I've seen some excesses in audio that were probably pointless, but gold on contacts is a good choice. Gold doesn't oxidize like other conductors, so it makes a better contact material. It's actually used in a lot of electronic equipment, from computers to hifi and everything in between. Pretty much everything but the cheapest gear uses gold plating on conductors that contact one another by mechanical connection, i.e. edge connectors, plugs, etc.
