Speaker cables of cooper, or silver :Pros/Cons

Copper is less expensive than silver.
Silver is more expensive than copper.

why have you not considered gold ?

SILVER, DEFINITELY SILVER!! BUT NOT JUST ANY SILVER CABLE----!!!!

I just tried the most amazing cables, from a small Mexican company, family owned, called Plasencia & Hijos, (plasencia & sons) , they only make 2 types of RCA silver IC's, I have been an audiophile for 3 decades, have tried many many brands, both copper and Silver, I agree to other post regarding the overall qualities of both meta.

Until I tried the P&H Blue Silvers, very affordable price/performance ratio, they keep a minimalist approach , keeping things as simple as possible, but with some interesting approach such as solder less RCA plugs, according to their website, solder degrades conductivity and copper , no matter how pure, starts to oxyde from the day your cables are manufactured. Instead, Silver Oxide becomes a better conductor than silver it self, So in order to the signal flow properly, you got to help it by taking off the equation things such as solder.

These are the best silver IC's I have ever heard , regardless of price.

Too many variables to make a definite statement about silver and copper.
The conductor gauge, dielectric material, alloys of gold/silver, etc., cable
geometry, quality of connectors, quality of solder/weld, specific application,
whether burned in on burn-in device, cryogenically treated. Demagnetized,
destaticized, elevated. These are just some of the variables. You would
think that silver, being the better conductor, would always be better,
wouldn't you?
