Linn 360 with Pistonik motor system preview

The Linn 360 loudspeaker is already a known quantity round these parts. https://hifiplus.com/articles/linn-360-floorstanding-loudspeaker-2/ Whether in full Exakt active mode or used as a passive loudspeaker with an active bass component, it’s Linn’s shot across the high-end bows. But, like any loudspeaker, it’s hobbled by the nature of the drive units used in most loudspeaker systems. That all changes with the launch of the Pistonik motor system. These are replacements to the 6” upper bass and 8” woofer units in the 360. They will be available as standard to all 360 models from today. In addition, existing 360 users can get them as an upgrade.

In fairness, this hobbling isn’t the fault of most drive units. It’s a combination of things coming together to make the drivers a bottleneck in most systems. Most drivers are off the shelf designs, even if modified to suit a specific need. That means the characteristics of the driver is designed to cover the greatest number of installations. In addition, as a passive system, the drive unit maker needs to be extremely conservative. This is because the upstream amplifiers are unpredictable.

While car analogies are massively overused, it fits here. Most drivers are a little like a production saloon. They are perfectly good and designed for a wide range of drivers. A suspension and drivetrain that comes with a sneeze test. You can take your eyes off the wheel long enough to sneeze and not find yourself in a ditch. Compare this to the British Touring Car Championship, or NASCAR. Now, you have a car with a suspension and drivetrain that reacts to every twitch and movement of the person behind the wheel.

The gloves are off

Linn’s 360 is different. It’s full of known qualities. The Exakt active system or active bass system in passive operation means the way the drivers are driven is entirely controlled. There are no speaker-blowing low-powered valve amps or voice-coil melting ultra-powerful amplifiers. In addition, when you design loudspeaker drivers for a specific loudspeaker enclosure, you get the potential to make a drive unit with the gloves off.

Of course, whether that’s a freedom for a manufacturer or a chance to just make in-house drivers largely depends on how innovative that company’s R&D team is willing to go. And in Linn’s case, they go deep! Rather than take an existing design, Linn went all in and rethought the loudspeaker driver motor. This is the part where the voice coil passes through the magnet. They created a very long-stroke travel through the magnet thanks to a significantly extended magnetic gap. That gives the voice coil an order of magnitude longer travel.

That new motor requires a re-invented suspension system. In the 8” driver, for example, the unit uses two spiders in place of just one in the basket of the speaker. Meanwhile, the drive unit material itself is hard aluminium, to reduce cone break up while retaining low mass.

Such driver tech isn’t just thought up in a dream. It takes a lot of physics. Linn is one of the few companies who use the COMSOL multi-physics modelling program.

Coming soon…

We’re not going to go into too much depth here; for that, read our review in Issue 256 out in early June. But it’s a big change. Playing some traditional ‘fat lady sings’ opera, in the already very good 360, she sounds angry; with the new drivers, she sounds furious! It wasn’t a magnifier on the sound, just laser focused on the music. More importantly, that focus means nothing is off the table. Pick some music not known for its audiophile quality – ‘Know How’ by Young MC for example. That’s old school rap from 1989, complete with janky 80s-era samples. That’s not the kind of thing that ever gets played in audio shows or demonstrations, because it rarely sounds good. Here, it rocks! You have the pumping backbeat reproduced in all its glory.

I moved from Beethoven piano to ‘Rumble’ by Skrillex and everything in between, and in all cases the drivers start and stop with blistering speed, powerful depth and excellent dynamics. It’s fast when you need it, full and rich when you don’t. But, breaking the music down into its audiophile components seems wrong; it’s all about playing music more.

That’s the point, here. The science doesn’t need some granular overview of how the music sounds; it just sounds better. Yes, given that bass drivers are the change, bass is tauter and faster… but more importantly the space and clarity of the midrange and treble get cleaner and more detailed thanks to those bass units.

No debate

If you are reading this while staring at a pair of existing 360s, there’s no debate. This is your next upgrade. Spend ten minutes comparing the two, and you spend two minutes comparing the two and eight minutes arranging and paying for the upgrade. Fortunately, it’s a two-hour dealer fit rather than a Return To Manufacturer upgrade. For new buyers, the 360 is a little more expensive and a lot better… and now with a real-walnut finish. Eather way, once you hear it, you won’t want to be separated from your speakers for too long.

Stack Audio SmoothLAN Regenerator

I’m not sure how Theo Stack does it. All the network filters on the market at around the £750 price point of the latest Stack Audio SmoothLAN Regenerator are passive devices in plastic boxes. The Stack unit has a machined aluminium case and a separate power supply, which makes it look like remarkable value in material terms alone. 

Stack Audio has always used machined aluminium casework for its electronics, keeping costs down. When I asked how Stack achieves this, Theo explained that it has smaller margins than other brands and sells directly rather than through retailers.

Not big, clever

The SmoothLAN Regenerator is not a huge device at 10.5cm (four inches) long, but if you look at the underside, you can see no fewer than 36 bolts holding it together. These give some indication of the nature of what goes on inside, where there are nine separate compartments containing three stages of reclocking and filtering to clean up the incoming network signal.

The separation of the filtering stages blocks external and internal EMI, which is emitted by pretty well all electronics and can get through the smallest of gaps, hence the need for so many fixings in the Regenerator. The standard SmoothLAN is a smaller, passive filtering unit, as the suffix indicates the SmoothLAN Regenerator does not merely filter but regenerates the network signal to strip out the noise that typically pollutes network connections. 

Regenerator_Baseplate_Black_01

There don’t appear to be many network regenerators on the market. The known one is the Uptone EtherRegen from the US, but a quick search didn’t reveal any others. I wanted to know whether the SmoothLAN Regenerator works as a single input switch, but Theo says it doesn’t operate similarly.

Uncompromising

It uses two stages of passive filtering and three active reclocking stages to produce a 100mb output that is “noise-free for uncompromised music streaming.” Stack provides a short (50cm) unbranded ethernet for connecting the filter and streamer, which I used for this review. Results would likely improve if this were upgraded.

The reclocking stages require power; a 5V low-noise switch mode plug-top supply connects to the SmoothLAN Regenerator via a USB C socket between the in- and output ports. The connecting cable plugs into the power supply rather than being fixed, as is usually the case. 

I discovered this when it was accidentally pulled out. Each circuit block within the SmoothLAN Regenerator has its power supply, while the clock supply is further isolated to minimise phase noise and jitter.

I assessed the Stack SmoothLAN Regenerator by trying it with various streaming devices with and without a fancy Network Acoustics Tempus switch, which provided a fair degree of isolation. The first set-up consisted of a Melco N10 server/streamer with its USB output connected to a CAD 1543 MkIII DAC (also featured in this issue). 

I played Bob Dylan’s ‘Tangled Up In Blue’ from the library on the Melco and then put the SmoothLAN Regenerator between the incoming network connection and the server. The Stack Audio’s inclusion resulted in a distinct relaxation of the sound but not a smoothing of detail. In fact, leading edges became better defined, and it was easier to appreciate the kick drum and the guitar playing. At the same time, the track gained more drive and emotional impact. The combination of impetus and ease made for a significant overall improvement.

Making it easy

Using a track from Qobuz, Ike White’s ‘Changin’ Times’, and switching from ‘regular feed’ to ‘Stack filtered and clocked’ produced a larger improvement. Streaming service sound quality has greater potential for noise gathering and never sounds as good as locally stored material, but the SmoothLAN Regenerator tried to balance this out. There was more power in the bass line, more space in the sound overall, and a better definition of leading edges.

This last quality gave the tune a more precise sense of timing whilst bringing ease to the presentation, which was very welcome. The song really got into its groove with the Stack in line, with greater separation of the percussion, guitar, drums and bass line. I also contrasted the Stack Audio SmoothLAN Regenerator with another network filter at a similar price. This comparison was a closer run, as you might expect. Still, there were things the SmoothLAN Regenerator could do that the alternative did not—notably, depth of image, a general increase in detail resolution and all-important relaxation. 

Analogue beats digital?

Analogue sources always beat their digital counterparts on the sense of ease; digital can do detail, dynamics, and even bandwidth, but it’s rare to find one that sounds as relaxed as a good turntable. The fact that the Stack brings some analogue-style ease to the result is most welcome. 

The second source I combined with the SmoothLAN Regenerator was an Electrocompaniet ECM1 MkII streamer (reviewed in Issue 242). I started with June Tabor’s rendition of ‘Love Will Tear Us Apart’ from Qobuz. This filter’s cleaning up of the sound and enhanced image projection gave the singer’s voice a more subtle expression in a tonally richer and refined soundstage. 

Stacked from 4 images. Method=A (R=2,S=2)

The SmoothLAN Regenerator seems to deburr the sound and remove roughness by reducing noise; it brings out the purity of a voice like this and delivers greater definition. Overall, this positive result encourages further listening and makes this streaming service more appealing in a revealing system.

Someone recommended Camille Bigeault to me recently, this French drummer plays with a degree of temporal precision that would impress Steve ‘The Metronome’ Gadd and the track ‘Mental Web’ certainly lives up to its name. Here, the Stack regenerator helped to make the piece more accessible by opening up the space and dynamics while adding shape to the kick drum. The drums took on a presence in the room that was not there before, essentially turning an almost flat presentation into a three-dimensional one thanks to greater clarity across the board, which is most apparent in the midrange where the guitar and leading edges reside.

What surprised me was that this piece of math rock took on an emotional weight inaccessible without the SmoothLAN Regenerator. Presumably, because everything was more transparent, it was easier to appreciate the subtleties and virtuosity of the musicianship.

Open wide

With a more familiar track in ‘Straight No Chaser’ by Keith Jarrett, Gary Peacock and Paul Motian [The Old Country (More from the Deer Head Inn)] the addition of the Stack filter opened up the soundstage, expanding it from between the speakers to outsides of both. More exciting is the way that it allows the life in this live performance to become palpable, expanding the space where the performance took place so that you can hear the musicians playing more clearly and the way that the venue’s acoustics react, essentially letting more detail through in a coherent manner.

The last piece of hardware I set up to try the SmoothLAN Regenerator with was an Innuos Zenith SE server/streamer. Initially, I played a song from the drive, ‘So Begins the Task’ by Stephen Stills, and left the Tempus switch between the network and the Innuos. Adding the Stack to this chain was nonetheless beneficial, with a sense of grain reduction, making for greater flow and a smoother, more analogue sound with greater vocal projection once again. It went from being a beautiful track to a sublime one. I also tried the Ginger Baker Trio piece ‘Ramblin” from Qobuz, while rolling back to a generic network switch. The result was consistent with earlier tests; an apparent increase in energy but also speed. The playing went from being good to absolutely thrilling and made for far stronger listener engagement.

Congratulations!

Stack Audio deserves congratulations for bringing this build, finish, and sound-quality product to the market at such a competitive price. The SmoothLAN Regenerator’s solidity inspires confidence in longevity, and its weight means that it won’t be pulled off the shelf by heavy ethernet cables. If you fancy hearing what your streamer can do when freed of the many nasties that beset most networks, I would encourage you to give it a thorough spin; it will not take long to appreciate what it can do.

Marantz 60n

Marantz is far from alone among audio companies in having undergone several changes in ownership over the last decade or two. But Marantz is a company that, in nine years, has been acquired by Sound United, which was itself acquired by Masimo in 2022, and, as of 2025, is now in the hands of Harman. Change of ownership is the sort of upheaval and uncertainty that might have provoked a lesser company, perfectly understandably, to take its eye off the ball just a little. 

Marantz, though, is not a lesser company—it has forged ahead regardless. And if ever a product indicated that while a brand may not be sure of exactly where it’s heading, it most certainly knows where it’s coming from, it’s this 60n. 

All present and correct

The 60n is the correct product and at the correct price. £1,299 put Marantz’s way buys a well-specified, good-looking, beautifully built integrated network streamer equipped to do everything a mainstream customer might realistically expect. The control options are good. The finish is just about interesting enough to make it stand out. As long as the 60n can compete where performance is concerned, the Marantz will seem to be an attractive prospect for any presumptive new owner.

‘The correct product’, in this instance, means ‘an integrated Class A/B stereo amplifier with network streaming smarts, an accessible ESS Sabre ES9018K2M DAC of 32bit/384kHz and DSD256 native resolution, and that can easily become part of a multi-room system’. You’re good to go if you have a pair of speakers and a smartphone with a music-streaming app.

The Marantz 60n can twist out 60 watts of Class A/B power into an 8-ohm load, rising to 80 watts per side into 4 ohms. Its DAC is accessible via digital optical, digital coaxial, USB-A and Ethernet inputs and wirelessly via Bluetooth 5.4 dual-band wi-fi. The wireless aspect of its specification allows it to be Roon Ready and can support the ‘Connect’ versions of both Spotify and TIDAL music streaming services, too. Install the ‘HEOS’ (‘home entertainment operating system’) control app that’s free for iOS and Android, and as well as the ability to access further music streaming services and internet radio providers, the 60n can form part of a multiroom audio system with appropriate Denon and/or Marantz equipment.

Side with analogue

The analogue side of things has not been neglected, either. Three line-level inputs (on unbalanced stereo RCA sockets) are joined by a moving magnet phono stage, and there are pre-outs for use with a subwoofer and with a power amp. Sturdy SPKT-1 binding posts for a single pair of speakers complete the back-panel line-up.

The 60n has a floating section ahead of a slightly contoured, slightly patterned metal front panel that changes appearance a little depending on how the light catches it. A relatively small ‘porthole’ display keeps the ‘traditional Marantz’ flag flying, and there are controls for volume, balance, bass and treble along with a ‘source direct’ control that bypasses those last three. A power on/off button and a 6.3mm headphone socket complete the front panel. Build quality and the finish standard are well up to the standard the asking price demands.   

In addition to the control app (which is comprehensive enough but rather slapdash in its layout), the 60n can be controlled using a large and logical remote control handset. Getting what you want from the device and positioning it within a multi-room system is very straightforward.  

Able driving

The Marantz 60n ably drives a pair of Bowers & Wilkins 705 S3 Signature loudspeakers on their bespoke FS-700 S3 stands for the test. Sources consist of a Clearaudio Concept turntable connected to the MM phono input, a Rega Apollo CD player connected to both the digital coaxial and one of the line-level analogue inputs (to make a straight A/B comparison between the Rega’s DAC and the equivalent in the Marantz), a FiiO M15S digital audio player loaded with hi-res digital audio files of various types, and an Apple iPhone 14 Pro housing Presto and TIDAL music streaming apps. The Marantz can also access a Buffalo Terastation NAS device thanks to its Roon compatibility. 

The 60n sounds fuller, more complete and more convincing if given the proper stuff to work with. But it’s well worth noting that the Marantz doesn’t throw in the towel if ‘the proper stuff’ is not forthcoming.

Don’t sweat the lesser stuff

So while a heavyweight 180g vinyl pressing of The Hold Steady’s Stay Positive [Vagrant] is preferable to a 320kbps MP3 of the same album streamed via Bluetooth, and while a 24bit/96kHz FLAC file of Arvo Pärt’s Cantus in Memoriam Benjamin Britten performed by Staatsorchester Stuttgart and Dennis Russell Davies [ECM] proves a better bet than its 16bit/44.1kHz CD-borne equivalent, the 60n doesn’t turn its nose up at the lesser stuff. Instead, it treats it with a degree of care that’s by no means a given in products similarly specified and priced.

There’s a smooth unfussiness to the overall sound of the 60n that makes it a) an adaptable device, and b) appropriate for use with any number of price-appropriate loudspeakers. Its low-frequency presence is decently robust and just fractionally forward where the entire frequency response is concerned – with carefully controlled bass attack, allowing for cogent rhythmic expression. Detail levels regarding tone and texture are impressive, too, and there’s slightly more low-end variation available here than the norm.

Shine scintilla

The top of the frequency range is a little circumspect when it comes to outright extension, and that last scintilla of shine and brilliance is missing from the treble response, too. But the high-end activity is substantial rather than hard, and it’s just as detailed and informative here as it is at the opposite end. But it’s in the midrange that the Marantz is at its most adept and most impressive – and not only because of those powers of detail retrieval that make every singer sound characterful and direct. It’s open and revealing, sure – but its tonal balance is carefully neutral and its facility with the minor harmonic variations apparent in every voice makes for a naturalistic and convincing listen. 

The whole frequency range hangs together quite nicely, that little hint of low-end overconfidence notwithstanding, and there’s a fair amount of dynamic headroom available when the intensity (or straightforward volume) of a recording ramps up. The Arvo Pärt recording makes it apparent that even the most minor, most transient dynamic shifts in harmonic response aren’t overlooked, either.    

The soundstage the 60n creates is coherently organised and quite spacious, too – so even a massed orchestra can find space for every participant to operate. The left-to-right layout is broad, and there’s a mild but definite suggestion of front-to-back and even top-to-bottom. The Marantz is unified in its presentation, knitting even the most complex recordings into a single occurrence rather than presenting them as a series of individual events.       

Just the facts

The Marantz 60n isn’t the most vigorous or assertive listen. For all of its dynamic potency, it’s a slightly matter-of-fact listen: “The facts, just the facts” would seem to be its mantra. And for those who value a calm and judicious presentation of their music, this attitude is approaching ideal – but those for whom music is, first and foremost, entertainment could find the 60n a little lacking in animation. Its ‘fact-led’ trait can be mitigated just as easily as it can be compounded by the choice of partnering loudspeakers, of course – and, to a lesser extent, by the source equipment the Marantz is amplifying. But even though some judicious system-matching is definitely in order, there’s no way to refute the attitude of the 60n ultimately. You either like it or you don’t.  

Like it or not, though, there’s no denying the 60n is an admirable device in many ways. There’s the way it presents itself, of course, and how it makes your music sound – no matter where it originates. But, there’s the way it’s a Marantz product, the likes of which yet another change of ownership seems extremely unlikely to undermine.

hARt Lab Tune Three

There are some curious patterns in reviewing. Having gone years without looking at a hybrid power amplifier, no sooner was the PrimaLuna Evo 300 back in its packaging that I was tapped up for another take on the same principle. While they might share a basic theme, the hARt Lab Tune Three is a somewhat different beast compared to the PrimaLuna and, indeed, almost anything else. 

hARt Lab is based in Chalandri, Greece, and focuses exclusively on building amplifiers: pre, power, and integrated. The preamps are all valve-based designs, but the power amplifiers (and the solitary integrated) mix valves and MOSFETs to secure the best characteristics of both. The Tune Three takes this basic concept and adds many unusual or downright unique design features to it. 

Unique construction

The unique aspect concerns how the Tune Three is constructed. Where most power amplifiers at this sort of price employ metal in their construction, generally resulting in something with the density of a neutron star, the hARt Lab instead employs amorphous wooden fiberboard in such a way as to be rigid in the ways that hARt Lab wants it to be but flexible in others which they claim dampens unwanted vibrations and mechanical noise feedback, resulting in lower noise floor and eliminating crosstalk. The company also puts its money where best needed; in the circuit. The base also incorporates ‘FloatO’ integrated anti-resonance feet to assist this further. 

The rest of the chassis also uses fibreboard with the same intentions. These panels receive the MICoat luxury painting procedure for a genuinely impressive finish. The side panels can also be removed and swapped for ones in different colours and finishes to suit.  

The amplifier housed in this chassis features a dual mono design that employs one CV181 (commonly known as a 6SN7) valve operating in a zero feedback driver stage, paired with a MOSFET output stage. The 80mm height of the CV181 accounts for the relatively tall overall height of the hARt Lab, as there is ample clearance between the valve’s top and the top cover. Power is rated at 165 watts into eight ohms, increasing to 275 watts into four, figures that should provide considerable freedom in speaker selection. The power supply responsible for this is a VAcc battery emulator with custom-wound mains transformers. hARt Lab asserts that the outcome is unaffected by external power fluctuations. The entire amplifier is then wired with a single grounding point. 

No impedance difference

You’ll find a single pair of RCA inputs and two sets of speaker outputs at the back. These do not differ in impedance like an all-valve amp and don’t switch independently, so they seem designed to assist with cabling choices rather than anything else.

hARt Lab equips the Tune Three with IR triggers, allowing it to power on and off with a compatible preamp, and it should hopefully be intelligible to other devices as well.

The resulting amplifier looks, and I think more importantly, feels unlike anything else I can remember testing. The clever aspect for me is that while the Tune Three is lighter than most other amplifiers in this price range, it doesn’t feel insubstantial. You can tell that a significant amount of time and energy has gone into its construction, and it has a very distinct character of its own. The blue LEDs glowing inside are used as low-noise reference diodes in the cathode bias circuit, making them a lot more than a mere design features.

Fifteen colours

The illuminated logo on the front panel can be adjusted to one of 15 colours to better match other displays, which is another fascinating detail. The Tune Three undeniably feels different from other amplifiers at this elevated price point, but it possesses a clearly defined character that will appeal to those for whom climbing the pricing ladder doesn’t necessarily mean an increase in mass.  

I connected the hARt Lab to my resident Chord Electronics Hugo MScaler and TT2 DAC, with the latter serving effectively as a preamp. It then outputted to the resident Kudos Titan 505 speakers, a design that can realistically be classified as slightly ‘valve unfriendly.’ Before any music was played, the hARt Lab did commendable things for anything containing valves. It is utterly silent at idle and powers both up and down without any unwanted noises. Aside from a slightly lengthy start-up sequence, it’s as easy to live with as a well-sorted solid-state amp. 

The sound of silence

This is interesting because once you stop listening to the sound of its silence and instead focus on its actual sound, the hARt Lab’s character becomes more reminiscent of a pure valve device. Listen to The Phosphorescent Blues by The Punch Brothers [Nonesuch], an album that is catnip to vacuum tubes, and the hARt Lab responds in a way that suggests there is nothing but those CV181s in there. Chris Thile’s delicate vocals offer a presence and sheer realism that surprised me, even though I’ve used this album as test material since its release. 

Keep listening, and this impression solidifies, but with some interesting and largely beneficial caveats. The hARt Lab has a truly fabulous midrange, as you might expect, but it isn’t emphasised over the rest of the frequency response. The top end, in particular, is energetic and detailed while being enormously refined at the same time.

Not so seismic

The bass available isn’t as seismic as that of some purely solid-state devices, but the same definition found in the upper registers provides a clarity and presence that is convincing. In terms of bandwidth, the hARt Lab’s MOSFETs certainly make their presence felt. 

The solid-state aspect of the Tune Three truly shines- besides the fact that I can listen to the Titans at volume levels that are decidedly un-valvelike- in how the hARt Lab performs like a solid-state amp. Enjoying the seventies-tinged ‘Outta Sight’ by The Sheepdogs [Self Released] on the hARt Lab is a genuine pleasure. It brings all those swaggering seventies details to the forefront of the mix, sounding rich and utterly believable. It also grips every time signature with a confidence that transforms this album into an absolute riot. ‘Scarborough Street Fight’ becomes something completely rhythm-driven; a track you simply cannot sit still to. This amplifier is perfectly capable of having fun when it desires to. 

Genuine audiophile

Of course, when you provide the hARt Lab with a genuinely audiophile recording, it responds magnificently. Stanley Jordan’s unique cover of ‘Eleanor Rigby’ from his Magic Touch album [Blue Note] is ideal for the hARt Lab. Jordan’s distinctive style enables him to effectively play two melodies simultaneously on the same guitar, which can sometimes sound somewhat confusing. Given the amount of information being conveyed, one might overlook just how remarkable his performance is. In this case, the clarity and three-dimensionality available allow you to appreciate the complexity of one man and a guitar, enhancing the magic of the performance rather than diminishing it. This isn’t a soulless disassembly; it’s more like a glimpse behind the curtain to understand how things work. 

This effortless ability to make sense of what you listen to means that the hARt Lab’s true capabilities only come into focus after a few hours. At some point, you realise you are somewhere between five and fifteen albums in, and the amplifier itself hasn’t crossed your mind once, but you’ve enjoyed everything that has come from it without hesitation. It’s the electronics equivalent of soft power, and the hARt Lab excels at it. 

Talent

Of course, at this price point, there is no shortage of exceptionally talented rivals, many of whom, by virtue of using casework that could double as a convincing blast shield, appear and feel more spectacular than the Tune Three. hARt Lab has taken a gamble that the Tune Three’s unique appearance is enough to entice you to sit down in front of it and have a listen. From there it stands on much more solid ground because this singular amplifier does an incredible amount right. This is realistically the best hybrid I’ve had the pleasure of listening to, and it is likely to win many admirers.

It started nearly 100 years ago (the centenary is in September this year), pioneering underwater echo-location and growing into a substantial company by the 1930s, working on airborne sound-location systems before the invention of Radar. The first forays into audio reproduction came after the war with turntables, and by the mid-1950s, ELAC was one of the largest German brands in this field. It wasn’t until the 1980s that they started building loudspeakers. Today ELAC has headquarters in the US and in Kiel, Germany, and makes a broad range of speakers, from Bluetooth to the Concentro M 807, the flagship in a relatively small range of six high-end stereo models.

Sheer numbers

You can’t help but notice the sheer number of drivers on the Concentro M 807. There are 11 of them across three surfaces of the gently curved cabinet. Most are grouped on the front baffle, with an array of six small cones surrounding a planar JET tweeter. The 40mm cones cover the high midrange, while the two 115mm cones above and below them handle the lower mids from 650Hz to 2650Hz. The lowest frequencies, up to 150Hz, are covered by a pair of 250mm aluminium sandwich cones on either side of the cabinet, nearer the plinth.

Most of the drivers on this ELAC have aluminium sandwich cones, except the six midrange drivers, which, due to the required low moving mass, feature a pure aluminium cone design. The midrange cones are faceted for extra pleasure, or, more technically, to increase stiffness, and their surfaces resemble the inverse of a faceted jewel; a fact that becomes apparent only in bright light or close inspection. From the listening seat, they don’t look that different from regular drivers. It would be worth angling your LEDs just so if you listen with your eyes open. They sound better without such distractions, however.

Diffuse enhancement

The reason for the circular array of small midrange cones is dispersion or directivity control. Switches on the back of the speakers allow the user to change the dispersion pattern and scale the soundstage, for both room tuning and personal taste. The five settings offered include ‘concentric’, which “forms a larger virtual point source. This mode increases directivity, focusing the soundstage between the speakers while reducing reflected sound for a more intimate, pinpoint experience.” ‘Diffuse enhancement’ “broadens the soundstage, enriches ambient cues, and creates a more immersive and atmospheric experience.” While ‘depth emphasis’ “focuses energy inward, enhancing depth and dimensionality. The result is a soundstage with increased layering and spatial realism.”

As there is a switch on each speaker, these settings can differ between channels and be used to compensate for room boundary variations. If one speaker is closer to a side wall than the other, you could set it to the depth emphasis position to reduce reflections. Concentric mode is the purest variant, as all the drivers operate in unison in a conventional manner. However, the extensive array of crossover networks has been designed to minimise compromise in any of these settings, no doubt.

I did wonder why the Concentro M 807 has so many panels covered in heatsinking on the back, but looking at a cutaway image of the insides reveals that each of these five elements has some form of electrical components behind it. I don’t think I have ever seen a more extensive crossover array – clearly it’s not easy to provide the directivity control offered on this speaker, which explains why it’s not a feature I have seen elsewhere.

Strong core

The cabinet is far from your average rectilinear box. The only flat surfaces are the sides, which taper backwards. The rest is gently curved to enhance stiffness and reduce internal reflections. The baffle thickness is not specified, but it tapers and looks pretty chunky at the central core section. Those looking for the reflex port are best directed to the cutaway, as this element vents underneath the box into the area provided by a steel plinth. This elevates the cabinet and allows the base to be angled, avoiding a parallel surface to the top and increasing stiffness. The base also provides a broad footprint and fixings for large conical feet, which are supplied in a dark chrome finish with matching floor receptors.

Replacing DALI Epikore 9 floorstanders, which are nearly as great in mass and cost in the system, the ELAC Concentro M 807s made it clear from the outset that such factors have little bearing on sonic character. This is a disciplined speaker that is in full control of its faculties, regardless of what you throw at it. There is no mincing of words nor fluffing of lines. You hear what’s in the signal and not a lot more or less. In other words, these ELACs are extremely clean, revealing and capable of delivering whatever the source and amplification manage to send their way. Precision is the word, but not in a take-no-prisoners way, just in a sense of doing very little to color or massage the sound for one effect or another. 

No limits

I placed them so the front baffles were a metre from the rear wall, as per the DALIs, and hooked up the Rega Solis power amplifier, equally precise and delivering 150W of Class AB power, via a William Eikos Ultralitz cable. The result was astonishing levels of detail, resolution, image specificity, wide bandwidth and high power handling. I’m not a level freak, but these felt as if there were no end stops. Apparently, there is a bigger version in the pipeline, so presumably people with larger rooms and amplifiers want more, but the Concentro M 807 never showed any sign of strain in my system. And boy, did they deliver power when it was required. Kick drums in particular seemed to kick harder and with more clarity of shape than usual, thumping me in the chest with surprising visceral impact.

Solidity of image is another obvious strength. Many speakers can make the bass sound solid, but the higher up the frequency range you go, the harder this becomes. Fully rounded high frequencies are surprisingly rare. But these ELACs delivered the same sense of three-dimensionality across the board, and this makes for very real live sound if the recording is up to the job.

Pipe down

A current favourite is Bill Frisell’s East/West, from which the track ‘Pipe Down’ is a highlight, but one that doesn’t always work at high levels due to its high intensity. Here, however, it proved to be chock full of thrill power, with a close-your-eyes-and-you’re-there sense of realism. It made it a lot less painful that I wasn’t at the concert 20 years ago. 

These ELACs aren’t as relaxed as the DALIs or a Vivid say, but neither are they aggressive or forward. They are perhaps just a bit keener on detail. This makes them fussier than average about recording quality and capable of making the better productions sound spectacular. If the music is laid back, so is the sound. JJ Cale’s 5 is a great example. You get the tight but loose sound of the band, the analogue fluidity of the recording, and that sense of ease that only Cale seemed to manage.

A recent piece of baroque interpretation on ECM, Gianluigi Trovanesi and Stefano Montanari’s Stravaganze consonanti, can easily sound brash and forward thanks to its scratchy period instruments and piercing woodwind, but here it was totally magnificent and made me want to play the whole album. The ELACs play the straightest of bats and reveal so much detail in such a coherent way that the music you love really comes alive with their help.

Precise and coherent

I was initially concerned that the Concentro M 807s were a technical tour de force, that their dispersion adjustments would mess up timing, and that musical enjoyment would be limited to a few audiophile productions. I am glad to say that they are nothing of the sort. Precise and totally coherent, these ELACs make a very good case for the technologies and construction choices made in Kiel. 

I suspect that if you wanted them to sound more laid back, all that would be required would be a source and an amplifier of that ilk. They are as transparent as you could ask for and as honest as the day is long. They are also extremely capable for their size and price – high resolution, high power, and features like dispersion control are never inexpensive, and you get an awful lot of all three in this sharply styled ELAC.

Wilson Audio Autobiography preview

The Autobiography by Wilson Audio is the Autobiography of Wilson Audio. It’s also the Autobiography of the listener. Those three elements intersect instantly, but it takes time to put that into words.

That doesn’t mean an excuse to wax lyrical, although that’s something of an inevitability. No, it’s that your first reaction when sitting in front of the Autobiography is quiet, intense processing. I sat in front of the Autobiography with three other audio reviewers. At least three of us are known for being loquacious. If there’s a witty or sarcastic comment to be made, at least two of us will try to make it with the slightest provocation. And all four were silent, just drinking in what the Autobiography could do. It took a good ten minutes before anyone could say anything; not just about the loudspeaker… anything.

This is not a review. A handful of dealers and reviewers flew to Utah in late April to see the new Autobiography launched at the nearby Springville Museum of Art, learn more about it at the Wilson Audio factory, and listen to it in the Provo listening room, built by Sheryl Lee and the late Dave Wilson. The listening session ran for a couple of hours, with a small group of four or five in the room taking it in turns to sit in the hot seat.

Jet lag advantage

I’ve turned severe jet lag to my advantage here. The embargo on discussions about Wilson Audio’s Autobiography lifted while I was somewhere above the Labrador Sea. By the time I landed, all I had were a few brief notes, the start of a nasty cold, and a burning desire to sleep for a week. Rather than simply deliver the same as everyone else, just a few hours late, I decided to check the comment sections and address some of the many ‘observations’ that are inevitable when a company releases a $780,000 loudspeaker.

By now, Wilson Audio’s Autobiography itself is something of a ‘known unknown’. The design, architecture, and basic specifications are the ‘known’ part, already discussed at length. So, I’ll keep it brief; it’s a six-way (ish) design with a vertical midrange-tweeter-midrange array flanked by two 7” ‘Pentamag’ lower-midrange drivers, and an inverted-dome rear-firing tweeter in the upper lower-midrange cabinet (read that again; it does make sense… honest).

The upper gantry

These drivers all sit in an upper gantry with an exceptional amount of adjustment for time-alignment. The lower cabinet, on which this intricate array of cabinets and verniers sits, holds 12” and 15” bass drivers and features a refined version of the clever front-or-rear vent found in the Chrononsonic XVX.

Each driver has its own ‘firsts’, but the Convergent Synergy Laser Sintered tweeter and the twin 2” MID (Midband Integration Driver) dome designs are particularly interesting. The tweeter sits in a clever 3D-printed housing with a rear wave chamber that acts almost like a tiny anechoic space, improving energy dissipation and reducing internal reflections. Meanwhile, the upper-midrange dome sits in a waveguide that makes it look like the dustcap of a larger midrange cone. It’s only when you see it on models with metal trim details that you realise the ‘cone’ is the driver’s faceplate, and you begin to see it for what it is.

Five alive

That said, the five-ALNICO-magnet arrangement at the rear of the lower-midrange units is also an exciting new development, improving on the QuadraMag drivers used elsewhere in the Wilson Audio line-up.

All these drivers are made to Wilson’s exacting specifications, and none has been used in any previous Wilson Audio loudspeaker. With the company’s trickle-up/trickle-down ethos, in which the technology and drivers of previous models filter through to the next, there has never been an ‘all-new’ Wilson driver complement since the company’s first WAMM. So, ‘off-the-shelf drivers’ or ‘mid-range Scanspeak units’… yeah, riiiight!

Autobiography sits at the top of the Wilson Audio range, yet it stands 8 cm/3.15” shorter than the WAMM Master Chronosonic. Don’t get too complacent. Even without spikes, the Autobiography still stands at 206 cm, which is a little over 6’ 9” or 0.954 standard Shaqs. Much of this weight is borne by the enclosure, with the gantry uprights and midrange front baffles made from Wilson’s own H-Material, vibrationally sensitive components made from its V-Material, and the cabinets made from X-Material. These combine to deliver optimal damping, structural integrity, vibration control, and stiffness in the right parts of the loudspeaker.

The dimensions and driver complement are just the start of the story, however.

Just look at it

Let’s be clear about the Autobiography. With a finish that places it in the same class as Patek Philippe and Rolls-Royce, the prospective purchaser will spend a long time simply looking at the loudspeaker. It’s a voyage of discovery, and each time you look at the loudspeaker, you find something new. The different kinds of guilloche (engine turning) on the metalwork are inspired, sometimes in straight lines, sometimes curved around a point. And in the metal band that joins the two sides of the 3D-printed tweeter housing, there is an almost prismatic geometric pattern.

Then there are unheard-of levels of adjustment, and it’s here that horology sort of steps aside; there are gear wheels, bridges and verniers, but no train of wheels or parts that need maintenance and lubricated jewels to keep it running. There’s also no need for a desk full of watchmakers’ tools to adjust the Autobiography. All of it can be done by hand, eye, and ear. And, at 372 kg/821 lbs/2.53 Shaqs per speaker, quite a few elves trained in piano moving and loudspeaker installation.

Easy unlocking

Wilson Audio has made its adjustments easy to lock and unlock. Take the rear MTM alignment cam. It is adjusted by turning a metal cylinder with a small, fold-out lever. Fold the lever back, and the toothed rear of the cylinder locks into place. The action of that alignment system is ‘buttery’ smooth… and irresistible. I will lay bets that every Autobiography owner will unlock the cylinder and give it a few turns. Fortunately, Wilson thought of this, and the setup comes with two sets of data sheets for each customer, so both they – and their dealer – know the correct alignment points for the loudspeakers.

But what’s the point? Our hearing system is highly temporally sensitive. We can detect time-domain errors of just a few microseconds, and this is one of the key components of hearing that doesn’t degrade with age. Most fixed-baffle loudspeakers can achieve in-room time-domain coherence of about 100µS, but our hearing can resolve coherence errors at around 10µS. The Autobiography improves on the WAMM’s 2µS. When everything arrives at the listener’s ears at the same time, our brains do less heavy lifting in interpreting the sound and have an easier time listening to the music. So, ‘what’s the point of all the metalwork?’ To get you closer to the music.

Smaller footprint

Despite having larger bass drivers, the loudspeakers have a slightly smaller overall footprint than the WAMM, making them suitable for installation in any room where the Master Chronosonic XVX can be used. While room size is rarely a consideration at this level, there are people for whom the WAMM was a step too far. Similarly, the Autobiography presents a slightly less demanding load than the WAMM, although, once again at this level, finding a partnering amplifier is never going to be a problem.

This loudspeaker stands as tall as most basketball players, weighs slightly less than a new Harley-Davidson Road Glide, and costs as much as a very nice 3,000 sq ft family home in the town where it was built. Bespoke is included in the package. Five standard, 15 upgrade, 11 premium pearl, and seven premium ‘Colors of the World’ cabinet finishes, with chrome or black-chromed hardware, offer at least 76 possible combinations; factor in different grille finishes and there are hundreds of permutations.

An introduction

The photographed finishes are merely an introduction; of the four built examples, I thought the white-with-chrome hardware version in the Wilson home was the nicest-looking. In particular, the white had an almost pearl-like iridescence. Regardless, this isn’t a shrinking violet of a loudspeaker; it’s a bold statement of intent, both on Wilson Audio’s part and that of the owner. No apologies are demanded, no quarter given. Which is probably the only reason why Mr “I’ve seen more attractive Daleks” won’t be buying a pair.

Wilson Audio Autobiography

We live in an age where ‘megacars’ (cars delivering more than 1,360 horsepower, or 1 megawatt), sit above ‘hypercars’ (with around 800 horsepower) and both sit above ‘supercars’ (with around 600 horsepower). As you move further into this ultra-high-performance realm, the cars themselves become more uncompromising in design, and that is reflected in the price.

The same applies to almost every discretionary purchase today; everything from Vertu phones with a concierge service, hand-made Namiki fountain pens that cost as much as a car, women’s handbags that cost as much as a fleet of cars and watches with price tags so large, the mainspring will wind down before you’ve finished counting that high.

The Autobiography isn’t the first loudspeaker to enter this ‘ultra’ stream, nor will it be the last. Technologies developed in this loudspeaker will end up in the next series of ‘My First Wilson’ speakers, and that development is amortised here.

Dancing

I’m dancing around the big topic; how does it sound? That’s the ‘unknown’ part for all but a select few right now. I’m dancing around it in part because the terms are beyond us. We tend to define sound reproduction in terms of its limits, putting those limits into siloed parameters – the soundstage was wide and deep, the vocals detailed and articulate, and so on. But as we get further up the mountain, those limitations shrink, and we begin to describe the sound as a musical event. Maybe that explains The Silence of the Wordsmiths.

The demonstration itself was designed to take the listener from the soundstage through the bass in stages, then to the expressiveness and personal nature of Autobiography listening. At each step, there wasn’t much to reference against in absolute terms, leaving almost all other loudspeakers wanting.

Letters

Soundstage, for example. The use of ‘Letter’ by Yosi Horikawa (which begins with someone dipping a pen in ink and scribbling from the far left through the centre of the image to the right, before it develops into a percussive rhythm piece) is a difficult test for any loudspeaker, as there’s a strong chance of a clearly recognisable tonal or staging ‘dip’ between the speakers; nothing of the sort happened, and you’re left with the sound of a close-mic’d scribbler at their desk… rendered perfectly. For a big loudspeaker, it gets out of the way almost completely.

So it was with each successive track. You were ‘in’ the music and the mix, not just in terms of soundstage, detail or dynamics; you had an emotional connection with the sounds being made on a level that only seems to happen rarely. It’s why people are still bonded to their electrostatic designs and why others have their loudspeaker ‘forever home’ in horn loudspeakers. The two do things very differently, but I always maintained that if you could mix the transparency of a panel with the energy of a horn – without taking on the downsides of both types of design – you’d have a loudspeaker that gets tantalisingly close to the real deal. Or at least, it gets us all out of Base Camp on our climb up the mountain.

Something different

The Autobiography does just that. And in the process, pushing the sonic envelope does something different for the listener; it bypasses the audiophile-noodling part and reconnects with the music on a very deep level. Sure, being able to feel at least some of that 32’ organ pipe in Westminster Abbey pumping out 16 Hz is a remarkable experience (and not one you get from a CD; you need someone who was there with recording equipment that can process sub-20 Hz sounds). But once you get past the impressive, you start to unpack the personal, the music with meaning. And for once, that meaning jumps out at you immediately.

I found myself drawn to playing intensely personal tracks. I chose to play ‘I Loved a Man’ from the 1958 West End production of Valmouth, not because it’s a good recording – it isn’t. Not even because I knew the voice well – although I did. I chose to play it because some know the singer as Patsy Rowlands, but I knew her as ‘mum.’ Some atavistic part of my brain knew I’d be able to hear her voice in a way I hadn’t since she died 21 years ago.

Memorable moments

The Autobiography does that for you… The clue is in the name. Had I had more time with the loudspeaker, I would have been drawn to those memorable moment tracks; the one that was playing when you met your better half. That music that was playing in the background when you heard something life-changing.

Maybe it was the jet lag talking, but that night, around 4am, I found myself wide awake, crying over the loss of my mother, something I hadn’t done in years. That’s the impact these speakers can have on you. It’s more than a humbling musical experience. It’s something far deeper that gets you more in tune with the music than you might ever expect.

Three kinds of Autobiographers

There are three types of music lovers for whom the Wilson Audio Autobiography will resonate: owners of the WAMM Master Chronosonic, owners of the Master Chronosonic XVX, and those seeking the ultimate in loudspeaker performance.

The first of those is perhaps the most interesting of the three; I suspect those hoping for second-hand WAMM Master Chronosonics to appear may be disappointed. That’s not because of the performance; it’s for the same reason Ferrari owners who have an F40 will never part with it. The F40 was Enzo Ferrari’s last project before he passed, and the WAMM Master Chronosonic was Dave Wilson’s last, great project. I think it’s more likely that many WAMM Master Chronosonic owners will ‘second home’ that loudspeaker but will place the Autobiography in their main system.

With the two other groups, things get a lot easier. The only qualifiers to the Autobiography discussion in both cases are “how soon can I get a pair?” and “which colour scheme do I choose?” That last might prove long-winded.

This is as far as I go with the Wilson Audio Autobiography. I couldn’t fit a pair into my listening room and even if I could, for me it would be less of a ‘purchase’ and more of a ‘mortgage.’ But there will be buyers, and those lucky few will have one of the best musical experiences they can get this side of the real thing. And last time I looked, neither Jimi Hendrix nor Bill Evans is touring these days. Should the rest of us be jealous? A bit, but we should also hope that what makes the Wilson Audio Autobiography so good can filter down to our orbits.

Fyne Audio F701SP

The Fyne Audio range of loudspeakers can be bewildering; sometimes, they’re keen to ensure every available market niche is covered and preferably overlapped. While this means that for the most part, regardless of what your needs, there will be a Fyne Audio loudspeaker to meet them, this does risk creating something akin to menu paralysis (“Do I want this one, or should I stretch the budget to that one, and if so, what about that other one…?”) and confusion (“So, remind me, what’s this one called…?”). It sometimes helps to think of them as a Friends episode: ‘The one that looks like a 1960s studio monitor’ or ‘The one that looks like a New York fire hydrant’. Or is that just me?

The F700 range is ‘The ones with the cool, boat-backed cabinets’, ranging from the 5” F700 bookshelf to the 12” F704 floorstander. And now there are SP (Special Production) variants of the F701 (8” stand-mount), F702 (8” floorstander) and F703 (10” floorstander), the F701SP, F702SP and F703SP, respectively. The SP suffix means that they use the F700 series cabinets married up to the same driver and crossover tech as the top-end F1 series (‘The ones that look like a New York fire hydrant’), which is to say, their highest-spec drivers and (in-house cryogenically treated) crossovers employing high-grade components such as ClarityCap capacitors and Neotech PC-OCC wiring. 

Until now, the F1 series had a significant performance advantage over the F700 series, but the F1 series’ looks are somewhat polarising. Not everybody appreciates the form-follows-function approach of the F1-8 (and its bigger siblings), and I suspect the SP series might find favour with some of those folk. It certainly should. The F701SP is a stand-mount/bookshelf design with Fyne’s top-end 8” point source driver – realistically, though, you’re not going to get the best from a pair of £6,500 loudspeakers on a bookshelf, so let’s go with ‘stand-mount.’ 

Style with function

The elegantly curved and skilfully crafted cabinet appears modern and will attract those who prefer a contemporary style. However, like all Fyne products, this piece is not just about aesthetics; the cabinet’s curves disrupt internal standing waves, and its extensively braced design utilises high-density birch plywood for enhanced sonic neutrality. The F701SP features an IsoFlare design, which includes a 200mm mixed-fibre mid/bass cone and a 25mm magnesium dome compression tweeter co-located in Fyne’s classic point source configuration, ensuring that the acoustic centres of both drivers align for optimal time and phase coherence with an isotropic radiation pattern. An internal waveguide for the tweeter provides a flat frequency response and minimises internal reflections. 

The main driver uses Fyne’s fluted roll surround, which reduces reflections from the edge of the driver cone, where it fixes to the structure. It’s a very classy unit and easily justifies using the high-class crossover componentry it receives here. The crossover supports bi-wiring, and Fyne supplies nicely made links for single-wired use, with no horrid bits of bent brass on the terminals; it also benefits from their in-house deep cryogenic treatment, which carefully controls the cooling and warming cycle to better suit the needs of the components, not a generic cryo cycle. That’s one benefit of making these loudspeakers locally in Fyne’s new Glasgow factory.

Layin’ down some Trax

F701SP’s bottom plate features Fyne’s ‘BassTrax’ tractrix diffuser, which deflects the cabinet’s downward-firing reflex port output into a spherical, 360-degree wavefront. This port design minimises any ‘noises off’ from the port and helps the bass output drive the room with fewer constraints as to placement. It’s not a small cabinet; the port aperture and diffuser add a little height and weigh in at a reasonably chunky 14kg, but the neatness of the design means it’s relatively unobtrusive and looks smaller than it is. 

Aesthetically, I’ve always liked the F700 series’ boat-backed style, and it’s clean, modern, and unfussy. The F701SP comes in standard gloss walnut, black and white piano finishes. However, there’s also a matt natural walnut option, and all finishes cost the same. The curved, sloping top panel also helps reduce the impression of size, though it does make it more difficult to confirm the levelling of the speaker. Fyne offers matching speaker stands, which provide mass-loading options.

The level of performance available from the F701SPs does mean that it rewards the time and care taken with ancillaries, setup and placement. Such attention delivers a level of focus, precision and control, which is by no means a given at this price. Once correctly set up, there’s a directness to the F701SP’s delivery, which some may initially find disconcerting, but I’d say this is one of the speaker’s great strengths – it does an outstanding job of simply getting out of the way of the music.

Directness

Take ‘Giants Causeway’ from the Chaos Orchestra album Island Mentality [Chaos Collective], for example. There’s an immediacy and vitality here, a raw energy reminiscent of a live event: ebullient, free and unconstrained, raucous in the best sense. It’s an album of talented musicians having a great time, and the F701SP serves as our party invitation. ‘Landing Ground’, the title track from Laura Jurd’s previous album [Chaos Collective], is tight, fast and tuneful; the choppy strings, piano and bass are immaculately timed and placed, allowing for a greater appreciation of the fluidity of Jurd’s phrasing on the trumpet. 

The whole is like a beautifully seasoned dish, with nothing out of place, all designed to work together; speakers who deliver in a clumsy manner or demonstrate uneven timing make it significantly harder to appreciate the music and the musicianship involved here. This is why the F701SP’s directness is such a strength.

Lest you suspect this is merely code for ‘brash’, I have heard the Paul Tortelier/Jean Hubeau recording of the Fauré Élégie [Erato] sound glassy and hard on some systems; however, through the F701SPs, Tortelier’s cello is richly woody and sonorous, beautifully contrasted against a crisp, clean piano tone. The playing is at times emphatic, bold and assertive, while at other times lyrical, featuring liquid phrasing and subtlety that only two musicians who understand each other could achieve without it sounding overwrought. An album of emotive music devoid of histrionics and any hint of brashness would disrupt the spell. Similarly, the ‘Benedictus’ from Karl Jenkins’ The Armed Man [Virgin Records] transitions from heartbreakingly sentimental to a sudden, full-throated celebration. On a less nuanced system, this can feel like a disconnect and a bit gauche. Here, it makes more sense, reflecting the mixed feelings at war’s end through the juxtaposition of joy and loss. 

Joanna MacGregor’s performance of ‘Libertango’ on Live in Buenos Aires [Sound Circus] was supposed to be accompanied by the Britten Sinfonia, with whom she was touring. However, they could not perform that piece with her that night. Instead, she played it solo, with an almost defiant energy that renders the orchestra’s role nearly redundant and fully deserves the tumultuous applause she receives. It’s a tour de force that many stand-mount loudspeakers struggle to portray convincingly because it requires scale, weight, dynamic energy, control and agility. That’s a big ask for any loudspeaker; stand-mounts can offer agility and focus, but not always back it up with scale and energy. Thus, the fact that the Fyne Audio F701SP handled it quickly emphasises what a particularly communicative loudspeaker it is.

Fyne line

There is a fine line between exciting and overblown, and the Fyne Audio F701SP navigates it exceptionally well. These are not simply party tricks; the driver and cabinet possess enough scale and reach to deliver outstanding performance in any standard-sized room, whether on a large scale or with more intimate music. They also exhibit the sophistication and agility to tackle complex or demanding material. The F701SP features excellent timing, precision in the leading edges of notes, a rich tonality and a natural sense of air and space. Its dynamic range breathes freely, lacking any prominent reserve or constraint, establishing it as a versatile speaker of considerable talent. If, like me, you occasionally experience menu paralysis, the Fyne Audio F701SP may be the only loudspeaker you require.

Accuphase E-700

Accuphase has an impressive track record in Class A and Class AB amplifiers. The company was started in 1972 in Japan by brothers Nakaichi and Jiro Kasuga as Kensonic and, 10 years later, changed its name to Accuphase, which is derived from ACCUrate and PHASE. Over the intervening years, it introduced more than 240 different models and currently produces mainly amplifiers and CD players.

Class A amplifiers have long been praised for their sound quality. My very first proper hi-fi amplifier was the original Sugden A48, and it was a sweet-sounding amp, too—one reason I was keen to try out a modern-day Class A design.

Uncommon

Class A amps are less common than Class AB as they are less efficient (typically less than 30% compared with 50 to 70% for Class AB) and run hot, so their power output is often limited. They get hot because the power output transistors run at higher bias levels than in Class AB and are always on, drawing constant current even when idle. However, because they are always on, they avoid the crossover and other distortions that occur when the transistors in a Class AB design come close to the zero point as the waveform ‘crosses over’ from the positive to the negative swing of the signal. This zero-point crossover gives Class A amplifiers a superior sound.

The E-700 (35W) is the latest Accuphase Class A integrated amplifier, launched last year. At £10,500, it sits below the Class A E-800S (50W) at £14,000 and replaces the old E-650. Accuphase also has two Class AB amps in the range—the E-5000 (240W) at £12,500 and the E-4000 (180W) at £8,500, with a model below that expected later this year.

The E-700 is a Class A monoblock design rated at 35W into 8 ohms (the E-650 was 30W), 70W into 4 ohms (E650 – 60W), 140W into 2 ohms (E650 – 120W), and 160W into 1 ohm.

Flagship configuration

The power amplifier sections use the same configuration as the flagship E-800S, but with four sets of MOSFETs in a push-pull configuration as opposed to three in the E-650, with a beefy power supply using a sizeable toroidal transformer and large 56,000uF 50V filtering capacitors. 

Accuphase quotes a high damping factor of 1,000 for the E-700 (up 25% on the E-650) thanks to the lower output impedance of the four-fold output stage, its negative feedback circuitry and the use of a MOSFET switch for speaker protection as opposed to mechanical relays.

In the preamp section, Accuphase has introduced a totally new AAVA volume control circuit that does away with the conventional variable resistor approach, which, it says, has an adverse effect on sound because of changes in impedance, especially at settings that correspond to normal listening levels. Instead, it feeds the input signal to a voltage/current converting amplifier, where 16 switches provide more than 65,000 possible volume steps. The signal then passes through the ANCC noise-cancelling circuit, which is said to improve noise performance drastically.

Action-packed

Being a Japanese product, you will not be surprised to hear that the E-700 bristles with facilities. The front panel looks minimalist at first glance, with two large knobs to select input and adjust the volume on either side of the central VU meters. Flip down the hinged flap under the meters, however, and you will find rotary switches for speaker selection and tone controls, balance, a power amp in selector (balanced or line) and monitor loop, plus buttons for DAC (optional extra board), MM/MC and MC load (if using optional phono board), subsonic filter and phase inverter (when using a separate preamp) and one to take the tone controls out of circuit. Next to that flap is a headphone jack and an attenuator button that cuts the volume by 20 dB.

On the rear panel, the E-700 provides five line-level RCA inputs, two sets of balanced XLR inputs, a monitor loop for a recorder or equaliser/signal processor, preamp out and in – balanced and unbalanced – plus two sets of speaker binding posts for either two sets of speakers or one pair bi-amped or bi-wired. There is no built-in DAC or phono input, but these are available as optional plug-in boards.

A Class A act

I was lucky enough to get to listen to the E-700 not only in my home system, using an Audio Note CD-T Five transport and Audio Note DAC Five Special through Russell K Red 150Se speakers, but also in the listening room at retailer Signals near Felixstowe – I’d just dropped in for a day’s visit while visiting a friend in the area – where it joined an Accuphase DP-770 CD player and Dynaudio Contour Legacy speakers. My listening comments encompass both sessions but suffice it to say that my impressions of the E-700 were identical in both locations.

UK distributor MusicWorks also supplied me with their own ReFlex Ultra G5 mains distribution block with ReVive Ultra II mains leads, which made quite a remarkable and worthwhile improvement to the performance of my home system compared with a standard mains block and leads.

When I settled down to listen, it was clear from the first few bars of Ben Sidran’s ‘Shine a Light on Me’ from his Enivré d’Amour CD that the E-700 was a class act. The bass line that drives this superb track along is tight, deep and melodic, and the drumkit has excellent dynamics and punch, while delicate cymbal detail was well separated and presented. Sidran’s vocals were open, well focused and articulate, and his play on the DX7 synth was easy to follow. The track really moved well, and its quirky rhythms were well portrayed.

All wheat, no chaff

Another track that sorts the wheat from the chaff is guitar legend Larry Carlton’s fantastic version of the Doobies’ ‘Minute by Minute’ on his Discovery album. This track has a wonderfully sinuous bass line with some great twists and turns, and the E-700 conveys it with great control, weight, and movement. Carlton’s guitar was well-voiced, and I could hear how each note was shaped and played. Drumkit also had a great snap and syncopation with good dynamics. 

My favourite Bruce Springsteen track is ‘Racing in the Streets’ from his Darkness on the Edge of Town album. I played it on the E-700 as it is an excellent test of a system thanks to its superbly open vocal and piano on the intro and a bass line that will blow your socks off. The E-700 passed with flying colours – his voice was open and expressive, the piano had weight, presence and space around it, and when that superb bass line kicked in, it was deep, tight, agile and easy to follow. And when the bass guitar and kick drum played together, it was tight and rock solid. It conveys the sheer energy and dynamics of the track well, and the powerfully emotive vocals make this track unique. 

Although I enjoyed playing many more tracks during my time with the E-700, the last track I will share with you is ‘No One Emotion’ from George Benson’s superb 20/20 album. This track flies along at a breakneck pace and has fantastic energy, driven by a compelling and gorgeous bass synth line. The E-700 conveyed the sheer drive of this track, while Benson’s vocals were open and delivered with great emotion and the panache that makes Benson special. 

During my time with the E-700, I also had another well-respected rival that cost a little less than the E-700, which I greatly liked. What struck me about the E-700 compared with that amp was how much more dynamic and exciting it was without fatigue. The E-700 had a dynamic energy that the cheaper rival lacked and more significant insights into musicianship and vocal delivery. 

Authority

No matter what I threw at the E-700, whether vocals from Randy Crawford, Luther Vandross, or John Mellencamp, rock from ZZ Top, or jazz from Miles Davis or Lee Ritenour, the amp took it all in its stride. ZZ Top rocked, while the subtle, understated, yet equally successful at those powerful nuances that make Miles Davis’s trumpet play a sublime experience. 

The Accuphase E-700 is an exceptional performer. It has authority, power, dynamics, rhythmic energy, and grip while offering subtlety and inner detail where it is needed. When someone really hits a tom or snare, the E-700 conveys its impact and delights the listener with subtle insights into a delicate cymbal line or the technique and style of a skilled guitarist or sax player.

I truly enjoyed my time with the E-700. It offers superb performance at the price and you’d be very unwise not to consider it if you have around £10k burning a hole in your pocket.

Tech Talk: Nuno Vitorino on Innuos STREAM3

Innuos has specialised in the design of music streamers and servers aiming to provide the best music listening experience since 2016. However, the STREAM platform is a bold venture for Innuos, essentially replacing the company’s popular original ZEN platform. With no built-in CD drive and the option for built-in DACs and more, STREAM3 shows Innuos both retaining its server capabilities and moving into new markets for the brand.

Nuno Vitorino, the R&D Director and Co-founder of Innuos is no stranger to these Tech Talk pages. We caught up with him in the company’s factory in Portugal and asked about what it took to introduce the STREAM series.

How did STREAM come about?

The STREAM series were based on the concept of merging the previous ZEN Mk3 and PULSE series into a modular product to adapt to user needs. Some users prefer to have a dedicated music server with separate streamers, some prefer an all-in-one. Some prefer to do streaming only while others prefer to also have their own local music library. Before the STREAM, you’d use the PULSE series if you wanted to stream only and use the ZEN Mk3 if you also wanted to have your local library. Some ZEN Mk3/PULSE series had DACs and digital outputs, some did not. The storage was fixed on the ZEN Mk3 series so users had to send the unit to the factory to upgrade the storage. The STREAM series came to answer those questions. It replaced 6 models with 2 – the STREAM1 and STREAM3. All systems on the STREAM series have user-removable storage up to 8TB and modular output boards the user can choose, ranging from different digital outputs to full DACs.

When did development start on STREAM3?

The STREAM3 started being developed in 2024, making it a fairly fast development cycle. Most of the power architecture comes from the PULSE series with trickle-down developments from the ZEN Next-Gen series. There’s a new custom mainboard with a much newer processor and memory generation, with support for newer NVMe SSDs for storage. But it’s not just about consolidating technology that was bringing the best sound for the money – we wanted the STREAM series to have their own “soul”. The STREAM series, and the STREAM3 in particular, is well-suited as an elegant and simple system. Add a DAC module, connect to active speakers and you have a great-sounding Hi-Fi system without filling your living space with components. For this purpose, we also added support for a remote control, aligning the STREAM series more with a lifestyle product without compromising sound quality.

Is this a solo design or a team effort?

This is most definitely a team effort, and quite an extensive one. Even conception comes from a lot of people. While I start with an initial vision for the product, we take a lot of feedback from internal people – product specialists, developers and sales managers – as well as from the community. I always say “no one has the monopoly of good ideas.” We search for the best technology during the design phase, investigating new materials, processes and technology, some of them cutting edge. Our design stage involves CAD, Augmented Reality reviews and 3D printing for both prototypes and some production parts. We work with specialists like Sean Jacobs for power supplies and advanced vibration materials such as TONEO on our higher end models, as well as with electronics specialists who design high-precision aerospace parts. We are also completely refactoring our software and testing processes with AI. This is the result of many heads working together – it’s no wonder we have grown to almost 50 people.

What challenges do you face building STREAM3 in 2026?

The current world context is bringing considerable challenges from a supply chain perspective. Parts that used to take a week are now given two-month lead times – and even then, come in late. Because suppliers are often behind, they sometimes skip or cut short their QA processes, which means receiving defective parts that further delay production. Given we work from the single resistor all the way to mainboards, it’s a significant challenge to bring all these together. All it takes is a missing screw and the product can’t be produced! It’s a full-time job for our Procurement team.

What do you think separates STREAM3 from its rivals?

The STREAM3 is designed from the ground up as a modular system. Configure it with a PhoenixUSB Reclocker or a PhoenixI2S board and pair it with an external DAC for a high-end setup; or add a PhoenixDAC or PerformanceDAC module and connect directly to active speakers for a strikingly simple yet jaw-dropping system. Building on our experience with the ZENmini and PULSEmini, we stepped up our DAC modules significantly in response to user and dealer demand for higher performance in simpler setups. 

The PhoenixDAC uses the same high-precision OCXO clock as the PhoenixUSB; high-quality femtoclocks, a dual-mono architecture, and separate digital/analog power supplies by Dr. Sean Jacobs – all in a board-only format that reuses the streamer’s internal power supplies, making it punch well above its weight. Our top-of-the-range systems remain optimised for separate DACs when cost is no object. 

You no longer include a CD drive. Why?

Internal optical drives have been discontinued by manufacturers, making long-term serviceability unfeasible, and demand has declined significantly – an external USB drive detected automatically by Sense software delivers the same seamless experience. As for servers in a streaming world – they remain essential. Users want to consolidate libraries across multiple services, access high-res formats like DSD and DXD unavailable on streaming, and serve regions where streaming catalogues are still limited. Most importantly, audiophiles want permanent ownership of the music they love — streaming services can’t guarantee your favourite artist will always be available. With Innuos, you get the best of both worlds.

What’s Next?

We keep working hard on software for our existing products, new output modules, and some products that complement our existing music streamers and servers… stay tuned!

Innuos STREAM3

In many audio circles, particularly in the UK and Europe, Innuos ‘owns’ the server market. This harks back to the original ZEN products. These provided an affordable, ready-to-use audio server solution at a time when such devices were still quite new and somewhat intimidating for audio enthusiasts. Times have evolved, and Innuos STREAM3 recognises these changes and the challenges they present.

Innuos STREAM3 is more of a versatile, configurable, complete digital front-end platform than a typical server. You can set it up as a one-box server, a server with an integrated DAC, or a streamer that combines locally stored and online music. You can use the company’s own app, opt for Roon, stream Qobuz or Tidal natively. It’s even possible to rip your own music if you add a USB CD drive. It provides as much, or as little, of a digital front-end as you require.

The core aspect of the STREAM3’s configurability is its Digital Output Module options. At its simplest, you can run the STREAM3 without any output board, using only the USB output marked ‘DAC’ on the rear panel. Alternatively, you can fill that vacant slot with one of five different options in the Module Bay: an S/PDIF board (with optical, coaxial, and AES outputs), a Performance DAC (RCA only), a Phoenix DAC (with RCA and XLR, as we used), as well as Phoenix USB and Phoenix I2S boards for more specialised connections. You can also choose the STREAM3 with 2TB, 4TB, or 8TB of internal SSD storage. All these options are available separately or pre-installed.

Phoenix rising

The reason we chose the Phoenix DAC option is simple. It’s the one we (and, for that matter, Innuos) believe most people opt for today. As mentioned earlier, the nature of streaming and stored music is changing. Many people are abandoning the server altogether, while others want a ‘one-stop shop’ that includes a built-in DAC. 

In the STREAM3, Innuos offers a compelling sonic performance and easy usability, helping servers stay relevant. It also makes a strong case for using it as your sole digital front-end. However, if you already have infrastructure such as a DAC that you wish to keep using, that’s perfectly fine; simply choose a different module.

This is acceptable, but even the strongest argument for a product quickly diminishes when faced with poor overall performance. Fortunately, that’s not the Innuos approach. Setting aside inputs, outputs, and storage options, the STREAM3 addresses key concerns about streamed and stored music. These concerns distinguish an audio enthusiast from someone using a standard computer for their music needs.

Noise, noise… and noise

Servers are naturally noisy: processors, RAM, storage, and network interfaces all generate electrical noise. Innuos doesn’t pretend those components aren’t present but ensures their noise does not affect the output interface or pollute downstream parts. Innuos places strong emphasis on regulation stages and a power supply architecture that isolates ‘dirty’ computing rails from ‘clean’ audio rails. 

Next, Innuos focuses on transmitting audio signals. In theory, packetised data from USB or Ethernet sources should be unaffected by timing issues; however, in practice, these are not so much ‘problem solved’ as ‘problem moved’. The sharper, less spatially coherent sound of streamed music, often dismissed by CD-loving audiophiles as ‘noise’ or ‘hash’, results from this. By implementing better timing discipline throughout STREAM3, these issues are mitigated.

Theoretical?

It can be argued that these two forms of noise are more theoretical than directly heard. However, when combined, the most noticeable audible effect of using STREAM3 is the reduction in noise it provides. Lower noise isn’t just about ‘blacker backgrounds’ (though that phrase remains because it is often accurate). It also appears as more believable instrumental textures, more precise instrument decay and reverb tails, and less of that subtle ‘glaze’ that can make streaming sound impressive but emotionally distant.

If you’ve ever compared a competent budget streamer to a genuinely well-designed digital front end, you’ll recognise the pattern: initially, the cheaper unit sounds ‘detailed’. After a few hours, it begins to sound as if it’s describing music rather than producing it. A good server or streamer does less describing and more allowing you to forget it’s there. The STREAM3 is that ‘good server’; it’s not a component you just slot into any system and instantly experience a ‘wow’ moment, but spend a few minutes with it, and the end result is compelling. 

It is also a component that scales with resolution. In a modest system—say, an integrated amplifier and a capable DAC – the Innuos may appear to have ‘more smoothness’ and ‘a bit more space’. In a revealing system (high-resolution DAC, low-noise amplification, speakers capable of reproducing microdynamics), it behaviour changes: the music becomes less insistent, more continuous, and more dynamically nuanced. If the STREAM3 has a signature, it is not an obvious tonal coloration. Instead, it is a kind of reduction of insistence.

Explicit and dense

Start with something rhythmically clear but texturally rich. Massive Attack’s Mezzanine album [Virgin] serves as a prime stress test: ‘Angel’ or ‘Teardrop’ for instance; it’s about the bass line’s grip, the gradual build-up of pressure, and the layering of gritty detail without turning everything into a grey slab. Through the STREAM3, the bass doesn’t just get louder; it becomes more intelligible. The leading edge is cleaner, yes, but more importantly, the sustain is steadier—less wobble, less one-note bloom. When the track swells, the system is less likely to become harsh. You experience impact without harshness, and the sense of menace arises from dynamic control rather than overly bright treble.

Switch to voice and space. Joni Mitchell’s Blue {Reprise} is harsh on digital front ends because her voice can shift from intimate to steely depending on the chain. The STREAM3 tends to keep that steel in check without dulling the truth. Sibilants are better integrated into the harmonic envelope; you hear articulation, not harshness. And the guitar’s transients—those quick, bright picks—arrive swiftly but with body. The overall effect is that you lean in for the phrasing rather than brace for the peaks.

Arising benefits

Regarding orchestral material, the benefits arise from scaling through organisation. Large works can sound ‘big’ on almost anything; maintaining clarity while sounding big is more challenging. The STREAM3 helps to distinguish lines without turning separation into dissection. Woodwinds stay on a stable plane, strings don’t blend into a silvery sheet, and brass crescendos don’t develop a glassy overlay.

Play a well-recorded jazz trio—say, Bill Evans’ Sunday at the Village Vanguard [Riverside]—and pay attention to the drummer’s cymbal work and the piano’s decay. The STREAM3 doesn’t just reproduce the initial strike; it follows the bloom and fade with greater continuity. That makes the venue sound more realistic and the musicians more present. The bass is easier to follow not because it’s louder, but because the pitch centre is clearer and the rhythm tighter.

Ex-statement

As a former Statement user now employing a ZENith NG, I find the comparisons quite intriguing. While the ZENith NG outputs to a DAC and the built-in PhoenixDAC gives the STREAM3 a convenient advantage, in direct USB comparisons, the STREAM3 performed excellently. The more premium ZENith NG has little to worry about – its USB output sounded more natural, as well as more spacious and rhythmically precise. However, it’s quite remarkable how much the STREAM3 has advanced; if I still owned my Statement, its continued relevance would mainly be for stage width and sunk costs.

The Innuos STREAM3 must be more than just a server; it carries a significant responsibility. If it falls short, a music enthusiast might never experience the delights of locally stored music or the sonic advantages of server-curated streaming. However, by assuming both server and DAC roles (with PhoenixDAC installed), the STREAM3 convincingly demonstrates the server’s potential.

   For those familiar with what a good Innuos server can do thanks to a previous model, the STREAM3 is an obvious choice. Well, almost… you just need to figure out which combination of modules best fits your existing system. That’s all. The Innuos STREAM3 is your next system upgrade… guaranteed.
