Tri-wired speaker cables for bi-wire Audio Note AN-E speakers?


I currently have an older pair of Cardas Quadlink 5C bi-wire cables but would like to upgrade for the Audio Note AN-E Spe HE speakers I now own and love. I'm looking for a used set of bi-wire cables that are at least 5m long (room configuration prevents me from using shorter lengths, unfortunately).  My budget is $2K. There aren't many listings that fit the bill, but right now there's a set of well regarded Straight Wire Crescendo 2 cables on ebay, 20-feet long, that seem to fit the bill, but they are tri-wired, not bi-wired. The owner says I can just leave one set of cables unattached, but I'm wondering if that would compromise sound quality.  Also, if I only need 5m, will the extra length unnecessarily compromise SQ as well? Thank you in advance!

5m's is obviously a very long setup, I think the Kimber rec is a good one. I have AN-J/lx's I am using AN Lexus single wire cables with Kimber 4TC jumpers. The jumpers sound excellent. I'll just say too that a lot of AN speaker owners prefer single wiring with jumpers over bi-wiring.
To the OP, have you thought about using Audio Note cables?  I have seen used pairs posted occasionally.  I am not sure if they could be had in the length and price range you mentioned.  I too would use the jumpers. 
Thank you all for your generous comments. Jond, I'm totally open to it, but why do AN owners seem to prefer single wiring over bi-? Stereo5, yes, I'm definitely interested in the AN cables, just haven't seen anything listed that's long enough, and the retail price is beyond my budget. Tvad and Matt Miller, I haven't tried Kimber Kables but will definitely read about them.  Thanks gain!
