Unexpected
I'm having a hard time finding the words to describe how good these amps sound. They just do everything right. Period. ( powering martin logan electrostatic speakers)

gamechanger
As being a sound engineer and an audio enthusiast I was a bit scared when I placed the order and switching from DENON POA 6600A monoblocs to D-amps. I read a lot about them and made my research. Spent hours and hours reading and analysing data. Finally decided to go for the audiophonics MPA-M400ET set. Had to wait for a month, but what the heck. The audiophonics team gave me al the updates in this time and finally received my amps. Installed them and after an evening listening, I was so enthusiastic. It was like a totally new experience. My counterpoint tube preamp and my speakers, a DIY focal Utopia., who are hard to handle at 1,2 Ohm. They sounded so different, so clean, so spatial, it was like they were not there anymore. They disappeared in front of me. I listen to all kinds of music. I know quiet a few songs that are hard to handle for any combination of speaker/amps. And on a pretty fair volume the amps made it smooth listening. This is the amp for me that will always stay in my collection.
Thanks for the good service, the proper build and the switch to D-amps

Summer replacement for Accuphase Power Amplifier
These amplifiers (pair of monoblocs) have been acquired as a summer replacement for my Accuphase amplifiers which are warming my music room to extreme temperatures. Please be mindful that the review is written within first 24 hours of obtaining them and here you will find my initial thoughts which are nothing but subjective. The main concern for me will these amps have enough power to drive my B&W 802D3 speakers. The answer is YES, very much so. Both the deep bass and clear sweet midrange are exactly where they were and where I like them, Off course the treble is as expected, which is very precise. It is not too bright, it is nice. I dare say I am able to hear the decay of the cymbals or notes from piano with better detail than before. I am planning to test these amps for the next week or so and perform a detailed comparison to the Accuphase AMPs. So far so good. I am still worried that the Max power output is 227W which, as tested by ASR, give out continuous (RMS?) power of 131W. So far so good. Class D amps had a bad reputation in the past. I think that the Purify and Hypex crowd are changing the game and giving us music lovers (NOT Audiophiles - although the meaning is same) a whole new perspective on how music can be reproduces with high quality at an affordable price.

Bon rapport qualité prix, il alimente une voie centrale Paradigm founder c90 avec brio, les voix sont claires et charpentés, tous les détails sont là. Évidemment il y a mieux mais bien plus cher. Je recommande.

Incredible price performance
Anyone interested in this amp has probably dealt with measurement data and ASR. Thus, you know that probably one of the best power amps in the world is offered here.
They are impeccably finished and thoughtfully assembled. The sound is mercilessly transparent and clean. I can not imagine that there will be anything better again. Especially not for this price. This is final stage endgame.

A few criticisms: the front LED can be deactivated, but I would have preferred the color red or orange here, so that it is not so annoying at night. A small instruction or parts list, at least on a small piece of paper, would have been nice. But these are both really only small things.

good value, good customer support
This is a good value. For those of you who are accustomed to more old-school amplifiers, you will be surprised how such a light and small package can pack such a big punch. The internals of this unit will definitely make your speakers sing. The external case is good enough. Solid connectors. Simple design.

I ordered this to the USA based on what I've read about this implementation in online forums, particularly AudioScienceReview. The delivery arrived within days, in very protective packaging.

I needed to talk to customer support a few times, and they have been willing to address all my concerns in an ethical manner.

In conclusion, if you're in the market for a Purifi amplifier, I would recommend trying out the Audiophonics implementation.
