is there really a sonic difference assuming resistance/inductance is the same? If so, does solid silver sound different than silver plated copper? I found some cheap teflon coated silver plated copper, but some people claim that the coating does nothing other than help prevent oxidation since silver is not supposed to oxidize at room temps and tarnish is a product of sulfer. On the one hand, it wouldn't make sense to use solid if plated silver on copper sounded as good, but I thought current ran on the surface, and we're bombarded with propaganda that says gold plated terminals are better. So whats the real deal?
