You have a fairly large room. Depending on your taste for bass, you may need to think larger when it comes to speakers. Try a pair of Snell D's. You can find them for 600-700, a ridiculous value. The McCormack amps would be a nice choice.
If you're not a bass nut, the Maggies or the GMAs are very nice. But they won't energize your room at high levels.
