I really like the Purist Dominus Powercord on tubed equipment. My favorites are the Purist and Virtual Dynamics for tubed equipment, with the Virtual Dynamics having more bass punch, if needed. Both are cleaner and have a more correct tone quality than many others including JPS, Legenburg, Audience, Z-Cable, to name a few.
The Legenburg is very good in A/V systems, including the video screen. Especially good is the Silver wire Legenburg on video screens.
Solid State and Digital is a different animal when it comes to powercords. You might want to try the JPS top of the line, NAT Audio, Elrod, and Alan Maher Designs.
I can't comment on the KS powercords, but their interconnects are very good.
