Hmmm - I think you're probably scraping the same barrel that he does. In any event, there are far far cheaper ways of getting a low impedance mains supply than by using his magic cable!
A very fair point in the context of home audio, John. I must admit that my mind had drifted off-topic towards amplifiers I'm used to using at work, some of which have a peak demand in excess of 3kva for short periods. The only requirement I have for the power cables on those is to be of large enough CSA!
