I'm generally a cable agnostic, but I agree with reks here: show us some data. If it's reasonable to take someone's subjective opinion about the differences between silver and copper, then it also is reasonable to ask for data that would tend to support that subjective experience. That people take such personal offense at such requests is telling. There's a certain arrogance to the "Well I heard it, so you have to believe it" camp that I find particularly annoying, and, in the end, lacking in credibility.
