On the used market I'd look for something like a Soliloquy 5.3 or a Silverline Panatella, both of which will put out enough bass to do justice to rock(and home theater) but also hi-fi enough to handle intricate jazz recordings(and neither requires a lot of power to sound great).
If you're looking new I've been hearing great things about Axiom speakers, and I think the floorstanding 80s will fit your budget(see Soundstage! review of the smaller 30s for reference). The bad news is you can't demo them before you buy them, but the good news is I think you can return them in 30 days if they don't work for you. With nothing to lose they're probably at least worth a shot if they work for you aesthetically. Best of luck.
