Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
What's your approach to customer support?
Musical Fidelity (like other Audio Tuning brands) is structured in a pretty traditional way, whereby support and advice are best administered on a local level. Of course, they have a technical team positioned at HQ to help all their partners around the world, and in some more extreme cases you may need to be put straight through to this team. But it's the job of the distributor to support the territory in the best way it can.
What are your favorite tracks for showcasing the strength of your products?
I can tell you this, as we've done this recently for others. These are personal choices:
Simon Quarry – the chief designer – selected these three.
- Low Desert Punk – Brant Bjork
- Moon Love – Electric Moon
- Psychic Chasm – Ozric Tentacles
Heinz Lichtenegger – the brand owner – selected these two:
- Tosca – Puccini, Leontyne Price, Di Stefano, Taddei / Vienna Philharmonic with Herbert von Karajan (Decca, 1963)
- Don Juan – Richard Strauss, Tod und Verklaerung, Also Sprach Zarathustra / Vienna Philharmonic with Herbert von Karajan (Decca, 1960)
What other products pair best with yours?
This is a tough one! Partly because of the diverse range of products on offer from Musical Fidelity. For example, with the A1, we have a lot of success pairing this amp with Klipsch Heresy or Forte IV – but in smaller rooms, our own-brand LS3/5A are a wonderful choice. For Nu-Vista, we pair very nicely with Piega – which requires some deeper power reserves to really get going. So I would say it's very difficult to pair the sonic ID with one brand in particular. Musical Fidelity pairs pretty nicely with a wide range of products, giving customers a great degree of choice.

Our summary
Product Strengths
- Ample power with minimal distortion
- Audionet's ULA (Ultra-Linear-Amplifier) technology, originally developed for medical engineering
- Impressive dynamic prowess and the ability to plumb the hidden depths of CDs and LPs
- Subtle musical and instrumental details come through cleanly and coherently, without compromising life-likeness of tone colors and harmonic expression
- Exceptional bass reproduction, with a rich, detailed, and uniform low end
Product Considerations
- Positive and negative speaker terminals are close together, requiring caution when connecting speaker cables
- Balanced input use involves an op-amp, which some believe impacts sound quality, single-ended inputs are preferred by some
- A preamp should be used to get the best sound from these amplifiers
- Display text changes locations randomly, which some may find distracting
Comparisons (according to reviewers)
- The Burmester sounded cleaner, airier, and more revealing, but could not quite compete with the AMP II MAX in authority over the bass frequencies and in blackness of the background
- The Pass Labs was tonally rich and pleasurably soft, plus the amp gave an extraordinarily punchy presentation, in that it bettered the performance of the AMP II MAXes, on the other hand, it was rather general in the organization of the soundstage and the background wasn't quite as black as with the AMP II MAXes
- Plinius shone in resolution, as well as delivered exceptionally dimensional soundstage and very neutral overall sound, especially in Class A mode, however, it did not have the same punch as the AMP II MAXes, and the sound wasn't equally gentle
- The McIntosh MC-501 delivered a richer and warmer sound, but with less power and extension than the AMP II MAX
Takeaway: The Audionet Max monoblocks offer a powerful and refined listening experience, making music sound engaging and detailed. Their ability to control speakers and reveal nuances in recordings makes them a great choice for serious audiophiles.

Our take on the brand
.png){kind=logo}
Designing an amplifier that would outperform the Zions in bandwidth, output and transparency was a tall order. This amp would need to express all of ampsandsound's most closely held philosophies at an even higher level. More power or complex circuitry for the sake of increasing the cost was out of the question. Where does one go, once they've scaled Everest?
After extensive listening and research, the Citation II was settled on as the basis for the design. This amplifier was designed to be an amplifier in the tradition of Harry Pearson's Absolute Sound - something which had absolute fidelity resulting from the widest and flattest frequency response and as close to an absence of distortion as possible. This amplifier is the proverbial bigger gun for those customers who require even more power than a Zion.
The original Citation II, much like the Citation V, is underwhelming in the power supply. A significantly more robust version was in order, which can supply eight amps per channel, and allows for tubes capable of greater output than the original. This of course necessitated the design of the highest power input power transformer ampsandsound has ever designed. In the process of redesigning the power supply, careful attention was given to improving dynamics, RMS output, regulation and lower distortion.
Depending on the tube selection, the Arch will output between 60-100W in pure class A, and represents our absolute statement on power output. As with the Zion, everything on the Arch is capable of handling several times the rated output power of the circuit. The result is astonishingly low distortion, and a true-to-source amplifier with massive grip on loudspeakers.
The output transformer on the Arch has a practically unheard of bandwidth of 2hz to 110khz at -3dB. Even the excellent original Freed iron does not achieve these kind of figures under real world test conditions. Total output power is 65 watts with KT88s and 85watts with KT150s. The total power is the measure of this amplifier's magic - not because of the output, but because it achieves astounding frequency linearity and vanishingly low distortion while doing so.
A tube amplifier that can reliably reproduce frequencies lower than 20hz is unheard of and one that can descend into the low single digits is mythical. Perhaps most important is distortion figures that would be considered remarkable for a well designed solid state amp, accomplished in a tube amplifier without a single regulator.
The chassis is 10-gauge cold-rolled steel, which imparts even greater damping than the Zions and makes for an imposing amplifier. The choice of 10-gauge steel was born of our founders ability to make singular decisions on the basis of performance without consideration to costs. Each choice in the Arch came about in the same manner, and reflects a pursuit of absolute performance not a proxy vote for profits.
Each monoblock weighs in at around 100lbs, and represents the pinnacle of our philosophy: hand built on turret boards using ultra pure point-to-point wiring, with no expense spared in creation process or parts selection. Wiring assembly alone takes 18 hours per channel, and is done by hand, before inspection, break in, testing and validation.
This amplifier goes far beyond being a modification or clone of the Citation II. Instead, the Citation II serves as a touchpoint for an amplifier built to completely eliminate questions of output and distortion. The Arch is the pinnacle of the low distortion, high power spirit of the Citation amplifiers, and each unit is personally measured, tested and listened to by Justin Weber before shipping.
The sound of the Arch must be heard to be understood. Suffice to say, the Arch simply sounds like music, and demands partnering equipment of highest calibre. Please contact us if you wish to arrange a demo.
Product Strengths
- Incredibly nimble, with every detail highlighted, providing an extra layer of resolution
- Delivers all of the detail and clarity without the traditional fatigue
- The balanced input transformer properly sums the positive and negative legs of the balanced signal, and in so doing retains much of the benefits that you normally achieve with fully balanced amps—noise rejection
- The distortion numbers are exceptional for a tube amplifier
- Compatibility with nearly every commercially available speaker, due to the support of three impedances (4 ohms, 8 ohms, and 16 ohms), and output power exceeding 60 watts with KT88s, and 80 watts with KT150s
Product Considerations
- There are no modern reproductions of the 12BY7A, requiring matched pairs to run the amplifiers
- The bias is fixed—it's selectable between settings, but dialing in the distortion could not be simplified further
- Heavy at nearly 100 lbs each, as there's a lot of iron in both the transformers and the chassis work
- A hint of tube noise was present in one channel when no music was playing, likely specific to the tubes used
- Not a wise choice to any planer but complex crossovers and difficult loads have not compressed the amp in testing
Comparisons (according to reviewers)
- Vs ampsandsound Zion Monos: The Arch Monos are more neutral, faster, and provide an extra layer of resolution, compared to the richer and more harmonic sound of the Zions
- Vs TAD: The Arch is clean, powerful, and has many characteristics of very good solid-state amp, though the TAD approach was similarly neutral in many ways, albeit with a lightning quickness that the Arch did not have
Takeaway: The ampsandsound Arch Monoblock amplifiers are a technically proficient and beautifully built amplifier that delivers exceptional detail and clarity without fatigue. If one wants a vintage but modern sound, the Arch Monoblocks could be a good choice.

Product Strengths
- Completely balanced and DC-coupled
- Uses the Class A 'X-Amp' input stage technology from the 159
- Has a high damping factor over the entire frequency range and a very wide, distortion-free Class-A range
- The thermal concept uses 'universal heat pipes' to keep temperatures constant and low, increasing the lifespan of the amplifier
- Signal processing reaches the input signal unaltered via silver cables
Product Considerations
- The Burmester visual aesthetic will not please everyone
- Power needs are consistently overestimated, and this amp has 100Wpc continuous into 8 ohms
- The single-ended RCA inputs are not available on the back panel, unbalanced input requires an adapter
Comparisons (according to reviewers)
- Vs Burmester 911 Mk 3: The 216 adds extra depth, precision, control, and ability to 'wig out' bass, also more reactive and dynamically dynamic
- Vs Burmester 911 Mk 3: The 216 is the more liquid sounding of the two, is more dynamic, has better bass definition and control, a more even sounding treble, a more open midrange, a keener sense of rhythm
Takeaway: The Burmester 216 is a musical chameleon that is carefully and meticulously crafted, it will bring the best out of any genre. Its utter lack of electronic character is a huge plus, making it a worthwhile consideration for any audiophile.
