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?

a way to answer this question:

create two sets of connectors. coat one with gold and leave the other uncoated. listen and then form an anecdotal judgment.

does anyone really care ?
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 :-)
