I have recently started playing around with 2 pairs of Audioquest Cheetah I/C's. One thing I know for sure is that cables do not make the same sonic signature in any two systems. They do not even deliver the same sound when moved around in the same system, as Audphile1 seems to have found out. Cables are a way to EQ the sound coming out of your speakers. Silver may or may not work for you. I am still moving them around to see what I like best.
