Speaker cables of cooper, or silver :Pros/Cons


I have heard the comment many times on AG that speaker cables,and ICs made of silver sound analytical and bright whereas,cables made of cooper are smoother but less detailed,(or warmer) Is there any truth to this claim?? What about cables made of "platinum", or other exotic materials?? From personal expereince Analysis Plus Oval 12(cooper) speaker cable after a long burn-in period did sound smooth and musical. The Audio Magic Spellcaster 2 interconnect(silver) was bright, but possessed excellent dynamics and detail.

To clarify: "Cooper" cables are made from solid lengths of rusty barrel hoops, look bad, mess up your floor, and sound terrible.
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?
