Speaker cable advice


I am currently looking for a new pair of speaker cables.
My current setup is a pair of CARY SLM 70 tube monoblocks, a counterpoint sa-3000 preamp, cal icon mk2 power boss, rega planar 3 with an rb600 arm with a denon 103 cartridge and PSB stratus goldi speakers. I am currently running morrow ma2 ic's (great cable by the way) and audioquest type 4 speaker cables biwired. My budget is around $500, and I only need about 4 foot runs. I am considering goertz, kimber, xlo, etc. I would like them to be biwired
Any suggestions?
Thanks

Third the Clear Day Cable suggestion. Plus Paul is a great guy to deal with. With the trial offer, there's nothing to lose.
Don't have your set-up but am very please with Clear Day Cables in both of mine
Skipper....I have a 5 foot biwire stereo run of Anticables if you want to try them
DH LABS Q10 very cheap and sounds pretty if you don't mind a little silver .
