I think cables can make a slight difference especially if those low powered amps are SET's. Also seems like the thinner the dielectric, the better.
Cardas makes/made a special cable for this type of amp called the SE-X (X depending on gauge).
They were copper and one thing they all had in common was a very thin dielectric. I used them and liked them. I now use silver wire with a teflon coating.
The theory is: the lower the soakage (absorption) of the coating (dielectric) the less smear will end up at the speaker.
Theories are nice but let your ears decide.
