I think an obvious recommendation would be a speaker cable from Kimber. Considering the quality of your system and the level of your Kimber interconnects, I would suggest nothing less than 8TC, with Kimber Monocole being an even better choice. You may even want to consider an entry level Kimber Select speaker cable, used.
A second obvious recommendation would be one of Acoustic Zens own cables, which would I assume, would be an excellent match for your speakers.
