Silver is 6% faster than copper, you think that doesn’t change the sound?
Really? Silver may have 6% lower resistance than copper, when compared by volume, but do you really think that makes the signals it conducts travel 6% faster?
Electrical signals travel at close to the speed of light. Copper is entirely capable of transmitting Giga-Hertz digital signals, for example high speed Ethernet, using thin, unshielded, twisted wire pairs.
Maybe you think that halving the resistance of a copper wire (by doubling its cross-section) doubles the speeds of the signals it carries? No, it doubles the current it can carry for the same voltage drop.
Pure copper, because of its softness or malleability, makes an excellent connector but does tarnish over time.
