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.
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!
