What does everyone think of Zu Cables Wax?

I recently traded my Naim amps for a YBa Passion, and my speakers are Audio Physic Virgos. I need to find speaker cables to replace my Naim cables. I bough some cheapo Belden wire recently, but it doesn't do it for me, so I guess I am beginning to think that there may be something to cables afterall. I have been considering Kimber 8TC, Oval 9, and Anti-cables. I'm somewhat intrigued by Zu- does anyone have any experience with these cables, aprticulalrly the Wax model.
