Need advice on speaker cables

I'm currently in the market for speaker cables, new or used, and 8 - 10ft length. I can probably budget $1500 - $2000 for the pair. My set up includes a Cary V12i amp that powers a pair of Spendor 1/2e speakers. I have had good luck with Nordost interconnects and would consider them for the speakers as well, but would like to get some other opinions before making a decision. Any advice is appreciated.
