Tice Audio Speaker, IC's & Power Cords Any Good ?

I own Pass labs x gear, pre and pwer amp, B&W N802's. I have a freind who own Jeff Rowland gear with Avalon ARcus speakers. He used to own all Transparent Reference power cords, speaker cables and interconnects. He said that the tice gear is better than a lot of ridiculously priced cables out there. What do you experts think. Has anybody have any esperience with the stuff, anybody own Tice speaker, interconnects or Tice infinite Speed Power cords.
Is this stuff really state of the art. I did acually hear the Ic's in my system and they did sound pretty damm impressive. Please comment.
