Looking for some info on speakers

I'm a 'newby' to the high end audio scene, but love music (Jazz is what I listen to primarily) and currently am running on NAD components - 317 intergrated amp, and the C 540 cd player. My local dealer recommended JMLabs Cobalt 810 as a good speaker fit. These sounded excellent in the store, but I don't know much about them, and wonder if anyone can reccomend these or another brand to go with. Any suggestions? (looking to stay in the $700-1200 price range)
