Knut Cornil’s new A4 Mk.II Class A mono-blocks.
The Mk.II version of these small footprint Class-A mono-blocks has been much improved. 33% stronger transformers (now 2 times 400 watts), new audiophile resistors and silver wiring with real cotton isolation elevate these close to the performance of Valvet’s top-line mono-blocks, the A4e... and all this while still maintaining Valvet’s small footprints.
Factory lead time is currently 4 weeks.
Marc of The Audiophile Weekend Warrior writes (February 2020):
"...there’s a purity and density of tone, a freedom from electronic haze and grain, a fluidity of expression that’s subtle in absolute terms but significant in visceral ones. The Valvet A4 Mk.II is delightfully expressive, sweet and pure, with an honest and unforced way of capturing the warmth and beauty of a performance..."

Review of the original A4 by HiFi Zine. Patrick Dillon concluded:
"...and this is how I end up feeling about the Valvets. They are so finely balanced and cohesive that you might at first wonder about their unique qualities. They won’t immediately catch your ears with detail, but those details are there to be heard; they won’t blow you away with unparalleled bass depth, yet the bass is full and realistic; they can deliver space and decay while slamming you with dynamics when required. When you hear them over an extended period of time on music you love, you come to realize there is something quite special about these amplifiers. In their understated manner, small footprint and relatively low power specification, the Valvet A4s are capable of delivering musical reproduction that is as good as I can remember hearing. There was never a recording I played where I felt I was missing something or that the amps were not delivering the goods, and that’s across multiple genres and ages of music. Class A all the way..."

Again, long term satisfaction, real value and reliability are key values. Those who own these power amplifiers can put any worries about amplification to one side for a very long time! What the A4 conveys in terms of musical information is simply breathtaking! We encourage you to compare them to the top brands and then decide which delivery gives you the greater pleasure.
The A4 amplifiers are extremely quick, controlled and powerful. They don’t force themselves onto the music, but rather support its flow and the listener’s involvement. The A4 mono-blocks deliver an output of more than 90 watts per channel into 4 ohms (55 watts into 8 ohms). This is a very conservative measurement, as with all VALVET amplifiers. We believe that you will not feel the need for more power for a long time.
The A4 power amplifiers, in common with all other VALVET amplifiers, have an extremely stable power supply which gives them an excellent ability to deliver current, thus keeping even the most difficult speakers on the market on a tight leash. The A4 mono-blocks operate in Push-Pull pure Class A mode with just a single pair of transistors in the output stage. We believe that the common practice to employ several transistors in parallel required to produce a higher output is detrimental to the sound quality.
A 400 VA toroidal transformer, 8 ultrafast 15A rectifier diodes plus more than 130.000 µF of filter capacitors (Mundorf’s Finest) per channel guarantee excellent performance. No capacitor in the pure silver wired signal path. "JUST PURE MUSIC!"
The predecessor, the Valvet A3.5 monos (and the Valvet soulshine pre-amp) was StereoTimes’ Most Wanted Component Award winner 2009.

Transients have snap and life, and decays are full-blooded, something I’ve come to associate with Class A electronics versus some other designs. There is none of the sterility I’ve heard with some other solid-state amps... haven’t heard better for the money and certainly worse for more. These components have some magic, something past competence or even excellence and into the illusion of ’real’. You can find components that do this or that better in the price range, but none I’ve spent time with are as addictive. They get the essence of the music... The sound quality is not only that good, it’s that true—park them on your rack for the next ten years and find other things to worry about."
Key Kim of StereoTimes wrote: "...from the very first notes on the very first album, it was obvious that the Valvet combo was something special. In our age of hyper-priced imported components, it’s not just good sounding (even at just over $11k) The Valvet components are the real deal regardless of price.... They are giant-killers in that they provide the ultimate musical bliss without breaking one’s bank account. If you’re looking for that really great sounding system that isn’t stratospherically priced, then look no further than Valvet..."

Here only a few testimonials from US customers:
"...after over a week of listening and comparing, I can honestly state that Valvet equipment has the performance to beat. I don’t know if I had mentioned to you that I own a Pass Labs XA30.5 stereo amplifier, but that is what I compare amplifiers against, and I can confidently state that Valvet has the better amplifier...I compared back and forth between the Pass Labs unit and the Valvet A3.5 mono-blocks using the same sources, same preamp (my Valvet), even the same cabling, and time after time I selected the Valvets as having the better sound, staging, bass attack, and highs...Couldn’t be happier!"
"...this evening I sat down to read the July/August 2011 edition of The Absolute Sound Magazine, and thought I’d put on some pleasant but mostly background music as I read. ’The most relaxing Jazz Piano music in the Universe’ by Denon. Just background stuff for when we have people over for dinner, etc. OK, disc two "Lover Man" with Sonny Stitt and Cedar Willams. The overall presence and (fill in every over the top audio review you have ever read) and the Vibraphone bloom and decay, etc. etc. made me put my beloved Absolute Sound down to e-mail you with my wholehearted appreciation for your having this, in my experience, the best audio value for power amps (with appropriate front end, cables and speakers) in the universe--tubes or solid state..."
"...the A3.5’s continue to impress me with their ability to really convey the music and the performance on a wide range of music, vocals, and instruments. Truly amazing! I am very satisfied with this purchase and everything stated about them is absolutely spot on without any hype..."
"...timbre, nuances, speed (bloom and decay), soundstage depth and width, dynamics and imaging were all spot on without being forced, etched or "driven" in the HiFi sense. I was somewhat skeptical that the relatively low rated wattage (A3.5 mono bocks) output would really do the job, but once installed, the volume setting on my preamp was very close if not slightly less that previously using tube amps rated at least twice as high and solid state amps rated four times as high in output wattage... Vocals (male and female) were rendered with more subtle shadings and were startling in the "you are there sense", bass is now much more "fleshed out" in all its potential in timbre and dynamics, snare drums, brushes, cymbals and top hats are extremely more involving and piano is rendered in a manner that I thought I could never reproduce in comparison to the real thing.... In short, I have moved from listening to music to experiencing the performance. An amazing feat of engineering from an individual who has not only the skills and intellect but the passion for music and this wonderful hobby/obsession called audio. Thanks again for making this wonderful amplifier available in the United States."
"...I was very impressed (awesome). Compared to some way more expensive gear, the Valvets (soulshine & A3.5) held their own in an excellent way. And for what they cost, I have to scratch my head and wonder..."
