Though I do not own a 507MkII, my close friend does. A power cord can and does make a very hearable difference. We demo’d an older Pangea 9, Nordost Blue Heaven, and Nordost Heimdall 2. It got better as you moved up the line. I’d say the Pangea was not worth the money though because there was little improvement and the sound was still grainy. The Blue Heaven makes a nice difference at $330 but the Heimdall 2 was much better. If you can swing it, or something comparable, that’d be the one to go with. Another power cord that is even better for nearly similar money to the Heimdall is the Isotek Optimum. The Isotek is better value for money to me.
