I've owned several Class D amps (and before that Class A/AB amps and the last one I owned was discontinued in the last year or so and I believe the last couple I owned were in the $10k retail list price range when they were new).  I drive Thiel 3.7s which are not the easiest load in the world. I started with a IcePower 1200AS stereo amplifier which I broke in using a secondary system as I was not sure about how it would perform in the main system.  I was in shock after listening in the secondary system how much better it was even right out of the box vs. a well know brand Class A/AB amp and in bigger shock when it drove my 3.7s easier and was better sounding in my main system.  I then went to a modded dual mono 1200AS which was even better. I owned another Class D as well and I did bring the first Class D I owned over to someone elses home and I thought it sounded better vs. what they were using (as did another person in the room as there was 3 of us in total).

I currently have in the secondary system noted above the Premium Audio Class D amplifier (driving a pair of Selah SA2s).  In the main system, I currently use a VTV Purifi amplifier (1ET-7040SA) with a vacuum tube input buffer.  In the context of these systerms, what I currently use sounds better than what I used in the past. So like anything else, I'd encourage anyone to listen for themselves and decide what they like or don't like. Obviously, everyone may not have identical tastes and not identical rooms or associated components.

I would stay away from the GaN amps as nearly all but Orchard have load dependent frequency response. The current state of the art is Purifi with Hypex a close second. Both have inaudible distortion, load invariant frequency response, run cool and will drive just about any load. Prices are very reasonable- I paid around $2400 for a set of 9040 Purifi monoblocks with 900W into 2 ohms, auto on/off feature, selectable gain, etc. No brainer.

Phil, what were the other A/B amps that you used before? What did you like better about the class D?
I am curious about the new Bryston class D. Have you ever heard them?

Not a good showing.
