In my home office, which is a little bigger, the best sound I have had in there was with the Maggies and a SET/single driver system. I tried many 2 and 3 way dynamic speakers that cost many times what the Maggies cost and it just didn't work.
I think it's partly because the reverberant field plays such a huge part in a room that small. When you have the sound of multiple drivers made from titanium, kevlar, whatever, bouncing all around, it's just something I didn't care for. That's what led me to single drivers fed from a SET. I actually prefer that sound to the Maggies in that room.
Seeing how you already have the Bryston, I would opt for the Maggies. Maggie + Bryston would make a good combo. Single driver + Bryston,,,,,,not so much.
Your goal is the best sound in "that" room. Even if the Maggies aren't optimal in there and may do much better in a larger space, they may get the job done the best.
