@deep_333 Found this in your Equipment list....Amp 3: Technics SU-R1000, This is Class D no?
That amp is class D-ish no matter what the white paper claims, but, it is not a 1 trick pony (like the loads of class D-umb that’s being sold)... has a few other tricks up its sleeve to deal with certain speakers. But, I have to put it through Masterclass, PEQ, etc on the front end to make it work for my ears. It is also over-engineered/built from scratch in Japan where I gave it a pass on price (no mass purchased foolery there).
In any case, i wish all the guys with purist rigs great luck as the sterility of class D takes over to maximize manufacturer profit margins.
P.S. Try the Schiit Tyr class A-ish topology for a measly 3200 dollars and let me know which class D crap priced way higher sounded any better. Schiit shall set you free.
