Silver has a resistivity of 1.59x10-8 and conductivity of 6.30x107
Copper is 1.68x10-8 and 5.98x107, respectively. In other words, you absolutely will not hear a difference but your easily suggestible brain may tell you otherwise.
If you believe otherwise, you'll need to replace ALL the copper wiring in your components and speakers (coils, chokes, etc) and house and power company etc, to get the best sound. Don't forget the windings in your cartridge!
