Acoustic Zen vs. Nordost

I am thinking of changing my Acoustic Zen Satori speaker cables for Nordost Red Dawn. I am not at all unhappy with my present setup, but I am wondering if I could bump it up a little.

My system:
Dynaudio Contour S3.4
Krell 400xi
Meridian G 08 CD
Red Dawn Interconnects
Listen almost exclusively to classical music.

Any thoughts would be appreciated. Thanks.
