FWIW I did the test of disconnecting all IC's at the amp not the source. I switched the power cable from one outlet to another.
I do seem to have more noise from the speaker nearest the outside wall.
My question is - If the sound is not amplified by the amp (volume knob has no impact) is it likely that the speaker wire is the problem?
are ferrite rings on the speaker cables a possiblity?
