it is at the speaker. i ran the amps for 3 hours today and the hum was lower than it was last night after being on for 8.
buzz/hum what is going on here?
I have a pair of monoblocks in a 2nd system (Counterpoint Sa20s) and run them off separate dedicated circuits, use PS Audio Power cords, have the grounds cheated, etc etc. If I leave the amps on over 8 hours, one channel(monoblock) begins to hum. The hum does not get louder as more volume is added. It is not audible over most music, but can be heard during quiet passages. If I shut down the amp and restart within a short time, it is still there. If I wait overnight, it is gone. Im puzzled.
