Shunyata Zitron Cobra AC Power Cable?

Has anyone tried the new Shunyata Zitron AC cables. What are your impressions compared to the older Shunyata AC products, if you have upgraded. I saw only one post with some information regarding the new series of Shunyata AC cables. Also, where can you buy one? I do not see a dealer network listed for the US on the Shunyata web site.

I need a very good mains cable to plug into an Isotek 8 way. Thanks in advance.
