I believe that if you add an expensive power cord, it will only sound better (or different) if you look at it. That's why the manufacturers make them look like something NASA would use on a Mars Rover. Once you've looked at it connected and powering your equipment it will sound different because you just dropped a whole bunch of cash on it. Your eye's will convince your mind for you.
This is my opinion based on my ears, but the three things I wish I never bought was very expensive speaker cables, a cryoed hospital grade 20a wall outlet, and after market headphone cord for my AKG 702's. I cannot hear the difference in any of those. YMMV.
