I did what I said I would do, and finally, this one-man jury has reached a verdict.
Conclusion: In all the A/B tests and experimentation I've conducted since my original post, I have arrived at the answer that in my system, high-end power cables connected AFTER the AC regenerator (i.e. from the Purepower 1050 to the preamp, another to the amp and one to each of the source components made a significant and immediate improvement in midrange clarity, bass articulation, depth, and shear musical impact.
On the other hand, anything I installed in the chain BEFORE the AC regenerator (i.e high end power cable from the wall to the Purepower 1050, high-end wall receptacle, as well as a 20Amp dedicated line that cost me over $500 -- made absolutely no audible difference at all.
My expensive conclusion is that the PurePower 1050 is doing exactly what they claim it does no matter what crap comes out of the wall, be it dirty power from the grid, erratic voltage drops or spikes, whatever, it doesn't seem to matter -- the Purepower doesn't care -- it strips out the grunge from the AC by converting it, waxing it, polishing it, and generally having its way with it to create brand-new, virgin, perfectly shaped sine-wave, completely steady 120V AC with copious headroom reserves for instantaneous availability to all components. This unit has transformed my system in so many ways. Aside from the usual inner micro details that have emerged from the deep, music is much more dynamic, richer, with faster attack than I've ever heard.
No I'm not on their payroll, just a happy customer. This is the best $2500 I ever spent upgrading my system. See if you can borrow one somehow and hear for yourself. And please, don't lump this remarkable product in with power conditioners and filters, no matter how expensive. This is a different animal altogether. If you have any questions, please ask. Alonski out.
