RME Launch ADI-2 FS at IBC 2018

London Colney, UK – RME have chosen IBC 2018 to unveil the new RME ADI-2 FS, the latest addition to their range of professional AD/DA converters.

A compact and flexible 2-channel AD/DA and format converter, the ADI-2 FS offers high-end analogue audio conversion to and from SPDIF, AES and ADAT, at sample rates up to 192 kHz. The three digital connections provide compatibility with a wide range of professional and consumer audio devices, with options for both SPDIF/ADAT optical I/O, and SPDIF/ AES-EBU coaxial I/O.

RME ADI-2 Series Converters

The newest member of RME’s high-end ADI-2 Series family, the ADI-2 FS shares many similarities with its critically acclaimed siblings, the RME ADI-2 Pro FS and RME ADI-2 DAC. The two servo-balanced XLR/TRS analogue inputs use the same advanced circuit design of the award-winning ADI-2 Pro, providing an extended frequency response and offering outstanding low levels of noise and distortion. 

The ADI-2 FS also uses the conversion technology of the ADI-2 Pro: the AK557x family and the AK4490 converter chips not only offer 192 kHz sampling frequency and extremely low distortion, but also a dynamic range of 120 dBA.

Alongside the pristine sound quality, the ADI-2 FS also offers a range of digital format conversion options. The coaxial RCA SPDIF I/O has a switchable Channel Status to make it fully AES/EBU compatible (cable adapter required). Additionally, the optical TOSLINK I/O can handle up to 192 kHz and also serve as ADAT I/O (even at 192 kHz). Outputting incoming SPDIF signals as ADAT (and vice versa) is also supported, in both AD/DA and D-D mode.

 

Front Panel Control

The ADI-2 FS features a logical and informative front-panel, with clear and distinctive labelling and informative status displays. A 6 LED level meter also provides input level information at a glance, making the RME ADI-2 FS extremely simple to operate straight out of the box.

The RME ADI-2 FS is due to ship December 2018.

The RME ADI-2 FS will be on show at IBC 2018 in Amsterdam at the RME booth 8.D70 (14th – 18th September 2018).

RIVA Festival wireless loudspeaker

Riva has had a phenomenal success rate. In a remarkably short time, the company has had hit after hit, first with its highly portable Turbo models (we tested the Turbo X in Issue 133) and now with its models in the WAND system, such as the Arena (which we also tested, in Issue 151). The Festival is the company’s biggest model to date. It’s also the first that doesn’t support a battery, either built-in as standard or as an add-on option.

Like the Arena before it, the Festival is part of Riva’s WAND system, although the subwoofer suggested to accompany both products never materialised. The only option for the Festival now is a pedestal stand. Not that it’s necessary; the Riva Festival is a large loudspeaker perfectly designed for non-audiophile set-ups on tabletops and furniture. Its wide, curved style and top panel controls don’t lend themselves to sitting on a pedestal (it looks top-heavy). However, unlike many of its contemporaries, it has passive radiators firing to the rear (the drive units ‘proper’ fire to the front and sides of the speaker). This means it is best used slightly away from the wall and free from side-wall distractions and interactions. It’s not a free-space design, however, and can benefit from some boundary reinforcement. The installation process does not include any room correction or adjustment.

Like the other models from the brand, the Festival uses Riva’s patented Trillium DSP system to create a stereo sound from a single loudspeaker. And, like the Arena, the Festival can play music files of support up to 24bit, 192kHz resolution. Festival has an inbuilt Chromecast device and an ‘away’ mode, allowing a multiple network of loudspeakers without an available Wi-Fi network.

Chromecast also allows you to access the WAND devices through a range of different options. If you have a smartphone, through one of about a dozen apps. If you have an Android phone, make that about two dozen apps. But the concept is the same; download Google Home and Riva’s WAND apps, connect the speaker to your Wi-Fi network using Google Home apps, the Festival will automatically update its software (should it need to), and then either ‘cast’ music to the speaker, or use AirPlay, or Spotify Connect to create your musical library. You can’t connect the Festival to a home music network unless you route that music through a Chromecast compatible app. I’d go further; don’t even think about using the Festival unless you are willing to join one of the compatible music provider services: Spotify. Riva recommends an initial three-hour run in before playing music at higher volumes, and this is probably a good idea. Not that the sound will necessarily improve over the three hours, but it means if anything shakes loose, it’s likely to do that in those first few hours, and it’s best to do that at sub-cone-frying levels.

 

Unlike our test of the Arena, we actively asked for a pair of Festivals. We used a pair of these for two simple reasons. We wanted to see how well they group and how well they work in a multi-zone capacity. The simple answer is ‘stupidly easily’. OK, no matter how idiot-proof a thing is, the world has a remarkable way of making a better-quality idiot, but you’d have to actively hit the Festival with sticks to unhinge it here. Use Google Home to name your speakers (‘Lounge’ or ‘Kitchen’ is better than ‘Barry,’ ‘Mr Frisky,’ or even ‘Cthulhu’), then group them in the same app. You can also change their basic profile, to ‘Power Mode’ for bigger rooms’ or as dedicated left and right channel loudspeakers.

The clever – make that extremely clever – trick here are the options it keeps open. Buying two of them isn’t just designed to make a more extended stereo but is ideal for filling either a house or a large room with sound. And the seamless part of that really is brilliant. You can walk from loudspeaker to loudspeaker with no changes in phase or delay. Nothing. Nada. If I was ‘speccing’ a sound system for a bar or a restaurant, that was designed to be driven wirelessly through the Google Home app, this would be a fine option. You can even unhook one from your Wi-Fi system and use it as its local WAND network. Unlike the smaller model, there is no battery component and so Summer time beach fun is beyond the Festival unless your beach comes with plug sockets or a generator, but as a transportable audio device, the Festival is always minutes away from a party if there is mains power around. And Festival’s latest upgrade makes that party so much more hearty.

With the rise of Google Assistant, you can now talk to your phone and tell it what music to play, and it will automatically route that music to the Festival. For Apple die-hards, abandoning Siri for Google Assistant is like being unfaithful, but even they might conclude that their need for Apple opprobrium should be set aside in this case. Yes, if you use it for every track you play, people around you are going to get fed up with your constant “OK Google…” comments, and it is prone to being hijacked by someone determined to play back-to-back Captain and Tennille songs, but let’s not mess around here. You can talk to Spotify through your phone and get it to play the music you want, and then play it on the Festival. That’s almost magic.

If the technology is starry-eyed, then so is the sound in context. Like many products in this issue, we need to be distanced between what is possible as opposed to what is physically possible given the nature of the device. That in some respects shapes the sound and the type of music you will play through this kind of system. Normally, that would be the audiophile death knell, but the words ‘lighten up’ start pulsing here. You are never going to play some happy hardcore or tropical house or some ironic K-Pop through a pair of traditional loudspeakers, and you will never play ‘Keith Don’t Go’ through the Festivals. We’re quits.

The sound, however, does not need to apologise for itself in context, as it makes a very decent, extremely fun sound. It’s not the last word in deep bass or midband clarity, especially when comparing this to a full-range audiophile loudspeaker. On the other hand, trying to extract this kind of wide-ranging performance from a conventional set of loudspeakers would be functionally impossible at the price. Speaking of stereo, the two speakers used in stereo mode work well. The wide stereo-from-every-driver Trillium concept does make a single speaker sound like a stereo pair but using a pair of Festivals in stereo doesn’t quite gel in the same way. It’s as if they try too hard to deliver stereo and instead create a huge but diffuse sound. Some may like this, but it lacks the cohesiveness of more mainstream speakers. Two speakers are more than justified, however, because they have more than just stereo to offer, and their ability to play time-coherent sound around a room without delay or phase issues is truly remarkable.

 

Riva faces some very stiff competition (some of it in this issue) but the 500lb gorilla in the room is how it works compared to Sonos:Play models. In terms of functionality and app-support, Sonos wins hands down (but it wins hands down against almost any audio brand). Musically, however, five seconds with the Festival and the Sonos gets put away. There is so much more expression, dynamics, and clarity to the Festival! Whether that’s enough to win over those tens of thousands of Sonos users, or converts a slew of prospective Sonos buyers, only time (and Sonos’ massive advertising budget) will tell.

These are deceptively clever loudspeaker boxes. There’s so much the Riva Festival can deliver alongside really good music, that it might surprise you just how a small loudspeaker with buttons on the top can make a sound that big. Now that you can talk to the Festival via Google, the Festival has the potential to become the go-to speaker choice for all manner of listeners disenfranchised by technolgy. Yes, you need to know how to access Google Home from your phone, but on the other hand, who cares? When Festival rocks, it really rocks!

PSB M4U 8 wireless noise-cancelling headphones

In 2012 the famous loudspeaker designer Paul Barton, founder of PSB Speakers, launched his first ever headphone, called the PSB M4U 2, priced at $400. The M4U 2 was versatile with a capital ‘V’, so that it offered three operating modes: a very good sounding passive mode, an even better sounding active mode, and an effective, musically sensitive noise cancelling mode. No matter what one needed or wanted a headphone to do, the M4U 2 seemed ready to fit the bill with no questions asked.

When I reviewed the M4U 2 headphone for Playbackmagazine I called it a “headphone for all seasons” and observed that it was “one of the most cleverly conceived, well executed, versatile headphones that $400 can possibly buy.” Understandably, the M4U 2 sold like free Guinness on St. Patrick’s day and went on to become a great commercial success. Even so, time waits neither for man nor for classic personal audio products so that in 2018 PSB decided it was time to launch a successor to the M4U 2, the wireless Bluetooth-enabled, noise-cancelling M4U 8.

At first glance, the temptation is to look at the M4U 8 and think, “Oh, it’s basically a Bluetooth-enabled version of the original M4U 2.” In a sense that synopsis is partly right, but if you look deeper you’ll discover there’s more to the story than at first meets the eye. To understand what I mean by this, it helps to survey carefully the differences between the models.

The original M4U 2 was a high quality passive/active/active+noise-cancelling headphone driven by a switch selectable, onboard, battery-powered amplifier and that featured an effective, switch selectable, and music-minded analogue noise cancellation circuit. We felt—as did many listeners—that the M4U 2 sounded best with its active mode engaged, but with noise cancellation switched off. This was because the M4U 2’s noise cancellation circuit, though quite good, involved some audible tradeoffs between noise reduction effectiveness and overall musical transparency.

The M4U 2 also offered voicing that introduced what Barton then termed “in-room feel” (and now calls RoomFeel, used as a marketing descriptor); that is, headphone voicing that mimicked the sound of a comparatively neutral loudspeaker as heard in a listening space offering an average amount of ‘room gain’. In many respects, this voicing strategy was and still is the secret to the success of Barton’s headphones; when you put PSB headphones on they immediately sound much the way you wish your loudspeakers could. In sum, the M4U 2 was a good passive headphone, an even better active headphone, and a very good noise canceller that, while perhaps not the last word in noise reduction, did relatively little harm to the music at hand.

On paper the M4U 8 initially seems similar to the M4U 2; it is roughly the same size, weight, and price; it uses similarly sized dynamic drivers and a similar though not identical frame design; and it provides similar operating modes (a passive mode, an active mode with RoomFeel™, and an active noise cancelling mode with RoomFeel™). The most obvious difference involves the M4U 8’s addition of Qualcomm-based aptX HD Bluetooth connectivity functions, which PSB characterises as “the high fidelity version of Bluetooth”. In addition to wireless modes of operation, the M4U 8 also provides two wired modes of operation via a 3.5mm wired connection, or via “USB from the computer, which recharges the batteries for wireless operation.” The M4U 8 comes with built-in rechargeable batteries, whereas the M4U 2 used conventional user-replaceable alkaline batteries.

As you look closer, though, other significant differences begin to appear—many of them having to do with recent advancements in digital signal processing. When used in active mode, for example, the M4U 8 applies DSP to implement the most transparent sounding and highest resolution version of RoomFeel™ voicing to date. The upshot is that, when powered up, the M4U 8 sounds markedly more open, transparent, focused, and expressive than the original M4U 2 did.

 

In turn, the M4U 8’s noise-cancellation functions come courtesy of a powerful new noise-cancellation device sourced from the Austrian firm AMS—a device that enables the headphone to maintain very nearly the same wide-open and transparent sound, even when its noise cancellation circuit is switched on (something that could not have been said of the original M4U 2). In fact, you could even build a case to say that the M4U 8 actually sounds best with noise cancellation enabled, since you will enjoy the same basic sound quality as when active mode alone is engaged, but with a markedly lower noise floor.

The noise cancellation system uses four microphones, whereas most competitors use only two. There is also a pushbutton selectable ‘Transparency Mode’ that allows users temporarily to reduce playback levels by 30dB so as to listen in to sounds from the outside world. Mics and control switches also allow users to answer calls from connected phones or to adjust basic playback functions on connected portable devices—all via Bluetooth.

Ergonomics were always a strong suite of the M4U 2 and the same is true of the M4U 8, although the new model looks more finely finished thanks to matt black soft feel ear cup yokes, so called ‘gyro-suspended’ ear cup finished in satin black, and a pleather-covered headband and ear pads. Overall, the M4U 8’s offers a more tasteful, upscale look and feel vis-à-vis the gloss black plastic parts found on the original M4U 2. Both ear cups provide 3.5mm signal cable jacks, meaning users can make wired connections from whichever side is most convenient. The right hand ear cup also provides a mini-USB connection port (for charging and digital audio), and four easy-to-identify controls: a track forward/backward/play/pause/call-answer switch, a three position off/on/on with ANC switch, a volume up/down/‘Transparent Mode’ switch, and a Bluetooth pairing switch.

Used in passive mode, the M4U 8 sounds good but not great, in that its mids, upper mids, and highs sound somewhat recessed and softly focused. Once powered up, however, the M4U 8 becomes a sonic treat thanks to its fundamentally neutral yet also lively and highly articulate sound, which offers what many will regard as a just-right amount of bass lift (enough to give the headphone low-end authority, articulacy, and gravitas, but not so much as to sound boomy or overbearing). The more nuanced the recordings you choose the better the M4U 8 will sound. A track that nicely illustrates this point is the Persuasion’s a cappellarendition of U2’s ‘Angel of Harlem’ from The Persuasions Sing U2[Chesky, 24/96]. The M4U 8’s do a highly effective job of delineating the individual voices that comprise the vocal quartet, while showing how the group members modulate vocal textures, timbres, and especially dynamics—often in perfect unison—to create their distinctively soulful take on U2’s classic song. The bass voice in particular sounds rich and resonant with an ideal amount of depth and weight, so that it serves as an anchor for the other quartet members’ higher pitched voices. This is where RoomFeel™ voicing shows its merits.

Another track that shows the overall balance and expressiveness of the M4U 8 is Lou Reed’s classic ‘Walk on the Wide Side’ from Transformer[RCA, 24/96]. The song opens with an unforgettable loping acoustic bass line, a gently strummed guitar, and Reed’s captivating and inimitable storyteller’s voice, and the M4U 8 gives each of these elements its due—each in perfect balanced proportion to the others.

 

Are there caveats? I can think of two, though they are very minor in the grand scheme of things. First, I would like to see the M4U 8 have slightly larger openings in its ear pads. Granted, the pad openings are subtly bevelled to allow more room for your ears on their inner sides, but even so I found my ears sometimes felt a bit cramped during multi-hour listening sessions. Second, purists might argue that the M4U 8, though expressive enough in its own right, is not quite as revealing or resolving as today’s best mid-priced planar magnetic designs. While this is true, it is important to remember that the versatile M4U 8 successfully addresses far more varied real-world listening applications than any passive, open-back planar magnetic headphone of which we are aware.

PSB’s M4U 8 is a brilliant mid-priced headphone that fulfills many different roles and meets a wide range of requirements in a hugely successful way. For people looking to begin their exploration of high performance headphones without breaking the bank, the M4U 8 is not only a great place to start, but also a fine sonic destination in its own right. That’s a claim few ‘noise cancellers’ can make.

dCS Rossini – MQA updates

This is the review I was beginning to wonder if I would ever write. Back in 2015 Alan Sircom  wrote a very comprehensive take on the then-new dCS Rossini CD/DAC and clock with the thought that I could follow it up with a user experience piece some time later. Now, much later than we originally anticipated, here it is. Since Alan’s review it became clear that the Rossini, as a full blown streamer in its own right, would be looking at future software/format updates to add to its already superb musical qualities. Exciting things were beginning to happen in the world of streaming and Roon has since arrived. As the subscription service Tidal has grown in quality and high-def downloads and MQA have been coming of age, the Rossini has been looking like a different proposition altogether. Initially and from outside dCS, it looked like it might be a scaled-down Vivaldi that had inherited some trickle-down of the top model’s DNA. The Vivaldi I believe could well be thought of as the greatest CD player that was ever made, when the history of the silver disc is written. But its price, especially for the full-blown four-box extravaganza, is prohibitive. Rossini, especially with its clock is no bargain basement device either for, but, as streaming has accelerated its own development and sound quality exponentially, it is beginning to look like a much more comprehensive proposition. Considered alongside the aforementioned Roon/Tidal axis, its appeal has grown. Especially when you consider the fact that exciting upgrades are being developed by dCS itself and that these will become available to their customers as free downloads then the whole idea of a future-proof, high-end digital music machine becomes a serious reality.

The usual prescribed upgrade path of changing hardware simply doesn’t apply within this digital framework now. Rossini is currently on its third major software update as work on the streaming side has now incorporated the inclusion of MQA encoded material and there are always tweaks to the company’s remarkable Ring DAC, a technology initially developed by the company many years ago. One of the things about this DAC architecture is its uniqueness and the company have the engineers who are constantly looking at ways of improving the sound quality. It’s one of the bonuses of in-house development as opposed to off-the-shelf DACs. These software updates are no small things either. The sonic improvements that the mapping and filter enhancements brought to the Vivaldi a couple of years ago were nothing short of remarkable and increased the potential of that great machine considerably. When you buy a dCS, you’re buying into an ongoing commitment to improved sound quality and this hopefully goes some way towards softening the blow of the initial financial outlay.

DCS has been a development partner in MQA and the latest software updates have bought the decoding of these files on board. This enhances still further the Rossini’s formidable number-crunching abilities. Alan’s review considered it primarily as a high-end CD player with excellent streaming possibilities, but like most of us, he found that, at that time, the quality of the streamed material and rips played a definite second string role to the CD side of things. The balance has changed now though and the rise in quality available from Tidal has grown surprisingly to the extent that I think it now sounds extremely good, especially as part of a system that incorporates Roon as its traffic cop.

 

The Rossini is emphatically a dCS product. It is beautifully constructed inside and out with a simple elegance to its design. It sports the full range of AES/EBU connections, balanced and single-ended outs, USB and Ethernet inputs and of course clock connections. There is also an excellent analogue volume control for those who might want to forgo a system preamplifier and operate directly into a power amplifier. The machine can be controlled by a comprehensive app while the latest dCS remote control is entirely logical and fit for purpose in a way that the previous hunk of metal never really managed. It is the first dCS player not to include SACD due to the shenanigans of the Esoteric brand and its supply to those who incorporated it. But dCS, having sniffed danger from afar, availed itself of sufficient stock to cover all eventualities. The Rossini utilises a Stream Unlimited drive and as a standalone CD player it is, in my experience, second only to the Vivaldi. But it has many more strings to its bow and is available with and without the drive itself which leaves potential customers with a large CD library with a stark choice. Do I buy the CD version or might I perhaps rip my entire collection onto a NAS drive and go with the DAC? Up until relatively recently, this was not a relevant question as comparing ripped files to the disc would in the vast majority of cases, bring a thumbs up for the disc, but not any longer though. If you heard streaming and files ripped onto NAS drive a few years ago you will, like me, be astounded at how much better the whole technology has become.

So what does a Rossini high-end streaming and NAS based system actually look like? The simplest way to explain is probably to run through my domestic set-up and the solutions to everyday situations that I was presented with when the system was installed. It would have been nice if the router was next to the audio side of things, but it wasn’t so I needed a decent cable – an Audioquest in this case – that runs to the system and straight into a five-way ethernet switch. This small (and cheap) device becomes the switching hub into which I have plugged a NAS, the Nucleus that runs the Roon software and the Rossini. There are no USB connections into the DAC as it’s all done via its ethernet input. That’s about it and it is a very compact yet powerful interface that has proved itself remarkably stable and glitch-free since the Nucleus took over the Roon processing responsibilities from my MacBook.

There is something very special about the way the Rossini deals with digitally stored and streamed files. It is a full blown digital system hub in itself. It doesn’t need a separate Upsampler or the dCS Bridge to open the world of Tidal, or other subscription-based music software. It is all done internally. The unfolding and decoding as well as the conversion is achieved within the Rossini and this is a very good thing indeed. Files from a NAS drive also sound very good and the high res files, in my opinion, are the best of all. Ripped files are more impressive than I have ever heard before and I have been dipping my toe in and out of this particular pool for years. So, unless you have a very high quality CD replay system I would suggest that ripping your CD collection will bring superior results but would also strongly suggest you try and get hold of some of the higher res files that are becoming more obtainable these days. I have been staggered at a 192kHz / 24bit Pet Sounds[Capitol] as well as a copy of Bill Evans’ Waltz For Debby[Riverside/OJC] at the same resolution. I don’t know how many times I have heard different versions of the Beach Boys’ famous old album over the years. I thought I knew it but the new file has allowed me to understand the whole thing much better. All the vocals and instrumentation are so vastly different from what I assumed from listening to the original vinyl and subsequent CD’s, even the re-released, re-mastered marketing nonsense that has provided the record companies so much extra revenue over the years are sterile, flat and rather crude in comparison. The aged quaint and thin sound is all but gone and the vocal harmonies are a revelation. The Bill Evans file merely enforces what a wonderfully tasteful and expressive player he was. Nothing superfluous, just the language of music, now heard with a greater range of tonal colours and extraordinarily beautiful dynamic pushes and sustain than I have ever enjoyed it with before, except perhaps on a very high-end record player some years ago.

 

You can now stream MQA through Tidal Masters. I was supplied with enough MQA encoded music to be very impressed, but I was also running a separate portable HD crammed full of hi-def files too and if you are looking for the ultimate in streaming quality, then both these and MQA are the future, alongside whatever new formats might come along later. MQA certainly brings a cleaner presence and sense of reality but its main lure for me is the generous increase in colour and enriched tonality. It is more precise too and deals with silences much better. Heard with all the latest dCS software updates it has that rare combination of extreme detail and musical and rhythmic integrity and this runs through listening sessions. It strikes a very attractive balance between dynamic articulation and a real sense of instrumental and vocal warmth, presence, and shading. The way it copes with high-stress musical passages where the soundstage is crammed full of musical happenings is quite easily the best I have heard from any equipment with a digital source.

The Rossini handles the increased resolution of MQA and high-res material just as it does with standard resolution files. Any digital product that you can hook into the Rossini through any of its myriad of inputs will sound about as good as it gets. When my wife questioned me as to what the clock did, she asked if it told the time, which was an interesting question. Its inclusion certainly brings a more solid sense of timing which is to be expected from the addition of a separate clock of such accuracy. But, like all dCS boxes, its effects are firmly focussed on the power and presence of the music. There’s a further increase in articulation and dynamic swings that the single-box can’t quite manage. CD or streaming based material simply comes alive and this means more expression, especially way down into the background of the mix, that lets you look deeper and deeper into the music. It is more focussed and certainly more nuanced. I guarantee that, if you hear it you will want it. You can always add it at a later date.

I said, at the beginning of this piece, that I had wondered if I would ever be able to write it. I had grown weary of people citing streamed or ripped music as being a serious alternative to listening to CD. Some of the sounds I was hearing bellowing and screeching out of the speakers over the past few years were excruciatingly bad. Was it me? I had thought, “What are these people talking about?” Progress seemed to be slow but, over the past year or so, something happened. Tidal jumped from strength to strength and with the arrival of Roon and their resultant axis, a new dawn broke for me. I still firmly believe that the music should always transcend the format but I reckon we are at the beginning of a new age of high-end quality music in the home and the good thing is that it can only get even better. Indeed, it has got better during my few months with the Rossini. There is a lot of equipment out there that can take advantage of this and the dCS machines, from what I have heard, are right at the cutting edge. The Rossini, with or without the clock, is certainly expensive, but it provides the perfect gateway in the world of music and it has no built-in redundancy as the software improvements will no doubt keep coming as and when they are needed. With or without CD transport is up to you and the sales show about a 50/50 split at the moment I am told. But I am giving serious consideration to ripping my entire CD collection to a NAS, whether this will be physically inside or outside the Roon Nucleus is yet to be decided so I doubt I will be buying many CDs from now on. These are truly exciting times for those who need access to high quality music at home.

 

The revolution has been going on for sometime now; it’s just that it has taken a while for it to have anything really relevant to say. It does now.

Focal Kanta No. 2 and Naim Audio Uniti Nova system

Synergy – when a system works in harmony to produce a sound that is as good or better than the sum of its parts – is not guaranteed. Even when two companies work under the same umbrella, that synergy is often hard-won. Such is the case here, with the Naim Audio Uniti Nova and the Focal Kanta No.2. This is a system that comes together extremely well, and while that is fully understandable, it wasn’t always the case.

There has been something of a meeting of like minds between Focal and Naim since the well-publicised Entente Cordiale between the two companies. But after the two joined forces, things were not automatically rosy from a sonic perspective: while there were Naim and Focal partnerships that worked together well, there were exceptions; Focal’s Utopia Grande EM flagship was a loudspeaker in search of a Naim amp partner until The Statement came along.

That has all changed recently, and both the Naim Audio Uniti Nova (tested in issue 153) from the refreshed Uniti line and the Focal Kanta No.2 (out of a range of one so far, tested in issue 155) are examples of that closer working relationship (or at least, Naim doing its listening tests on Focal loudspeakers, and vice versa). They are also interesting inclusions because both eschew the traditional in design terms. OK, so the Uniti Nova is still very much a black box, but the Naim following are extraordinarily traditional and the move away from green logos and matching text (as per the previous SuperUniti, the Nova’s spiritual antecedent) is the kind of thing riots are made of in Naim world. That being said, the reaction to both Nova and Kanta has been – on the whole – very positive.

Now its well-publicised supply issues are mostly behind it, the Naim Uniti Nova is settling in nicely at the top of the Uniti range, a trio of one-box streaming amplifiers with the distinctive top-mounted large volume control and clear acrylic base plate (first seen on the Statement and the Muso) range and a full colour display screen that’s a joy to read.

The Nova and the rest of the new Uniti amplifiers were the result of a four-and-a-half-year project to revise and improve upon the original Uniti platform. Given that previous platform had eight years of front-line use, it’s clear Naim could not afford to mess this up, as it would be around for years. However, it’s worth bearing in mind that high-resolution to the original Uniti was 16‑bit, 48kHz and (if you could get them) 24‑bit, 96kHz PCM files and streaming was what you did with a bad head-cold. More importantly, the original Uniti existed in a pre-iPad world, and although it ported well to that environment, the new digital platform was designed from the outset to live a world of apps. Everything is effectively powered through the app, whether it be a firmware update or complete multiroom access (see box), the Uniti Nova and its kin are made for apps. This could only happen if Naim went right back to basics with the Nova, using what went before as a loose guideline rather than a strict rule-book on how to make a 21st Century integrated device.

 

That clean-sheet design didn’t just mean the inclusion of new (and welcome) formats into the Naim fold, including Apple AirPlay and Google Chromecast, and it didn’t just mean improved Wi-Fi connectivity, or writing a bit of code to augment the digital filtration of a particular DAC; it meant writing their own unique digital filter. Naim’s Salisbury HQ has a very high boffin count, so custom DSP is entirely do-able.

Nova, however, doesn’t simply tear up the old rulebook; it borrows from that book what best suits the modern listener. For example, its built-in 80W Class AB amplifier is very much in line with Naim’s traditional power amplifier design, but the platform’s front-end is a radical departure because it operates in the digital domain, converting the two analogue inputs into the digital domain, and digitising the preamp outputs. This was probably the most controversial change in the whole Uniti project, as some of Naim’s more ‘trad’ followers objected to the digitisation process on principle. In fairness, though, most just use the Uniti Nova as the sole music device in the room.

Moving across to the Focal Kanta, the loudspeaker occupies a place between and draws technology from the Sopra and the Electra series. Coming in at a height of 1,118mm and weighing in at 35kg the Kanta N°2’s is a fairly compact floor standing dimension. But people might not see that; instead, they are most likely to view the range of colour schemes Focal went for with its latest three-way offering. Thes include four high gloss colour options with a high gloss black shell including Carrara White, Gauloise Blue, Black Lacquer, and Solar Yellow and four Matt Finish colour options with the Walnut wood finish shell in Ivory, Warm Taupe, Gauloise Blue, and Dark Grey– all of which complement the subtle tan/white shades of the flax drivers. Magnetic grilles are included but best avoided for optimum sound.

There is a clear resemblance to Focal’s higher end lines. The bend near the top to facilitate the Focal Focus Time alignment, while not adjustable like the Utopia line was similar to the Sopra’s. The new IAL3 tweeter is similar to the Sopra’s IAL2 utilising the same principles of Infinite Acoustic Loading and Infinite Horn Loading, which according to Focal research “helps with the absorption of waves, thus lowering the tweeter frequency.” Focal’s stated goal is to reduce distortion in every way possible and their continuing research toward this end has, in their view, moved one more step forward with the new IAL3 tweeter.

The Kanta N°2’s Zamac base offers a very firm support while not taking up too much space. Each of the four feet has an adjustable spike that offers options both for anchoring the feet to the floor and for levelling the cabinets. There is also front/back adjustment via the feet to refine and to level the angle of the IAL3 tweeters.

The choice of ancillary is important here, but mostly on the Naim side. If you are streaming from a local network, it’s a relatively easy decision, because Naim’s Uniti Core server is tailor-made for the task, and the combination of Uniti products, Tidal, and Roon are hard to ignore (even though Roon and the Uniti Core have a habit of rescanning Naim’s music library a lot), but Naim’s own app works well for Tidal and the Core’s library. I’d say if you can go for Roon, go for Roon (if only for its musical eye-opening powers), but Naim’s own app is no slouch. Naim makes the cable decision for you (it makes its own) and Super Lumina was used throughout.

 

Of all the systems tested in this issue, this was the most predictable. When the Kantas were first launched, a few UK journalists were given a sneak peak, and they were being played through a larger Naim separates system. That worked extremely well, and people at that event already began to speculate how the the Kanta would fare next to the then hard-to-get Uniti Nova. And the combination deserved that speculation, because it performs in exactly the way we all expected it to. This isn’t expectation bias, and it isn’t boring conformity… it’s that these two devices are exceptionally well made and fit well with one another.

The new Uniti models were a sonic change in tone compared to the predecessors. Not on a massive scale, but there has been a distinct progression from the more rounded, but fun sound of early Naim to the brighter, more detailed, and upbeat sound of this latest iteration. In fact, I don’t mind that progression, because the old Naim sound is arguably out of step with modern audio, a lot of modern recordings and mixes, and most modern loudspeakers.

Both products have a common presentation of making a good, fast, and dynamic midrange, and moving out from there. This makes the pairing exceptionally good with vocals. I played ‘Personal Jesus’ from American IV: The Man Comes Aroundby Jonny Cash [American Recordings] and Cash’s end of his time voice is as powerful as it is poignant. Any imperfection in articulation in a system would come across as almost musical heresy, but here it was pitched perfectly. The gravelly, broken voice, with Cash fighting his own failing body comes across perfectly and the sound invites you to listen to ‘Hurt’ and the rest of the album.

The sound really fills out from there, adding bass depth and some forceful slam to the bottom end and some refinement and eloquence to the treble. Nothing is harsh, but similarly, nothing is artificially softened. Moving over to Neil Young singing ‘Southern Man’ [After The Gold Rush, Reprise], the sound remained light, boppy, and bouncy, but the added depth to the bass made you more aware of the left hand of the piano player underpinning the track throughout. Yes, the guitar (and Young’s voice) wailed sonorously, but it was that solid piano that sold the system to me.

As you might imagine, rhythm is a strong suit (it’s an obsession at Naim, and it’s one that seems to have rubbed off across the Channel too). Enter, er, ‘Enter Sandman’ [Metallica, Elektra], which stands or falls depending on the quality of that gut-churning rhythm. It’s not a great recording, but it is one of those you-can’t-help-headbanging moments, and this pairing puts you right in the theoretical mosh pit.

In case you think this Naim and Focal pairing is really only good for rock, guess again. I played the ‘Un Bal’ from Berlioz’ Symphonie Fantastique [Linn Records] and it behaved flawlessly, teasing out the playful themes with charm and portraying each with tremendous detail and the kind of dynamic range required to portray this recording with the right sort of scale. And ‘scale’ is the one of the system’s great strengths, moving from large scale recording to tiny jazz clubs, and everything in between, with aplomb. OK, this is more about dynamic scale than image size, but even on the size and shape of the imagery, this is a system that does well. I’d say this is not the choice for the soundstage freak, though.

The imaging on this system is good, and best described as ‘tidy.’ Instruments are presented with good solidity and sophistication, and the soundstage is slightly wider and deeper than the boxes, but it’s not the pinpoint precision that stereo image freaks crave. I prefer balance in a system!

A good system has limits, and the limits here are entirely understandable and predictable, too. The performance threshold is broad, in that you can play this system loud and you can play it relatively quietly. But push it too far in either direction and you understand what more buys you. Funnily enough, the most noticeable part is the lower-level playing, which can get uneven when played at whisper levels. Loud is better handled; there is some thickening of the sound, some shutting down of the image, and – if pushed to the max – the system can get too bright. But mostly it covers its tracks. Similarly, with the loudspeakers, swapping out normal listening room sizes for barns or wardrobes and the Kantas are either overawed or overdriving. This system sits in its own goldilocks spot in the audio hierarchy, and that applies to listening levels and rooms, too. But for most of the people, most of the time, the Focal and Naim duo make a very strong case for ‘stick a fork in me, I’m done!’ There’s no upgrade path because there’s no need for an upgrade path. These two are self-contained greatness.

 

The combination works better than it should in hierarchy if not electrical terms, and the synergy concept is beautifully worked here. Yes of course other brands are available, and both Nova and Kanta work fine in partnership with a range of loudspeakers and electronics respectively. But the two work together remarkably well.

Multiroom without tears

Naim Audio has incorporated some form of multiroom systems for years, with some success. However, the multiroom industry today is divided between millionaires with plant rooms designed to control lighting, heating, home security, audio, video, telephony, internet access, and home automation across several dozen rooms in a modern oligarch’s palace… or an iPad!

Like an increasing number of companies, Naim realised everything is about the app now. The app represents the nerve centre of any audio system, and if multiroom capability is demanded, the app is the place to meet that demand, head on. In the latest version of Naim’s own app, coupled to latest versions of the firmware on Naim’s latest generation of streamers, servers, and Muso one-box devices (like the Muso Qu-be pictured above), multiroom connectivity is ‘unlocked’.

A Naim multiroom system allowed both independent play in different zones (Richmond Fontaine through the main system, The Fall on one Muso, Nick Cave on the other, and lots of family therapy all round) or Party Mode (five devices playing in sync), controlling volume in each room if needed. Where this didn’t quite work was with old and new streaming generations, but the latest app makes for two-way ‘conversations’ between new products, and one-way to old. Cool!

dCS launches new Bartók upsampling network DAC with headphone amplifier

From the dCS press release:

CAMBRIDGE, UK: dCS proudly announces its Bartók network DAC and headphone amplifier – a singlebox, state-of-the-art digital-to-analogue converter with full network streaming functionality and Class A headphone amplifier.

Retailing at £9,999 for the streaming DAC and £11,999 for the streaming DAC with integrated headphone amplifier, the new dCS Bartók DAC brings together dCS’s past, present and future.

Replacing Debussy as the most affordable DAC in the illustrious dCS range Bartók shares the same DNA as its bigger Rossini brother, featuring the Rossini Ring DAC™, custom high-performance UPnP music streamer and dCS digital processing platform inside a simplified chassis that uses only one power supply. As with all dCS DACs Bartók measures best in class across all technical dimensions.

Bartók plays music through an array of industry-standard USB, AES or S/PDIF digital inputs. It can stream over Ethernet from a NAS drive or online music services such as TIDAL™ or Spotify™, and from Apple devices via Airplay™. The network interface can perform full MQA™ decoding and rendering. The DAC section is equipped with independent balanced and unbalanced line outputs that can drive power amplifiers directly, avoiding the need for a separate preamplifier.

The Bartók Headphone DAC features a custom designed headphone amplifier that works extremely well with both high and low impedance headphones in balanced or unbalanced formats. Taking the dCS analogue output stage as a starting point Bartók maintains that level of analogue performance at the same time as being optimised for a range of headphone impedances.

Bartók supports all major codecs including high resolution PCM and DSD, with user-selectable upsampling. There is a suite of DSP filters to tailor the sound to suit individual taste, and great care has been taken to minimise jitter at all stages with the dCS ‘auto clocking’ architecture. The network streaming section currently runs at up to 24-bit, 384kS/s and DSD128, supporting all major lossless codecs, plus DSD in DoP format and native DSD.

As with all dCS products, Bartók is designed and built in Great Britain to the highest standards, with aerospace-grade machined aluminium casework damped by internal sound deadening panels to reduce resonance. Multi-stage power regulation is employed, with twin mains transformers to isolate the DAC circuitry from the headphone amplifier. A choice of silver and black finishes is offered.

Firmware can be easily updated via CD, USB or the new automated download and update facility. This lets dCS add new features and improve the performance of Bartók over its lifetime – keeping it contemporary years after its rivals have become obsolete.

Bartók delivers an immersive experience with precision and detail captured inside a panoramic soundstage. Bartók plays music from any source in a vibrant and musically engaging way, with great dynamics and inky-black silences. This open window and faithfulness to the original recording is now available to headphone lovers too.

Summary:

• dCS Bartók network DAC with Class A headphone output (£11,999)

• dCS Bartók network DAC (£9,999)

• latest generation dCS Digital Processing Platform and Ring DAC™

• Supports UPnP™, asynchronous USB and Apple AirplayTM sources, plus AES

and S/PDIF digital audio streams.

• Class A headphone amplifier stage drives low and high impedance phones

• Streaming services supported include TIDAL™ and Spotify Connect™.

• multi-stage oversampling design, optional DSD upsampling; selectable filters

• auto-clocking system improves ease of use and minimises jitter

• Accepts encrypted SACD data from dCS Transports via Dual AES inputs.

• multi-stage power regulation and twin mains transformers

• firmware-upgradeable for future functionality and performance upgrades

Availability: Late October 2018

Quad Artera Solus integrated amplifier

This review highlights an international divide in the audio industry. Write about ‘Quad’ to many international audiophiles and it summons up images of classic electrostatic loudspeakers from the 1950s through to the present… and not a lot else. The same doesn’t apply to UK audiophiles, who also think of the company as the maker of some of the most reliable audio electronics in history, and a brand with a following that would make McIntosh blush. In fact, there is a generation of UK audio customers for whom Quad was the only trusted brand for audio electronics, even if they never used Quad loudspeakers.

The reliability of Quad electronics was so legendary, people bought the products on a generational basis: someone might only buy new Quad when they handed their decades old, still working perfectly amps on to their children, and 25 years later the pattern would repeat itself to the next generation. That changed recently, although not for the reasons one might think – more for the fact that audio technology moves at a faster-than-ever pace, and the notion of holding onto a device for a quarter of a century or more is alien to many modern audio buyers.

Products like the Quad Artera Solus, then, have to walk a tightrope: lean too far in one direction and the company risks disenfranchising its thousands of buyers who update at a glacial rate, but too much in the other direction and there are a lot of ‘mature’ products in the catalogue. The Artera Solus packs a lot into its one small yet heavy box. It’s a CD playing integrated amplifier that can replay at up to DSD256 performance from an attached computer using a USB port, has updatable firmware through a second USB port, and can stream music from an external source via aptX Bluetooth. There is no provision for network streaming on this model (but a second device is said to arrive by the end of the year with greater wired and wireless networking capabilities).

The chattering classes in high-end audio already have CD long dead and buried. They moved on to SACD long, long ago, and have now moved on to DSD over PC replay and full UPnP streaming. However, each time we review a product like this, a few quieter voices speak up about how they are still far from abandoning CD. The argument isn’t necessarily that they prefer the sound of CD (although many still prefer spinning polycarbonate to hard disk or SSD stored media), it’s simply because they might have been collecting CDs for decades and feel no pressing need to either rip those discs or migrate over to a Tidal or Qobuz. Quality disc-spinning all-in-ones are rare (AVM springs to mind) and even rarer at a reasonable price, so the Quad Artera Solus has something of a captive market.

 

It might be understandable, then, if Quad took a bit of a back seat on design, as competition is scarce at the price. This could so easily have been a ‘knock it out quick’ product that was simply a parts bin of Quad’s other devices thrown together on the cheap. But, outside or in, compromise was not on the list of development parameters. On the outside, it’s a minimalist piece of equipment (as is common to the rest of the Artera range, and a wider design brief shared the whole Quad electronics line), with a slot-loading CD drawer, a fluro display that doubles up as a control touch panel, a headphone socket, and a remote eye. The rear is more comprehensively equipped, and speaks of the Artera’s amplifier background, as there are line level RCA inputs and both RCA and XLR outputs, and a gaggle of coaxial and optical inputs and outputs. Heatsinks flank the sides of the Artera Solus.

Inside, the Quad Artera Solus is solidly designed and built. The slot-loading CD loads data into a buffer so it, like the USB input, feeds asynchronously to the DAC. The digital stage itself is based around the ESS ES9018 Sabre DAC, a 32bit eight-channel DAC that can support up to 32bit, 384kHz PCM and up to DSD 256 through DoP protocols from a computer. As the Artera acts as a DAC here, it’s platform and program agnostic (I used Audirvana Plus, as Quad recommends for Mac users, and would have gone with Foobar for PCs), although PC users will need to download drivers from Quad to unlock DSD and higher-rate PCM (a mini CD is supplied, but you can download from the Quad website). Quad allows the user to specify one of four filter settings; Fast (default), Smooth, Narrow, and Wide. I found the default to be perfectly fine in every setting, but your tastes and system may dictate otherwise. aptX Bluetooth music replay is also included, and the single rear-mounted aerial pulls in signals for about a 10m (in real terms) radius.

In solid-state electronics, Quad is perhaps best known for its feed-forward or ‘current dumping’ design circuit, which it has been using in its power amplifiers since the 1970s. However, fitting a current-dumping amplifier circuit inside the Artera Solus chassis proved impossible, as that chassis already comes filled with digital and analogue preamp gubbins. Instead, Quad went with a dual mono 75W Class AB design, fed by a large central 300VA toroidal transformer.

In a way, this is a hotly contended market, with many traditional brands releasing similar ‘all-in-one’ models. But, in another – probably more important – way, the Quad Artera Solus is almost in a market of one, thanks to its aggressive price point. Granted the more up-scale products from rivals come with WiFi streaming (something that should prove to be retrofittable when the next product in the line is released), but even in the light of that the Artera Solus still has a keen edge in price. And best of all, it doesn’t show! This looks, performs, and even sounds like an expensive product… just one that forgot to actually beexpensive.

Quad also faces the challenge of meeting the demands of existing users and new buyers, with the former often wanting the more mellow sound of components of a bygone age. And it’s here that Quad really hits home. There is an excellent sense of poise to the sound that answers the demands of Quad’s old and new fanbase perfectly. This is never going to be the most forward-sounding, beat oriented amplifier around, but neither does the Artera Solus fall into the ‘pipe and slippers’ trap. That’s a difficult tightrope to walk, and the Artera Solus walks it without faltering.

How this comes across is in a sense of true dimensionality to the soundstage, a more dynamic presentation than is usually associated with the brand (more in line, in fact, with the original Quad 22 power amps being fed by a more dynamic-sounding preamp), and lots of mid-band detail, which nonetheless retains the refinement and ease of long-term listening that Quad’s army of fans crave from the brand. And of those inputs, the CD acquits itself as being the best (followed by USB, then the standard connections, and Bluetooth bringing up the rear but doing so surprisingly well). This source combines the Artera Solus basic midrange clarity and detail with a sound that has some real drive behind it. Quad fans would baulk at discussing anything aside from classical music, so I played… Trentemøller. Even ‘Chameleon’ [The Last Resort, Poker Flat] with its gut-churning deep bass and the demands that places on a system, sounded energetic, full-bodied, and powerfully malevolent.

Of course, classical and jazz are Quad’s home turf, and the Artera Solus doesn’t disappoint. The Takacs Quartet’s interpretations of Beethoven’s late string quartets [Decca] are like a complete walkthrough of classical nuance, mixing drama, pathos, and even humour with a mastery that few have ever recorded with success. The Quad Artera Solus tracks changes in musical intent with precision, and yet does so with a sense of effortless dynamic range as a force behind the refinement.

Even power-chords and swampy 4/4 rock didn’t phase the Artera Solus, and it played ‘La Grange’ [ZZ Top, Tres Hombres, London] with gusto. OK, so perhaps not the same degree of gusto as experienced with a Naim Uniti Nova or a Moon Neo Ace, but gusto all the same. The headphone stage matched the rest of the amp perfectly, and it has its own amplifier behind it allowing for more demanding headphones to be played well. OK, so gruelling headphone loads might phase the Quad, but in the real world, it’s more than enough.

 

I almost missed the point here, because it’s so easy to associate Quad with classic British loudspeakers, that I hooked this to a pair Chartwell LS6/f floorstanding loudspeakers, and got that classic British sound – with a lovely midrange, albeit slightly soft at the top and bottom. Swap out the loudspeakers for a pair of meatier-sounding Wilson Duette II (not a combination I would necessarily recommend, but it worked all the same) and the full drama and dynamic impact of the Artera Solus came to the fore.

It’s always a sign of a good product that when you assiduously avoid knowing the real price and play the price-tag guessing game, you think the product is worth a lot more than its real price tag. And in playing that ‘guess the price-tag’ game, the Quad Artera Solus came out at closer to £3,000, rather than £1,500. OK, if it were £3,000, I’d be more concerned about the lack of wired or wireless network streaming, but that would be the main criticism (and given that a Wi-Fi module is said to be in the pipeline, even that crticism seems somewhat churlish). In sonic terms, style, and build quality, I’d say the Quad Artera Solus punches above its weight, even if it’s far too graceful a performer to ever throw a punch.

CH Precision, Wilson Benesch, and Nordost system

Suggesting that high-end audio has anything in common with Little Orphan Annie might seem like a stretch, but in one way at least they share a reality: for audio pilgrims who sign up to the quest for musical and sonic perfection, no matter how hard we try – or how much we spend – the constant evolution of equipment and technology means that the audio state-of-the-art is always a day away. No matter how hard we run we never quite catch up – and to make matters worse, these days the gap between dreams and reality has stretched to a yawning chasm. With more companies offering more and more expensive products, with speakers that shatter the six-figure price barrier seemingly run-of-the-mill, and with even a basic, high-end system costing more than a (very nice) car it’s harder to compete and far more confusing to try – not least because so many of the super-expensive products on offer so often fail to deliver on those rare occasions you get to hear them.

So why do we keep the faith? Because occasionally, just occasionally, you experience a system that really delivers – one that ticks all the boxes and keeps all the promises; one that is so sonically adept and musically capable that listening and music take on that addictive quality we all remember from the very first good system we heard – the system that set our feet on this path in the first place. This is one of those systems…

This combination of CH Precision Electronics and Wilson Benesch speakers, all laced together with Nordost’s ‘value option’ Valhalla 2 (well, it seems like value compared to Odin!) is one of those systems where the music just is. It doesn’t obviously explode into the room or cuddle you seductively, it isn’t propelled ever forwards by a metronomically toe-tapping beat, nor does it exist in a permanently cavernous acoustic. Instead, it just happens; a natural extension and impression of the original event, performance that is all about THE performance; that resides with the performers rather than the equipment in the system, that simply sounds like real people and real instruments. This is still recorded music, but it’s recorded music with that instantly identifiable quality, the gestalt character of the real thing – and that makes it rare and wonderful.

On the basic, material level, this system could be described as impressive, complex, extravagant, or just plain expensive. In fact, expensive doesn’t really cover it: in all honesty it demands the addition of a few adjectives – like “ruinously”, “eye-wateringly” or perhaps the simple, expletive quality of Ireland’s favourite descriptor, “fecking”. But there’s no denying that this system cuts no corners in its pursuit of audio and musical excellence. On paper at least, it looks like a classic, high-tech, high-powered solid-state rig, with a stack of front-end boxes feeding a pair of massive mono-blocs – and that’s partly correct. The CH electronics offer levels of software derived control and configuration that go beyond the necessary and well in to the realms of “because we can”. I mean, who needs to control not just the duration and brightness of the displays but the test colour as well – and if the nine colour options on offer don’t match your mood, shirt, or latest motor, there’s always the opportunity to dial in a specific RGB shade! But as easy as it is to poke gentle fun at such electronic excess, there’s a very real purpose behind it, the degree of configuration on offer allowing both topological simplicity and unparalleled versatility, the ability to adapt the amplifiers to the surrounding system to an almost unprecedented degree – and that has a direct, positive, and dramatic impact on performance.

This system is built around the L1 line-stage, supported by the X1 power supply and flanked by the P1 phono-stage and a pair of M1 power amps. Of course, it will accept digital sources, but the raison-d’etre for this system and, in a very real sense, the secret of its success is the declared intent to extract the considerable best from record replay. To that end, the P1 offers no fewer than three independently configurable inputs (two current sensing and one voltage driven) with variable gain and loading as appropriate, as well as the option to include switchable EQ curves – all for the princely sum of £22,400 (EQ Filter £1,300). At the other end of the chain you find not one but two M1 amplifiers, a wallet wringing extravagance in the sense that these are not mono-blocs – at least not all of the time! In fact, the M1 is five amps in one: a straight stereo, a bi-amp (one input, two identical outputs), an active bi-amp (two inputs, two independently configurable outputs), a mono-bloc with the whole power supply dedicated to a single output stage, or a high-powered, bridged mono-bloc. Meanwhile, gain, and the ratio of local to global feedback can be set to further match the amplifier to the speaker’s sensitivity and electrical demands. With a rated output of anything between 2x 200 and 700 watts on tap, perhaps it’s not surprising that a single M1 will set you back a slightly gasp-inducing £37,400, making a pair cost £74,800!

Compared to the P1 and M1, the L1 seems almost prosaically simple: inputs, outputs, and a volume knob. But that is to misunderstand both the remarkable care that has gone into the design and construction of the L1 – and the critical role of the line-stage in any genuinely high-end system. I’m afraid that, if you want realistic dynamics, full bandwidth, convincing staging, and a real sense of scale, then neither passives, auto-transformers, nor a direct output from your DAC will deliver. Real systems use active line-stages, despite the demonstrable difficulties of getting one right – and the L1 is one of the select few that actually gets it just right. It is both the heart and soul of this system and is, in a very real sense, the root of its greatness. Having said that, this is a set-up that takes no chances, so both the L1 and the P1 are backed up by the X1 external power-supply – just to be on the safe-side. It’s a wise decision, and the benefits are all too clear to hear, but it does add another £12,400 to a final price-tag of £110,900 for the electronics alone.

 

Just as well then that we’ve got the ‘budget’ options from the other suppliers, with neither the cables nor the loudspeakers representing their respective manufacturers’ flagship options. Nordost’s Valhalla 2 might use more conventional shielding and less metal than the Odin 2, but it shares the top product’s core technologies and all-important proprietary connectors – and it’s backed up here by their Q-Kore 6 grounding system, to help reduce system noise-floor and deliver realistic dynamics. Take one look around the back of the CH components and you soon realise what makes V2 make so much sense: when it comes to power cords this is one greedy system, with each power amp requiring two and the P1 and L1 still needing their own, despite the presence of the X1. Look at the price of Odin 2 power cords and all becomes clear…

The Wilson Benesch speakers might look familiar, but these are not the Cardinals. Instead, what we have here are the smaller but easier to accommodate and rather more elegant Resolutions, making up for their reduced internal volume by adding a Torus Infrasonic Generator to the mix. Named for another of Captain Cook’s vessels rather than their undoubted performance attributes, the new speaker shares the same driver and cabinet technologies as the flagship, but in a more compact, simpler and easier to govern package. The tailored response of the drivers makes for a minimal, phase-coherent crossover, while also delivering the often mutually exclusive attributes of tremendous low-level detail and a fully developed harmonic envelope. The cost in this case takes the form of lower than average sensitivity – which could impact dynamics except that the light-touch crossover makes the Resolution sound more efficient than it is while the system topology and L1/M1 combination takes care of the rest. Like other WB speakers this one just loves to be vertically bi-amped, which helps explain the over-kill option of that second M1, while in practice, I found that 10% feedback worked best on both the mid and the bass ranges, allowing me to run the amps in straight bi-amp mode, saving the price of a set of interconnects along the way.

After that? Well, there’s always Odin 2…

There are some systems that simply sound the way they look. There are others that are defined by their chosen technologies, be they direct heated triodes, horn-loaded drivers, Class A solid-state output stages, or more ceramic than you can shake a stick at. But then looks can also be deceptive and technology can be applied in many different ways. Examine this system on paper and – price aside (and Lord knows, that’s no reliable guide) – there’s little to suggest the magic lurking within. The CH Precision electronics, with their near identical styling and muted blue-grey casework couldn’t look more Swiss if they tried. The Wilson Benesch speakers offer, as I’ve already suggested, a familiar appearance and nothing new in terms of their technology. It’s all been done before, in previous WB designs. Yet, just as there’s an air of solid, compact competence about the CH pieces, the Resolutions have a certain confidence that comes from their balanced proportions and the sculpted elements from which they’re built. This is a speaker that just looks right and that alone, even if you think you know what Wilson Benesch speakers sound like, should give you pause for thought. Hear them on the end of this rig and you’ll almost certainly be recalibrating those expectations.

 

Sadly for the headline writers and band-wagon jumpers, there is no secret sauce in this system. It’s not about the what: it’s all about the how. This is an object lesson in understanding what a given product wants and then making sure it gets it, both in terms of interfacing between components and in designing those components themselves. Rich in terms of tonal colour and instrumental detail, the Resolutions need an amplifier set up that’s capable of delivering emphatic dynamics. Bi-amping helps but it’s all about clean, available headroom and just enough damping. Given their substantial size, you might well consider the M1’s 200 Watt per channel output as modest, but what it really reflects is the size of their power supply. Or as someone once famously said, the quality of the first Watt is really what matters – but then so does the quality of the other 199 just waiting to get past it. Add that to the ability to adjust amplifier damping factor via the feedback ratio and you’ve got pretty much the perfect match for the Resolutions, a match that’s heard in the weight, scale, and impact they bring to the more Zimmer-esque moments of the GOTsoundtrack [Sony] as obviously as it contributes to the vivacious attack and intimacy, cut, thrust, and counterpoint of the Stuttgart Chamber Orchestra’s scintillating performance of Eine Kleine Nachtmusik [Decca], a record that breathes new life into this most hackneyed of Mozart masterworks. Of course, the Resolution’s are getting an awful lot of help from the Torus. Just how much is evident from the totally OTT percussion on the Game Of Thronesrecording, but its sheer quality and seamless integration really comes into play on the fleet-footed bass arpeggios of the chamber piece.

As well as highlighting the temporal and spatial integration of the system, that Stuttgart disc also switches the focus of attention to the other end of the chain. One of the main reasons this Decca SXL recording sounds so wonderfully immediate and present is the ability to replay it with the correct EQ. Switch to the standard RIAA curve and the incisive brilliance in the playing is dulled, the energy level drops, the physicality diminishes, and the band recede. This is no matter of taste or preference. The Decca curve captures the frisson of this remarkable performance and RIAA doesn’t – and as we all know, any chain is only as strong as its weakest link. This system was built to reproduce the signals generated by a record player and I was lucky to have the Grand Prix Monaco v2.0 on hand. Combined with the Kuzma 4POINT14 and the Fuuga cartridge this is the most consistent, musically convincing record player I’ve ever used – a worthy front-end for this system. But even with a record player of such undoubted excellence, the ability to switch replay EQ on older classical and jazz pressings in particular was often the make or break factor when it came to delivering the difference between a good record from a stunning musical performance – from the self-same disc. Whether you need switchable EQ depends on the nature and content of your record collection, but its availability as an option on the P1 and underlines yet again how the versatility and configurable nature of the CH electronics plays directly into this system’s stellar musical performance.

Meanwhile, sitting quietly at the heart of proceedings, the L1 goes calmly about its business, the anchor to which the system’s absolute spatial and temporal stability are tied, the root of its remarkably low-noise floor and sudden dynamic response. In many ways it’s the understated star turn that sums up the whole system. Is it perfect? No – and nor is it beyond criticism. But the real quality of this system, the thing that makes it a system in the true sense, rather than a simple set of parts, is the fact that its flaws do not intrude. Yes I could ask for more individual dimensionality and intra-instrumental air. I could wish for even deeper bass and a shade more immediacy – but do I notice those things when listening? Not for a moment. Not unless I go looking for them – and I don’t do that because I’m so darned engaged by the music, the performance, and the performers. Perfect? No – but near enough for that not to ruin your enjoyment; near enough to deliver a timely reminder of just what’s possible; near enough to convince you that, as expensive as it is, this is one system that’s worth every penny. If you thought that the light at the end of the audio tunnel had finally flickered out, think again. It’s there, it’s stronger than ever – there’s just more ‘noise’ between you and it. This system isn’t a new dawn – it’s just the same old sun, shining as brightly or brighter than ever.

Audio Research, Sonus faber, Transparent cable system

Audio Research, Sonus faber, and Transparent Cable: that’s basically high-end audio royalty, all rolled into one extremely elegant and competent system. OK, so two of the three brands (Audio Research and Sonus faber) are subsidiaries of the McIntosh Group, but their autonomy and manufacturing smarts make them distinct entities in their own rights, and they have been a trio of brands known to work in harmony long before two of them teamed up!

The other common factor between these three well-established high-end audio brands is a desire to push the envelope. Any of these three companies could rest on some quite heavy laurels and coast for a decade or so. And, let’s be honest here, inertia is endemic in the audio industry and – digital audio notwithstanding – this is not the fastest-moving river in consumer electronics. But, despite – or perhaps ‘because of’ – that, all three brands keep developing new products that often take their brands in very different directions. The old days of the big, mellifluous sound of Audio Research and the warm and enveloping sound of Sonus faber are behind us. They walk a different path today.

However, for this system, we have chosen a mix of the old(ish) and the new. The old is one of the longest serving products in today’s Audio Research line-up, and the only purely solid-state product in its current portfolio: the CD6 CD player. Despite a fine DAC in the company’s Foundation Series (the DAC 9), CD is still a very popular medium with Audio Research owners, and the CD6 refuses to quit!

The CD6 is unashamedly old-school in places. Its one-colour faceplate harks back to classic Audio Research products, its top-loading transport is the superb NOS (new old stock) Philips Pro2 mechanism (Audio Research bought up the last batch) and the green numeric LED panel harks back to classic players of the 1980s and 1990s. If it ain’t broke, don’t fix it!

However, the CD6 is not some throwback from audio’s recent past. Alongside the CD mechanism, there are four digital inputs (two Toslinks, RCA S/PDIF, and an asynchronous USB connection), all of which are said to handle up to 24-bit, 192kHz PCM files. While not at the bleeding edge of TLA (three-letter acronym) technology – DSD and MQA are MIA – the CD6 is ideal for those with an extensive CD collection who have no burning desire to rip it to anything computery but might want to dip a toe into the high-resolution waters. If you find those waters so refreshing, you start looking to DACs in the future, the CD6 keeps your options open by including a BNC-equipped S/PDIF output and an AES/EBU XLR connector. Or you can stay with the on-board quad 24-bit DACs of the CD6 a little longer and use its RCA single-ended or XLR balanced line-level analogue outputs.

Talking of analogue outputs conveniently moves us to the core of the system; the Audio Research LS28 line preamplifier from the company’s Foundation series. In fact, Audio Research has been doing a spot of consolidation recently, and in line preamps, there’s now just a Good-Better-Best line-up (with the LS28, the REF 6, and the two box Reference 10 – with the GSPre and the rest of the GS line allegedly soon to disappear). This preamplifer features four single-ended RCA and four balanced XLR inputs, with two RCAs and two XLR outputs. Audio Research learned a lot from its most recent Reference series preamplifiers, and the technology (both solid-state and valves) has filtered through to the LS28. The audio circuit uses a quartet of 6H30 valves. This valve is fast becoming the popular choice for preamp designers wanting to move from the ubiquitous 6922 because they are reliable, long-lived, readily available, have low plate resistance, high transconductance, and requires no cathode follower. In short, even before you take sonic performance into account, the 6H30 is an obvious choice for a modern high-end valve preamp.

 

The other big aspect pulled from the Reference preamps is the logic control. This allows that big, two-deck green fluro display to access a wealth of information, allowing you to custom name inputs, control the shut-down system (ideal to prevent power-up or power-down thumps through power amps), assign pass-through for AV systems, and display the amount of hours elapsed on a set of tubes. As 6H30s are good for between 5,000-10,000 hours, there’s no need for clock-watching. Hard buttons on the LS28 are the large volume and source selector dials, and the sextet of push-buttons to power up the preamp, access the menu, run the preamp in mono, invert the phase, or mute the preamp altogether. These are replicated on the remote.

The newest addition to the group is the VT80 power amplifier, which can be – and in our case, was – provided as a VT80SE. Or you can cut out the middle-man and just go for the VT80SE. The difference between the two is the power valves, with the VT80 configured for two pairs of KT120s, and the VT80SE sporting two pairs of KT150s. As the two are electrically identical, this is an easy upgrade, and the two share the same clever auto-biasing circuit, the same pair of 6H30s (I said it was proving popular!) driver tubes, the same option of RCA single-ended or XLR balanced input and either four or eight ohm outputs. We pay a little more for the VT80SE in Europe because we are afraid of the universe and demand hot valves be caged for our protection. More enlightened parts of the world demand freedom for tubes!

Audio Research spends a great deal of time selecting KT150 valves, and the company’s ‘Certified Matched’ versions (supplied with the SE) have been through a secondary quaity control pass that ensures they have tolerances 10x tighter than a standard matched pair straight from the family. This effectively means a 48 hour burn-in before final sort, and there are always those who get hot under the collar about 1.6% of the typical 3,000 hour lifespan of their valves lost to testing, but I’d take tighter tolerances every time. Such is the quality of performance from KT150s (as evidenced by the fact that every other current Audio Research power amp or integrated amp has switched to these valves as standard), I can’t really imagine anyone short-changing themselves with the KT120 version.

The Serafino Homage Tradition is a wholly new model in the evergreen Homage series from Sonus faber. In the past, the line moved from the Guaneri standmount, through the Amati floorstander to the wide-baffled Stradaveri, but this last was dropped when the range was relaunched in 2017. Instead, the Serafino is the mid-point between the two-way standmount and the 3.5-way Amati. Billed as ‘everyday luxury’ the Serafino is also a 3.5-way design but features a scaled-down cabinet and smaller bass drivers to make the loudspeaker a little more approachable in typical European listening rooms. It sports the company’s innovative laminar ‘Stealth Ultraflex’ rear port (making the design technically a para-aperiodic reflex cabinet) and its ‘silent spikes’ (part of the company’s ‘Zero Vibration Transmission’ system), which are a metal/elastomer sandwich design preventing any stray cabinet resonance from leaking out into the listening environment through the floor.

 

Sonus faber has long used a Damped Apex Dome (or Arrow Point) soft-dome tweeter in its higher end models. This 28mm design is coupled with a 150mm pulp midrange driver with a neodymium magnet, and a pair of 180mm bass cones. Such is the elegance of Sonus designs that neither this nor the pair of 220mm cones on the Amati make the loudspeaker look particularly imposing. Of course a big part of that is the boat-backed design and the frankly gorgeous polished Wengè with maple inlay and titanium details, and coffee-coloured leather front baffle. Sonus faber advertising really pushes the Riva motor launch styling for a reason: you see either in the flesh and you want one. It’s that simple. The only difference between a Serafino and a Riva Aquarama is the price… and that you can’t go waterskiing in a loudspeaker. On the other hand, this loudspeaker is also styled and finished in the way that really does honour violin makers and high-end piano makers.

The last link in the chain is Transparent Cable. Transparent’s Reference series of interconnects, loudspeaker cables, and power cords have been around for some time, are highly prized, and fully upgradable to the company’s Reference XL line. Each cable in the line features its own network box, precisely attuned and optimised using the ‘this’ rule: this network for this length of this specific cable. The cables themselves feature multi-strand twisted pairs of high-grade copper for their conductors, feature non-metallic components in the design of their plugs, and sit in extremely well made braided outer sleeves. We used balanced interconnects throughout.

As suggested earlier, if you are expecting the traditional Audio Research and Sonus faber values, you are sadly mistaken. This is perhaps one of the most perfectly poised and constructed systems, ideally optimised to work together in absolute harmony, but those old concepts of the rose-tinted Audio Research and the lush-sounding Sonus faber are far out of date. This is a system that’s surprisingly clean and bright sounding. Not so bright that it’s forward or pinched, but it definitely adds a sense of sparkle to music.

I’m not big on drug references and am dead against promoting the use of recreational pharmaceuticals, but if I recall my wilderness years, there’s something about music played through this system that’s like the world seen through the filter of a small amount of cocaine. I’ve been told. Not a full snootful, but just enough to bring out the best in everything. And similarly, this system is a bit ‘moreish’; you want to use this stuff more and more, but at least this sytem doesn’t end in tears, and a drugs bust.

Unlike other high-end systems though, this one is relatively fine with compressed albums. ‘Sleeping by Myself’ from Eddie Vedder’s Ukulele Songs[Monkeywrench] is a fine example of a compressed album that masks hidden depths. There’s some difficult rhythmic work hidden in the basic strumming of a ukulele here. No system can rescue the album from its compressed prison, but they can make it seem less bleak and thin, and this system makes it sound entertaining.

What this system does exceptionally well is fill a room with sound. The soundstage is large and deep, possibly deeper than wide in most rooms. There is a sense of a stage rather than a forward, enveloping presentation, and there is a palpable sense of living, breathing musicians in a solid three-dimensional space. My go-to check track for this is ‘Memphis Soul Stew’ by King Curtis [Live at Fillmore West, ATCO]. It’s an outstanding live slow-build from one bass guitar, to a full-sized funk band, complete with horn section, piano, two types of percussion, and famous names like Billy Preston, Bernard Purdie, Jerry Jemmott, and Cornell Dupree. Each instrument is introduced, the musician plays a few licks, and joins the build-up. On a good system, you can follow each musician in turn, shift focus from musician to musician and back again, and never once lose the musical theme and the infectious rhythm. And that’s precisely what this system does so well. Yes, I’ve heard systems that have even more of a ‘walk-in’ feel to the sound (including a few from the same stable) , but invariably they are either vast and unwieldy designs that require a room the size of an aircraft hangar, or they cost a King’s ransom. Or both.

Everything about this system is both effortless and in good order, which kind of makes for great listening and very dreary writing. Every aspect of the performance is exceptional and outstanding, but the system is so unfussed by such things and just gets on with playing music, you are hardly aware of these performance high points. Take the system’s dynamic phrasing for example; this system has the sort of microdynamics and ability to create tonal shades that were simply not possible a couple of decades ago at any price. Now, it makes that truly staggering sound so easily, that you almost overlook it. Only when you realise you are listening to the hi-hat in a piece of music where a dozen other musicians are playing at absolutely full tilt, do you appreciate just how good this system really is at reproducing music.

 

If there is a comment – and I use the word advisedly – it’s that sparkly brilliance it brings to music is possibly not the last word in absolute neutrality. It’s not as rich and as exciting as you might expect, but it is making a sound that is better than the original. Many of us would happily put up with such a compromise, especially as it doesn’t seem to favour one genre over another. It just sounds good with music, whether that music is classical or driving rock.

We’re at something of a new dawn for Audio Research and Sonus faber. Both the Foundation series from the former and the Homage Tradition line from the latter are now both well-established and demonstrably meld together brilliantly and shows great promise for future combinations. This is a fun sounding system, too. It’s not just cerebral or visceral, it’s entertaining, and that’s one of the great missing components from some of the more straight-laced audiophile brands and systems. Neither stuffy or fluffy, the combination of Audio Research, Sonus faber, and Transparent Audio pull together in perfect harmony here – both figuratively and literally.
