I've had the Maggies for 7 years now (which is forever in this hobby). I'm trying them now in the smaller room. First impression isn't too bad. The room has some nasty bass modes, because the length and width are similar in size, so they double up the bass modes around 63hz/126hz/etc. I think I'm going to have to invest in some big-time bass traps, e.g. RealTraps (which are GREAT, if you haven't tried them.
Of necessity, the Maggies are well out into the room. I tried with my head back against the rear wall, and didn't like the sluggish sounding bass. I'm now rotating walls and trying differnt layouts, including diagonal. It's really near-field listening as I'm only about 6'-8' from the speakers, but the imaging isn't too bad if they're toed in more than I used to have them. The image is well behind the speakers, and well-centered. I don't hear the speakers themselves at all, my attention is on the musicians behind them. Interesting!
Restock & JohnK, you make a good case. My issue with single ended has been the total inadequacy of producing convincing symphonic music with large orchestras. I've heard some spectacular demos (at a NJ high-end show), but they were playing chamber music or jazz. As soon as the Mahler or Beethoven symphonies hit, the musical threads all seem to merge, or get lost. Maybe the state of the art has progressed further. I certainly have limited experience, and would love to be proven wrong, but that's my impression.
The room sucks. Like listening to music through a comb filter. And planars cancel their side waves, and load the room differently for bass too. Anyway, I'm not as unhappy as I expected, but expect to do a lot of trial and error. I still may end up auditioning alternative speakers, but for now I've got plenty of things to try.
Thanks again folks!
