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.

In that last article you linked, to the mk II iteration, there was a reference to a fairly extensive run-in period.  How many hours do you have on yours now?
I have 83 hrs. I believe that i read it takes about 165 hrs. to fully break in. What i have noticed from day one to now is that the soundstage is real in dimension, performers are real in size. Sometimes with even the best and most expensive equipment while the performance can be fine the mental image is that the performers are 3-4 feet tall. Without being forward the Audion is projecting a real life image. I have heard this very few times, that the Audion is capable of doing this at it's price point to me is impressive.
In my decade search for a great class D amp i have heard two other amps with with GaN outputs and while they sounded good they were not great. I just came across this video with Alberto of AGD that explains that the GaNs in his amps were designed for audio, this explains for me a big part of the reason that his amps sound not good but great.

Re: AUDION amps • here is what was conveyed to Alberto after some listening to his monoblocks in my system...

“Everything is performing as it should...

The clarity is phenomenal. One aspect which I greatly appreciate is the ability to effortlessly hear the enunciation of words sung on tracks with other competing instruments present.

And the noise floor/distortion is so low that when listening to orchestral tracks, the Audions make interpretation of subtle fluctuations of instrument dynamics/articulation very clearly perceived.

Another one for me is how the dynamic attack of the instruments especially drums/percussion is just more “REAL”...

As a lifelong musician I’m very familiar with how true acoustic instruments hit the listener/performer. These amps have gotten me closer to that realism than any other to date.

I could go on further but these are a few of the qualities that I haven’t heard to this degree with any other amps in my system.”
