I'm using a 2 watt Decware SE84UFO amp with high efficiency (96bd) speakers and an Omega deep8 sub in a 1,000sq ft apartment and love it. Volume on the amp never goes past noon. Plenty of volume, density, imaging, and overall great listening. I think the key to is not get an amp that over powers the room.
Decware amps and Omega speakers are a great place to start.
