Another shout out for Charney Audio! I have a pair of Maestro's with the Omega RS7 driver ($5,400) in my 11x15x8 room. Sensitivity is 100db so low powered SET amps are the way to go. I have ANK Interstage 8w300b amps and can't get enough of what this combo can do. In the room performers, drawing you into a deep, wide, and engaging soundscape. If your within a couple hour drive to Central NJ make an appointment with Brian. Very well worth the experience!
