Silver vs. Cooper speakers cables

I feel that not enough attention is paid to aluminum.

Good point. I stopped buying soda pop in those copper and silver cans years ago. The copper poured too slow and the silver poured too fast. Aluminum gave me just the right balance.

Wc65mustang, what happen ever happened to your Steath "bomber" Indra cables? What's wrong with "the best" cable you ever heard?

To answer the origonal question(my thinning hair is an issue, but I'm dealing with it) responders have talked about Acoustic Zen, with good reason, a good company, making good copper and silver cable. Not silver speaker cable of course. As others have said more eloquently than I, neither is good or bad, just good or bad in a given system. Cables seem the item above all, that is system dependent.
I bought an AZ cable loom, partly through Audiogoners advice. The specific advise I got was silver ref between CD player and Pre, and matrix pre and power. In fact my system is much better with all silver reference(unfortunately in view of the price). The greatest improvement though, came with the copper hologram speaker cable, truly a major boost.
Pretty obviously as with all areas of high-fi, try it in your system and see what works(remember the cable company has loaner cables for you to try)

Has anyone used Gold cables? If so what do you think about their sonic characteristics (if any) compared to copper/silver?

I'm burning in a pair of Pear IC's presently, and getting some nice results considering <100 hrs of play time. http://www.pearcable.com
There's some interesting information on the properties of Gold versus copper/silver on the above website.
