Why gold?


What is the big deal about coating your connectors with gold or silver?

I just bought a Yamaha M-40 amp that has a clean pair of steel RCA connectors. Am I missing out on some sonic advantages of Gold or Silver lining?

Oh ya, I think the dial on my freezer goes down to about -375f... I suppose that should do it.
I spent a winter in Elko, Nevada. You could toss anything outside over night to cryo it, then toss it in your freezer for a slow warm up :-)

"Gold has a warmer sound, silver more air and detail- all things considered"

- That's what I heard but it applies to material of the wire and not the thin plating of connector.

Audioquest uses silver since gold is not a very good conductor but, in my opinion, it doesn't make any difference in interconnects because of high input impedance and very thin plating.
