Newbee has it right in my view. Gold does not oxidize; that's one of the reasons why it's used, that plus its' conductivity. If it's darkening, it could be a build up of some of gunk which can be cleaned off with something like Caig Progold. Otherwise, the gold plating has simply worn off. As you probably know, one of gold's other characteristics is that it is very malleable. It can be stretched very thin. Some gold plating is only a few atoms thick!
How to Preserve New Shiny Banana Speaker Ends?
I've had the Nordost Blue Heaven speaker cables for more than 5 years now and the banana plugs have lost their shimmering gold finish. I have never cleaned those plugs within these years but just lately bought some Progold cleaners hoping to bring back the glitter but alas...I realized it's too late as oxidation has taken its course. The previously golden plugs now looked a bit black and don't look too good although soundwise is not an issue.
Since I've recently bought a brand new pair of SPM speaker cables, I am hoping to preserve the banana ends to their sparkling gold condition as long as I possibly can. Will cleaning the plugs periodically, say once a month work? I just hate to see them turn black.
Your opinions are much appreciated. Thanks in advance.
