I have owned quite a few class Ds over the last 2 decades. By far the best by far is my EVS 1200 a dual mono Icepower AS 1200 design with lots of Ric Schultz tweaks. Upgrading cables makes a HUGE difference
I also have a LSA Voyager GaN 350 which I much preferred over the EVS, but since then I have significantly upgraded all wiring, plus, replaced a Marantz HD CD-1 player used as a transport with a Audiolab CDT 6000 (fabulous bargain). Alas, I managed to take out one module in the Voyager, and have not been able to compare again
