Find a used Synergistic Research AC Master Coupler, if you want a real improvement in those areas. They aren't that much more expensive, and it's a cable you can keep using when you make further upgrades to your system. Or a Zu Bok, for a less expensive alternative. I've found that every component in my system responds differently to powercord brands/designs(The only two components I own from the same company are my Cary Monoblocks). Each unit in the audio chain has a different requirement, whether current demand or noise/interference cancellation(to or from). I wouldn't expect one cable(brand or design) to fulfill every demand well, in every application.
