Exciting news Mark! I assume you're still waiting on the SDS, or was it a failed experiment, as your above statement seems to imply? Did you remember to ask the sparky if the electricity meter was connected in parallel or in series? If in parallel, how does it measure electricity consumption? Does't most electricity passing through your house get returned anyway - apart from what gets converted to another form of energy?
A word to the wise: I know that Mark is not exaggerating in his latest reports, although I haven't been there to witnesses the more recent mods myself. I know because I have witnessed the previous improvements. Furthermore, I have observed miraculous improvements in my own sound systems. I have made even more tweaks to the B&W speakers reported on above, and the results are so phenomenal that they completely transcend any rational world experience. While the sound obviously isn't on a par with what the Kii Three was producing when I was last in the bunker, when you consider the starting points ($800 vs $25,000), then the transformation is more stupendous with the B&Ws. However, when I play sixties garage on them, I have never heard ANY sound system reproduce it so sweetly, so well balanced, and with so much body: not even the Kii Three when I last heard it.
