I'm looking forward to reading your results and journey there.
I have a couple of questions regarding a gtg setup. Based on some personal sighted A/B tests I did a while ago with some bookshelves I noticed some things. Their "ideal" positions, based on their interaction with my room and listening position, were slightly overlapping. It was not possible to listen to each in an A/B switching setup without physically moving them to their optimal position (room boundry, toe in, etc) and the other slightly out of the way.
How do you plan to address this in a GTG setting where speakers live behind a curtain? I guess how fussy are you with setup and ensuring the speakers are judged on ideal setup? This has always been my biggest gripe with shootouts and GTG setup stories. But I have no idea how to accomplish an ideal test with ideal setup. ::shrug::
