Black Cat power cables


Hi all - Just looking for feedback regarding Black Cat power cables. Opinions? How they compare to others you have used?  Thanks

I went from a Synergistic Tungsten power cord to the Black Cat Silverstar power cord on my Rowland. Big improvement in resolution, nice increase in soundstage definition and depth and a noticeable improvement in the amps dynamics. Very impressed with the Black cat. 
@twoleftears  Chris tends to re-name his cables fairly frequently. The PC that I own is the Silverstar, although I believe it is now called the PC-1 cable. I also own a pair of Silverstar ic's...which are possibly one of a kind, as I suspect Chris either dropped them after he built mine, or changed the name., probably the latter.
