Thanks guys. All of my interconnects are shielded and I tried a cheater plug on the whole system via my power conditioner. I only hear the hum when I put my ear to the speaker, not at all from my listening position. With every other component turned off the hum was still there with my amp, making me think it's transformer hum.
A quick question?
I know this has been addressed ad nauseum so bear with me. Just got new speakers (Sonus Faber Grand Pianos) and I'm hearing hum when I put my ear up to the speaker. It is definitely from the amp because I turned things off one by one to isolate. I tried a cheater plug but it didn't work. Is this level of hum, very low, normal? My amp is c-j 11A.
