I do feel, however, that there may be a cumulative and synergistic benefit to using the Audience products across the board--though I have no way of knowing for sure and am not about to experiment with other brands to find out.
The insidious nature of your cable discovery is that you WILL experiment further, despite your firm stance at present. Trust me, you will. Everyone I know who has discovered the benefits of upgraded wire has followed the same path. It's part of the adventure.
I will say that one day, when you get the itch, you should audition some Purist Audio Dominus power cords, and Venustas and/or Aqueous Anniversary interconnects. I have no connection with Purist Audio other than complete satisfaction as a customer. As good as the wire was that I used previously (I have used Audience, BTW, and really liked it), the Purist wire is in another league. IMO, of course...the usual audio hobby disclosure.
Have fun. let us know if you cut open that Audience PC. :)
