I run my Zu Druids with about 25 watts (First Watt F4 clone) and dynamics is one of the things they do best. I would call them "organic" if not the last word in "refinement", but the new '08 drivers are certainly refined enough for me. They do a great job with chamber and folk due to the simple crossover. My room is about 16'x19' and they fill the space nicely even without a sub. They're not quite as slender as your Arros, but can go close to the wall if need be.
Not everyone's cup of tea, but certainly worth a listen. I've very happy with mine.
