OP,
Ive owned all tube systems; Roger Modjeski amp RM 200, OTL Joule Electra, Rogue M150s with cryoed 6550s and EL 34s... several tube preamps; Lazarus, Modulus, Lector balanced tube preamp, multiple SS amps; class A (Kinergetics KBA 75), AB; Bryston 3B, Conrad Johnson, Classe, Brown Electronic Labs BEL 1001 MkII, Parasound A23, more that I can’t recall...
I have also owned quite a few Class D; PS Audio- GCC 250, which I still use in my tv system &, M700s (very nice), several W4S, Emerald Physics, and most recent an EVS 1200, dual mono based on IcePower AS1200 modules, a creation of Ric Schultz with lots of pixie dust: it blows away many/most, and compares to the best amp in memory, the KBA 75
I am on the 1.4 year list for a LSA Voyager GaN based
