silver is highly conductive,
it does not interfere with copper's behavior when under any given load,
Silver's oxide is conductive,
silver's oxide does not change the impedance spec in the gross or the minutia of the cable's possible loading scenarios,
it protects the copper from aging and oxidizing (breaking down, etc) in complex varied environments.
These things make it last a long time and work well under very widespread conditions.
Thus the mil spec of silver/copper wire. It says nothing about sound qualities, as you might imagine. Neither here nor there.
