I have tried both and am not a big fan of either. Quick summary is that Cardas is better suited for an analytical system that can veer towards brightness, while SR is better for darker/laid back systems.
I would follow the advice of others...call the Cable Company, get some recommendations from one of their salespeople, and then borrow the cables they recommend for your system from their "lending library". If you don't like any of them, just return them at no cost or hassle.
