What power cord to use with the XA777ES?

I just tried a PS Audio "Statement" pc and didn't like the results, way too bright. The stock cord sounds fine, I'm just looking to tweak it a bit. What pc matches the XA777ES better?
Looks like you will have to try a few cords. Cardas is known for darkness otherwise I have had good results with Pure Note Sigma pc on my Sony SCD-1.
