From AES (Audio Engineering Society) copper has a 100% rating, silver is 106.
To clarify, that refers to the conductivity of each metal, for a given length and a given gauge. Conductivity is inversely proportional to resistance, and is numerically equal to the reciprocal of resistance (i.e., resistance divided into 1).
Resistance increases in direct proportion to the length of the cable, and decreases as the thickness of the conductors in the cable increases. Using a cable that is one gauge size thicker would reduce resistance by a greater amount than changing from copper to silver.
Also, any correlation between power cord resistance or conductance and the perceived "speed" of the sonics produced by the component would be unpredictable and component-dependent, IMO.
