I also agree that The Cable Company would be your best bet in finding power cords that suite your system. I have had power cords from Audience (very good), Shunyata, Dream State, MIT, and others. In my all Synergistic Research system I choose the new Tesla power cords following Synergistic's excellent power cord to component matching advice.
As Dave_b and Blind Jim suggest, try before you buy.
