speaker cables for proac 1sc

I have a wadia 830 running direct into a cary super-amp sig. with balanced cardas gc interconnect . Anyone have suggestion for speaker cables under $600 used. the system can sound bright at times thanks
Hi Davidbrown, the Coincident speaker cable is in this price range and it might be very hard to find better for the money. Good hunting.
I am using Transparent Audio Ultra 12' with Proac 1SC's, Wavelength Audio Duetto 300B amp, Audible Illusions L1 pre. They work wonderfully, but are expensive! Found mine used for $700, even though they retailed for $2400. Good luck!
