Speaker cables and power cord for Devialet 170

Wondering what others experiences has been. I am using Nordost's Tyr 2 speaker cables and Shunyata's Tron Python for PC. The Shunyata PC sounded better to me than the Valhalla and Cardas PC. But with speaker cables I preferred The Nordost Tyr2 to Transparent Reference and Cardas Clear M.
