Any really good power cables for a Plasma HDTV ?

I have a Pioneer KRP-500M plasma and want to upgrade my stock cord. What's a good one to try out?
Shunyata Python Helix VX. It does wonders for video quality and clarity for DLP, Plasma, LCD, DirectView CRT, etc...(have used it on all 3 types).
Has anyone tried the new CX series from Shunyata ?
I might try some all new Infinity strings power cables from Alan Maher Designs later on
