Hbrandt,
Don't exactly know why you are going so gung-ho on using "audiophile" in-wall wire for your dedicated lines. It seems to be a wasted expense - this was my gut feeling & it seems to be verified by several other members.
I think that Belden in-wall cables just might do the trick. I doubt that it is much better than the plain-old Romex wire that electricians usually use. My friend bought THHN wire from Home Depot to do the re-wiring for his room & he is happy w/ the results.
Subaruguru sells some reasonable DIY power cords, in-wall wiring (from Belden, I think) & other AC power stuff that might be of interest to you. Here is a link to his ad:

Of course, JMHO. YMMV.
