But thanks to the skin effect, silver plated power cables should conduct RFI energy BETTER than regular copper cables.
I wasn’t going to respond again, but I’m weak. Eric should be invoking the “damping factor” on this thread soon. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Jun 21, 2016, at 4:18 PM, Jim Brown <[email protected]> wrote: > > On Tue,6/21/2016 3:05 PM, [email protected] wrote: >> its silver plated > > Which, contrary to the hype from ripoff artists in the high futility world > will try to tell you, offers NO performance benefit over POC (plain, ordinary > copper) in even the most esoteric of audio systems. > > There's a classic AES Paper from the '70s by E.E.
