Get the big Maggies and a "bigger" amplifier to drive them. With your budget, you can get the new Maggie 20.7's; if you want to spend less, you can get the 20.1's. The Maggies will love all of that room to "breathe". I know this sounds self-serving, but I would consider selling my 20.1's so I can get the new 20.7's. You won't regret getting the big Maggies, just as long as you give them enough power.
