I should have led with Ive owned quite few tube products, including an all tube system; Rogue M150s with both cryoed EL34s/6550s, Lector preamp with dif balanced outs, and Raysonic 168 dif balanced CD player (and a 228 that died right when the company disappeared), Accoustat 2+2s with upgraded servo amps, when Judd Barber (Joule Electra) was alive he sent me a small OTL stereo prototype to evaluate, NYAL 150 and 300, and several tube preamps whose names I have long ago forgotten
Having owned many class D amps; PS Audio GCC 250 (still in my TV rig), several W4S (stereo, mono, MC, Emerald Physics 100.2SEs, Audio Alchemy DPA 1, PS Audio M 700s, EVS 1200 which I raved about for over a year, until January of 2021 when my LSA Voyager 350 GaN amp arrived and stone cold blew away the EVS 1200. I have trouble including GaN in the same category as the non GaN class Ds as it is IMHO, on another level.
