Out of curiosity, I'm wondering if you have had an opportunity to audition any other power cords in your system. I ask because when reading your original question it sounds as if you have not experimented with other power cords.
I'm not saying that Nordost power cords aren't good, but what I'm wondering is if a different less expensive power cord ($500 or less) would accomplish your same goals. If you wanted to share your location perhaps someone in your area would be willing to lend you a few after-market power cords.
