Kimber Kable new series... Naked!
As I understand it copper atoms migrate into and through the gold plating and appear on the surface, where they react with air to produce oxides of copper.
The failure mode for gold over copper printed wiring board ‘card edge’ connectors is high contact resistance and ultimate failure over time.
I know that gold over copper is a popular wiring choice for high end audio cables. I don’t know if there is a corollary failure mode.
At least Kimber has their metallurgy straight, which is a really good thing. Plus Palladium sounds more exotic than mere Rhodium.
