Speaker cable suggestions


I am just starting to play with speaker cables. Does anyone have suggestions for an anthem integrated biamped with a Parasound HCA 500 running to Paradigm Studio 60's? The anthem interated powers the midbass/midrange, and the parasound is powering the tweeters. I am using Straightwire Rhythm right now. Thanks for your help.

Just so everyone knows, I am not biwiring here, only biamping. I could use the same cable on tweeter and midbass, but I have different amplifiers on each. So I have to find cable that works well with both amps. Currently I am working on the midbass cable, once that is complete I will work on the tweeter cable.
