Cardas or Nordost???

Currently I have all Nordost Cables in my system (SPM interconnects and Red Dawn Rev 2 speaker wire) My system is very basic and consists of a Wadia 850 run directly into a Mark Levinson 331. I am thinking about trying out the Cardas Golden Reference interconnects and Neutral Reference Speaker cable. I know these cables are totally different. Any thoughts on what would be the best fit? Thanks in advance...John
