What instrument do you play?
I've never heard any of the speakers you listed. If I were you, I might consider starting with two speakers only, if that allows budget to get better speakers.
I've never heard them, but if I was buying today, I'd check out Salk speakers. They are more expensive than the ones you are looking at, but if you just get a pair, you might be able to swing it.
Some monopolar speakers that do pretty well with classical, IMO, are Ascend Acoustics and B&W 800 series ($$$$).
I listen to almost all of my music, by far mostly classical, on electrostats.
I also would recommend using a third identical speaker upright for your eventual center speaker, if mch music will play a great role. This will include blurays. Even though I only sometimes have a classical bluray in my separate HT, I still often ponder the idea of going with an acoustically transparent screen so that I could accommodate the three vertically arrayed speakers, on the same plane.

EDIT: Oh, haha, thread title says 2k, yeah, I'd try some Salk towers, very likely . . .
