Something is wrong. I owned the 500.1s for about 2.5 years and they were dead quiet. Do they hum with no inputs connected?
Cary SA500.1 mono blocks
I just added the 500.1 mono blocks and I have a hum on both that I can't get rid of .I've tried to lift the ground pin on the PS audio AC12 power cables with no change. I tried different power cables with no effect. The amps are on their own 20amp circuit plugged into a Richard grey 400 . Any help would be appreciated thanks .
