NOW, gold does have the ability of being made ultra pure so has the advantage for some, but the cable are really expensive... Check out the Steath PGS line for an idea.
can't comment on the "science" of gold vs. silver but I do recall that Doug Sax (co-founder of direct-to-disc pioneer Sheffield Lab) used nothing but silver connections (including custom-made silver 1/4" plugs and jacks) in his Mastering Lab setup and, given his well-known dedication to the achieving the best possible sound, we can assume that silver outperforms gold in this context.
