I purchased NX-Oticas from GR Research. They come in a kit and you have to assemble them. But, the sound quality is Outstanding! I also purchased Double Trouble subs from Danny at GR. The entire ensemble was under $3k. Imaging, bass, clarity and just over-all sound quality is great! I power the Otica's with my McIntosh MA 12000 and the subs use their own plate amps.
My room is roughly 15x 30 feet. The speakers are all open baffle. The music fills the room and can be loud or soft as you desire and because it is an open baffle system, it doesn't pressurize the room like conventional systems. This means you feel the bass but it somehow doesn't carry through the walls like normal subwoofers.
I actually ran into a guy at the stereo store and to my surprise, he had the same speakers as I did. We both compared ours to some $50 k Sonus Fabers and both came to the conclusion that ours are equal to or a touch better. $$$ was of little concern to the other gentleman. I got to listen to his in his 2.5 million dollar house.
So! Check out GR Research for speakers. Best bang for the buck out there!
