If you are going to actually place the speakers within 12" of the front wall and not have the freedom to move them out at least 2-3 feet from the front wall, I would try very hard to get a home demo.
I have the 1027 Be's & am quite happy, but I have found that they are rather picky about placement in my 16x24x9 (and somewhat "live") room - just an inch or two one way or the other can make a big difference.
Also, I suspect the brightness you describe is more likely due to setup (position and/or electronics) at the dealer than needing breakin, although they do improve with some hours.
