at the end of my long quest, I have finally found a couple amplifier/preamplifier that is, in my humble opinion, clearly above the others.

SUMMARY REVIEW: Up to now, I have not been able to find a single weakness. They just sound like the live event! I am not sure we are speaking anymore about electronic device. At this level of perfection, we are dealing with works of art.

EXTENDED REVIEW: This review is about both the AMP-III and the PREAMP-I-MKIII (the previous model before the replacement ULTRA AMP III release)

I have been an audiophile for many years. I have owned quite a lot of amplifiers and preamplifiers (including Plinius SA-Reference, Audio Research Reference series, Nagra, YBA Passion, etc.) and heard most of the so-called high-end amplifiers on the market. 

A few months ago I decided to rebuild a system from scratch. My system was already very good but at each iteration there as a iittle something that was not perfect. So, I have spent a huge amount of time listening for many, many, systems without any consideration of price (of course, money matters for me but I wanted to try to find the ideal system).

As you have probably guessed from the previous sentences, English is not my mother language, so I have to be brief: at the end of my long quest, I have finally found a couple amplifier/preamplifier that was, in my humble opinion, clearly above the others. 

Namely: the AMP-III and PREAMP-I-mkIII. I believe it is the best just because it does everything so right:

- the power is nearly unlimited. (the power transformer reads an incredible 3200 VA).
- the sound is incredibly refined & Powerful
- it works as well with classical music than with jazz or rock
- you easily forget about it and just hear the music
- the building quality is just fantastic and I like very much the design

It should be noticed that most of what I say here about the AMP-III (that I now own) is true for the AMP-II (which is basically the same with less power @ 250/ch but still enough for most situations).

Of course, they are expensive. But much less than many other amps I have tried at home (including LAMM, Goldmund & Krell). 

It was therefore very good news for me to find them so clearly above the others! It could very well be that this is just my taste but this conclusion was shared by my wife and my children so something rather objective could be true here!

Up to now, I have not been able to find a single weakness. They just sound like the live event! I am not sure we are speaking anymore about electronic device. At this level of perfection, we are dealing with works of art.

Nothing is perfect in this world. But both as a researcher in astrophysics (who works on a space experiment and understand something to technical engineering) and as a music lover I would like to recommend with the greatest enthusiasm Accustic Arts amps and preamps.
