SkiTaos, I guarantee you wouldn't be able to tell the difference between generic 12-gauge "zip wire" and equivalent gauge Kimber Kables in a double-blind test. Passing an analog audio signal is one of the least complicated things a wire can do and is extemeley well understood scientifically.

To sum up, unless a cable is designed in such a way that it alters the original signal -- which is a BAD THING -- then it'll pass audibly flawlessly from one end to the other.

And don't even get me started on digital cable. 1s and 0s in one end 1s and 0s out the other.
