Removal of acoustic popcorn ceiling?

We are remodeling our house and currently have an acoustic (popcorn) textured ceiling. My wife would like to remove the popcorn texture but I am afraid it is going to hurt the sound. We have a very open floor plan and the room where our system is only has three walls (side wall is brick) with the fourth wall being our dining room and kitchen. I have a fairly modest system (compared to many of you) but I am fairly content with the sound I currently enjoy and do not wish to compromise the sound for this aesthetic change. My wife is very accommodating and has agreed that the popcorn stays if its removal will have a negative impact on the sound. Your input is greatly appreciated.

The system (if it matters):
Anthem AVM-2
Anthem MCA 5
B&W N805
B&W HTM2
Ceiling mounted rears
Klipsch sub (to be replaced by REL Storm)
