Pure Red Copper.

IIRC, Viborg uses what they call red copper, which is probably red brass - a high Cu content brass, quite a bit harder than pure Cu. Visually and under a few strokes of a metal saw (I wanted to check if this is not a plating) behaves indeed like a 'hard copper'. I protect the surfaces I can reach using Paul's method (I 'hate' you for that Paul, takes so much time): jewellery polish (me by hand) - isoprop cleaning - dielectric grease (silicon based DC-4)


If Viborg is following the market standards and I think so, "Red Copper" or "Pure Red Copper" is Cu2O, the first stage of the Copper Oxide. But I don't remember of anything about red copper on Vigorg literature except, may be, on power cables.

Don't really care much
Might be. Honestly I don't care until they sound good. In Paul's construction they do (thank you Paul!)

Drama vs. Economics
Alex, whatever the standards and/or expectations are for steel plate for ship yards, customers for electrical connectors don't want them to start out corroded, starting at the wholesale/distributor level. So, manufacturers don't want an inventory of their finished products corroding, either, and they go out of their way to be sure this doesn't happen. I don't know the specifics of working with copper for the "hi-fi market", but it's easy to see there's not much in the way of pure copper connectors available, and I suppose this is because it's more profitable to work with and sell copper alloys ("eutectic" copper). Hard to believe there is a profitable yet un-tapped market for pure copper hi-fi connectors.


Best regards,
Paul S

I give it up.
So, I give up of trying this cable construction experiment. I found some who already did a test with a similar construction and once a higher shielding material was placed it killed the cotton in oil magic, and it sounded like a "regular' shielded cable.

Thanks for the advise too.

Btw, Viborg has now pure solid silver power plugs.

E.g. http://www.viborgaudio.com/en/Product/a/chanpin/jianzhusheji/2021/0923/377.html

A cable vendor that actually explain what they are doing... if that is BS or not, I can't tell.
