Hey Don,
If it works for you, that's all that really matters, right? I have to admit to being a past skeptic, now turned believer in Pierre's often whacky methods. Some of it is really, really hard to get your head (and eyes) around, but he and Ron are eccentric geniuses with impeccable engineering credentials.
I was completely skeptical of their power strip but got to demo one in my place a few weekks ago (one of the "Stratum AC conditioners -- power strip mounteed on a maple block) and was stunned, literally, at the difference. Unfortunately I can't use the speaker wires or interconnects as my cat loves to chew on bright shiny things and plastic films, and it doesn't take much to get that insulation off -- which is bad for the electrical gear, and worse for the cat.
Anyway, back to the subject at hand, I see I had misinterpreted how the FP III+ volume control hooks up, and not that I've got it figured out, I've gone ahead and ordered a 25k 48-step khozmo ladder attenuator and will play with the padding resistor until I find the right balance of adjustability and overall gain. I'm also going to put the resistors between the selector and the pot to keep things simple and reduce the possibility of noise pickup. I don't really need each input to be level maatched as I will have somewhat more than 11 steps to work with. I'm also using a single stereo control and will place it on the opposite side from the power switch.
Problem solved, case closed. :-)
