Any good bi-wire speaker cable (used)..

For around $200 you can get a new pair of close out 1999 MIT Terminator 2 Bi-Wire at AudioAdvisor. Or check eBay for used.

AudioQuest Type 6 or Indigo. Also, if your system seems more laid back than you prefer, Kimber 4TC.

I have a 8' pair of Analysis Plus 12 bi-wire setting around unused if you can stretch your budget a little. Don't think you could do much better for the price.

Zodiac I just tried to email you, but it bounced undeliverable. AGon doesn't like for us to plug our for-sale's on the chat's, but here ya go, since I tried the 'right way' which failed. I have a 20' pair of used good condition Audioquest Crystal 2 biwire shotgun with spades available presently. List new was ~$560 (I think - would have to verify the exact figure) I was asking $275 before A.Q. recently updated their whole product line. No takers, so I'm willing to deal if you wish to make any reasonable offer I'll consider. You should have posted your request under the free "wanted" ads (maybe you've done that I dunno?) might get more responses… good luck
