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.

Same trouble two locations,two different cables.
Plus cable is making ground and dropping noise level.
Are there many light dimmers there?

Yea I have some also the one location I have a monster 5100 power conditioner and a power max on the other one is all tubes the other is all solid state. Wondering if it is the innerconnects? do other peoples amps hum when just a long interconnect plugged in.

Regarding the length of you interconnects, I've always been advised by the brick and mortor stores that this is too long. I've listened to several systems using lenghts greater than this and have since changed my mind. In all the cases where long lenghts were run in a carefully laid out system it sounded great. If you have tried lifting the grounds, ect. without success then I would suggest turning things off around the house until you've found the culprit. Florescent lights even in another room can contribute to hum. Good luck.
