Fuuny I just posted a thread on the Audience Power cord. In my system the cord works equally well on all components.
Interesting comments about the Synergistic Research Master Coupler. That was one of the other cords I was looking at when I found the Audience Powerchord.
Now it is time to try and find something to put on my CDP. The Shunyata Diamondback seems a decent upgrade but certainly on the lower end (price wise).
