Speaker recommendation. have $2,500

These have already been said but I will list them for you:

Vandersteen 2CE MKII
Magnepan 1.6
Gallo 3.1 Ref.

I've owned all three of these speakers and would agree with the great press they have gotten. Also check-out Jim Salk's offerings. I've heard his speakers at RMAF a number of times and have always been impressed. He has a strong following over on AudioCircle.

Check-out the new Magnepan 1.7. The retail is just under $2,000. Just saw these or I would have mentioned them before. http://www.enjoythemusic.com/ces_2010/preview/

If your room is larger you want to move a lot of air otherwise you may feel disapointed. For the money you want to spend I would definitely look at Revel F50a (I've owned and they are great...father now uses them in a 25 x 18 room and they are room filling). Budget might dictate a look at F32 or F30 models...The F32 would give more fidelity than the F50 but still not match the SPL's you need to push for Rock or heavy musical passages. It really depends on your style.

I own the Usher Be-718 previously mentioned and I would not recommend them in a large room. Also I would be skeptical of several of the other speakers in large rooms. Be careful! When in a large room fidelity of the speaker only matters so much if the speaker sounds lost in space.
