Fi+ readers know, we have been closely following Oppo Digital’s ongoing expansion in the high-end headphone and personal audio electronics marketplace.

First came the firm’s flagship PM-1 planar magnetic headphones (reviewed in issue 1xx), then a set of critically important optional ear pads that make the PM-1s sound even better (reviewed in issue 115), and now we have the long-awaited HA-1 desktop headphone amplifier/DAC (£1,199), which effectively completes Oppo’s high-end headphone system.

To jump right into the thick of things, let me say from the outset that the HA-1 is a pretty remarkable piece of kit, and one that—in the finest Oppo tradition—is not only chockfull of innovative features, but offers a generous helping of performance for the money. To lend some substance to these assertions, let me provide a brief verbal ‘walking tour’ of the unit.

As you might expect, the HA-1 leverages the considerable body of digital audio know-how developed by Oppo in the course of creating its award-winning and exceptionally versatile BDP-105EU audiophile-grade universal Blu-ray disc player (reviewed in issue 96). But in certain key respects the HA-1 DAC section ups the performance ante vis-à-vis the capabilities of the BDP-105-series players.

 

Specifically, the HA-1 provides a broader set of digital inputs than the BDP-105-series players: one front-panel USB port geared for use with smartphones, one rear-panel asynchronous USB power, a pair of S/PDIF inputs (one optical and one coaxial), an AES/EBU input, and an aptX-enabled Bluetooth interface. Moreover, the HA-1 provides two sets of analogue inputs (one single-ended via RCA jacks and the other balanced via XLR jacks), so that it gives owners quite a lot of flexibility in term of the types of sources it can support.

In keeping with long-standing Oppo practice, the DAC section of the HA-1 is based on the ESS 9018 Sabre32 Reference DAC. The HA-1 shares not only this ESS DAC but also DAC-section output stage circuitry with the firm’s time-proven Oppo BDP-105D universal Blu-ray player. The HA-1’s DAC section is nothing if not versatile and can therefore support PCM formats up to 32-bit/384kHz and DSD files ranging from DSD64 on up to DSD256.

However, where the BDP-105D is, first and foremost, a disc player, the HA-1 is designed to fill a much different set of roles. Thus, the HA-1 can be used as a conventional DAC in traditional high-end audio systems, or it can be used as an analogue/digital stereo preamplifier (with home theatre bypass), or as a high-powered and full-featured headphone amplifier that supports both digital and analogue inputs. Our bet, though, is that most buyers will gravitate to the HA-1 for use as the heart of (and central power plant for) their high-performance headphone systems.

The analogue amplifier section of the HA-1 is a fully balanced design that is based on discrete, Class A circuitry. As you might imagine, this mean that at idle, the HA-1 tends to run a bit warm, though not unpleasantly so.  But in exchange for that extra bit of heat, listeners enjoy the precision and clarity for which Class A circuitry is known, plus all of the gain/low-noise benefits that fully balanced amplifier circuits confer. Oppo takes an unabashedly purist approach to its balanced circuit topology, emphasising that “For digital audio, the signal runs in balanced mode all the way from the DAC to the output jacks.” Further, Oppo stresses that the HA-1 “Balanced analogue input is kept intact, and (the) single-ended input is converted to balanced at the input buffer.” 

 

In turn, the HA-1 provides both a single-ended headphone output (via a 6.35mm headphone jack) and a balanced headphone output (via a 4-pin XLR connector). Oppo points out that, “the balanced headphone output provides twice the voltage and four times the power of the single-ended output, enabling the HA-1 to drive the most power hungry headphones.” What kind of power are we talking about? In balanced mode the amp offers maximum output of 2400 mW @ 600 Ohms or 3000 mW into 32 Ohms, while in single ended mode the amp delivers maximum output of 600mW @ 600 Ohms or 3500mW @ 32 Ohms. Frequency response is quoted at 10 Hz – 200 kHz (+0B/-1dB) or an even more ruler-flat 20 Hz – 20 kHz (+-/-0.04dB).

Apart from audio performance, I think four other aspects of the HA-1 will be real crowd pleasers. First, the unit offers arguably the most refined fit and finish of any Oppo electronics component to date. Units are offered either in black or silver, with both versions offering the type of upscale anodizing and surface finishes rarely seen in such affordable products. Second, the HA-1 comes with a lovely, sturdy, and very easy to use remote control whose metal enclosure gives it a just-right touch of weight and heft in the hand. Third, the HA-1 provides an absolutely beautiful, colour user interface screen that is highly reconfigurable to suit the owner’s tastes. Apart from screens that provide basic setup and control functions, for example, the unit offers three display options: a settings summary screen, a bar-graph type spectrum display, or a display depicting an old-school set of VU meters. It’s very cool looking indeed. Last but certainly not least, the HA-1 comes with a really first rate User Manual.

I admit it; I’m an inveterate reader of product manuals and one thing I’ve learned is that product documentation for many contemporary audio components is woefully inadequate if not downright misleading. Why should you care? Because multifunction components such as the HA-1 offer so much control over such a broad range of features and functions that it pays to take the time to learn how the component actually works. The excellence of the Oppo manual stands in stark contrast to the documentation for some personal audio products that I’ve tried recently, where—I kid you not—at least one competitor’s manual described product functions that quite literally did not exist (how’s that for maddening?).

Since Hi-Fi+ will be reviewing the HA-1 in an upcoming issue, I won’t say too much about its sound in this blog, except to note that the HA-1 offers a richly revealing, intensely multi-layered sonic presentation coupled with more than enough power to make Oppo’s PM-1 planar magnetic headphones sing.  The jury is still out on whether the HA-1 does or does not offer enough oomph to make today’s most power hungry headphones happy, but that is a question we will address in our full-length review. For now, though, I feel comfortable in saying that the combination of Oppo’s PM-1 planar magnetic headphones with the firm’s HA-1 headphone amp/DAC will give its owners instant entry into the upper tier of contemporary headphone performance.

Watch for our upcoming Hi-Fi+ review of the HA-1, and in the meantime, Happy Listening!

Triangle Antal Anniversary loudspeakers

We are all a little late to the party. Triangle was founded in 1980 and this special trio of loudspeakers celebrates the company’s 30th anniversary. However, the range was completed last year. So, we’re only a bit late. It’s not like companies still using the Olympics sponsor logo across the UK, even though London 2012 was two summers ago. Instead, it’s the kind of trivial temporal detail you can always pass off with a shrug.

The simple fact is Triangle has something to celebrate as it enters its fourth decade. The loudspeaker brand has a distinctive, passionate approach to loudspeaker design, backed up by some significant R&D, and a brand loyalty that is second to none, both in its native France and increasingly autour du monde. The company building its own drive units in-house, something that sets the great apart from the good, ably demonstrates this commitment.

The Antal floorstander (and the Voce centre and the Comete standmount) have formed a consistent part of the Triangle range for the longest time. So, it’s only logical that these long-standing members of the party should be given the Anniversary treatment. Antal is a three-way, four driver floorstander design, which places great emphasis on mid-band clarity and speed, and efficiency. The Anniversary is no different, except it has a more solid, lacquered cabinet and a specific cellulose pulp midrange unit designed for the Anniversary model. It shares many of the common elements found in most Triangle midrange drivers, in particular the pleated suspension system, which the company helps lower drive unit colouration.

 

This custom midrange is joined at the top-end by the company’s own TZ2500 tweeter, a titanium dome device in a polished die-cast aluminium horn compression chamber. And bringing up the rear is a pair of the T16EF100SGC1 fibreglass cone bass units. These are perhaps best known among Triangle aficionados for having a vented voice coil, to help dissipate heat, allowing the stiff cone to at once be both more efficient and more rugged. None of these are what you might call ‘off the shelf’ loudspeaker driver designs, because Triangle doesn’t do ‘off the shelf’.

Those who have experienced Triangle designs will spot some common ground, as befits a celebratory design, rather than something designed to break with convention. With its 91dB sensitivity, it doesn’t need a power-house to drive it, but with a minimum impedance of 3.4 ohms, it stresses the need for quality rather than quantity in its partnering electronics. In use, we found it equally comfortable with valve and solid-state equipment. It’s a front-ported design, which ideally needs some space around it (a metre from the side and rear walls is good; a metre and a half is better). Triangle recommends this loudspeaker as being optimum for rooms of 30-50sqm (roughly between 320 and 540 sq ft), and I see nothing in the specs or the performance to challenge that recommendation.

Typically, we don’t pass too much comment on aesthetics of loudspeakers, in part because it’s both patently obvious (there are photographs to accompany the review) and because it’s largely a personal choice. There are exceptions, of course; you’d be hard-pressed to discuss a Sonus Faber loudspeaker without discussing the elegance of the design. But in the main, we leave that to personal taste. Not this time, though. Triangle’s big thing for the Anniversary models was to give them a really tasty piano lacquer finish, in rosewood, black, or – as we received – white. This really offset the dark grey plinth, with its front centring spike. White loudspeakers are really taking off in Asia, some parts of continental Europe, and even gaining traction in the somewhat conservative UK. Faced with the finish of the Antals, it’s not hard to see why. It sounds oxymoronic, but they manage to both stand out and blend in at once, and those who saw them all commented in the positive. I’ve seen some mixed blessings in white cabinets: designs that make you think ‘what other colours does it come in’, some that make you wonder what sort of vague yellow colour the designer confused for ‘white’, and others that look like Ikea was having a sale that day. Meanwhile, spending 10 minutes in front of the Antal Anniversary will make you wonder why more loudspeakers aren’t finished in white, and why should you bother with another colour. It’s easy to dismiss the significance of the aesthetics wearing the audiophile hat (that’s the one that rotates at 33 1/3 rpm and has valves dangling from it), but the reality is a lot of people who saw these speakers were predisposed to liking them from their style, even before a single note was played.

Of course, such a style-led exterior can only sway someone so far. The speaker has to step up to the mark too. And it’s here where Triangle so often shines. There is a directness and vividness that sums up the Triangle sound and the Antal Anniversary has no intention of letting the side down.

The easiest way of summing up the sound of the Antal Anniversary is that it works from midrange out. The mids are fast, fluid, and fun. The distinctive sound is very much geared to reproducing the live event, far more so than many of its peers, which opt instead for a more ‘dry’ studio-like sound. This is a deliberate action on Triangle’s part, but invites an interesting philosophical question: which is the more ‘accurate’. I find the presentation of the Triangle Antal Anniversary in many respects tonally and temporally closer to the original sound than many loudspeakers, even if those other loudspeakers are more faithful to the sort of presentation one might expect to hear in a typical studio. There’s no ‘smoke and mirrors’ here; Triangle is not using colouration to create a ‘better’ sound, but the Antal Anniversary highlights the excitement and energy of music, and can make some loudspeakers sound drab and dull.

This ‘live’ sound has a useful side-effect. It helps make less well-recorded music sound less hard, harsh, and aggressive than usual. I found several of the albums that I have to consign to the ‘ouch’ bin because of strong brickwall mastering were rendered more playable thanks to the Antal Anniversary. This is great because I really want to like Arcade Fire’s The
Suburbs
[Mercury] , but I find most of their albums almost unlistenable on a typical audiophile system. The Antal Anniversary can’t perform miracles, but it does make the best of a bad job. I suspect this is a pragmatic solution to an increasingly stiff problem; if we keep making equipment that highlights the limitations of most music released in the last 15 years, we light yet another fuse on audio’s demographic time-bomb. Whether through accident or design (and I strongly believe it’s the latter), Triangle focuses the Antal Anniversary on the enjoyment aspect of the music playback, and while this might ‘Irk The Purists’ (one of my favourite Half Man, Half Biscuit tracks, incidentally) it’s a good thing for audio because it invites new listeners to the club. We could all benefit from that… and being a little less dogmatic about the ‘fidelity’ part of the whole ‘hi-fi’ thing.

 

Rant mode disengaged. The Antal Anniversary extends its live sound fun zone to the top and bottom of the frequency range, with a clear and clean and ‘extended’ treble, and a tidy, enjoyable bass. The word ‘extended’ here is often misunderstood, it doesn’t mean ‘more treble’, it means ‘better treble accent’. It means you are more able to hear the music rising into the upper registers, better defining horn sections and the upper regions of pianos and wind instruments. Meanwhile, the bass is deceptively big and powerful and entertaining. It’s not transient-led and rim-shot precise, but it gives a sense of order and circumstance to the music that makes it hard not to like.

There are two ways of making a good loudspeaker, in my opinion. The first is to make one that satisfies the most number of people possible (nothing wrong with this, and it is one of the reasons why brands like Bowers & Wilkins are so successful). Then, there’s the other way; make something idiosyncratic, but good. Not everyone will like it, but those who do, absolutely love it. And that’s what Triangle does so well. It makes loudspeakers that don’t tow the party line, but those who get the sound (and, in fairness, it’s a sound that is extremely easy to ‘get’) will not be satisfied with anything else. Put simply, if you listen to most loudspeakers and think they lack a spring in their step, the Antal Anniversary could be your next loudspeaker.

Epic Winning!

2014 is slowly drawing to a close. There’s still Thanksgiving, Christmas and New Year to get through, but already we’re thinking to 2015, and some of the fabulous things we will be giving away.

We take a unique line among audio journals, in that we live up to our truly international standing. We insist that manufacturers do not limit the scope of a competition prize to one country, because Hi-Fi+ doesn’t think in terms of one country. Yes, we are based in the UK and we dream in pounds, pennies, and pints (especially pints), but we know Hi-Fi+ in all its guises is read worldwide, and we don’t think it’s fair that audiophiles should be denied the chance to win some of the best prizes we can find just because of geography.

This does mean our competitions tend to take longer to run, to give international readers a fair chance of entering a competition, but we think it’s worth it, and so do those lucky winners in far-flung lands. So, although we still have more competitions to run this year, they will finish and be judged next year.

Recently, however, we ran a local competition, for those who attended the National Audio Show at Whittlebury Hall in the heart of England. Those who signed up to this newsletter at the show were automatically entered into a Free Prize Draw, where they could win one of five excellent iFi products. Congratulations are therefore due to Malcolm Summers, who wins an iFi Micro iDSD portable headphone amp, preamp, and DAC. Congratulations are also due to our other lucky iFi winners; Doug Dickinson, Cosmo Hynds, Terry Cymbalisty, and Jeremy Honeybun.

And while we are looking to winners, here’s a list of some of the lucky recipients of our competition prices in 2014:

Don Howden of Alberta, Canada won the excellent Ayon Audio Orion III integrated amplifier

Gerard Peters of London, England won the HiFi+ Signature pair of superb Wilson Benesch Square One Loudspeakers

And as of this week, Lucas Armstrong of Wellington, New Zealand won a fantastic pair of Final Audio Design Pandora Hope VI headphones.

We love to sit and listen to some of the finest audio equipment that has ever been made. But we love to share it out, too. Find out what we will be sharing out in our next competitions, soon!

Harry Pearson, HP and The High-End As We Know It

Editor’s Note: HP is significant in the development of Hi-Fi+ in that he was a friend of, source of inspiration to, and (in a sense) a role model for, Hi-Fi+ founding editor, Roy Gregory. In an indirect way, HP helped to draw Tom Martin’s attention to Hi-Fi+, which eventually led to a decision on Martin’s part to purchase and develop Hi-Fi+, just as he earlier had done with TAS.

Additionally, HP was notoriously reticent to see his picture in print, and as a mark of respect, we have run through the company archive to find what he might have considered his best side – some of the classic TAS covers!

I first became aware of Harry Pearson, without exactly realizing it, in the spring of 1973. I was in my first year at university in the U.S., and I happened upon a tiny classified ad in Rolling Stone magazine promising a new, critically rigorous, audio magazine. As a budding audiophile I immediately sent in my check for what I suppose was something like $8, even though that was quite a bit of money for a student in those days.  A few months later, I received Issue 1 of The Absolute Sound (or TAS for short).

To understand the impact that Harry Pearson (or HP as was his nom de plume) and TAS made on high-performance audio, you need to take your mind back to those days. You need to go back because now it is hard to imagine the advent of a single magazine making such an impact. But at that time, at least in the U.S., there was only one publication attempting to describe, in detail, the sonic differences between different pieces of audio gear. That publication was Stereophile, edited and mostly written by the great J. Gordon Holt. Unlike the modern Stereophile, JGH published irregularly. And that is putting it mildly, because readers would sometimes wait a year or longer between issues. With a hobby that was really beginning to take off, that simply wasn’t enough to either cover much of the available equipment or to keep up with new technological developments.

HP’s TAS stepped into that void. And though HP was hardly publishing on an exact schedule, he generally managed to get at least three issues out per year. That kept audio junkies in the game, though I have to say there were times when the wait for a new issue was excruciating.

A outside cover was a canvas to HP: the last pages of TAS #23 and #28

But once an issue arrived, oh how it was devoured! On the day of arrival, I would sequester myself in my dorm room or bedroom and just begin reading. A day or two later, the entire issue had been consumed—every word—and some re-reading began. If you have children or grandchildren who were readers of the Harry Potter series, you will likely have witnessed similar behaviors. No more avid study would greet the arrival of a newly discovered and authentic book of the bible at an evangelical prayer meeting.

 

HP built a publication whose success at the time was built on more that just satisfying a real hunger, though. As a newspaper journalist, HP not only wrote well, but he had a great sense of the story. And he surrounded himself with other writers—JWC, PHD, JN and more—who were, while certainly not his equal, quite capable of telling the tale of music as delivered through high-end gear.

HP studied psychology at Duke University and from that he developed a philosophy about audio reviewing that was a game-changer. Harry’s idea was that the human perceptive apparatus could be trained to objectively observe the distinctive performance characteristics of audio gear. It not only could do this, but was (and is) the best “test equipment” for that job. What then is needed is a standard for using one’s hearing to judge what is good and what is bad. The standard HP proposed, and then built the magazine on, is the sound of live, acoustic music played in a real space. That sound is the reference to which reviewers should compare the sound of audio equipment when describing and judging its performance. HP called that reference “the absolute sound”. Naturally, he chose it as the title for the magazine as well.

Revealed wisdom for audiophiles!

And that philosophy was essential to the development of high performance audio. Without a goal, and a goal that is understood and shared by much of the audiophile consumer base, the audio world would likely have pursued many competing goals and consumers would likely have been confused about what the game was. We would have had an industry in which companies made products that they believed to “sound good”, but where they and consumers lacked a clear way to consider how to make them sound better. Because without a standard, it is hard to know the difference between good and better. It is much easier to understand inaccuracies in matching the sound of live music, and work to eliminate them. And, certainly in the 1970s, the differences between live and reproduced sound were profound, which is to say there was a long way to go and much development possible.

 

To go with this philosophy, HP and team developed a language to convey what they were hearing. They understood that they needed not only to perceive how music sounded on the gear they were reviewing, but they also had to communicate it in an understandable way. And since objective observation, with the exception of JGH, had largely been missing in audio reviewing, the necessary lexicon was largely missing too. You don’t need, for example, a word to convey “soundstaging” until you have observed the phenomenon and thus need to convey the idea to readers.

HP’s amazing achievement was not only starting a magazine (a difficult operational and financial task, to be sure) but also starting it with a staff and a direction that made it almost immediately influential. HP didn’t just start a magazine; he started a movement. There is no doubt that others at this time were on the same track. Certainly Bill Johnson and Arnie Nudell and Jim Winey and Bob Carver and Mark Levinson and many others were already working on this same project. HP and TAS were pivotal in turning it into a community on a mission.

Fast forward about 25 years. Stereophile, led by Larry Archibald and John Atkinson, was now the regularly published leader in the field. And Harry was struggling to get TAS out not just on time but at all, having lurched from financial crisis to financial crisis at least one time too many. I vividly recall wondering when the next TAS would arrive and if something more serious was wrong. Then, some months later, a new issue arrived and upon opening it and reading the letter from the editor, I found that Harry was indeed in dire straits and inviting readers who might be interested in investing to call him. So, I did. I told him I was interested in buying the magazine. I may have been the only caller, so we agreed to meet.

The Absolute Sound reborn, after 25 years

I flew to Sea Cliff, NY with Mark Fisher, Harry’s proposed publisher. For me it was a fascinating meeting. Of course, even though I held most of the cards, I was more than a bit nervous meeting “the great man” of my early adulthood. But Harry, without contrivance, managed to stage a meeting at which I was at once impressed and charmed. As others have observed, Harry had a great, deep voice. He also spoke to a significant degree in pronouncements (“I am at the height of my powers”, “this is the finest sound ever obtained from that cartridge”, etc.). He was quite willing and able to get down to a discussion of the core philosophical elements that make TAS what it is and that, like the constitution, must be protected. He interlaced references to wines and Carnegie Hall into casual remarks. And yet, he set the meeting up in a local pancake house that hadn’t altered its architecture since 1965. He was never rude, exuded hope, and clearly wanted help.  It was a bit like having a pint with the Queen at the local pub while discussing your views on foreign policy. Odd, and yet engaging.

I learned a lot from Harry in those days. Harry and Sallie Reynolds (who was essential to making the editorial department run) knew people and knew how to get things done with limited resources. They had a deep sense of what readers cared about and Harry had a nose for interesting gear. Harry had some good relationships in the industry, too.

 

Harry could also test a relationship in surprising ways at surprising times. Almost everyone who knew Harry has some specific memory of this. In my case, he often seemed to carry his journalistic (“don’t trust the subject”) sensibilities into realms where they didn’t belong. We had frankly unnecessary work to do to deliver reviews and return equipment on time.

TAS Then and Now. From pamphlet to journal to magazine.

We (eventually) worked through or around those issues. Still, I don’t think Harry was ever happy without the formality of being in charge. It wasn’t that he was a control freak. And it wasn’t only that he had created TAS and now others were shaping it—he actually seemed to enjoy working with others. Mostly, it was that Harry truly was “a great man”, and simply being “an important man” in the TAS structure didn’t fit his identity.

I don’t think that should have mattered. Nothing could have or will change Harry’s greatness. Harry, wherever you are now, I hope you realize, with some finality, that you were always a great man to a great many of us.

Thanks.

Aaron No 22 Cineast preamp and No 3 Millennium power amplifier

This is Aaron’s pre-power system, but it’s a system with a twist. While the No 3. Millennium power amplifier is a stereo design, the preamp – the No 22. Cineast – is designed to handle multichannel inputs alongside stereo line sources. While that would normally have audiophiles reaching for the ‘off’ button, the twist is there is no digital processing going on inside the preamp. It simply handles six channel sources, in the same way it handles two channel sources.

Aaron is the value end of German high-end brand Aaron & Sovereign. The company has both a direct mail and distributor-based way of working. Direct mail includes a financing plan, which makes these affordable amplifiers easy to acquire. However, it also provides very scant information on its site, preferring instead for prospective clients to request a PDF datasheet. I’m not totally convinced of this idea, as I feel it loses potential buyers at the starting gates, but it does sift out those with only a passing interest.

As discussed, the Cineast preamplifier is a multichannel preamp, with two sets of six channel inputs alongside the six stereo line inputs, and one set of multichannel outputs (for two-channel users, plug your power amplifier into the ‘FL’ and ‘FR’ channels). Any digital surround sound processing is performed in the source component itself, the Cineast’s multichannel functions are limited to individual channel attenuation and the provision for turning off specific channels. Controls are simple; left knob runs through the sources, and if you push the knob, it goes into set-up mode, while the right hand dial controls volume and pushing it in puts the preamp into standby. A large, two-deck fluro display sits usefully between the two knobs. There’s a chunky remote control, and a pithy Aaron identifier plate on the top panel.

The Millennium has the same dimensions, save for the control knobs (actually, control cones). The amp itself is extremely well made, featuring all discrete, hand-selected and matched components, with no capacitors in the short signal path. The big bank of capacitors under the hood are in the power supply, and there’s a lot of air between the large toroidal transformer, the power regulation block, and the twin output stages. These output stages work in a collector-follower circuit and the amp is capable of delivering 100W per channel into eight ohms, 180 into four and right down to 550 into one ohm. Both amplifiers can be powered on permanently (and don’t draw a great deal of current in standby mode), and are fully conditioned and at their best 48 hours after being plugged in. They don’t run warm, or make a noise through the loudspeakers when not in use. In other words, they are the perfect audio houseguests.

 

There’s a trend in audio electronics to focus on the ephemera and miss the basics. The Aaron equipment resoundingly bucks that trend. These aren’t packed to the gills with the most expensive components; this is good, solid equipment, built well in a no-frills manner. What they deliver instead of a bit of ‘bling’ is sound good.

I slotted the amplifier duo in a system comprising the Audiocom-modified Oppo 105 player (for disc and Ethernet-streamed music from my Naim UnitiServe), and an original SME Model 20 with Benz Micro SLR cartridge feeding my RCM Audio THERIAA phono stage. These were fed to a pair of Wilson Duette II loudspeakers. Amplifier comparisons were mostly from integrated solutions in and around the same power/price class (Burmester, Devialet, Jeff Rowland, etc.), but notable substitutions have been duly noted.

Like the external appearance of the Cineast and Millennium, there’s a sense of down-to-earth confidence about the Aaron sound. And that applies regardless of the scale or genre of music played. This is an acid test for a component for me; yes, the amplifier that makes musical magic when hooked into the jazz scene is lovely, but only if it does the same thing for any other kinds of music. Unfortunately, there’s a move to tailor the sound of electronics (consciously or not) in one direction, and currently that’s an obsession with detail and soundstage, or an emphasis on leading-edge resolution. The Aaron amps take a more measured line on music replay, and it’s a refreshingly honest one.

Don’t mistake this for meaning the amplifiers are incapable of producing sweet jazz tones, expansive soundstaging, fine detail, or precise, tight rhythm. They are more than capable, in fact. But it’s the spread of sound that is what the Aaron duo do so right. You play something guaranteed to trigger discussions about detail and soundstage – Dexter Gordon’s Go [Blue Note] for example – and you find yourself also listening to the timbral properties, and the solidity of the instruments in the mix. You play something with the most obvious beat – ‘I Misunderstood’, from Richard Thompson’s Rumor and Sigh [EMI], which was a staple for many a ‘tune dem’ in the later Flat Earth years – and you find yourself also listening for the soundstaging, the inner detail, and could end up discussing macrodynamics and microdynamics in a way that would get you drummed out of the ‘Pace, Rhythm, & Timing’ club. In other words, the Aaron duo presents the music in an intrinsically correct manner.

If pressed, I can see why the Aaron amps are sort of associated with rock music replay. The weasel words in the above sentence are deliberate, because the rock association is not a deliberate position of the Aaron, more a lack of flexibility in its rivals that shows up in the rock canon. Nevertheless, the Aaron sound is powerful, solid, and perfect for playing graunching guitar riffs at a fair lick. It’s a slightly ‘dark’ sound too; not rolled off, not brooding, but also not bright and steely in the way many amps can sound with rock. However, the Aaron sound doesn’t suffer musical fools gladly, and signal compressed sounds are not prettied up. This is not a ‘warts an’ all’ presentation, but honest enough to show up just what heavy-handed signal compression can do to a piece of music. Even that ‘now’ stalwart of audio demonstrations, ‘Royals’ by Lorde [Pure Heroine, Virgin], shows itself as thin and loud… unless you play the LP version.

 

Of the two components, I find the Millennium the star of the show, although it’s a very close run thing. It came down to running the Cineast and the Townshend Allegri (the most transparent and least obtrusive preamplifier I know of) in quick succession. Both Aaron devices were great products, but the Millennium had huge amounts of power on tap. It can drive absolutely anything (even down to one ohm, so even the most beastly loudspeaker is dispatched without the Millennium turning a hair), and it can drive it with solidity, exceptional dynamics, and slam. That’s a word you don’t hear much in audio today, because everyone seems more obsessed with soundstaging, but play some Who records at a fair lick, and the underpinning of Keith Moon’s ‘Unleash Hell’ method of drumming and John Entwhistle’s super-fast, super powerful bass, are both rooted in place. That slam is better expressed with the Allegri+Millennium combination (in fact, the duo works so well, Townshend should consider using the Aaron amp as a handy power amp recommendation), although in great fairness the Cineast does not lag far behind the Allegri. Given the Allegri is arguably one of the best preamps money can buy, it shows how good the Cineast can be.

My concern here is people will miss out. Audiophiles will see the word ‘Cineast’, see those six channel inputs and outputs and jump to the wrong conclusion. Like the Millennium, the Cineast is every fibre a hi-fi preamplifier, and in our spendy world, a good value one at that.

AURALiC GEMINI 2000 headphone amp/DAC/stand

Two of the first AURALiC products reviewed by Hi-Fi+ were the firm’s superb TAURUS Mk II balanced-output headphone amplifier (£1,499) and VEGA digital audio processor (£2,890). Terrific performers though both units are, they are priced somewhat beyond reach for many ‘headphonistas’—even ones who care very deeply about sound quality. Recognising this, AURALiC founder and chief designer Xuanqian Wang set out to build an elegant, one-piece headphone amp/DAC solution that would offer much of the performance of the TAURUS Mk II/VEGA pair, yet would sell for less than half the price. The result is the GEMINI 2000 headphone amp/DAC/stand (£1,890), which—apart from its technical merits—is a lovely audio Objet d’Art.

The most visually striking part of the GEMINI is the stand section, the design for which has been licensed from the Swedish firm Klutz Design (whose famous headphone stand is known as the CanCan).  The tall, curvaceous CanCan stand has long been a personal favourite for several reasons: first, it is beautiful; second, its gently rounded top section provides great support for headphones without creasing or crimping their headband pads; and third, its clever forward-facing posts serve as a handy ‘spool’ around which signal cables can be coiled for safe-keeping (you’d be amazed to learn how many headstand stand makers forget all about this important feature, leaving cables coiled up in a heap on the table or floor).

The Klutz stand design features a tall, slender, sculptural ‘tower’ with a rounded top section: the tower, in turn, is mounted upon a thick, cylinder shaped, polished metal plinth. The GEMINI closely matches the general look and feel of the Klutz stand so that, from a distance, you could mistake one product for the other, but as you draw closer to the GEMINI salient differences soon become apparent. First, near the bottom of the GEMINI’s stand section, one finds an inset, forward-facing, single-ended 6.35mm headphone output jack and a rear-facing, balanced-output, four-pin XLR headphone output jack. Then, on the side of the GEMINI’s plinth one finds a rotary, thumbwheel-type volume control (labelled, somewhat whimsically, the ‘Niceness’ control), plus two polished metal pushbuttons—one serving as the On/Off switch and the other as an input selector switch. Plugging headphones into the GEMINI’s front-mounted 6.35mm jack also automatically switches the unit on.

 

Inset within the top surface of the plinth are three groups of miniature red LEDs indicating, respectively, the input selected, the sampling rate and format of the digital file being played, and the volume setting chosen. On the rear of the plinth is a recessed pocket that houses a DC power inlet socket (the GEMINI comes with a substantial wall wart-type power supply), a TOSLINK port, and two USB ports—one for general-purpose use and the other specifically for connections with Android-type smartphones.

The recessed pocket also incorporates an SDXC card slot, on which AURALiC provides the device driver required when using the GEMINI in Windows environments. This is a truly handy feature, in that it means the GEMINI can be used with virtually any Windows PC—even those that may not have Internet connectivity. AURALiC also points out that the SDXC card provides a minimalist card reader/music player app, so that the card can also be used for music storage and playback  (but note, we were not able to evaluate this function as our review sample GEMINI did not come with the requisite player software installed on its SDXC card).

The entire DAC/amp circuit of the GEMINI fits on a compact semi-circular printed circuit board (PCB) that fits within the tight confines of its cylindrical metal plinth: a plinth that measures just 26mm thick and 140mm in diameter. When one sees a close-up photo of the GEMINI PCB fully populated with its more than 500 tiny surface-mount components, it is almost like looking at an aerial photo of downtown Beijing. Quite seriously, the GEMINI amp/DAC circuit board is a marvel of miniaturisation and space efficiency.

The DAC capabilities of the GEMINI are similar to those of the VEGA, although with somewhat less elaborate user control setting options. Thus, the GEMINI, like its bigger brother, can handle all PCM formats from 44.1kHz to 384kHz at bit depths up to 32-bits. Moreover, the GEMINI can decode DXD, DSD64, or DSD128 files with ease. Like the VEGA, the GEMINI uses a high-performance clock (though not as high performance as the one in the VEGA) and provides sophisticated digital filtering algorithms (though not multiple user-selectable ones as in the VEGA). Even so, all the important basics are present and accounted for.

The Class A amplifier section of the GEMINI 2000 provides fully balanced circuitry and both single-ended and balanced outputs, generating a substantial 2000mW from 20Hz – 20kHz at less than 0.001% THD. As you can imagine, this level of output generally proves adequate for even today’s most power-hungry top-tier headphones.

 

Listeners who neither need nor want the high output or fully balanced amplifier circuitry of the GEMINI 2000 will be pleased to learn that AURALiC offers the cost reduced but visually and functionally identical GEMINI 1000, which offers slightly different cosmetic options than its bigger brother, and non-balanced amplifier circuitry, with output of 1000mW at less than 0.002% THD. Note, though, that neither GEMINI model incorporates AURALiC’s signature ORFEO Class A analogue amplification modules (as used in virtually all of the firm’s full-size components); plainly, this was a necessary design choice given both cost and space constraints (the ORFEO modules being, I think, too large to fit inside the GEMINI’s plinth).

During my listening tests, I used the GEMINI with a Lenovo PC running Windows 8 and jRiver Media Center 19 music playback software, along with a host of headphones including the Audeze LCD-3, HiFiMAN HE-6 and HE-560, and Oppo PM-1. Music included a mix of standard and high-res PCM and DSD files spanning a wide range of musical genres.

One observation that struck me early on, and that has stayed with me ever since, is that the GEMINI sounds more like the TAURUS MkII/VEGA pair than not; the sounds of the two products are not identical, but they are similar and surprisingly close in overall performance. This, then, is the real draw of the GEMINI (apart from its ever-so-cool appearance); it gives you much of sound quality of AURALiC’s flagship headphone amp/DAC pair, but in a one-piece unit selling for a fraction of the price.

What exactly constitutes the AURALiC ‘house sound’? Well, three key ingredients would be articulacy, transient speed, and resolution (or ‘focus’). All three of these elements are very well represented in the GEMINI. To grasp this, try listening to some high-res files through a good, competing single-chassis DAC/amp and then switch to the GEMINI, noting the differences you may hear. When I tried this sort of comparison, using iFi’s excellent new portable Micro iDSD amp/DAC, I found the iFi acquitted itself admirably (especially in light of its modest price), but stepping up to the GEMINI brought me to a realm where timbral and textural information suddenly became much more tightly focused, more vivid and explicit, and almost palpably three-dimensional.

 

The sonic effect was not unlike looking at an object through a good standard-length lens and then suddenly looking at the same object through a top-shelf lens that offers tight macro-focusing capabilities. There is that same breathtaking sense of suddenly being able to ‘zoom in’ to get up close and personal with the details that matter most—the pleasurable sense of actually knowing, rather than merely imagining that you might know, what’s really going on inside your favourite recordings. This capability is what sets the GEMINI apart from many of the products I’ve heard that sell for roughly half its price. You pay a little more for the GEMINI, but you very definitely get what you pay for (and then some).

Another element of the AURALiC ‘house sound’ is the ability to keep transducers under firm control, yet without imparting a sound that seems overly tightly wound or ‘over controlled’ to the point of cold sterility. To appreciate what I’m getting at, here, try listening to bassist Avishai Cohen’s “Bass Suite No. 1” from Adama [Stretch Records] and listen closely to the sound of Cohen’s acoustic bass as reproduced by the GEMINI. On one hand, the presentation has a light, lithe, and agile quality that gives you access not only to the fundamentals of the instrument, but also to its richly coloured upper harmonics, not to mention subtle fingering sounds that can tell you so much about Cohen’s masterful technique. But, unlike some ‘high definition’ but also overly lean-sounding amp/DACs, the GEMINI also captures the instrument’s weight, gravitas, and deep, woody, earthy growl. Another way of saying this, I suppose, is that the GEMINI not only gives the substance and body of an instrument’s or a vocalist’s signature sound, but also the myriad small details and textures that spell the difference between good sound and sound that, at moments, approaches realism.

What can’t the GEMINI do? Well, good though it is, relative to AURALiC’s TAURUS MkII/VEGA pair, the GEMINI is a little less finely focused and resolved, not quite as low in noise, and—when push comes to shove—not quite as powerful. Obviously, there are also a number of features and functions that have been omitted, as both the TAURUS MkII and the VEGA are, by design, set up so that they can be used as standalone preamplifiers (or in the case of the VEGA, as a standalone master DAC) within full-sized hi-fi systems. In contrast, the GEMINI is only and always a headphone-centric product (which is no bad thing in my book).

Sonically, I would say the one ingredient one might miss in the GEMINI vis-à-vis the TAURUS MkII/VEGA pair would be the absence of the ORFEO Class A analogue amplification modules used in the more costly components. Honestly, those ORFEO modules are downright magical (not unlike the Neve recording consoles whose sound and circuitry they mimic), and what they buy you is a sound that to my ears is as focused and well-defined as any self-proclaimed ‘high resolution’ product, yet is as effortlessly natural, comfortable, and easy to listen to as any so-called ‘high musicality’ product. The GEMINI does an excellent job of channelling many of these ORFEO-like qualities, but at the end of the day there’s nothing quite like having the genuine article at hand.

 

Still, I believe the GEMINI will be all the headphone amp/DAC that many listeners—even very critical listeners—will ever need or want. The neat part is that, unlike many traditional audio components, the GEMINI exudes an elegant and yet gently whimsical ‘lifestyle’ appeal all its own. For what it is and does, the GEMINI is arguably very well-priced, and the fact that it serves as a terrific-looking and highly functional headphone stand only makes the deal that much sweeter.

Devialet Ensemble system

Devialet has received a lot of (mostly extremely positive) press since its launch. The company’s continual development and an increasing range of designs has made it one of the most successful newcomers in high-end audio today. However, its new Ensemble system represents a radical departure, because it extends the ‘does it all’ approach to the speakers. This is a turnkey system, and really rather good it is, too.

Ensemble comprises the Devialet 120 – the entry point to the concept – coupled with a pair of custom-designed Atohm GT1 loudspeakers. These two-way, rear ported designs are, in principle, no strangers to the pages of Hi-Fi+ (we reviewed them in issue 93), but the Devialet-derived version removes the logos from the front, and the room-matching boost/cut dial from the rear panel… for reasons that will become clear soon. From experience, the GT1 on its own has a reputation for speed, precision, and fun.

The Devialet 120 is fascinating in its own right. Normally, when brands try to make a lower-cost version of a popular design, they play an electronic engineering version of the balloon game, sacrificing subsystems in order to achieve the right financial altitude. On the surface, the 120 follows the same path, but in fact it’s closer to a completely new design in its own right. Yes, it still uses the same ‘ADH’ Class A/Class D hybrid core concept, the same 24/192kHz ‘Magic Wire’ internal DAC architecture and uses the same firmware as the larger models, but it’s a completely new design, intended for lower cost applications than the 200/400 and the D-Premier/250/800 models. How it does this is by limiting flexibility a little. So, there’s just one line/phono input, four
S/PDIF inputs, Ethernet and USB, and no provision for output or dual mono operation (analogue pre-outs for power amps are an option though). The phono stage is less freely configurable than the bigger models. And, the 120W amp is on a slimmer chassis. Naturally, it can support the company’s own AIR streaming (via WiFi or Ethernet).

There are two big pieces in the jigsaw puzzle that have slotted into place in the last two updates; they apply universally to the Devialet concept, but are worth stating here. The first is the bi-directional USB option (from firmware 7.1.1); if you simply use the USB cable to feed digital music from computer to DAC and amp, this is perhaps not a big issue. On the other hand, if you have a turntable, a computer, and a program like Audacity, your Devialet just became the easiest high-performance way of ripping your vinyl. No more scrabbling round for a suitably good quality analogue-digital converter or unplugging your phono stage from the amp for the best possible performance; one box does it all. And, with metadata population programs like Collectorz, the whole process of archiving your albums suddenly moved out of ‘chore’ valley. The phono stages in the ‘better’ and ‘best’ Devialet options improve on the quality of the 120, but not by a significant margin (unless you are fond of amp-strangling low load MC cartridges).

 

The next is SAM, short for Speaker Active Matching. As the name suggests, SAM helps match the output of the Devialet to the input of the loudspeakers, although ‘active’ in this sense means ‘adapting to the demands of the loudspeaker in real-time’ and not ‘bypassing the passive crossover network to directly drive the loudspeakers’. This works by using a SHARC chip to model the characteristics of the sub-150Hz performance of the loudspeaker and apply those parameters to every sample it receives from the digital (or converted analogue) sources. It controls the loudspeaker in the phase domain (meaning the loudspeaker is phase correct from top to tail), carefully controls the excursion of the woofer (which has a knock-on effect of making it reach deeper than it has any right to) and provides robust heat protection by knowing the thermal limits of the loudspeaker. All these aspects of SAM sit over and above the ‘raw’ sound of the Devialet system, and if switched out, has no effect on how the 120 sounds.

The ‘how it sounds’ part for the 120 is extremely easy. It sounds like a Devialet; cool, calm, and collected. It’s extremely detailed (but not in an analytical, detached, or musically dead way), extraordinarily precise, stunningly focused, and produces music from an unearthly silence. It is a hard sound to pin down because it is so precisely right, and as a result you end up describing it in terms of what it isn’t like, because most other things wind up sounding as if they are artificially laying on the warmth or the bounce or the soundstaging. The 120, like all the models in the Devialet range, tells it like it is.

And if you think the 120 is somehow compromised by its place in the Devialet hierarchy, or that 120W power rating, guess again. This gives its all, and never shows its limitations. More, when you factor in the speaker control SAM bestows on a loudspeaker, if you are running out of steam with the 120 you are either determined to deafen yourself, trying to get full-thickness sound out of a small speaker in a vast room, or have hooked your Devialet to a couple of pieces of concrete masquerading as the drive units of a loudspeaker. The 120s bigger brothers bring more flexibility in terms of cartridge matching, more connectivity for both analogue and digital sources, and the ability to add enough power to drive a pair of speakers to PA levels. If you do a tight head-to-head comparison between the 120 and 250 (as I did), there are also slight advantages in terms of detail resolution, focus and bottom end drive. If you are using a loudspeaker that does not form a part of the SAM-approved list, those advantages become all the more noticeable, and the 250 shows it has all that extra muscle on tap. And, we effectively summed up the Atohm as fast, precise, and fun both earlier in this review and in our review of the loudspeaker back in issue 93.

SAM is like firing an audio system’s afterburners. I kept channelling Scotty from Star Trek when listening to the Ensemble. “Ye canne change the laws o’ physics, Cap’n…” and yet a loudspeaker that (by virtue of its box) shouldn’t be capable of delivering much below about 50Hz is reaching down to the bottom octave with ease. This comes down to SAM’s ability to act as heat protection system combining with its ability to manage cone excursion in the speaker. I’m actually struggling to express this without recourse to using the single, guttural, extraordinarily Anglo-Saxon word that gets uttered the first few times you press the SAM button. In fact, you only need to press it once; you only repeat the experience for a laugh.

The physics isn’t wrong; rather we’ve been looking at the way loudspeakers can work in the wrong way. Suitably controlled to this level of sophistication, SAM works wonders. The loudspeaker reaches down to a low point far lower than you might expect (as in, just beyond its resonant frequency). This has been ‘notionally’ possible from a loudspeaker system, just never realised in the flesh. What this means in simple terms is true, taut, and really deep bass that you think must come from a loudspeaker with almost twice the cabinet volume and drive unit size. Walk someone blindfolded into the room with Atohm/Devialet GT1 speakers playing and SAM switched in and they will probably think they are listening to something closer to a pair of big Tannoys. Remove the blindfold and that Anglo-Saxon word jumps out again. If it’s your room and your system, it’s said with a big smile, too.

You will reach for those big bass pieces of music, be it Bach’s Toccata and Fugue, or Burial, and most will wonder if there’s a route back from all that bass. In fact, what you are also hearing is the corrected phase response, and in a two-way like the Atohm, that makes for a sound that is utterly musically faithful across the board. It’s a studio-like precision, but without the studio-like scalpel through your music. Female voice in particular takes on an ‘in the room’ vividness that draws your attention in a way few other systems at the price can approach. And yet, I also know SAM has a similar transformative power that can be put to other loudspeakers big and small. Put simply, the Devialet Ensemble system allows the loudspeaker to be all it is capable of being, but it also shows there is a lot more to get out of most loudspeakers through SAM.

Is there a trade-off to SAM? OK, so if your idea of ‘loud’ is the police kicking in your door to tell you to turn the music down, then the trade-off is you can’t drive this into clipping and end-of-driver-life sessions are a little more subdued. And those who set their watches to 1970s time seem to find the very idea of extending the performance of a loudspeaker this way somehow ‘tampering’ with the music. For myself, I find the idea of sacrificing this much improvement over the sound for a notional dislike of the idea of signal processing to be ‘somewhat’ self-defeating. The advantages to SAM (phase correction, the fact that you can only break your drive units by head-butting them, the transformation of a bookshelf loudspeaker into something that sounds like it should be the size of a Dalek, the way that interacts with the room meaning less treatment, and the sheer sense of control it bestows to the sound in general, not just the bass) in my mind vastly outweigh any misgivings about ‘inserting the Devialet sound between the samples’ and other non-arguments put about by the suspicious and the cynical.

The Ensemble system is perhaps one of the best ways to experience both what the Devialet thing is all about, and especially what SAM does for a system. Where in previous firmware versions, you could tailor the amount of interaction SAM produced, it’s now either ‘engaged’ or ‘disengaged’ (and you can switch between the two states on the remote handset, if you delve deeper into the online configurator). I’d like to say the effect is profound, but that seems like understatement. It controls and energises the loudspeakers in a way that makes even active drive seem a little flaccid. The Atohm GT1’s are already fast, taut sounding loudspeakers, which makes for a good mix with the precision and detail of the 120, but the synergy and bass produced by SAM makes the match almost unassailable.

 

What makes this Ensemble system so good, and so important is that it is the ultimate turnkey system. If you have a small to mid-size room, this is so natural a solution, you would be hard pressed to improve upon it on fairly basic terms of bass control, depth, and precision. That this holy trinity of low-end goodness creates ripples of improved performance right up through the audio band only serves to reinforce just how good this system is.

There are four conclusions to be drawn from this. First, if you have a loudspeaker on Devialet’s ever-increasing list of SAM-ready loudspeakers, you owe it to yourself to hear what a Devialet can do for that loudspeaker. Secondly, if you have a Devialet and are in the market for a pair of loudspeakers, the list of SAM-ready loudspeakers is the only shortlist of products you’ll need. Third, if you have a Devialet and loudspeakers that are not on the SAM list, start a campaign to have your speakers tested and matched (and if they are too old or obscure, think about trading up for ones on the list). Finally, if you are in the market for a complete system with bookshelf loudspeakers, the Ensemble is a hard act to beat. Put simply, Ensemble sets the benchmark against which audio should now be judged. And if you think that’s good, wait ‘til you hear what it can do with really high-performance loudspeakers!

Egglestonworks Nico loudspeaker

I have to say I was surprised when Egglestonworks announced the Nico and Emma speakers it was to unveil at CES this year. They seemed almost affordable. Not a state of affairs that one associates with the upper price brackets of the high-end, but in truth the company has been overtaken in the megabucks stakes, and all of its models are relatively affordable by the highest standards. Nico, however, is the entry point to Jim Thompson’s Memphis-based company, yet it still has the distinctive Egglestonworks style, thanks to elegantly curved flanks and a machined aluminium facia that ranks alongside the best in terms of precision and finish. I particularly like the way that the protective tristar over the tweeter is held in by three ball sockets. No one needs to go to these sort of lengths in a loudspeaker, but it’s nice when they do. The pearlescent white finish is very nice too; Nico may be small, but it’s perfectly formed.

Nico and its floorstanding sister Emma are the first models in a new range for EW. They will be joined by home cinematically (or in the US, theatrically) oriented models including a subwoofer, centre channel, and surround speakers. The first two members of this series share an EW soft dome tweeter and the same size cone drivers. Emma is specified as having a carbon cone whereas Nico is not, presumably because the former is a two and a half way, not a straightforward two-way. The woofer in Nico is a polypropylene unit to suit its mid/bass duties. Apart from size and price, this is also the first EW model to feature a front-firing port, chosen in order to make siting more flexible. There is always a trade-off with such things; front firing ports are more audible than rear ones but they allow closer-to-the-walls placement options, if desired. In Nico’s case, this even extends to a bookshelf, or so we’re told.

The cabinet is made up out of cold press laminated MDF flanks with machined MDF around the middle, the whole lot being hand finished prior to painting. Inside are two rib-like vertical braces in and one horizontal brace, which combined with the intrinsically stiff shape of the curved sides and the aluminium front baffle should make for a pretty rigid cabinet. The lack of parallel sides internally is also beneficial because it limits the potential for standing waves. The rear panel reveals a single pair of terminals which, while not as fashionable as a bi-wirable set of four, is often better from a timing and coherence point of view. It also saves having to find out which pair to connect to in a single wired set-up; inconveniently they often sound different.

 

The base of this speaker had me baffled for a little while. It doesn’t feel like wood, but something slightly softer, more like plastic. I found out it’s a branded variant of PVC called Sintra; it’s used on the base of EW’s floorstanders as well, and was chosen because it’s less likely to damage floors than wood.

The aluminium on the front baffle is not just about looks; it also reinforces this critical panel and reduces vibration induced by the drivers. It also covers up the mounting points for the mid/bass unit rather neatly and provides somewhere for the company to laser cut its name. No grille is provided with Nico, but why would you want to put a piece of cloth over drive units anyway?

Distributor Tim Chorlton recommends using heavy stands and setting them up like PMCs; fortunately, I use PMCs as a reference so I know of what he speaks. I put them on 60cm Custom Design FS104 stands with mass loading and Blu-tack for the interface with the speaker. This was a combination that seemed to work well, although later I tried some ball bearing supports from a Naim Fraim stand, which were beneficial in tightening the bottom end and improving timing. Positioning the Nico close to the rear wall and setting them up parallel to the side walls seemed to work best in my narrow/long room. Tim recommends crossing their axis a metre behind your head but I found the sound a bit ‘hot’ like that, the midband being quite forward.

Thus arranged and with the Atoll IN200 integrated amplifier, Nico produced a polished yet clear cut rendition of Yello’s ‘The Expert’ [Touch, Universal] with an appropriately large soundstage and big, relatively deep bass for the size of speaker. Further listening revealed it to be very good with voice; if a recording is good in this regard Nico will let you know all about it. Providing more power in the form of ATC’s P1 amplifier and Townshend’s Allegri controller resulted in increased low end control and credible double bass on Patricia Barber’s ‘Bye Bye Blackbird’ [Nightclub, Premonition], the word muscular seems most apt for that instrument as it underpins the full scale image that Nico is capable of. Barber’s voice could be more focused but this didn’t undermine a visceral performance that made me want to listen longer. Being a small two-way, it has decent timing skills as a matter of course, but what is less expected is the bass extension on offer and the overall transparency. This can be a little divisive about what you choose to play, however; the difference in recording quality is magnified, which is good if you have lots of great sounding albums but not so hot if your tastes run to less classy stuff. However, the timing skills make up for a lot, and I was able to enjoy early Parliament [Osmium, Invictus] with ease, while David Crosby’s latest release Croz [Blue Castle] sounds very much better (as you’d expect of the chronological gap between them). It’s plush and solid, a particularly good effort for such an ole timer.

With Herbie Hancock and Norah Jones’ rendition of ‘Court And Spark’ [River: the Joni Letters, Verve] you get all the poise of these skilful musicians in the context of a slightly blurred voice; the upper bass is not as clean as can be achieved with the very best at this price but you don’t notice it too often. ATC’s similarly sized SCM11 offers similar enclosure volume, but is about half the price and is a little more relaxed and evenly balanced. It’s important to note that the ATC speakers achieved these results with an ATC amp.

Tim Chorlton also supplied an amplifier which will be covered next month, the Rogue Audio Cronus – a push-pull KT120 valve integrated. I gave that a go with Nico. Tim knows how to match his components, that much was clear from the off; this pairing timed well and the smooth balance of the amp combines beautifully with the slightly exposed nature of the speaker’s midband. The fluent rather than hard-edged character of its bass doesn’t exacerbate the port output either and as a result of this balance I was prompted to join in with Mike McDonald in the chorus of ‘Bad Sneakers’ [Steely Dan, KatyLied, ABC]; good thing I was alone. The scale and scrumptiousness of Hancock and Turner’s rendition of ‘Edith and the Kingpin’ from River… was enhanced, albeit at the expense of the bandwidth extremes. But the heart of the music is well served; the message is clear because the emotional quotient is delivered in full effect. You can stop listening to the sound and let the music take you to a better place, a result that any good system should be able to deliver but not one that necessarily results from maximum tonal range.

 

Lorde’s ‘Royals’ [Pure Heroine, Universal] is rather more blunt, but it goes down lower than this combo will reveal. What it does let you hear is the degree and nature of the compression used to give the song its pop appeal. Martha Argerich playing Chopin Preludes [DG] is a lot more rewarding; it works because Rogue and EW have such superb fluency with piano and high sensitivity to dynamics, the lifeblood of acoustic music. Brendel’s Piano Sonatas [Philips] are even better in this regard, spritely, nimble, and rarely bettered.

Like any other loudspeaker, Nico is dependent on the choice of partnering amplifier – possibly more so than average, because the midband is so vivid that anything edgy in this area will have its limitations revealed. There are many great two-way standmounts at this price, but few which are finished to the standard seen here, and not that many which have the same balance. This is not a ‘me too’ product; it’s a speaker that will fit some systems extremely well. If you have a push-pull pentode amp, yours could be among them.

Koetsu Blue Onyx

In an age of hype, where everyone ceaselessly self-promotes to gain attention and market share, Koetsu represents an oasis of calm. Founder Yosiaki Sugano (1907 – 2002) was a man of many parts – artist, musician, swordsman, calligrapher, business executive, and father. He drew inspiration from the 17th century Japanese artist Honami Koetsu (1558-1637).

So what else but to adopt the name of his hero Koetsu when deciding to manufacture high quality MC pickup cartridges back in the late 1970s? Amazingly, the company seems never to have advertised its products, nor produced any sales leaflets. All the same, word quickly spread among audiophiles, and the Koetsu legend was born. In 2014 Koetsu still doesn’t have an official website. Twitter? Facebook? What’s that?

With Koetsu, Hearing was Believing. Once you’d experienced a Koetsu, little-else sufficed. The original models were quite large, with a rosewood body covering. Later models slimmed down a little, and featured exotic body materials, from lacquered Urushi finishes, to the use of natural gemstones including Jade and Onyx.

Sugano’s minimalist approach soon earned him mythical status in hi-fi circles. It’s said his ‘death’ was erroneously reported no less than three times – something that apparently pleased him no end! It all became part of the Sugano legend, adding to the mystique of this most unusual of brands. Finally, though, reports of his death were not greatly exaggerated, and the legend died just a couple of months short of his 95th birthday. However, the Koetsu name lives on through Sugano’s son, Fumihiko, who was trained to take over his father’s legacy, and keeps the brand clouded in mystique to this day.

Koetsu cartridges still enjoy near-mystical status; the creations of  a quiet infinitely-patient sage, steeped in ancient wisdom, slowly and painstakingly crafting transcendental products  – and all this passed down the line from father to son, master to new master. Inevitably, the legend is somewhat at odds with the reality. But still the myth lingers on, and with good reason.

 

There is a magical quality to the sound of a Koetsu – something beyond measurement and statistics. Naturally, precision engineering and using only the best materials have long been an essential part of the mix. But the end result exceeds the sum of the parts. Call it art; call it alchemy; call it BS – for those with ears, a Koetsu was (and is) special.

The Koetsu experience comes at different price points – from (relatively) affordable to ‘is that a misprint?’  Even the basic models sound excellent, but as you move up the range, the sound grows increasingly rarefied. Many Koetsu pickups feature 99.9999 purity copper wire for their coil windings with a special silver cladding that consists of a silver sheath slowly drawn over the copper conductor, but the Blue Onyx is said to be Platinum Coiled. As ever, details are sketchy – so we presume the copper is Platinum sheathed. The motor assembly employs Samarium Cobalt magnets for their concentrated power.

The cantilever is made from boron, but perfectionists with even deeper pockets can go for an optional one-piece diamond cantilever and tip. This avoids the interface between stylus tip and cantilever, and increases rigidity, albeit for an extra £3,666. People say you can’t put a price on perfection; actually, perfection costs precisely £11,066!

The body shell is fashioned from powder blue Onyx, so each cartridge has a uniquely beautiful appearance – like a piece of exotic jewellery. It’s not a small cartridge, incidentally – 23mm long and 14mm deep – and also quite heavy at 14.8g. Your chosen tonearm will benefit from a heavy counter weight. Optimum playing weight falls between 1.8g to 2g. 1.8g offers slightly greater transparency and fine detail, but 2g reduces surface ticks and improves tracking slightly. Now, we’re always told not to trust our ‘first impressions’ when evaluating hi-fi. But calm rational objectivity can be difficult once something like the Koetsu Blue Onyx begins to play…

The Blue Onyx sounds impressively sharp, yet at the same time, beautifully refined with an effortless velvety smoothness that’s almost uncanny. It’s every bit as detailed and dynamic as you could wish for, yet wonderfully poised and relaxed-sounding. In musical terms, the presentation is effortless and natural. The music seems to ‘happen’ between your loudspeakers; voices and instruments materialise before your very ears.

The timbre is somehow both mellow and sharply focused – smooth and subtly shaded, yet crisp and tactile. It’s a beguiling mix of opposites; sonorous warmth and silky smoothness, hand in glove with immediacy and crisp attack. Dynamically, the Blue Onyx ‘projects’ with an impressive sense of power. The sound is very energetic and colourful, yet unexaggerated and truthful too.

With a full and solid bottom end, liquid midband, and brilliant translucent highs, there’s much to ravish the ear. Transient detail is pin-point sharp, yet without aggressiveness, and always wonderfully homogenous. This ability to produce vivid, sharply-focussed detail without sounding ‘hard’ or over-driven is very much a Koetsu trademark.

I found the Blue Onyx musically engaging and positive-sounding, while remaining relaxed and refined. This mix of opposites is apparent on most sorts of music, particularly human voice. Whether it’s an unaccompanied solo singer, massed choral forces, or the lead vocals in a rock or pop track, the Blue Onyx delivers natural believable results.

 

Clarity is quite stunning. The way this cartridge separates individual vocal lines, and allows subtle instrumental passages to be heard, borders on the miraculous. It’s also good at recreating a sense of aural space – revealing the natural hall ambience behind individual voices or instruments.  As a result, each retains more of its identity.

Yet, for all its vividness, the Blue Onyx is surprisingly easy to listen to. It delivers a very coherent sound. Opposing contrasts – high and low, loud and soft, sharp and smooth – co-exist in perfect balance. So the end result is harmonious and cohesive, and the music unfolds in a way that gives you more time to listen – more time to unravel the individual strands that form part of the whole.

It’s the polar opposite of a sound that is aggressive and ‘forward’ – bombarding the ear with a welter of unrelated leading edges so the brain struggles to make sense of it all. The Blue Onyx is delightfully easy to listen to. It delivers a very ‘ear-friendly’ sound. Your brain has less processing to do, so it’s better able to take in the entire musical scene, and make better sense of the whole.

But please understand – the refinement of the Blue Onyx is something innate; not something false that’s grafted on to each recording regardless. It’s very much a pickup that faithfully reflects the individual qualities of each recording – an open transparent window on the music. It will sound sweet and beguiling one moment, then tack-sharp and crisp the next – often during the same track.

Clearly, the Blue Onyx is one magnificent cartridge. It’s among the finest you could ever hope to hear, with few peers when it comes to turning those squiggly grooves into living breathing music. You’ll listen to it with rapt attention – much as you’d listen to real musicians playing live in front of you. Each Blue Onyx is made to order, so there may be a long delay before you get one. But, don’t let that put you off; the wait will be worth it!

Aurender W20 music server

As I was one of the last people on Earth to buy a CD player, on purely personal musical grounds, I could never be accused of being an early adopter where new technologies are concerned. It has taken over three decades to get high-end CD players to the quality I am hearing lately, and the arrival of streaming and file storage has been playing only a bit part in my listening for the past few years, so you won’t be surprised to have found me at the back of the queue with a rather unconvinced look on my face during that time. When, somewhat in frustration that I wasn’t sharing in the euphoria, I asked respected friends in the hi-fi business in which direction the land of milk and audio honey lay. I was directed toward the Aurender W20. Wise words indeed, as I discovered when I managed to secure a loan of this remarkable device. Earlier last year I got my hands on the dCS Vivaldi, a digital playback system that for me had pushed the art forward to a new level and dCS, being the UK distributor for Aurender, clearly shares many of the same values. In a sense, this made the challenges the Aurender faced even more daunting, especially considering its premium price. Vivaldi sets the musical bar extremely high and any streaming device at this price that doesn’t compete musically with the best that CD has to offer is going to be a big disappointment.

The W20 has all the hallmarks of a high-end audio component. Build quality is as good as I have seen, being incredibly impressive inside and out, with each section of the machine located in its own ‘room’ and separated by thick aluminium walls. The front panel display is a model of clarity as it is easy enough to read from across the room, and the information is scrolled across the large screen. I cannot tell you how much I like this after a succession of micro readouts, illegible from more than a few inches, that illogically seem to adorn so much high-end audio these days. The panel can also be set to display a pair of large coloured output meters, which is rather retro, but interesting.

Internally, Aurender has gone to great lengths to reduce noise. The audio board is both mechanically isolated and powered separately by a pair of dedicated lithium iron phosphate batteries. These have automatic alternating charging cycles, which mean that neither battery is allowed to run so low that it might affect audio performance. This also eliminates any mains noise that might otherwise find its way into the audio side of things. Battery replacement? I hear you ask. Forty years at eight hours a day, every day, says Aurender.

The W20 is available in two versions, and these relate to the size of the HD’s in each. The model I had utilised two 3TB drives, though there is a version that increases this to twin 4TB drives. When you think that the smaller version can store up to 15,000 CDs, the 8TB version might be gilding the lily for most listeners.

 

I see the W20 as a computer transport, or you could call it a server. It is not a one-box solution as there is no on-board DAC, but there is the ability to clock the unit externally and I did this through the Vivaldi clock. In fact, there is a USB-RS232 dongle that is made specifically for dCS clocks with their variable output banks. The on-board clock is already extremely good, though, and is comprised of three oven-controlled crystal oscillators; but once you have heard the extra stability and strength of the W20 clocked externally through the clock-out of the quality of the dCS Vivaldi, you will almost certainly mark it as a future upgrade. Considerable work, done between the two companies, ensures complete compatibility, but whichever direction you go, a top quality DAC is absolutely mandatory to realise the W20’s formidable quality.

Digital outputs comprise a pair of AES/EBU XLR sockets that can be used singly or in dual mode, S/PDIF (in either BNC and RCA form), or USB that will support DoP (DSD over PCM). Which connection you choose is going to depend on your system and cabling. Personally, I much prefer the dual AES method, which I am told is the first time this has been offered on a music server. However, all are extremely good, each showing subtle differences that are easily distinguishable. Another reason for taking advantage of the dual AES cabling option is that some higher end D/A converters need this connection method to support sample rates over 96 kHz. The W20 also has a completely separate audio board, and the internal ‘room’ for this is, as you might expect, of the very highest quality.

Getting musical files onto the Aurender is usually a simple job, one best done on a computer by using drag and drop methods, although I also ripped quite a few CDs onto it by using a simple and inexpensive Samsung disc reader. Obviously this will only copy in 16 bit 44.1kHz, but you can load the Aurender with files of any digital resolution from your computer.

The W20 came with close to 800 albums pre-loaded and I ripped a lot more on through the disc reader during my time with it. Just hook it into your router for access to the metadata and control of the machine. All you need then is an iPad for the Aurender app that is such a critical part of the machine’s function. There is no separate remote control, just the app, but it allows you to take a look at everything, and through it you will be automatically informed as and when updates are available. It is also here that the beauty of the machine’s usability can be made or broken. You can control and monitor all the W20’s working parameters, such as monitoring the individual drives, adjusting the time needed by the DAC to adjust to new sample rates, set for fade in/fade out, enable the dual AES/EBU outputs, etc.

 

There are different types of sort features, but I preferred the ‘by album’ setting where I could scroll through the covers, selecting the odd track here and there. If I wanted to make a playlist though, the more music you install, the more you may want to change this feature to a compact list, especially for browsing. You can search alphabetically by artist or album, but bear in mind that you could have 15,000 covers or more on the W20’s list. You can sort by genre or even resolution and dCS, who supplied the W20, had pre-loaded the machine with plenty of standard and hi-def music files adjacent to each other, so I could compare a standard resolution with the DSD version instantly, if I was so inclined. It brings into sharp focus just how absolutely vital the format of the app itself is. With such a comprehensive machine able to store so many files at so many different resolutions, it would have been so easy to make the interface rather annoying and over-complex, but after a period of adjustment you can get where you want to be quickly and playlists too are very intuitive to assemble and name. The only thing I would criticise is the alpha list to the right of the window that enables you to quickly locate an album or artist depending on how you have preconfigured the search parameters. In lower light levels, I think the letters should be quite a bit bigger and certainly much brighter (or perhaps a different colour) to make them easier to see and access.

Once the Aurender is in use, the storage HDs go to sleep after the files have been moved to the 240GB SSD, and there are no moving parts to add noise or vibration during the playback process. It is incredibly quiet mechanically and sonically, with black backdrops to any music you chose. You can listen for anything that might indicate you are streaming from stored files but I doubt you will find it. The Aurender just runs with the program. Playlists are rolled out smoothly with only the occasional light click from the machine if a sample-rate change is called for and the transition from track to track across different albums is remarkably smooth. Overall I would have to say that sound quality is incredibly good and quite easily the best I have heard with streamed music.

There is virtually no detectable loss of bandwidth and the rhythmic flow of the music is superb, especially considering that I had the Vivaldi transport sitting next to the W20 for quick comparison. The Aurender is full-bodied, weighty, and fast, with almost equal resolution to the transport. I say ‘almost’ because I still find that the straight CD playback, within this system, shows more depth and transparency. But I should reiterate here that there are very, very few source components that can go toe to toe with a clocked Vivaldi system. Personally, I haven’t heard any, but the caveat here indicates that there is an increasing amount of equipment out there that I haven’t used at home yet.

The W20 doesn’t soften bass or render it less pitch accurate, and it maintains impressive focus from top to bottom. Higher resolution files can sound sound thrilling –full of micro detail, very precise tempo wise, and possessed of a quality of dynamic ‘life’ that I have found missing from lesser streaming systems. The 24-bit/96khz version of Herbie Hancock’s The Joni Letters [Verve] was absolutely stunning. The increased resolution changed the character of the piano much more than I was expecting. This hi-def version really lived up to its billing here and doesn’t suffer from what Alan Sircom described as “The numbers game”. The standard version in comparison emphasises the hammer and has a slightly less tonally pure and colourful harmonic character where the hi-def certainly has more space, grace, and stability about the way the piano sustains through chords to the decay. One of my favourite tracks, ‘Solitude’, just sounds so inward and contemplative and, I have to say, more expressive on the Aurender through the Vivaldi DAC than when the DAC is fed directly from the CD. The spaces and intervals are more relaxed and this of course brings the phrasing into much sharper focus. Great musicians employ the blackness and treat it with respect. ‘Solitude’ is absolutely reliant on the sense of colour, ease, and reflective expression within that quiet, expansive place. It works magnificently.

 

The Aurender does not have any sense of being musically mechanical either. Of all the streamers I have heard, there has so often been that feeling that the music was being squeezed out through a clocked buffer, and that the flow was somehow inhibited and rather unnatural. But, in my experience, the Aurender sets a new standard here, and I think this must bode really well for the future of file-storage as long as this degree of musical excellence is maintained. But, I was more than impressed with some of the standard resolution from old recordings that I last heard on vinyl back in the 80’s and in this way the W20 shares a certain new regenerative and sparkling focus with the Vivaldi. King Crimson’s Larks Tongues In Aspic [Discipline] was an album that I knew well when I used to worship at the alter of Robert Fripp and his excruciatingly physical ‘guitar mechanics’ approach. Yes, Robert could be extremely metronomic and had a way with repetitive phrasing through arpeggios that transfixed me back then, but he was also capable of the most beautifully lyrical moments. The Aurender just wrings every drop of music from this ripped disc, and I am amazed how fresh and colourful it sounds. In a sense, it brings everything the W20 absolutely excels at into sharp focus. Is it as good as the Vivaldi transport? Almost, but look toward low-level detail and the way in which the dCS can discriminate threads and instrumental mutterings for the answer to that one, especially at low frequencies where the Vivaldi is so very, very articulate.

The Aurender W20 is a technologically superb piece of electronics and is quite easily the best of its kind that I have heard, although new models from many manufacturers are coming thick and fast now. Despite this, its real value to me lies in the way it plays music without so many of the irritating issues I have noted before. Aurender has clearly gone to great lengths to ensure that nothing gets in the way of its most important purpose. It fulfils the role of a single or second source brilliantly without actually playing second fiddle to anything. It is a truly exceptional product. Expensive but very highly recommended.
