Pure Silver Wire

@richardbrand while what you say is correct, it doesn't cause silver to preferentially transit one frequency over another.

To the original point... solid silver is expensive and occupie only the top of a cable manufactures line.  My Wireworld Platinum speaker and IC cables are silver and sound wonderful.  The speaker cables are much richer sounding than the Nordost Valhalla 2 copper/silver cables they replaced.  Audioquest's top of the line cables are solid silver and violently expensive but highly regarded for example. 

@coppy777 Well those WW Platinum Eclipse ain’t cheap either! I opted for the less expensive WW Gold Eclipse 8’s and they are really nice.(CONDUCTOR MATERIAL-4N Solid Silver)

Hey fthompson251,

Agreed. The ICs between preamp and amp are actually G.E.8s. I auditioned a pair of Platimums as potential replacements and returned them. Could not hear any difference after a relatively short audition.

Best,

It might change the discussion focus, when debating digital interconnects, from resistivity to the skin effect at megahertz and gigahertz frequencies. 

Of course, the physical topology of a cable also matters.  At low frequencies (speaker cables) two parallel conductors might suffice but at higher frequencies coaxial cables take over until they in turn give way to very thin unshielded twisted pairs.  At higher powers and frequencies, tubes can replace solid rods, and multiple Litz strands can replace thicker wires.

All cable technologies have capacitance and inductance as well as resistance, and these do attenuate frequencies differently!

I wish there was more discussion about the use of aluminium as a conductor ... especially where low mass is beneficial - power transmission wires, speaker coils, moving coil cartridges.
