I wish Audiogon and other audio forums would have a subcategory of amplifiers dedicated to class D. There may well be reasons they do not break it down to that level, but trying to find information specific to D-amps requires a lot of winnowing down amplifiers not in the category.
One of the problems you're up against is that the sound of class D amps varies as much as the difference between tube and solid state. Depending on what people have heard, you see really variable comments- some people will never try one again, having heard something dreadful (and rightfully so) and others have had the luck to have heard (likely one of the more recent) class D amps that really tick all the boxes.
20 years ago class D was a joke. It isn't that way any more. I'm of the opinion that any amp manufacturer that doesn't make a class D amp will get left behind in short order.
