Vienna High-End 2026, Part One

Note: We will be adding to this regularly over the next few hours. Please keep checking back for more.

It’s no secret, but the Austria Center Vienna has replaced the MOC in Munich as the venue for the annual High-End show. While not without its teething troubles, the move has been mostly well received by consumers and the audio industry.

The crowd at the start of the first public day.

The space is larger and slightly harder to navigate. This means most of the corridors are wide enough to avoid bottlenecks and allow those who want to talk business to do so away from the music playing in the room. It also reduced noise pollution from nearby exhibitors. However, it also meant that several floors of near-identical white corridors made it easy to get a little lost. I stepped out of the elevators onto the wrong floor several times and didn’t notice for a few minutes. However, as I went to a Miele store across town instead of the Melia Hotel for DALI’s off-site launch, maybe I’m not the best judge of geography.

Regardless, Manufacturers will inevitably learn from this and introduce greater signage outside their rooms.

There also probably needs to be a larger central display welcoming visitors to the event. There was a large atrium just after guests entered the show, and inside that atrium was just a Burmester-equipped S-Class Mercedes. While a great show-opener, a ‘best of’ display with samples (or high-quality mock-ups) of some of the most high-profile products at the show would make it seem more ‘show-like ‘.

No number of preliminary visits to an event can accurately determine a room’s acoustic dynamics. While many were making good sound at the ACV, I think it’s best to suspend criticism of bad sound for this year. Once again, manufacturers learn what works and what doesn’t fairly quickly, so that free pass expires for next year, but there were a couple of systems I expected to be excellent and didn’t quite cut it. I know of at least one manufacturer who completely redesigned their room at the last minute to (successfully) improve the sound quality, and Goldmund traded places with Raidho on either side of the first floor because they preferred their respective rooms. This led people to call it ‘Goldmundilocks’, but the end result worked out well for both.

The number of main rooms was reduced slightly compared to Munich. There were many smaller rooms on the top floor of ACV, but these were largely used by companies fielding smaller systems than typically seen at the High-End shows of the past. This gave rise to several nearby satellite shows, including HiFiDeluxe, all situated a few hundred metres from the main event. While each has its own organiser, they might be wise to at least work together in the same venue, rather than having four rooms in one building, four rooms in another and so on. Even with the satellite shows, there were still some notable absences, including KEF and Rockport. We hope to see them back in some form next year.

Over the next couple of weeks, we’ll bring you the best we saw and heard at Vienna.

Bowers & Wilkins

Bowers & Wilkins 800 Series Diamond D5

Bowers & Wilkins returned to show-going with the announcement of its fifth generation of the brand’s flagship 800 Series. With one stand-mount, two centre channels, three floorstanders and the 801 D5 flagship in the line, this was a celebration of the company’s 60th anniversary as well as a mighty set of loudspeakers. Retaining many of the styling cues of previous models, the 800 Series bristle with new innovations, including a new Space Frame Bracing (that bolts directly to the rear of the now-enhanced Matrix inside the cabinet) to increase internal stiffness and reduce vibration and cabinet-borne resonance. This bracing also acts as a frame to hold the new crossover mounting plate. There are also improved tuned-mass plinths, revised aluminium top plates, and grilles and drive unit motors taken from the Signature version of the previous model. New finishes are also on show, with Dark Walnut, Light Walnut and Warm White joining the portfolio. Prices start at £10,000/€10,000/$12,000 for the 805 D5 stand-mount and rise to £43,000/€50,000/$65,000 for the 801 D5.

Cambridge Audio

Cambridge Audio Evo 300

The new Evo 300 from Cambridge Audio is the brand’s most advanced streaming amplifier. This is a bold statement from a company that has been making streaming amplifiers for some time, but the 300W per channel integrated amplifier (using Hypex NCOREx Class D amp modules at its core) makes a strong musical and performance-based case. Built around a balanced preamplifier stage with separate analogue volumes for each channel, the amp builds on the performance of the company’s current top streaming integrated, the Evo 150 SE. It also features an ESS Sabre ES9038Q2M DAC and the company’s one StreamMagic Gen 4 platform, and a 7.8 in screen. This £3,499/€3,999/$3,999 integrated amplifier offers much.

 

Dan D’Agostino Master Audio Systems

Dan D’Agostino Master Audio Systems Progression Neo

Not content with announcing the Momentum Z mono power amplifiers earlier in the year, Dan D’Agostino Master Audio Systems announced several new products that utilise the Z topology designed to improve the interface between preamp and power amplifier, by carefully addressing power supply, input stage, thermal design and system monitoring. The Relentless Z Preamplifier, Relentless 800Z mono power amplifiers, and Relentless Epic 1600Z mono power amplifiers all benefit from these Z circuit design developments.

But, perhaps even more significantly, there has been an entire refresh of D’Agostino’s more attainably priced Progression series. The new Progression Neo preamp and both stereo and mono power amplifiers have a bold new styling – one that still carries much of the D’Agostino classic cues into a very ‘now’ look – but draws it’s circuitry from the higher-end Momentum and Relentless range. With a preamp featuring a JFET input stage (like the Relentless) and power amplifiers with output concepts developed for the Momentum Z mono amps, these were delivering an extremely impressive sound through a pair of Wilson Alexia Vs in Audio Reference’s outstanding demonstration space. Fed by dCS and VPI, these amps had ‘grip’ by the bucketload. Prices are still to be confirmed.

DALI

DALI VEGA all-in-one system

An all-in-one is not the first thing to consider as one of the stars of a high-end show, but stay with me. DALI’s new VEGA system includes BluOS and its own, in-house DSP. The VEGA features four soft-dome tweeters with 25mm membranes and neodymium magnets and four 110mm mid-bass drivers placed back-to-back with an ABR system. The hefty system is designed to be used on a table or a wall, and can be vertically or horizontally mounted (or even moved from one position to the other using a special rotator mount). With presets for playlists and radio stations – all accessed through the BluOS ecosystem – it’s designed as an easy way to get good sound into other parts of the home than just the man cave. The price is €3,000, and is expected to be around £2,600 and $4,500 when launched in September.

Gryphon

Gryphon Hyperion

Designed to replace the mighty Mephisto, Gryphon’s new €59,800 Hyperion power amplifier is a bold project from a bold high-end brand. Dressed in the company’s typical ‘none more black’ livery, this truly dual mono 126kg, 180W Class A amplifier runs hot, requires two 20A power inputs, and can pack a 720W Class A punch into two-ohm speaker loads. And playing LPs in a full Gryphon system, it sounds like it lives up to the reputation of the amplifier it replaces!

 

Ideon

Ideon Nous

Greek digital experts Ideon have been busy of late. Not content with developing the remarkable Axiom digital system in time for AXPONA this year, the company just announced the Nous, a complete high-end streaming and playback system. Available with or without a line-level preamplifier, the Nous differs from conventional streamer-based products by being designed as a purpose-built audiophile environment where streaming, digital processing, clock management, DAC conversion, analogue amplification, and power regulation all act as one. Its performance is said to be closer to that of the Absolute DAC from the brand. The fully balanced Nous costs $32,000 with preamp, and $29,900 as streamer alone.

Moon

 

Moon 491 streaming preamp and 461 power amplifier

 

It would have been easier for Moon to take the popular 371 integrated streaming amplifier from the Compass range and split it into two separate components. Instead, Moon listened to its better angels and went with a vastly more flexible and powerful pairing. With all the inputs and outputs you could ever need and a highly flexible MM/MC stage, the £5,950/$6,500 491 uses the more sophisticated volume control and hybrid linear/switch mode power found on the brand’s higher-end devices. Meanwhile, the £4,450/$5,000 power amplifier uses even more of the hybrid power supplies to deliver its 150W per channel. This can be driven in bridged or bi-amp mode.

While we’ve said we won’t be discussing sound too much at this show as it’s new to everyone, this system – coupled with Dynaudio’s Contour Legacy loudspeakers and Nordost Heimdall 2 cables – was a true star, with plenty of drive and energy.

 

Wadax

Wadax Studio Collection in full

2024’s Wadax Studio Player was always intended to be a part of a Studio Collection. That Collection was joined by the Studio Clock, Studio PSU and Akasa cabling system last year. At Vienna, the Wadax Studio Collection is completed by the addition of a Studio Transport and Studio DAC. As the name suggests, this includes a dedicated CD/SACD transport and a dual-mono DAC, taking full advantage of the low-noise, high-speed architecture of the Studio Player (and leveraging technologies from the mighty Atlantis by Wadax), while adding greater connectivity and flexibility to the Wadax Studio ecosystem. The DAC also marks Wadax’s first headphone-related product. Prices for the new models are set at $42,950 for the Transport and $39,500 for the DAC.

 

Karan Acoustics Master Collection POWERb MONO

Karan Acoustics’ range comprises entirely of Master Collection products today. There’s a preamplifier, phono stage, stereo and mono power amplifiers. These all stay in the entirely uncompromising, cost-no-object ’a’ range or the slightly trimmed down ‘b’ form. In this case, ‘trimmed down’ means a one-box preamp and phono stage and slightly smaller stereo and mono amps. Until now, we tested every product in the range except for the Karan Acoustics Master Collection POWERb MONO amps. This review brings a sense of closure to the review cycle.

That closure feels deeper in this review. Sadly, Milan Karan, chief designer and the man behind Karan Acoustics, died in 2024 at the age of just 58. Some time before his passing, Karan expressed a desire for the Master Collection to be his swansong. However, I don’t think anyone expected it to be his valediction. He considered these amplifiers to be the best products he knew how to make. The company continues in the capable hands of the Karan family. International recognition of Milan Karan’s crowning amplifier achievement has only increased with his passing.

One of the cleverest parts of the Master Collection range is that there is a lot of shared design. This means there are no great changes in technology – or tonal shifts – as you move between ‘a’ and ‘b’. The POWERb MONO uses the same differential circuit design found across all four amplifiers in the line-up. They all implement the very best Sanken bipolar output devices, the power supplies and their accompanying audio infrastructure have been extensively reworked. The same applies to the input (driver) stages with both high-grade Audyn and superior, proprietary Karan Acoustics capacitors being used throughout. 

Quality components

The component list of greats also includes Vishay and Roederstein resistors as well as Cardas Audio’s highest quality chassis wire. That, however, is not all. As with all Karan mono amplifiers, each ‘polarity half’ of each audio channel (ie. amplifier) has its own independent mains transformer and accompanying power supply. Which also means you need two mains cables for each amplifier. 

For the POWERa amplifiers, Karan worked with its suppliers. The companies developing completely new, much larger, more powerful, and mechanically quieter toroidal transformers. This led to a proportionally enlarged bank of power supply reservoir capacitors of equally high-grade specifications. In the process, this provides the circuits with an even greater reserve of power and current that is always ultra-quickly available. The POWERb STEREO and MONO follow suit, with only slightly reduced power delivery and capacity. Although ‘reduced’ is inaccurate for an amplifier boasting twin 2,100VA toroidal transformers and a custom 180,000µF reservoir capacitance bank. As before, speaker terminals and RCA inputs originate from WBT, while Neutrik provides the XLR input interface.

Remarkable

This amplifier’s power output is remarkable. It delivers a robust 1,200W into an eight-ohm load, with peaks reaching 1.5kW. It can even provide up to an impressive 3.6kW into a two-ohm load. Like its larger POWERa MONO counterpart, it requires two power cables per chassis. This arrangement enables the amplifiers to transmit the signal’s full bandwidth and dynamic headroom into any loudspeaker load. Meanwhile, this also allows for excellent transient speed and extremely quiet circuit operation.

Karan Acoustics Master Collection POWERb MONO rear panel

Similar to the other POWER models in the range, the Karan Acoustics Master Collection POWERb MONO features an advanced mains (line) conditioner. This conditioner addresses and eliminates unwanted DC-related by-products from our electricity supply. The amplifier includes a switch on the back panel that allows you to choose whether to hear the sound with or without the conditioner/DC filter, regardless of whether the amplifier is powered on and playing music. While there are few aspects of audio that are as contentious as the line conditioner/DC filter market, I would still like to see this offered as a separate, universal product within the Karan Acoustics product range.

Circuit resonance damping

The chassis also functions as an effective circuit resonance-damping system. Increasing the mass is the most obvious solution for achieving superior overall damping. However, the issue arises that using too much of the wrong type of metal can do more harm than good. Additionally, employing a large lump of aluminium to mass-load the amplifier may create its own source of resonance. To address both concerns, Karan Acoustics designed the main chassis as a single-piece unibody made from a solid CNC-machined block of high-grade aluminium. This serves as a heatsink for the output devices while establishing a highly non-resonant environment for the entire amplifier. This design also contributes to lowering the amplifier’s noise floor. Continuing with the impressive specifications, all 81kg (per amplifier) sits on three Critical Mass Systems CS2 1.5 supporting feet. It has proper wooden crates for shipping, too.

Externally, there is little to differentiate POWERa and POWERb designs. This MONO amplifier is slightly shorter than its bigger brother, weighs just over 20kg lighter and it has ‘POWERb’ instead of ‘POWERa’ on the rear panel.

Do well

The Karan Acoustics Master Collection POWERb MONO has several shoes to fill. As part of the ‘b’ Series, it should be resolving enough to deal with Karan’s matching LINEb preamplifier (tested in Issue 191) and shine with the company’s LINEa two-box flagship preamplifier (tested in Issue 181). It needs to stand slightly above the POWERb STEREO (tested in Issue 223). It also needs to reach, yet not exceed the levels of the mighty POWERa MONO (tested in Issue 203). And above all this, it needs to stand on its own as a very high-grade power amplifier. This demand is for those who might not have caught the Karan bug, or are upgrading from Karan’s previous KA line. So, it needs to be better than the likes of the KA-M1200 (tested back in Issue 50) and on a par with the likes of Constellation, Gryphon, and Vitus.

If that sounds like a big ask, you haven’t been keeping up with Karan’s Master Collection. These are the sort of power amplifiers that answer questions before they are asked. It gives effortless power with way more in the tank. Also, given the almost limitless power of the POWERa MONO, the POWERb MONO is not far behind, the POWERa MONO’s reserves in the tank are more than enough for all except the most challenging of loudspeakers. In fact, there’s a good case to make that the POWERa MONO is gilding the lily in the majority of systems today.

More than just power

The Karan sound is one of effortlessness in more than just power delivery. Every Karan amplifier has a sound that is as easy on the ear as it is detailed and informative. It’s supremely dynamic and is possessed of stentorian bass that controls your loudspeakers with absolute authority. However, that precision and power does not come at the expense of a roller-coaster ride through music. The Karan Acoustics Master Collection POWERb MONO never bombards the listener with sound.

It’s presentation is as refined as it is effortless. The high-frequency energy and zing is there, but only when called for. The rest of the playing time, the amplifier simply swings. There’s nothing out of place, in spatial, dynamic and detail terms. The amp’s sense of rhythm is good for a large power amplifier; not ‘pacey’ and ‘lithe’ in the way British ‘PRaT’ obsessed designs excel, more of a sense of complete musical control.

Karan’s POWERb MONO’s main characteristic is to play the music it’s fed without favouritism. That sounds over-simplistic, but it’s at the heart of what this amplifier delivers. I went back and looked at my notes and reviews of other Karan power amplifiers, and this is a strong family trait. You get the whole story; whatever signal is sent to the amplifier is reproduced with as little as possible between preamplifier and loudspeakers.

Straight wire with gain

This has long been a goal of power amplifiers – Peter Walker of Quad coined the phrase ‘a straight wire with gain’ to describe the ultimate in amplifier performance – but we are still far from achieving that aim. The Karan amps get closer than most, especially if you prioritise detail, dynamics, soundstaging and sheer control over the loudspeakers as important considerations. And yet, beyond this, the Karan amplifiers have a sense of refined musicality to their performance, which makes you focus on the ‘end’ (the music itself) rather than ‘the means whereby’ (the equipment).

I’ve found with Karan equipment that despite the call to use numerous musical examples to highlight what the amplifier can do, everything is encapsulated in a single recording. This is a sign of true quality, as all the aspects of an amplifier are presented evenly and equally at the outset. While further listening only reinforces that initial opinion, the strength of its balance of sonic properties is telling from the outset.

Everything, everywhere, all at once

In fairness, Karan Acoustics is not alone in this ‘Everything, Everywhere, All At Once’ approach (great movie, by the way!). However, most amps that have such an even spread of qualities come with a considerably more lofty price tag.

The track that showcased what the Karan Acoustics Master Collection POWERb MONO does so well was perhaps the simplest. It was The Unthanks (and Niopha Keegan) singing ‘Bread and Roses’ [Diversions Vol 5 – Live and Unaccompanied, Rabble Rouser]. You get a sense of a small hall with a low ceiling, the intimacy of the recording, and the pitch-perfect articulation of their voices. You also get the energy and passion of their voices, and the gentle, respectful interaction between singers and audience. Then, there is the dynamic range of a capella singing. Finally, you get a sensational coherence across the range and the feeling of being there in the place thanks to powerful solidity and speaker control.

Not a foot wrong

Accepting that those Critical Mass Systems feet take a few days to transform the sound, the Karan Acoustics Master Collection POWERb MONO doesn’t put a foot wrong. Yes, arguably balanced outperforms single-ended input, but that’s more to do with XLRs taking full advantage of the circuit design. In fairness, single-ended is no slouch, so if your preamp is single-ended only, don’t count these amps out just yet. In fact, my only gripe is about the name; Karan Acoustics Master Collection POWERb MONO is a real mouthful. If your biggest criticism is the length of the name, you know the amp is good.

Good enough that I’d say the Karan Acoustics Master Collection POWERb MONO is among the high-end’s best balancing acts. It perfectly balances sheer power output and the quality of that power. If you don’t need the pile-driving power of the POWERa MONO, and love that refined effortlessness that these amplifiers bring, it’s hard to find something better this side of six figures.

Karan Acoustics’ Master Collection range is a true testament to the late Milan Karan’s skills as an amplifier designer. Whether the last designs from his drawing board are the last models Karan Acoustics make is a moot point. ‘What have you done for me lately?’ drives the pace of most product life cycles. But the Karan Acoustics Master Collection POWERb MONO is built for the long game; nothing is going to outperform this any time soon.

Hegel D50

Hegel is no stranger to this magazine. The company garners great respect for its digital expertise. DACs have played a central role in many of Hegel’s products over the years, whether in CD players, amplifiers, or standalone DACs. The built-in DAC in many Hegel amplifiers often outperforms the DACs in other digital sources from its many peers and rivals. Therefore, when a company with this extensive history launches a new flagship DAC like the Hegel D50, it’s worth taking note. 

Features

The Hegel D50 is a versatile and adaptable unit, albeit not overloaded with inputs. If you require a DAC with a back panel resembling a server farm’s patch board, then you might need to look elsewhere. However, it is as well-equipped as most will need. The available digital inputs are more than sufficient for most needs: one each of AES/EBU, BNC, RCA coaxial, and USB, plus a pair of Toslink/EIAJ optical inputs, feeding either balanced or unbalanced analogue outputs. The D50 also offers several user-configurable features, including input sensing, automatic standby, and display dimming. The familiar, minimalist Hegel remote control can operate functions and navigate menus, but a manual option is available via three discreetly hidden buttons beneath the front display.

It’s clear from the outset that Hegel intends the D50 to showcase everything it has learned about digital technology, and in doing so, it stands on the shoulders of the commendable products that came before it. However, the Hegel D50 also introduces some new and intriguing features of its own, which distinguish it. This review followed quickly after the workup for issue 244, the Audio Essentials issue. One of the emerging themes of system setup is the importance of paying proper attention to reducing and managing electromagnetic noise. 

Noise annoys

Hegel has taken extensive measures in this regard within the D50, designing the internal power management to contain and reduce internally generated EM noise. All the power supplies are analogue—no switch-mode supplies here—using two separate low-noise toroidal transformers, carefully positioned and shielded to keep the noisy digital and standby functions apart from the sensitive digital and analogue components. However, Hegel also tackles noise entering the system from external sources, especially the mains power, which also offers interesting side benefits for the rest of the system. 

Hegel D50 rear panel

The incoming mains power is filtered to remove electromagnetic interference (EMI), and, interestingly, this filtering can also affect other equipment connected to the same power circuit. When the unit arrived, the UK distributor and I set up the D50 on my MusicWorks rack, but we had not yet connected it. We played a CD track, and only then did we plug the D50 into my Nordost QB6 power block. Playing the same track again, there was a noticeable improvement in spaciousness and dynamic expression—precisely the kind of effect I’ve heard and associate with a reduction in mains-borne EM noise. 

Improves before switch on

Remarkably, here we have a DAC that improves your system’s sound even before you switch it on, let alone use it to decode your music. In its quest to reduce EM noise, Hegel has also focused carefully on circuit board design and layout. The board for the single ESS 9039Q2M Sabre DAC chip is positioned above the other electronics, reducing noise and interference, shortening signal paths, and allowing it to be placed as close as possible to the master clock.

Additionally, the D50 features three master clocks: one for the S/PDIF feed and two for USB — one for 44.1 kHz and another for 48 kHz sample rates — strategically positioned to minimise noise and optimise timing data. There is also further innovation in how incoming digital signals are processed, enabling better handling of both weak and strong signals, free from jitter and time delays. It reads like a masterclass in tackling the menace of EM noise.

The distributor also brought a partnering Hegel H400 amplifier, which features its own excellent internal DAC and streamer, making it a one-box streaming system. However, an interesting feature of recent Hegel amps is that they can bypass the internal DAC via a ‘DAC loop’ function to a BNC digital output. Using this to feed the D50, then taking the analogue output from the D50 back into the H400’s inputs, resulted in a significant improvement in the H400’s performance, making the D50 a viable upgrade option for any H400 user. I spent part of this review with the system configured this way, but my Accuphase CD player and amplifier did most of the work, connected via an optical cable to the D50.

Space, finally in front of my ears

Musically, the first impression is of a clear, spacious, highly resolved, and detailed presentation. That’s a good start, and it just continues from there. Michael Torke’s suite Miami Grands [Ecstatic Records] is scored for ten pianos. That’s not a typo. The music is at times dense, lyrical, and, above all, beautiful, and often reminds you that the piano is a percussion instrument. The D50 provides a substantial performance space (you wouldn’t fit ten pianos in a salon) with a clear sense of the acoustic environment. It’s possible to discern, if not all ten, then certainly quite a few of the instruments at any given time, to the extent that different instruments’ timbres and even performers’ playing techniques are noticeable. 

There is also space between and around the instruments, making their contributions easy to distinguish at will. ‘South Beach, midnight’ is rhythmically assertive, with interleaved and interwoven threads, and the potential to sound like a complete mess in inexperienced hands. Here, it is simply and undeniably compelling and captivating. ‘Everglades, under the stars’ twinkles softly but percussively, with a clear attack on the notes, tightly timed edges, and a well-developed note envelope. The colours and timbres of the individual instruments contribute to the diverse landscape the piece evokes. There is skill in how the D50 resolves and presents complex, layered, and nuanced music without dissecting or deconstructing it. It makes experiencing it naturally easier, closer to how we do at a live performance; no strain, no subconscious struggle to suspend disbelief. 

A third of a millennium

Backtracking a third of a millennium for a spot of Purcell, ‘When I am Laid in Earth’ from Dido and Aeneas [English Chamber Orch/Leppard, Warner Classics apex], there’s tension right from the opening bass line in the strings, the better to melt into pathos as the contralto sings; her fluid phrasing, subtle inflections and emphases are utterly impeccable but if the system doesn’t deliver, that pathos quickly dissolves into schmaltz. Not here. Yet again, this is a riveting and very affecting performance. 

Hegel D50 in situ

From the sublime to, well, a different kind of sublime: Sting, live, performing ‘Roxanne’ from All This Time [A&M]. Once again, there is a strong sense of the spatial arrangement, not only of the band and soloists but also of the audience. When they start clapping in time as the groove kicks in, it becomes a clear part of the event, not just something absorbed into the overall rhythm and percussion. 

The tabla on ‘Peshwari’ from Andy Sheppard’s Learning to Wave [Provocateur] is tactile, textured, and melodious, contrasting beautifully with Sheppard’s lilting, lyrical saxophone phrases and John Parricelli’s gentle guitar counter-melodies. It’s a genuine performance, and the musicianship and skill are unexpectedly more apparent when they don’t call attention to themselves. None of this detail is flaunted; it’s not cynically designed to impress in a quick, ten-minute A/B demo. It simply exists within the music.

Robust

A digital signal is inherently robust, but converting it to an analogue signal, especially for music, presents challenges due to the noisy electromagnetic environment in which it often operates. Much depends on the quality of the analogue components, the power supplies, and the internal housekeeping. Hegel has gone to great lengths to protect and maintain that process, resulting in crystal-clear precision. 

Sometimes a product provides all the information you could want, but, like a photorealistic portrait, you may feel you’re appreciating the talent and skill yet missing the art. The market is full of products that offer ‘transparency’ and all sorts of hyper-detailed presentations, but the Hegel pulls off that trick of presenting detail in the service of the music. The Hegel D50 offers steady competence and natural musicality that could embarrass some much more expensive rivals.

Melco S1

Melco – the Japanese maker of some excellent servers – is also no slouch when producing network infrastructure products. That’s hardly surprising given that the computer peripheral giant Buffalo Technology is a part of the same company. And having Buffalo on the same team means Melco’s audio-grade switches have credibility beyond that of a company modifying third-party network products. None of this prepares you for the Melco S1 network switch. Nevertheless, it remains impressive.

Let’s be honest: Part of that unpreparedness is related to the price tag. The very concept of an audio-grade network switch is comparatively new. Some still use a low-cost Netgear or TP-Link switch to connect their streamers to their servers and the outside world. The Melco S1 is about 300 times as expensive as those mainstream devices. So, the S1 has some pretty big and expensive shoes to fill.

Not the first

The Melco S1 is not the company’s first switch. It draws on lessons learned from making the company’s S100 switch and its matching S10 linear power supply. However, with the S1, the audio-only dedication and precision shift into higher gear. The S1 distils the two-box technology of the S100 and its external S10 power supply into a single chassis. However, that alone would not make a world-class audio switch. That single chassis looks like the company’s N1 server without a central display. It has the exact dimensions of 440x82x353mm and weighs 14kg, like the server. 

Melco’s S1 has 11 network connections in total. However, the first four are SFP+ (Small Form Pluggable) connectors, which replace conventional copper Ethernet cabling with fibre-optic connections. While you can use SFP-RJ45 converter modules in any product with an Ethernet connection, having native SFP+ fibre optic connections, such as in Melco’s N1 and N5 servers, is a boon. It helps keep noise levels extremely low.

Seven ports

The seven RJ45 ports are professional-grade Neutrik connectors, typically found in recording studios (and top-end Melco servers). Behind those sockets sits a dedicated, audio-optimised internal NDK clock and a capacitor bank to ensure exceptionally smooth power delivery. There is also a BNC input for an external clock and a USB for charging only.

These 11 connections have an unprecedented degree of user control. You can select the speed of each Ethernet link or turn it off altogether by pressing its corresponding front-panel button. The colour of the illumination surrounding that front panel button determines the status of each link. For the SFP+ links, you can choose 10 Gbps or 1 Gbps. The RJ45 can run at 1 Gbps, 100 Mbps, or 10 Mbps. These lower speeds invite the question, ‘Why bother? Isn’t faster always better?’ In listening tests, many prefer the performance of a system running at lower bit rates. These rates introduce less radio-frequency noise. Once again, SFP+ has an edge here. Yet the Melco S1 offers greater flexibility in connections throughout the entire Local Area Network.

Extreme thoroughness

The level of thoroughness is extreme. There is a tiny potential risk of noise from the two ‘link’ and ‘activity’ LEDs accompanying an RJ45 socket. You can turn off these LEDs by pressing from the rear panel. And if you go deep, determining the optimal use of LEDs for each active RJ45 socket is an audio obsessive’s dream. In truth, whether the LEDs were ‘on’ or ‘off’ was too nuanced for me. However, you do you!

This review must test the quality of SFP+ and RJ45. However, you need to resolve an important side quest first: Which is better, RJ45 or SFP+? There is no simple answer, as it depends on your hardware. For example, those using Network Attached Storage will probably find staying with RJ45 the best—and best-sounding—option. Meanwhile, those with RJ45 servers and streamers with SFP-RJ45 adaptors in place get mixed results. For those with Melco N1 servers and similarly native SFP+ connected streamers (such as the HiFi Rose RS130 Network Transport), why are you even considering RJ45? If RJ45 through the S1 reduces noise to as low as it gets for Ethernet, SFP+ is the noise-free option. Indeed, this comes across as a full ‘rounding and grounding’ of the sound. 

Hard to return

It’s odd; you don’t necessarily notice this ‘rounding and grounding’ until you hear it. And then it’s hard to return to a copper-based Ethernet. Music is free from that background ‘electronicky’ hash that comes across as slight grain and a filling in of ‘the spaces between the notes.’ Naturally, this comes over best with piano, where the individual notes seem to emerge organically. They emerge with a sense of solidity and ‘thereness’ that is outstanding. This doesn&rsquo;t need to be some dusty classical piece or jazz noodling. For example, the opening bars to ‘Laura’ by Bat For Lashes [The Haunted Man, Parlophone] are a great example. 

Don’t downplay the quality of the RJ45 performance, though. While many S1 switches will likely accompany Melco N1 and N5 servers, where SFP+ is usually the best option, the RJ45 connections are equally top-notch. As before, the S1 grants you closer access to the music. It eliminates a significant proportion of what we dismiss as negative in ‘digital’ or especially ‘streaming’ sound.

The right contradictions

The S1 doesn’t change the fundamentals of a recording, but it does give its sound effortless finesse and sophistication. That might sound contradictory; something as harsh and angular as Miss Kittin’s ‘Frank Sinatra’ [First Album, International DeeJay Gigolo] shouldn’t benefit from a more refined presentation. However, that precision and clean, undistorted delivery even benefits this slice of trashy electroclash. It makes the cheap-sounding synth sounds better delineated, with razor-sharp attack and decay. Staying with the ‘seemingly contradictory’, the S1 makes that fatiguing music sound less fatiguing, without undermining it. Of course, once you move to something more audiophile-adjacent (Rachmaninoff: Symphonic Dances, Zinman, Baltimore SO, Telarc), the S1 frees up the music’s dynamic range. It also improves staging and detail. 

Dialling in the optimum link speed is the icing on the cake. Yet the Melco S1 is one hell of a cake!

There’s a three-question story arc to the Melco S1; you begin by asking, “How can they justify that much for a switch?” After listening, you ask yourself, “How can a switch make that big a difference?” Shortly after, you ask, “Which credit cards do you prefer?” The Melco S1 network switch is a remarkable achievement. It shows us how much musical information can be lost to the network infrastructure. It also shows how effortless our music can sound when you address that infrastructure correctly.

Rethinking the Long Tonearm: Wand Introduces 12in Dark-Light Tonearm at Vienna High End 2026

Nelson, New Zealand — 4 June 2026 — Wand is set to unveil its new 12-inch Dark-Light tonearm at Vienna High End 2026, building on the acclaimed 10-inch model introduced at Munich High End 2025. Designed for listeners who value both design purity and musical engagement, the 12-inch Dark-Light advances Wand’s core philosophy: reducing noise and distortion while preserving the musical flow.

Rethinking the Long Tonearm

While 12-inch tonearms are not uncommon in high-end analogue, Wand’s approach challenges a long-standing compromise. Increasing length typically reduces tracking distortion, but it also tends to increase susceptibility to flex and resonance. Designer Simon Brown argues that this trade-off is widely accepted—yet rarely addressed directly. With the Dark-Light, the intent was not simply to make a longer arm, but to create one that becomes structurally more stable as it grows in length—an approach he believes is unusual, and possibly unique, among 12-inch designs.

Structure That Improves With Length

The key lies in Wand’s Musical Taper™. As the arm length increases, so too does the diameter of the tube toward the pivot, producing greater stiffness rather than the expected loss of rigidity. The larger rear section also enables a greater internal brass mass, lowering the centre of gravity and aiding what Brown describes as a “virtual earth” for vibrational energy. Referred to—only half jokingly—as “BLOB technology” (Big Lump Of Brass), this internal mass acts as a termination point for energy travelling down the arm, rather than allowing it to reflect or accumulate. The result is a tonearm that grows more structurally stable with length, something users consistently associate with a sense of ease, clarity, and composure in listening.

Engineering That Serves the Music

At the scale of vinyl playback, precision is everything. Groove modulations range from around 0.1mm down to microscopic signals approaching the wavelength of visible light, yet the tonearm must remain stable while tracking record warps many orders of magnitude larger. This dual requirement underpins the Dark-Light design: stability combined with free, unimpeded movement.

Central to this is the ZeroPoint™ bearing, a diamond-on-carbide interface that maintains consistent contact under load. The natural drag of the stylus creates a force vector that biases the contact point, aligning it broadly with the stylus cantilever. This reduces microscopic instability and improving both detail retrieval and bass clarity. Supporting this, the Side-Glide™ bearing provides gentle lateral stabilisation, ensuring controlled motion without introducing additional friction.

Simon Brown reports that users consistently describe a freer, more unconstrained presentation, with strong rhythmic stability and a notably quiet background that allows fine detail and spatial information to emerge clearly. Others highlight refinement, clarity, and a convincing sense of acoustic space, reflecting the arm’s ability to manage vibration and preserve low-level information.

Form Meets Function

Beyond performance gains, the extended 12-inch geometry brings a refined visual balance. The proportions enhance both tracking performance and aesthetic integration with modern high-end turntables.

Availability and Price:

The Wand 12-inch Dark-Light tonearm is available now, with a retail price of €8,900.

The Wand Dark-Light 12in tonearm can be heard at Vienna High End in Halle 5, S15.

Smetana: Má Vlast

No conductor was more closely associated with Má Vlast than Rafael Kubelik. Smetana, in his cycle of six Symphonic Poems, pays homage to his Czech homeland. Kubelik – a Czech Émigré who left his country in 1948 – made five complete recordings of the work between 1952 and 1990.

His Boston account was taped in March 1971, and released on two LPs in September that same year. It was Kubelik’s third recording of the work, and his first meeting on record with the Boston Symphony. It also seems to have been the BSO’s first and only recording of the piece.  

Symphony Hall, Boston, has exceptional acoustics that produce a sound with wonderful tonal richness. Heinz Wildhagen, Kubelik’s regular Tonmeister, often used just a couple of Neumann stereo mics, rather than a complex multi-mic set-up. Certainly, spatial perspectives sound very natural in this recording.

Kubelik’s Má Vlast was recorded on four-track 1/2in tape – two tracks for the main front channels, and two tracks for ambience. For this new 180g vinyl reissue, DG have gone back to the original four-track master. However, to use this tape to cut LPs, they had to modify their four-track tape deck by adding a preview head which warns the disc cutter of loud/quiet passages ahead so it can vary the pitch of the grooves. 

This enabled DG to avoid further copying that would erode the pristine quality of the original tapes, and mix the four tracks keeping everything in the analogue domain. As a result, the sound is cleaner and better focused than ever before, with greater clarity and transparency.

The ambience is more convincingly portrayed, and you sense the hall’s air and space better. Overall, the reproduction is quite a bit fresher, with more fine detail, better instrumental delineation, and a firmer, deeper, better-defined bass. 

Among all the many recordings of Smetana’s Má Vlast, Kubelik’s Boston Symphony version has long been my favourite. A great performance with lovely sound, I played it many times before hearing another version.

In Kubelik’s DG recording, reverberation from the loud passage carries on over the quiet part for a second or so – something that wouldn’t happen in a drier acoustic. The effect is thrilling; a brief magical moment that has no equal in any other recording.

Also, in the same movement, the passage depicting water nymphs in the moonlight (around 5m 35s) is stunningly evoked by the sound’s wonderful depth and spaciousness. Has it ever sounded more enchanting? It makes other versions seem slightly prosaic and matter-of-fact…

The whole performance is by turns bracing and invigorating – lyrical and poetic. You sense the BSO were delighted by Kubelik’s inspired direction, and enthralled by a marvellous score they hadn’t encountered before.

This reissue includes the original set’s music notes, but not the history essay on the BSO. However, as a bonus, you get reproductions of DG’s original session sheets, plus a picture of the tape box. The new LPs are superbly cut, and sound impressively clean and detailed, with quiet surfaces. 

Climaxes peaks around 4dB higher than the original LPs, with noticeably greater presence and immediacy. Hiss levels are low due to DG having recently started to use Dolby A noise reduction – the original A301 processor – at the time of recording.  

Sides one and three are quite short – around 15m and 12m respectively. Side two lasts about 21m, with side four around 26m. On sides two and four the grooves are cut to within 4 – 6mm of the label – Yikes! Fortunately, the sound remains clean right to the end of side…  

The original 1971 boxed set of Má Vlast and subsequent reissues turn up quite frequently on the used LP market. But none of the earlier issues sounds anywhere as good as this new 180g remastered LP from DG’s The Original Source series. It really is outstanding

McIntosh DS200

Just as you recognise a giraffe when you see one, it’s difficult to confuse the work of McIntosh Laboratory, Inc of Binghamton, NY, with that of any other hi-fi brand. In fact, the company established its industrial design vocabulary quite some time ago. The lack of updates since then suggests it does not consider it broken.

So, despite this DS200 network streamer-cum-DAC being a modern device, it arrives in the same guise that every other McIntosh product has done for the last 50 years and more. Whether the design is appealing is very much down to the individual beholder’s taste.

Spec effectiveness

What is somewhat less subjective is the DS200 specification’s effectiveness. For instance, consider the “audiophile grade” quad-balanced, eight-channel DAC that McIntosh has fitted. It&rsquo;s suitable for resolutions up to 32bit/384kHz, DSD512, and DXD384kHz. It has been chosen, according to the company, due to its “huge dynamic range’ and “low distortion”.

Getting digital audio information to that impressive DAC can be done in several ways. Physical connectivity includes a pair of digital coaxial inputs (supporting up to 24-bit/192kHz resolution) and a pair of digital optical inputs (with the same resolution). There’s a balanced AES/EBU input (24bit/192kHz once again) and a USB-B that can extend all the way to 32bit/384kHz, DSD512 and DXD384kHz. An HDMI ARC socket allows your television to become part of your system. There’s also a proprietary McIntosh MCT connection – it enables the company’s CD/SACD transports to bypass the limitation that SACD is not preferred for S/PDIF output. Finally, an Ethernet socket provides robust network connectivity.

The wireless equivalents extend to Bluetooth 5.0 with aptX HD codec compatibility and dual-band Wi-Fi. A Wi-Fi or Ethernet connection to your router enables the DS200 to function with Apple AirPlay, Google Cast, Spotify Connect, Qobuz Connect and TIDAL Connect. Furthermore, the McIntosh is not only Roon Ready but also Roon Tested.

Put simply, it does the lot!

Outputs

Retrieving the audio once the DAC has completed its function can be done using a pair of unbalanced RCA sockets or a pair of balanced XLR sockets. It’s the (admittedly predictable) presence of these analogue outputs that makes me ponder why there are no analogue inputs. Both sets of analogue outputs can be configured for fixed or variable gain. This means the DS200 is poised to operate as a pre-amplifier alongside a power amp. However, it is not a full-system preamp, and is only for digital sources.

McIntosh Labs DS200 Streaming DAC-01

As for the usual McIntosh-isms of glowing green Gothic script, bright blue display, and black glass fascia, it is very much business as usual – and given the enduring success of McIntosh, ‘business is usual’ is precisely what people want. Even the fact that the glass faceplate collects fingerprints with a zeal more readily associated with a crime scene investigator could be viewed positively by McIntosh users, as it gives them an excuse to make their DS200 even shinier.

Control buttons cover the major functions like ‘power on/off’, ‘Bluetooth pairing’, and various playback controls—they operate with a pleasing positivity, much like the little remote control handset provided, which duplicates many of these functions. However, the turn/push controls, one on either side of the central display, managing volume level, input selection, and access to the menus, do not share that positive feel.

The third option

Then, there is the display. We live in a world where network audio streamers at virtually every price point either lack a display altogether or feature a bright, crisply rendered, and colourful display for album artwork and other elements. McIntosh, however, has decided there’s a third option. The DS200 is equipped with a dot-matrix display, which might seem ‘retro’ but once again is part of McIntosh’s ‘kerb appeal’.

With the DS200 connected via its unbalanced RCAs to a Naim Uniti Star serving as an amplifier and a pair of Bowers & Wilkins 702 S3 Signature floorstanders at the end of the chain, it’s not difficult to overlook the concerns regarding the perceived value of the aesthetics and instead focus on the exceptional quality of the sound this streamer produces. Whether streaming high-resolution content from network-attached storage, enjoying the best TIDAL Connect has to offer, or even using Bluetooth with the aptX HD codec, the McIntosh provides one of the most complete and thoroughly satisfying ways to access digital audio content that this kind of investment can procure.  

Switch between a 24-bit/192 kHz FLAC file of Bruckner’s Symphony No.9 recorded by the Pittsburgh Symphony Orchestra under Manfred Honeck [Reference Recordings] and a 24-bit/96 kHz FLAC file of Lite Spots by Kaytranada [XL], and you’ll learn almost everything there is to learn about the way the DS200 goes about things. The sound it produces is quite strongly at odds with its unrefined appearance.

Deftly naturalistic

In every circumstance, the DS200 is deftly naturalistic, maintains an utterly convincing tonal balance, and has a similarly judicious frequency response. From the profoundly deep bass to the bright and substantial treble, the McIntosh offers an even-handed listening experience. The ability to extract a significant amount of detail from recordings is a definite advantage. The DS200 maintains a well-balanced overall picture while keeping a vigilant eye on the most transient, minor, and tangential details. If the information is available to be revealed, it will undoubtedly be, along with the appropriate weighting and context. This fine detail retrieval only serves to enhance the overall recording; it is never the focal point.

The significant dynamic shifts so beloved of a massed symphony orchestra are described in full and conveyed with the sort of casual authority that denotes effectively limitless headroom. The more nuanced dynamics of harmonic variation that the same orchestra indulges in are handled with similar command. There’s a latent potency to the McIntosh that is even more effective because it’s no shouter—only large swings in intensity or outright attack prompt the DS200 to engage the afterburners. Yet it doesn’t lack subtlety—there’s a nimbleness and lightness of touch that stand in contrast to the machine’s brooding presence.  

Having said that, there’s no denying the DS200’s considerable low-frequency presence, nor its ability to deliver an implacable force when a recording demands it. It addresses bass information with precise positivity and pays just as much attention to decay, ensuring that rhythmic expression remains coherent and confident. Above, there’s eloquence in the midrange reproduction, along with an abundance of detail that reveals a singer’s character and technique. At the top end, the McIntosh achieves an endlessly pleasing balance between brilliance and substance at the onset of treble sounds, expertly controlling their decay.

Our main weapon is spaciousness

All of this takes place on a soundstage that is spacious and reasonably deep, almost fanatically defined, and provides ample elbow room for every member of this orchestra I keep referencing to perform their part unhindered by the instrumentalist next to them. This organisation and separation do not come at the expense of unity, however – the DS200 possesses the happy knack of offering a genuine sense of togetherness, of singularity, to recordings. The sense of performance is always strong. 

McIntosh products have a distinct set of design criteria that sets them apart from the audio zeitgeist. And the DS200 meets those criteria perfectly. But more importantly, if the sound of your digital audio content is paramount, this network player truly demands to be heard.

Chord Electronics Alto

The Chord Electronics Alto occupies that dimly lit nether region between the Pro Audio and Domestic Hi-Fi realms. It is designed as a headphone amplifier for studio use. Moreover, it can also drive studio monitors. The Alto features banana plugs on the rear panel and delivers 50 watts per channel into a four-ohm load. It also delivers 25 watts into an eight-ohm load. Additionally, it caters to audiophiles seeking to achieve the best possible results from their headphones. 

The technology in the Alto is a simplified version of that found in Chord’s Ultima Range of power and pre-amps. They utilise the same dual feed-forward error correction and ultra-high frequency switching power supplies. This technology originated from a paper written by Malcolm Hawksford at the University of Essex. Bob Cordell developed it at Bell Labs, with the responsibility being passed to Chord Electronics. 

Essentially, Ultima uses two additional amplifier circuits to monitor and correct the difference between the output of the reference input. Both inputs are fed to the MOSFETs, and the output of the power MOSFETs is also considered. If there is a difference between the two, the circuit adds a “difference signal” to the input of the MOSFETs to correct the error. This is then returned as part of the amplifier’s global feedback.

Uncompromising

It is an uncompromising approach to making an amplifier. However, Chord’s founder, John Franks, came from an avionics background (Raytheon, AT&T and Marconi), where exacting standards are crucial to safety. Therefore, ‘uncompromising’ has long been integral to Chord Electronics’ fundamental product design ethos.

I am aware of a few studios that use the Chord DAVE as a DAC. However, as a regular user of the DAVE, I must admit that the built-in headphone amplifier seems somewhat less impressive than the DAC section. Thus, the Alto serves as a great companion for the DAVE in terms of headphones. It is also useful for any other DAC, while providing a studio with a high-quality power amplifier for small to medium-sized studio monitors. With dimensions roughly equivalent to an A5 piece of paper (20 x 5.7 x 21.5cm WxHxD), it qualifies for the ‘portable’ category. Moreover, the Alto enables a recording engineer to master ‘on the fly’ and allows a home user to achieve excellent sound from a DAC alongside this headphone amplifier. 

Socket set

On the front panel, the Alto features four different headphone sockets: a 3.5mm jack, two 6.35mm sockets, and – a new addition for Chord – a 4.4mm Pentaconn connection for balanced high-end headphones. However, the Alto itself is not a balanced design, so the Pentaconn connection is pseudo-balanced. The rear panel features balanced XLR outputs. These can connect to a power amplifier or additional Alto headphone amps in ‘joint output mode’. However, you cannot drive headphones and speakers simultaneously. 

A robust 12-volt, 12.5-amp switch-mode external power supply powers the unit. It also features a high-quality metal remote control unit that provides general functionality.

I am a great fan of what Chord have been doing over the last few decades. The company’s contribution to DAC technology puts the brand right to the top of world-leaders in the field. The Alto is a product which sits comfortably with what Chord has already achieved. It is a useful adjunct to someone hoping to squeeze out some extra performance from their existing Chord DAC.

Sound quality

I used the Alto in my current system. This system includes a dCS Bartók DAC, a classic Naim Audio NAT01 tuner, a Townshend Allegri Reference preamplifier, a VAC Signature 200 iQ power amplifier, and Bowers & Wilkins 802 D4 loudspeakers. It also features a pair of Sennheiser HD800 headphones, which are my go-to models.

First impressions of listening to the Naim Tuner on live Radio 3 through the Alto with Sennheiser headphones yield an immaculate, punchy, and dynamic sound. The results are more detailed than I am used to. There is a distinct hint of Pro-Audio influence. It’s not a valve-family sound; it’s close to the polar opposite – taut and gritty in the best sense. 

I make recordings of the concerts in which I participate, and I find that live un-tampered (unmastered) recordings highlight the differences between equipment to a greater extent than mastered ‘finished’ recordings. Consequently, using the Alto has been a significant revelation for these recordings. 

Beyond the usual

I can discern a level of detail far beyond my usual fare, which makes the mastering process considerably more straightforward. There is greater texture to instruments and more weight to the sound. Furthermore, there is a sense of being closer to the action. It is not difficult to understand why the Alto has been such a hit among the recording community. It is truly transparent and provides a recording engineer exactly what they need to develop the recording.

Using the Alto with the Sennheiser headphones—wired with the balanced connection that the Alto provides—and listening to Tears of Joy by Antonio Forcione on the Naim Label results in a truly immersive and rhythmically etched rendition. The textures of the guitar and cello are both highly detailed and beautifully presented in space. Indeed, I don’t think I’ve heard the Sennheiser’s sound better. There is genuine layering to the sound. Moreover, the timing and pace are immaculate and brimming with energy. As a headphone amplifier, this is a win!

Preamp alter ego

Turning now to the Alto’s alter ego, I must emphasise that the Alto driving my B&W 802d4 produces some remarkable results. First up, an old favourite—Mozart’s Rondo for Piano and Orchestra K382, performed by Barenboim and the Berlin Philharmonic, yields noteworthy outcomes. The presentation possesses energy and vitality and brims with detail. In addition, the timbre of the orchestra is distinct and precise. The solid-state onboard amplifiers excel and sound like amplifiers I have reviewed that cost many multiples of the Chord Electronics Alto’s price. 

There is a smoothness to the sound; the piano positively glows and resembles a Steinway nearby. The transients are quick, and the strings display a genuine weight that I do not expect from a 50-Watt amplifier. There is a slight reduction in front-to-back depth compared to my VAC amplification. However, given its price, it offers significant value for money! The frequency response appears even to me; I feel confident that I could record and master with the Alto driving a pair of studio monitors based on what I am hearing.

Next up is something more bombastic: Andris Nelson and Shostakovich’s First Symphony, performed by the Boston Symphony Orchestra on Deutsche Grammophon. This was the composer’s graduation piece from college, written in 1924-5 when he was just 19. It features a wide range of woodwind solos and includes music he would later reuse in his celebrated 8th Quartet. The Alto rolls up its sleeves and truly demonstrates how accurately it can portray woodwind colour. When things heat up, it shows just how tightly and realistically low frequencies emerge as the bass drum kicks in. 

Taut weight

There is no shortage of string weight with this amplifier, which is quite an achievement. The brass sounds taut, and the double basses are more credible than what most valve amps can manage. The only two factors differentiating the Alto from products ten times the price are the space between the players and the front-to-back depth, along with the ultimate ‘slam’. For everything else, it’s all there.
I haven’t heard the more illustrious Ultimas (Ultimae?), but this has certainly piqued my curiosity. 

The Alto is a veritable Trojan Horse, in the best sense of the phrase. Masquerading as a headphone amp, at which it truly excels, it is also an extremely capable power amplifier. It is able to drive not just small studio monitors but, as I found out, some fairly substantial speakers. The audio quality is ridiculously greater than what one would expect at the retail price. Moreover, I discovered that it comes into its own when placed in a high-end system. It exemplifies trickle-down technology at its finest. Bravo Chord!

Fell Audio Disc

Are there, in fact, degrees of counter-intuitiveness? Bear with me, because I am quite sure this is a valid question.

I’d suggest that, in the current climate, it’s counterintuitive to launch a brand-new hi-fi company. It’s more counterintuitive (counter-intuitiver?) to make one of the first two products your new hi-fi company launches a compact disc player. And it’s even more counterintuitive (counter-intuitivest?) to build this product in the United Kingdom, uncertainty surrounding Donald Trump’s “Will he? Won’t he?” trade tariffs notwithstanding.

And yet here we are. Fell Audio – for this is the company that’s the cause of all these questions – is a new UK hi-fi company. It has the backing of venerated British audio retailer Peter Tyson. There are echoes of the way Cambridge Audio emerged from the Richer Sounds empire back in the day. Fell Audio has been developing the products it’s brought to market (this ‘Disc’ compact disc player and the similarly adventurously named ‘Amp’ integrated amplifier) for three years. During that time, the company has benefited from Peter Tyson’s unrivalled knowledge of both the hi-fi market and its customers. And while not enough audio companies indulge in comparative testing, Fell Audio has spent its time doing little else.

Fell edge

Designing and constructing its products in the UK has, by the company’s own account, given Fell Audio an edge in overall quality, sustainability, and reparability. A five-year warranty and a generous repair window are certainly indicative of confidence.

And anyway, let’s be honest: no one imagined the compact Disc would rise, even a little, from the ashes created by the advent of music streaming. No one anticipated the format that Generation Z would champion, let alone Generation Alpha. No one thought releasing new material on CD would become as important to record companies as releasing it on vinyl. And yet, yet again, here we are. Maybe Fell Audio has read the room correctly.

On the outside, the Disc is quite carefully and almost playfully reminiscent of iconic British hi-fi components from back in the day – I can’t be the only one who’s clocked the Disc and been immediately reminded of the A&R A60 amplifier they have in the loft, even in the silver finish of my review sample (black is also available, naturally). At 75 x 440 x 300mm (HxWxD), it’s a standard width but gratifyingly low-rise, and the standard of build and finish is pretty impressive for the asking price.

Slot-loading

The fascia combines black and green illumination that evokes the look Naim Audio has only recently abandoned. A slot-loading mechanism capable of handling CD, CD-R, and CD-RW discs sits above a row of capacitive touch controls handling the obvious playback controls, and to the right of this is a green-on-green dot-matrix display. The display is above three more capacitive areas, allowing you to repeat one track or the whole lot, randomise playback, and control the information on the display or switch it off altogether. A big power on/off button on the right completes the line-up.

(These functions are duplicated on the supplied remote control handset, although this item is perhaps the only evidence that Fell Audio has built the Disc to arrive at a specific price-point. If there’s a more humdrum and inexpensive-feeling handset available anywhere else in hi-fi-land I’ve yet to hold it.)

Around the back there’s a chunky kettle-lead connection for mains power and a pair of stereo RCA analogue outputs. Fell Audio has also included both digital coaxial and digital optical outputs in case you want to use your Disc purely as a transport. This statement, of course, assumes your system features a DAC more capable than the ESS Sabre ES9018K2M that’s fitted here. 

Chunky

This more-than-adequate DAC chipset is joined under the bonnet by a chunky toroidal transformer. Just as with the ESS DAC, the specification of a power supply of this type is a statement of Fell Audio’s intent – few comparably priced CD players have such capable digital-to-analogue conversion circuitry, and fewer still forgo switched-mode power supplies in favour of something more efficient (and expensive).

I can’t deny feeling a little frisson of both excitement and nostalgia when I dig out a selection of compact discs from the archive to put the Fell Audio Disc through its paces – it’s been a while since I had a CD-only listening session. As well as connecting the Disc to its Amp partner driving a pair of ELAC BS305 stand-mounters, I also use it as a source in the permanent system of Naim Uniti Star and Bowers & Wilkins 705 S3 Signature on FS-700 stands. And while it works gratifyingly well in an appropriate system, it also stands up well in what is, frankly, an utterly inappropriate system.

Fell horses

When playing CDs as varied as Patti Smith’s Horses [Arista], India by Gal Costa [Mr Bongo], Mary Lattimore’s Goodbye, Hotel Arkada [Ghostly] and This Could Be Texas by English Teacher [Island], the Disc proves even-handed and non-judgemental. It’s not the most demonstrative listen you ever experienced, but its willingness to get out of the way of a recording goes a long way towards making up for its slight lack of assertiveness.

It’s really only at the top of the frequency range that the Disc’s mild hesitancy is in any way problematic. Treble reproduction is open and has decent substance, but there’s not an awful lot of bite or crunch to, say, the upper register of Mary Lattimore’s harp. It’s hard to interpret ‘politeness’ as a negative in most walks of life, I’ll admit, but the Disc may be more couth than is absolutely ideal.

After that, though, the news is all good. The midrange is similarly open, but where the treble is understated this area of the frequency range communicates in quite a forthright fashion – the amount of fine detail it can extract makes a voice characterful and direct. At the bottom end, there’s respectable punch and quite a gratifying amount of variation in tone and texture. And the Disc’s even, undemonstrative tonal balance makes recordings sound coherent and unified from the top of the frequency range to the bottom.

Carefully defined

It can create a fairly large, well-defined soundstage; this player, given the right content, sounds quite spacious and organised. Some CD spinners can make the Patti Smith recording sound congested, but that’s certainly not the case here. There’s no hint of the closed-in about the way the Fell Audio operates. This uncongested approach isn’t at the expense of intimacy or immediacy, either. There’s a positivity to the way it describes a stage that combines with the space it creates in the most gratifying way.

There’s a fair amount of well-supervised energy to the Disc’s sound too, a decent facility with dynamics that makes the upticks in volume or intensity in a recording fairly obvious without being in any way startling. Where the broad ‘quiet/loud/VERY LOUD’ variations English Teacher constantly indulge in are concerned, they’re more than alluded to without being made absolutely explicit. ‘Politeness’ again, and once again it’s no bad thing in the context of the product and its likely partnering equipment.

Up the ante

The control of low-frequency information, especially at the moment of attack, makes for a coherent account of rhythms and tempos. If you up the ante a little with a listen to Snap My Finger by Kaytranada featuring PinkPantheress [RCA], there’s authentic momentum to the presentation. If it’s really dancefloor drive and thrust you’re after, you may find the Fell Audio Disc rather too easy-going. For the rest of us, the ability to at least gesture towards the more corporeal aspects of music-making will be sufficient.

Ultimately, Fell Audio has done the right thing with the Disc, no matter how outlandish the idea might seem on paper. Compact disc players as capable as this seldom cost this little. Your choice of sub-£500 machines is enhanced quite considerably. If you didn’t fully understand why you were holding on to your legacy collection of CDs, well, now you know.

finite elemente CARBOFIBRE° Statement

In the already high-end world of finite elemente equipment support systems, CARBOFIBRE° Statement stands above them all. We’ve already looked at the first versions of the CARBOFIBRE° Isolation base in Issue 189. We also covered the Carbon version of the Pagode Edition Mk 2 equipment support system in Issue 204. But the CARBOFIBRE° Statement takes the concept to new standards. 

You use CARBOFIBRE° Statement with heavyweight power amplifiers and large analogue sources. However, it also features a more complex internal structure than the standard CARBOFIBRE° models. This complexity makes finite elemente’s ultimate isolation product suitable for any audio component. The company isn’t selling itself short – the CARBOFIBRE° Statement can hold up to 350kg of audio electronics. Also, the CARBOFIBRE° SD is more than good enough for sub-50kg products. Meanwhile, the CARBOFIBRE° HD has a load capacity of up to 100kg. 

Size matters

The big difference is in the internal layout of the three CARBOFIBRE° models. The 23mm thick SD has a single ultra-light honeycomb core wrapped in carbon fibre. HD effectively doubles this arrangement with two honeycomb cores, each encapsulated in carbon. This results in a 45mm thick platform. The CARBOFIBRE° Statement stands 85mm thick and features multiple honeycomb cores wrapped in carbon fibre. Reinforced inner layers improve torsional rigidity. This torsional strength might seem like overkill – it’s unlikely that your power amplifier will pull a Top Gun-esque high-G roll. However, in a high-mass, high-torque turntable, the greater the platform’s torsional rigidity, the better.

Foot detail

The CARBOFIBRE° Statement includes four finite-element CERABASE° ceramic ball-interface feet as standard. That is a departure from the SD and HD versions. These versions offer CERABASE°, CERAPUC°, or CERABALL° products as optional upgrades. There’s a reason for this: the original CARBOFIBRE° platforms are considered an upgrade to finite elemente’s platforms in its Pagode support systems. The CARBOFIBRE° Statement is a stand-alone device. It could sit inside a Pagode system for turntable users. The degree of custom sizing suggests it is ideal for such settings. However, it is more of an independent platform. 

Double bubble

At the rear of the CARBOFIBRE° Statement’s top plate is an inset pair of precise bubble spirit levels. These are set at 90° to best level the platform on its four CERABASE° feet. Its feet remain locked in place during shipping. An Allen key releases the foot, decoupling the platform from the outside world. It comes shipped with the appropriate tools (Allen key) and the high-end-obligatory white gloves in its solid packaging.

Levelling aid

Setting up is straightforward, if you level before installing your behemoth amp or turntable. Or maybe your DAC: high mass is becoming ubiquitous in high-end audio.

It might be worth double-checking a few days after installation to see if anything has changed with the addition of hundreds of kilos of audio. However, such is the solidity of the CARBOFIBRE° Statement that it’s more likely down to the flooring beneath the platform than to the platform itself.

Hands off

I’m used to the inherently ‘hands off’ approach to sound from finite elemente products. I was pleasantly surprised at how much more (more accurately: how much less) you get from the CARBOFIBRE° Statement. It has a tiny sonic footprint, to the point that you quickly hear where most tables hold back the sound. Bass seems to benefit from the CARBOFIBRE° Statement in the most immediately audible manner. There are increases in texture, definition, precision and ‘slam’. It’s as if your loudspeakers just got a bigger, tighter, and more precise bass response system.

CARBOFIBRE° Statement does not change the tonal balance or emphasis of the system; it just lets those bass notes be better defined, unconstrained, or unaffected by the product they rest on. You then start to hear the resolution boost permeate through the rest of the audio band. There is greater space, dimensionality, dynamic range and shading across the board. Yes, these changes are easiest to hear on well-recorded acoustic music. Paradoxically, the extremes of jazz trio and full orchestra register the improvements fastest. But once experienced, they apply universally.

No fake bloom

The sound produced isn’t a fake bloom in the system; that extra bass doesn’t mean added volume or a boost in the bottom end. The equipment on the CARBOFIBRE° Statement gets as neutral a platform as possible to show what it can do. And, for super-high-mass devices, such platforms are hard to find elsewhere. High mass places excessive strain on most audio platforms.

The CARBOFIBRE° Statement extracts the most out of a select list of extremely high-performance products, where nuance is everything. The company is like a Formula One team, getting an extra 1/1000th of a second of performance from an engine, resulting in a race-winning car. However, with the CARBOFIBRE° Statement, this takes a little time to parse. The additional bass information initially makes the listener think the music has slowed down slightly. A few minutes later, your brain starts processing that extra bass information correctly, so the sound seems to speed up again. I’ve occasionally encountered this in extremely well-balanced, full-range systems. Moreover, it’s almost like our brains hear this as more of a live event and take a few moments to reboot. 

More than heavy

The benefits of the CARBOFIBRE° Statement don’t simply apply to super high-mass devices. You get better bass definition and texture, as well as a greater, more effortless sense of dynamic range. There is space around the instruments and inherent honesty in the equipment’s tonality. This is true no matter the product that sits on the platform. 

Unlike many top-notch equipment support systems that wear their technology on the outside, which results in sometimes ‘challenging’ looks, finite elemente has long been a proponent of a more elegant solution. The CARBOFIBRE° Statement extends those refined lines to support the heaviest audio electronics. But even when used with products that don’t weigh as much as a car engine, the CARBOFIBRE° Statement’s ability to let the device play without sins of omission or commission places it among the best equipment supports. Furthermore, it does so without looking like an oil rig!

World Premiere: The new Ideon Nous

29 May 2026 – Athens, Greece – IDEON Audio proudly announces the all-new Nous, a long-anticipated high-end digital playback platform representing a major new chapter in the company’s evolution of integrated reference-level digital audio systems.

The public will have the opportunity to experience Nous for the very first time during HighEnd Vienna 2026, where IDEON Audio will officially present and demonstrate it.

HighEnd Vienna 2026
Thursday, June 4th – Sunday June 7th

Information: George Ligerakis, Ideon Audio, [email protected]

HighEnd Vienna 2026 Locations:

Level 1, room 1.68    WORLD PREMIERE OF Nous (Ideon Audio Room)

Level -2, room -2.41 EUROPEAN PREMEIERE of Axiom DAC (Ideon Audio with Brodmann Acoustics Room)

The all-new Ideon Nous.

The Nous has been engineered as a complete high-end digital playback platform, integrating a fully balanced DAC, network streamer, and analog preamplifier architecture into a single uncompromising component.

Purpose-Built Digital Signal Architecture

Unlike conventional streamer-based products built around generic computing platforms and adapted consumer-grade audio stages, Nous has been designed from the ground up as a purpose-built audiophile signal-perfection environment where streaming, digital processing, clock management, DAC conversion, analog amplification, and power regulation operate as one coherent architecture.

At the heart of NOUS lies a high-performance reference-grade DAC platform combined with an integrated high-resolution network streaming engine optimized specifically for bit-perfect playback operation and state-of-the-art audio environments.

Its native streaming architecture supports today’s major digital ecosystems including Qobuz Connect, Spotify, AirPlay, UPnP streaming, Audirvana integration, local library playback, NAS rendering, and Roon Bridge operation, while maintaining a highly stable and very low-latency streaming environment designed for maximum sonic integrity.

Real-TimeCore™ Streaming Intelligence

The streaming engine itself operates under Ideon Audio’s proprietary Real-TimeCore™ playback philosophy, where rendering resources are highly prioritized exclusively for audio playback tasks. This dramatically reduces unnecessary computational interference, process instability, timing inconsistencies, and digital artifacts that negatively affect musical realism.

A New Generation Playback Experience

Nous also introduces a completely redesigned playback application ecosystem from Ideon Audio, including the user interface, library management structure, metadata architecture, navigation logic, responsiveness, and overall interaction flow between user and streamer. The objective was not merely functionality, but the creation of a genuinely modern, effortless, and highly responsive high-end streaming experience.

The new platform has been specifically engineered to operate as a plug-and-play environment while dramatically improving operational stability, usability, responsiveness, and long-term user satisfaction.

Fully Balanced Analog Control Platform

The Nous follows a true, fully balanced signal philosophy from input to output.

Its true balanced analog signal path and fully differential analog topology provide superior channel separation, lower distortion, improved common-mode noise rejection, and greater overall signal integrity throughout the analog domain. Combined with a precision, digitally controlled analog potentiometer architecture and a high-current balanced output stage, the Nous delivers exceptional transparency, dynamic authority, tonal realism, and spatial precision.

Unlike many integrated streaming devices where the preamplifier stage exists merely as a convenience feature, the Nous preamplifier section has been engineered as a serious high-end analog control stage fully capable of operating at the center of demanding reference-level systems.

The unit also incorporates two fully balanced analog inputs, allowing seamless integration of external analog sources while maintaining the integrity of the balanced architecture.

Digital connectivity includes USB Audio, optical digital input with galvanic isolation advantages, and coaxial SPDIF input for external digital transports and digital sources.

Advanced Low-Noise Signal Governance

Internally, digital architecture has been engineered around advanced low-jitter principles and proprietary signal optimization techniques designed to preserve timing precision before digital-to-analog conversion takes place.

Dedicated power regulation stages independently manage analog and digital domains to minimize cross-contamination between circuitry sections and dramatically reduce digital noise influence on sensitive analog stages.

Powerful, ultra-low noise linear Power Supply

Attention has been devoted to the grounding strategy, noise-management architecture, and power integrity throughout the entire device. The fully linear, ultra-low-noise, high-energy power supply ensures stable energy delivery under all operating conditions while preserving low-level detail retrieval, transient accuracy, harmonic integrity, and micro-dynamic behavior. Two separate oversized transformers, specially designed for the Nous, independently power the analog and digital circuits, ensuring that each section receives exceptionally stable and ultra-clean power.

This approach allows the NOUS to achieve a highly resolving yet natural presentation, characterized by exceptional clarity, stable imaging, precise spatial organization, tonal density, and an effortless musical flow.

The Unified High-End Audio Hub

By integrating streaming, DAC conversion, analog preamplification, low-noise architecture, and advanced playback technologies into a single chassis, Nous dramatically reduces cable complexity, grounding inconsistencies, interface mismatches, and signal degradation typically associated with complex multi-box digital systems.

Τhe result is a single-chassis high-end audio hub engineered for top-notch audiophile and reference playback systems – combining advanced digital architecture, analog refinement, operational simplicity, and uncompromising musical performance into one unified platform
