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.

Just a thought, if I remember right the Kimber Hero is not a shielded cable, is that correct. Not a good idea to have those long cables hooked up only to the power amp and not connected to the preamp on the other end, I wouldn't push my luck with that test. If you have to have that long of an IC you might try a shielded pair.
