Gold is a very good conductor, the quality of audio and video passed though it is far superior to a normal cable.
Not sure if you're trolling or not but that statement is full of shit. Gold plating has no significant impact (if any at all) to a digital signal.
As long as you are running the appropriate HDMI Spec for what you're trying to achieve then buying the cheapest specced cable will be just as good as a "gold-plated" or "isolated" cable.
Even if you argue and say that Gold is immune to oxidizing, well again it hardly makes a difference. Gold plating is usually so thin that the gold will wear off faster than a standard tip will oxidize. Even ignoring that, if the female receiver isn't gold plated (pretty much all of them are tin) then using a gold tip cable on a tin receiver will actually speed up the oxidizing of the tin receiver. Tin on Tin is better than Gold on Tin.
