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). 


@axo0oxa thanks for this complement. You may still have more successful jumps, you never know. I made similar jumps also replacing amplifiers, and am not sure if more jumps are required. Compared to your tube SET amplifier, what exited you the most in your Vivace amp (except its cool look, i understand that these "tubes" looking as candles at night, may give an intimate peace-like feeling)?

Ralph, thank you very much for this, very, very, sad information. I didn't know him personally but we communicated a lot by email. One can say how a person is based on a letter exchange. He was always positive making good things and was doing that practically alone. He was, really, a very nice guy. Just to tell you that i am writing this message with tears in my eyes, a person whom I never knew personally. He had two daughters  i think. I will miss him...
