Yep, amen to that. I got lucky and finally found a spot where bass and imaging were both pretty good, but I had to rip out a bunch of living room furniture and lean Roxul panels up against half the windows to get there -- and even with all that imaging is not as good as it was in some of the previous locations.

Your experience with the tube electronics are interesting... I'm still toying with the idea of trying a tube pre-amp to see what difference it makes.
