Although it looks more like a power conditioner than just a power cable, it's hard to fault the sound of a Core Power Tech 150, which Mark at CP sells occasionally for under $400, closer to $350. I use one on the TRL DUDE preamp, and another to take power from my Synergistic Research QLS-6 strip to the Maestro outlet. Each made a significant difference in the overall sound to more live and real. with detailed & organic sound. To be honest, I haven't heard any of the really high cost PCs over $1000, but do have a Dynamic Design Spirit II that was $900 when I bought a demo from DD for $475 that powers my Modwright 5400 CD/SACD.. The CPT cords are much more real and involving sounding than it also. I still like it enough to keep using it in my system. It gets the benefit of the CPT-150 as all my front end components are run through the QLS-6 into the CPT-150.
