Silver vs. Cooper speakers cables


I want to know if silver cables are really better than cooper.
Up to the moment I use Audioquest Volcano biwire cooper cables but many people recomend move to silver for my Tannoy Speakers.
Pure silver or hibrid cooper silver ?
AQ silver cables are very expensive, but I can saw that there are many silver cables at very affordable price like Silver Audio or Analysis Plus.
Please let your opinions and recomendations.
Thanks.

Off topic, but Rsbeck's mention of Amazing Randi brought this to mind...

Rsbeck, I'll bet you will love The Skeptical Enquirer . I once purchased a subscription for my Dad, who was the biggest skeptical thinker I knew. I believe Amazing Randi might be a contributing author to the magazine, but I'm not positive.

Back to the copper, silver, gold discussion...
Sorry Rsbeck, but we must agree to differ. I know my system and I know when the higher and lower frequencies are not sounding clear and extended. I'm past the 'it's all in the imagination' argument, so if you want to get into that one you'll need another sparring partner.
Also, I don't recal stating that silver was 'bright', either to look at or to listen to. It may or may not be, depending on other components in the system, and/or how often you polish it.
I can't imagine a three cables constructed from three different materials not sounding different. But that's just me. If there's a measurable difference in the three cables, which there is, then they ought to sound different, albeit subtly so. Maybe it comes down to the quality of supporting equipment, the state of cleanliness of ones ear canals, or just the time of the month for some of us, but there ought to be a difference.
Incidentally, that 1,000,000 would be handy, I could buy some Marigo dots and Peter Belt foils, and really knock myself out.

You said the key word, IMAGINE. If you can only imagine them sounding
different, your imagination will take care of the rest. I believe this thinking is
a holdover from musical instruments where nickel would strings sound
different from bronze, a silver trumpet sounds different from brass, etc.
There's no reason for a silver speaker cable to sound different from copper or
gold, etc. The only meaurable difference between the three is resistance --
you want low resistance -- so if you use thicker guage gold you can match
the resistance of silver or copper and if you do they all sound the same.
There are no other measurable differences.

Wrong
Wc65mustang, Why do you claim that Stealth Indra is the best while you switched to copper? Isn't that kind of ironic?
As far as Bose 901s.. I don't have them.. Used them back in the DJ days in the late 80s.
