Anyone own DH LAB Red Wave Signature PC's?

I am curious from anyone that has experience with these power cables what you have tried them on and gotten good results? Amps, Digital Sources, DAC...??

What did you like about them?





Friend swears by them and uses a half dozen to power his entire system. I have not heard them in my setup but it seems like a great option based on his system. 

Prior to that he was using some rather expensive AQ model with the little inline battery power thingy. Replaced those with the Red Wave Sigs for less money and feels they perform better. Make of that what you will.
