I'd go with the top-of-the-line Siltech power cords. VERY expensive, but worth every penny. You might even want to get a bulk spool of the Siltech, and have an electrician run it from your outlets all the way to the breaker panel.

Specifically the reference or ref xl vs Shunyata or Electraglides? I'm using all Trans. ref cable between components and speakers...Thanks
