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

I've been extremely pleased with the Silver Resolution from Signal Cable. They have a 30 day in home return policy, so you could test them out and send them back if you decide you'd prefer to look around. Four foot bi-wire runs would cost ~220. You might be able to find another option that sounds as good at the top end of your budget, but I don't know that you'll improve upon them without exceeding it (unless you go used).

Good luck
I second the Clear Day Cable Double Shotgun. You can demo them for free for 30 days. You will not be disapointed.
'IMHO 7-8 feet is required foe SC's to sound their best'

Have you found this to be true with all cables? I thought that shorter was better. My runs are 6 ft, which is why I ask.
Trial and error over decades convinces me 8 to 10 ft is optimal for most speaker cables.
