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.

Hum level depends a lot on the system and installation, including "noise sources" in your area. It might just be the case that in your situation you need a shielded cable for such a long run. Check if that Vampire set is shielded before you start writing checks...
