gold interconnects and speaker cables

has anyone tried cables made entirely of gold conductors ?

if so, who sells them, how much do they cost and what do they sound like.

i would like to audition a pair, but have been unable to find a company who designs all gold cables. i have seen and hear gold alloy cables, but never all gold cables.
What's the motivation in using gold? It's not a great conductor compared to silver and copper.
BTW most gold comes in alloy form. Pure (i.e. 24 karat) gold is extremely soft.
