Interesting, rhodium or nickel on the XLR, I couldn’t see the RCA, looks gold plated or copper (to shiny for copper). Parts are 8-10 dollars, I could see 75.00 including labor and the tidy little ground lead.
I did a couple of silver plated (the pins) XLRs and RCA, with #18 pure silver low strand count, teflon cable. I used them on Dayton plate amps. The RCA were to close and the run to far. I used XLR cable on a 30ft run, shield ground on one end. Quiet as a mouse. For the shop. Perfect. 20.00 each I think. Still have them. I know they would cost 500.00 each.. LOL I’m to frugal.
