Audio Research LS 17 SE Power Cord

I'm looking for power cord recommendation's for an Audio Research LS 17 SE.  I was looking at something in the $500-$700 range.  Two cords I was thinking about are the Shunyata Zitron Viper and the new JPS Pac Black.  I currently have Acoustic Zen interconnects and speaker cables, so their power cords could be an options as well. 

Any insight would be greatly appreciated.   

Thank you.
