Obviously Genelec's aren't probably the obvious choice for your decor, but you could always mount them on wooden plinths to tone them down.
I have mine in a fairly open plan room which the main part is 15ft x 25ft and 17ft high.
I've had to turn the bass down which suits me more (I like the flexibility to tune the speakers to the room), these fill the hole house, so I don't think you'd struggle with your room.
Sorry, but I can't give any sort of reccomendations with classical, but acoustic, concerts, electronic and general pop, they just lift it up a step from anything I've heard previously.
Think DDC mentioned 8250's. Dunno how much the 8260's are over there, but they're a 3 way unit, I'd love to hear them.
