Gold is a good but not a great conductor of electricity. Copper and silver are better. People assume gold is better because they see it being used in electronics, but that has less to do with its conductive properties than gold's ability to withstand tarnishing or corrosion. From http://www.mains-cables-r-us.co.uk/blog/2011/11/20/the-conductivity-of-metals-used-in-hi-fi/ Even this chart is based on pure gold. Gold alloys have far poorer conductivity than pure gold, and so the diff
