Try copper cables. This may sound strange but just go down to a Home Depot or a like store and purchase solid copper cable in a thickness that reflects the power or current of your amp, twist the single wires together using about 2 twists per inch,less for thick wire, to bind the pair. Try them out. If you dont like them you can pitch them with a nominal loss. If you like them then try the "Clear Sound" coppers with the copper terminations, I think they advertise them on Audiogon. Or keep them and use a good copper termination.
