Hi John
I also have the Cremonas and understand how important it is to have the right associated equipment & cables to make them really sing. It sounds like your willing to spend whatever it takes to find the right cables. I certainly can't make a universal recommendation here but I'm very happy with my LAT ic's & speaker cable in my system. I would strongly urge you to check out this link concerning the hi-end cable market http://www.latinternational.com/index.php/home/cable%20hype%20%26%20demystification.html. It will be worth your time. LAT offers a 45 day trial period money back guarantee on their cables.
