Issue with borreson is resale value can be am issue..has very small presence in usa..2 dealers. In addition, massachussets and illinois are only 2 dealers.  When michael b was with raidho..it never went over big. 
The stereophile measurements show a 10 db boost from 200 hz with a flat response to 5khz then rolling off to -6 at 10k and -15 at 20k. I know measurements only tell part of the story, but don't measurements like this suggest they'll be room dependent more than most? 
My two picks:The Sound Lab Majestic and the Classic Audio Loudspeakers T-1
Set up properly they sound very similar- both are quite fast since both have power supplies to run their diaphragms (the T-1 uses field coils).
You'll need more power to run the Sound Labs. I run the CAL T-3s at home and 50 watts on them is plenty!
