How to eliminate noise in IC's?


I'm running 4.5 Meter lenghts of Vampire unbalanced IC's with RCA connectors. I get a buzz out of the speakers. When I lift the ground to my Parasound JC-1's the buzz isn't as loud but still there. In my set-up I need to keep the IC lenght. I tried a balanced IC and the noise stops. The only problem is my preamp is only single ended. one of my questions is will a single ended out of the preamp to a Balanced XRL into the amp eliminate the buzz? Any other solutions would also be helpful.

Is the system connected to the TV? If so, remove the coax cable from either the cable box or the TV and see what happens. If the hum goes away, lift the ground on the coax cable and you should be fine. If you do not have the TV connected to the system, simply try another set of ICs such as the others have suggested. A defective cable, usually at the termination, will often cause hum through the speakers.
