Right. Silver and copper actually both conduct better than gold, but gold is much less vulnerable to oxidation. The degree to which the metals conduct is not necessarily related to sound performance in audio cables, and is likely to be in itself not the issue with digital cables either. The primary issue with digital cables is impedance mismatching at connection boundaries, causing signal reflections (you want close to perfect impedance matching). In analog audio cabling, a primary concern is capacitance and inductance, values which depend among other things on the geometry of the current flowing inside of the wire and the properties of the insulating material, even more than the metallic makeup of the conductors themselves (you want low capacitance and low inductance).
Ergo, go to Blue Jean and get some relatively inexpensive, yet high quality cables. I think some people way back on the xx71 thread had trouble with a few of the Monoprice ones, but Blue Jean were very well regarded there.
Anyone able to turn off the fan in their 40A650?
