Back to the original posters question regarding amps for Arros and room size, don't let their small size fool you. These baby's seem to love lots of power, the more the merrier.
When I heard them, they sounded very nice in a demo room approximately 35X25 feet, but they were sucking as much power as the hefty McIntosh amp that was being used to drive them could throw at them. To their credit, though they didn't shake the rafters, they seemed to thrive on the power and turned it into clear fully formed music without distorting or breaking up, quite a feat for such diminutive guys in a good sized room competing strongly with other larger and more expensive speakers in the same setup as well.
That act reminded my of my Dynaudio monitors and even my way way larger (compared to Arros) "muscle car" OHM 5s which also suck up and thrive on whatever amount of power you throw at them.
