Where to buy quality phono connectors for chassis

I wouldn't hang my hat on "gold plating". It looks nice and won't oxidize, but it is not necessarily the best finish for sonics. It depends more on what major structural metal is under the very thin gold plate.

Check also with Michael Percy Audio. He sells all the Cardas variants plus Vampire. Also, I bought some that are either made by Eichmann for their bullet plugs or are sanctioned for use with them; maybe from Percy or some other US source. It should be no problem to find high quality "female chassis mount RCA jacks". (That's what you are looking for.)

Not that I can intelligently debate the issue, but I had come to like the Cardas female RCA jacks that are brass under silver under rhodium plate, rather than gold.

But since then, I also like the less massive female RCAs that were sold to me when I asked the question "What female chassis mount connector goes best with an Eichmann bullet plug?" Without question, my favorite male RCA plug would be the Eichmann silver bullet (copper, too). I am not entirely sure that Eichmann makes the female jack that was sent to me, but it does work well with the Eichmann male plug. (There were four in a box set, but I discarded the box before noting the brand.) I cannot tell what they are plated with, does not look like gold or rhodium. Might be something over copper. I mentioned Vampire brand; those look good to me too and are cost-effective. The ones sent to me for use with the Eichmann may well be made by Vampire.

I've kind of made a decision not to fret over RCA plugs any longer.
