Re: Sort of

I have hum thru system that is present at all times. When music is playing it is barely audible. I have FI 2A3 mono blocs with KCS BLH 98db eff speakers Wright Sound LS and phono. Never noticed this problem when I had PP amps and less eff speakers. I have turned off every breaker in house except main and the dedicated 20 amp breaker system is on. Just trying to track this down, hum still there. I have tried cheater plugs on everything. Amps are new 2 months old. I had some 300B mono amps to try and they did same thing.
