Biwire speaker cable advice, please


I have Luminous Audio Technolgy Prestige 6' external biwires that sound pretty good, though I've tried no others yet. Budget is ~500 or less, used is fine, I can use spades or bananas. I could braid some CAT 5 on the cheap, but a finished cable would be easier on the old digits. The current rig:

G&D Ref 1 xport, Genesis Lens, Timbre TT1 dac, Electrocompaniet 4.7 pre, Bel Canto Celio [50 watt Class A solid state] amp, Impact Technology Ventos.

In advance, many thanks to all for your good counsel.

Try Audioquest Granite, Gibraltar, or Caldera. Each are bi-wire configured, and you should be able to find them on audiogon used or as demos. I've seen some really good deals on them recnetly. They are listed from lowest to highest in price. I'm confident there is no equall for the price.
