That's a pretty good article. I don't have any experience with ultra-high-end cables. But I do know from my own experiments that wire DOES make a difference, in terms of material. That is to say, $20/foot silver wire will not really be better or different than $3/foot silver wire. But silver wire is definitely different than copper wire, and different gauges of any material sound different. The dielectric makes a difference too.
My only complaint (not to be an a-hole) is the guy could have used a spell checker.
