Competitive class D amp suggestions

I have been Class D fun since a few years ago when i bought my first class D amp. I like the concept, in general, and all the attractive features of this class of amplifiers. I tried 4 different ones, currently i  stayed with one of them that i consider to be the best among all four amps. I do enjoy and like it. At the same time,  my 5 watts SET amplifier (with more than 100 times higher distortion according to the specs) gives more natural and (surprisingly) notably cleaner sound (THD of the class D amp is 0.001). The soundstage  of the class D amp is not so bad but that of the tube one is still better.   

I remain attracted by class D amps though. 

Any fresh suggestions on reasonably priced class D amps (i mean excluding  non-reasonably priced class D amps, e.g., Merrill amplifiers)?

Any comments on non-reasonably priced class D amps are also welcome (so far i was not able to audition many class D amps and am curious if there are some which could really compete with Class A).

That would be very interesting, please keep us posted! 

I will not sell my Megaschino, also because no Cherry amp will ever be again produced (on this land, at least; perhaps Tommy is doing that in heaven) and it will be a benchmark for me. But I do wish to arrange the problem in its right channel! (so far,  i have no idea  who could help me with that)

Who here actually heard in their own system the Atmasphere class d amps? I'm in line to hear a pr when my dealer gets his demo set. 

I have a pair incoming.   I currently use a Pass XA30.8 so it will be a very interesting comparison!    I love the Pass but my listening room doesn't have AC so if I can find something I like as well but runs cool, that would be great :)

That could be a conceptual change from Pass labs XA amp. If you like how Pass Labs  amps sound, you may also like Nuprime class D ST10 monoblocks, but they do get a bit hot in long run.

Let us know your first impressions on Atmasphere monoblocks vs XA 30.8.

Speaking of 2nd and 3rd order harmonics and their influence on what we hear...this is an interesting post/analysis.....

@snapsc Thankyou for that link, that is tremendous information.

This leads me to wonder about the virtues of Purifi module Class D amps. Tests reveal the near total absence of any audible 2nd and 3rd harmonics.

I guess it depends on the maker using Purifi technology, but I have recently been reading all I can about March Audio.

So "good" is bad. True.. While I haven’t auditioned, I remain cautious.

I am very sad that Ralph’s Class D is designed only for Nth America and Canada (and perhaps a few others) electricity supply, otherwise I’d be placing my order.

AGD? Hmm. If I really have to, kinda thing.
