Both cables you are considering are fine and I think you would find them more similar than dissimilar. Considering that out of all the cables the speaker cables have the most impact on the sound you might want to go up one more level taking into account the gear you have. I think either the Audience Front Row or Cardas Clear Clear Beyond will give you just what you are looking for and more. I have auditioned both in my system and went with the Cardas as I liked it just a little better but it was really close.
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.
