Canyon John,
DCCA has all three of their power cords on auction right now. There are many threads on why a good power cord makes such a big difference, in spite of the miles of cheap wire that precedes it. What most of us non-technical oriented audiophiles don't understand is that the power cord is actually an extension of the power supply. It is easier to understand why it does what it does when you look at it from that Layman's perspective. Have fun in evaluating your power cords. Just remember to give them adequate time to break-in , if new and adequate time to re-settle if broken-in, but unused for a while.
