Woots, the brand of balanced signal cable is up to you. As long as you choose a balanced cable and not an RCA cable. However, I say that only if your preamp has balanced outputs (many do, in addition to RCA outputs) and your amp has balanced inputs. If your amp does not provide balanced inputs than this is a moot point. If that be the case than you are back to maintaining the amp close to your preamp and having to run long speaker cables. Not the best solution, but for whatever the reason is that you can not locate your electronics in the same room/area as your speakers, you are pigeon holed into a long run of speaker cable.
