VALVET A4e mono blocks

The A4e are a further development of the A4-CB mono-blocks using a separated power supply unit with even more Class-A power!  Long lasting pleasure The VALVET A4e mono blocks are currently the most potent power amplifiers in our line-up. 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 A4e 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. Performance and dynamic. The A4e 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. Compared to the A4 power amps they deliver even more fine details and play even more effortless and natural. The A4e mono blocks have an output of 65 watts per channel into 8 ohms and 105 Watts into 4 Ohms. We believe that you will not feel the need for more power for a long time. The A4e 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 A4e mono blocks operate in Push-Pull 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 massive 500 VA toroidal transformer in a separate case, 8 ultrafast 15 A rectifier diodes plus 176.000 µF of filter capacitors per channel guarantee excellent performance and stability. No capacitor in the pure silver wired signal path. Power amp and power supply are equipped with excellent feet from bfly Audio. "JUST PURE MUSIC!"

Reviews Fidelity Award Winner 2020 in the catagory Premium/Amplifiers/Mono-blocks: "...the new "e" generation rests on stable, sonically excellent feet from Alto-Extremo. The 65 watts at 8 ohms make music amazingly dynamic and stable...those who do not get goose bumps at what the Valvet mono amps offer in terms of drive, transparency and clarity at this point should urgently make an appointment to see a doctor..." Greg Voth of The StereoTimes concluded (06/2019): "...even with a solid state preamp in the mix, the music felt very relaxed, rich and sounded, in a word, lush. Each note was delivered with panache over the brute force of other power amplifiers and in a way that subtly coaxes and charms the listener to continue their musical journey rather than submit to over-arched and brutally dynamic intensity. These Valvet a4e’s are the real deal… get where I’m coming from?" CLICK HERE to check out the entire review Jochen Reinecke, Fidelity Magazin (02/2018): "...the good news: the Valvet mono-amps are actually better! Better to such an extent that the price difference is entirely justified. This can be seen in three different areas: First, micro-resolution in the upper treble has markedly improved...  Second, there is a marked improvement in spatial positioning. Pin-point spatial orientation of instruments in the ‘background corners’ has increased, but also micro-orientation within the plane...Finally, the Valvet mono-power amps have become even faster: their ability to mobilize enormous energy from a moment of absolute stillness - without limits, compression or distortion... Those who do not get goose bumps at what the Valvet mono amps offer in terms of drive, transparency and clarity at this point should urgently make an appointment to see a doctor. My conclusion: Valvet have managed to significantly improve an already great product. Congratulations!" CLICK HERE to read the entire review in English, or HERE for German Review of the predecessors models A3.5 & A4: Patrick Dillon of HiFi Zine (May 2017) 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..."  CLICK HERE to read the entire review Key Kim reviewed the A3.5 and soulshine for The Stereo Times December 2009 "...the new Valvet Block A3.5s are incredible sounding amps. It was hard to believe these were only 50 watts per channel. They drove my reference Conspiracy loudspeakers with great authority and power. The Valvets possess purity and remarkable transparency that allows them to provide an amazing musical experience. At $5.590.00, it’s a bargain! ...this preamp (soulshine) had a natural purity and open airy sound which brought me closer to music. Stay tuned for a full review"  Review of A3.5/soulshine in the German magazine "Image HiFi" 02/2010 by Roland Kraft: "...once they’ve warmed up to operating temperature, these seemingly insignificant audiophile amps fascinate the listener with stupendous transparence. In addition, a spacious sound stage with an impressive breadth immediately captivates the listener... the Valvet amps are agile, never strained, and always light-footed. They constantly create a fresh, clear - but never cold - breath of air, and at the same time easily concentrates on the essence that can hardly be described. The tubes and transistors complement each other perfectly, making an lasting impression that can hardly be equaled in this price class..."  - read the entire  review (in German) Review of A3.5/soulshine on "Positive Feedback Online" Issue 48 03/2010 by Robert Learner: "...smooth, dynamic, lively, and organic. Tonal purity suggests straight-wire gain with a dash of inner glow. Soundstaging is precise in localization... 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."  - read the entire  review The review "Giant Killers" for A3.5/soulshine on "The StereoTimes" 06/2010 by Key Kim: "...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..."  - read the entire  review Review of P2c/A3.5 in the UK magazine "HiFi+ Nr.76" 10/2010 by Jason Kennedy:  "...the P2c is a well built preamplifier that offers an awful lot of sound quality for the money, you will be hard pressed to equal it sonically with a better looking product. The A3.5 is by contrast very nicely cased and extremely engaging with enough grip to keep you rocking in the context of a relaxed and revealing demeanour. And I thought I didn’t like the sound of silver!"  - read the entire  review Review of L2, E1r and A3.5 MkII on the German web-zine "HIFI Statement" 07/2013 Amre Ibrahim: "...we cannot thank Mr. Cornils enough for enriching the world with high-end components such as the Valvet E1R, A3.5 MKII and L2. At a time when many amplifiers are beyond the financial reach of the average consumer’s purse, he provides an impressive counterpoint with unusual approaches to development and robust Made-in-Germany fabrication: absolutely consistent, highly musical audio components at an affordable price. More, please, Mr. Cornils!"   - read the entire review   - here for original German Customer Feedback Feedback for the predecessors models A3.5 & A4 "...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..."
