I tried a D-Sonic amp with a Modwright 36.5 preamp. It was a nice amp, crystal clear, excellent for home theater or background music, but sort of lifeless with 2 ch audio. If you're not familiar with it, the Modwright is a fine preamp (imo), but not particularly "tubey".
Admittedly, I have been a tube guy for a long time. Maybe it was asking too much - I mean, I gave up on solid state amps because to me, there is no doubt that tube amplification sound more like real music - but it sure would be nice if cl. D were "good enough". It soured me on class D, for now, but I haven't tried any of the newer GAN versions.
