Cables for Dynaudio C1 Sig

I was wondering if anyone had any experiences good/bad with speaker cables for the Dynaudio C1. I have a McCormack DNA-2 amp. My current cables are Goertz MI-3 which are 7 AWG copper. I bought them based on feedback for use with my Thiel CS6s. Don't know if they are a good match for the Dynaudio or not. They seem to sound OK but was wondering if there is a better match.
