AGD Audion GaN Class D In The House

During the last decade i have managed to try in my home 95% of the Class D amps offered to the public these include the so called break thru offerings of the last year or two. While there has been progress the class D signature remained and this included what was lacking in class D amplification.

When i heard about AGD i thought here we go again because i had been there and done that so many times with class D but the GaN tech had me intrigued so i bought a pair of the Audion amps, i thought i would give class D one more go.

I received the amps two days ago and have about twelve hours of listening. From the first minute onwards these amps had my full attention. There is no connection between this class D amp and class D i have heard in the pass no connection what so ever. Forget classes A, A/B, D or whatever this is just an excellent sounding amp, it delivers music that belongs at the upper levels of Hi End audio reproduction.

It`s only been a couple of days of listening but i`m so taken back at the quality of sound i just had to share. I will add more the more i listen, good or bad.

@bigkidz Yes, it would be better to say "I've heard many class D amps".  I liked class D from the beginning and in 2008 posted a list of class D makers (today likely much longer).  There are over 50 companies on this list and most of them make more than one model:

I've had the Audions for two years now. They drive my Acoustats 2+2 with ease. Very quick transients. Very clean sounding. Love them. Just had the "tubes" upgraded. I recommend them.
