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.

I have seen this before. Depending on the grounding scheme of the amps, you can get major buzzes from ICs - no matter the length. Getting around the problem may be tough. I had an easy way out with MIT T2 ICs, which never seem to buzz even with my sensitive Kora Aries and so I didn't experiment much on other ways to solve the issue. I would say any shielded cable could improve things but the problem is grounding, as you already figured out. I will think about it and if I think of anything, I will post again. Of course, MITs could solve your problem too. But lifting your ground should work. Hmmmm...

What preamp are you using?
