Anti-Cable Power Cables

Has anyone tried them yet?
Yes- I have a review coming out soon on TNT-Audio.
I love the Level 3 but all levels are well built, afforable and most of all effective. Plus money back guarantee and upgrade program makes it easy to try. I'm not affiliated in any way - I just got done writing a rave review and waiting for it to be published.
Just curious, are they directional like their other cables?
Yes Geoff the power cords are, if you reverse them your amp will supply power to the grid. I guess that what makes them affordable!
