With your budget and your amp (which I also own), I think you have a lot of great options.
Jylee mentioned one I have heard at length: The Focal 1007be. It sounds excellent with the XA30.5 -- transparent, detailed, expressive. The 1007be has a touch of treble emphasis, though, so your source shouldn't be bright or etched, or you will hear it.
You'll get more helpful suggestions if you tell us about your preferences, or previous speakers you owned, what you liked about them, what you didn't.
