I’ll throw in an alternative -
sell all your adcom stuff. Pick up a Rogue ST100 amp and RP-1 preamp (has amazing phono built in). The ST100 in triode mode will be excellent. And total amp and preamp would run about $3500 ish. Will beat your adcom. I know because I had Adcom amps and preamps and had the Rogue components I mentioned above. It will be a significant improvement.
