Speaker cables Mid High end

Currently have Kimber 8TC speaker cables and recently purchased a Mark Levinson No.526 preamp paired to Mark Levinson 532h amp and Revel speakers. Looking to upgrade speaker cables and have been looking at Cardas Clear line and also read great reviews on Audience AU24 SE . Looking to buy lightly used and want a neutral, open and a high resolution cable to capture the highly transparent and resolving attributes of the No.526 preamp. Any recommendations and thoughts on the Cardas and Audience are welcomed.
