I just took delivery on a pair of Mirage OMD-15 floor-standers a week ago and now that they're broken in, they're just marvelous! In fact, I moved up to them for the same reason you seek to--I wanted something that would move more air in a cathedral-ceilinged open architecture living space, and the 4.5" 2-ways (even with sub) weren't quite doing it.
But the OMD-15s do it in spades, and if my setup is any indication, your little Bryston will probably be up to the task as well. The OMD-15s have a sensitivity rating of 91dB. This is a HUGE increase in volume-per-watt over the Totems, which are rated at 87dB. It would be like upgrading to a 150 wpc amp with your Totem (but the Arro's only rated for 80 watts max; these Mirages are rated to 250 watts).
They're the perfect size--40.8"h x 8"w x 12"d. Bi-wirable/ampable. Tremendous, room-filling soundstage with big sweet spot. With that comes less spot-on imaging, but that comes with the territory with wide dispersion.
These speakers are also plenty hi-rez to show up the quality of your upstream components. I was swapping 4 different amps in and out, trying bi-wiring and bi-amping, and could always tell a difference. The best matchup was an old 70 wpc high current Amber Series 70 power amp, so your Bryston should be a good match too. And if you want more oomph later, you can keep the Bryston and add a power amp and bi-amp the speakers.
The only downside is that these retail at $2500/pair. Crutchfield is an authorized dealer and that's their price. If you need to go cheaper, occasionally a grey market pair shows up new-in-box on eBay for around $1550 + ship.
