I'll second that. I've heard them at a local dealer a few times and was blown away at the sound coming out those slim towers... and they look even smaller in person. Very nice bass too.
I'll third that. I owned a pair for a few years back and they consistently impressed me, to a point where I'm considering buying another set. Within their limitations, they're one of my favorites and a great value. The Sttaf's are nice as well, a bit more relaxed in their presentation and easier to drive.
