I read about the Outlaw RCA cables and the special copper and all that. But I find it's impossible to know just how one cable compares to another. It's not like amplifiers or something where you can use the specifications, power, THD, etc... to compare. How does one compare price and performance of cables? The Outlaw cables look very nice, but how do I know that they are any better than $10 cables that I buy at Circuit City? I mean really! Greg
