Mingles -- That was an exceptionally good paper you linked to, by Bill Whitlock of Jensen Transformers. I say that as both an electrical engineer and an audiophile. Thanks for calling it to our attention.
I think it does a remarkable job of explaining why cables can and do sound different, while putting into proper perspective the hype and nonsense that pervades their marketing.
One minor point -- those reading the article should be aware that in several places it incorrectly uses "V" to refer to "ohms," rather than the omega symbol or just the word "ohms" itself. Probably his word processor program taking liberties!
