Fatparrot makes the key point here: balanced interconnects were specifically designed for use in recording situations, where the length of the cable could be significant. For short runs under 2 meters or so, unbalanced interconnects are usually fine, but for a 30-foot run, I second Fatparrot's recommendation to use balanced IC's.
Does the length of an interconnect degrade the sou
My main system is in my living room which is about thirty feet from my den where I have my home theater system. I want to run a 10 meter length of interconnect between my sacd/dvd/cd player in the den to my main system. Will the length of the cable degrade the sound?
