With your budget, I say do it right the first time, and I speak from some experience.
Go with three identical speakers all on the same plane, vertically arrayed.
You will have the ideal mch setup in case you ever get to concert/music blurays, sacds, dvda, etc.
That may require an acoustically transparent screen. Look at Seymour retractables, if you like looking at your speakers for music only purposes.
While any and all of us can throw out recommendations, I vote that you go out and listen to as much as feasibly possible. BW and Focal are very reputed, and that's a good start, but I would be happier if you listened to much more. I aimed for 50 speakers, and got about half way there before I got sick of myself.
