tomthiel,
I completely understand your perspective on power cables. I've been a cable skeptic until recently and have mostly avoided diving down that deep black hole myself. And I don't want to get a big cable discussion going in this thread. But since you brought up the shielding issue in power cords, I'll just mention the limited info I've been told by cable advocates. What I've been told is that a shielded power cord is a good idea for DACs and other components that generate a lot of digital noise, but that shielding is not always necessary (and possibly not even desirable) for cords on power amps. The Forte F3 cords have some shielding, but Audience says it's designed to work well even on high-power amps. That claim may just be marketing, of course.
Maybe sometime, when your mind is calm and not overburdened with thoughts of too many other more important things, you'll borrow a low-cost high-value power cord like the Forte and give it a try on your DAC/Pre. For a guy who can hear differences between caps in a speaker crossover, a quality power cord may offer you a few interesting sonic surprises.
On a more important issue, I'm really looking forward to the point when your upgrade kit for the 2.2 is ready for distribution. Best of luck with that effort!
