You are welcome Pat. I would be interested in hearing them, since I have owned many of Robert's cables and cords, but I never heard any of his copper cables or cords. I even owned an Alethias! power cord once, but it was also the silver version. All I've ever owned from RSAD was silver. Robert didn't start using copper until the Alethias, which was near the end, when he seems to have disappeared.
I currently own way too many cords as it is now though, so though I am interested in how the copper would sound....I'm not that interested. LOL!! Good luck with your sale, or just enjoy them.
Cheers,
John
