I had this same problem with my Hafler DH-200 and any length interconnect. Turned out the body of one of my RCA input jacks had come into contact with the metal chassis. As soon as I got the jack isolated, all hum ceased.

Hum in system from interconnects???
I have some 21' kimber hero rca I am using for interconnects to my quicksilver v4 amps. When I turn on the amps they are quiet till I plug in the kimbers. If they are not connected to my preamp just hanging there the amp hums quite loud untill I plug it in to the pre amp then they quiet up but still have a slight hum in the system. What is going on?
Should they hum if they are not plugged in to anything first off? I have tried grounds power connditioners etc. Is it just the cables is the run to long for rca? This also happens downstairs in my HT with a adcom solid state amp and kimber tonic 21' interconnects but it doesn't bug me as much.
