You need to go somewhere and listen to a variety of speakers and decide which ones you like, because speaker preferences are quite personal in nature. My suggestion is to take a look at speaker recommendations at sound and vision dot com, and then track down dealers for the speakers in your budget range. I personally like speakers from B&W, KEF, PSB, Paradigm, Golden Ear, etc, but there are lots of other really good speakers out there. No one will be able to tell you exactly which speaker set up you should buy, This is a very personal decision that only you can make after listening to them in a good acoustic environment.
Good luck in your search and let us know what you eventually buy.
