@kuribo , if you were going to buy now a class D amp, which one(s) would you choose? Or, do you think that much better class D designs may appear in near future, and hence would you rather wait until then?
Current products by Purifi and Orchard are beyond the limits of human hearing as far as distortion is concerned. The limiting device in the playback chain is not the amp, it's the speakers and the room. I would advise looking into Purifi and Orchard with state of the art tech and performance and then turn my attention to other links in the play back chain.
