From the Roger Russell screed on everything you never wanted to know about audio cables:
KIND OF WIRE MADE NO DIFFERENCE
It can be solid, stranded, copper, oxygen free copper, silver, etc.--or even "magic" wire--as long as the resistance is kept to be less than 5% of the speaker impedance. There is no listening difference as long as the wire is of adequate size. Bear in mind, as previously mentioned, a well-designed amplifier will not have a problem with any of these wires.
That's terrific. Now I can stop worrying so much about the coat hangers I'm using for cables.
