can you guys recommend me a 5.1 speaker and av receiver setup for RM2k?

new to the home theater thing. i did some research and found many entry level av receivers like yamaha rx 375 and denon's 1513. speaker commended by some websites are Boston acoustics xs5.1 and yamaha's p20/p40/p380 range. would you guys recommend something different/better within that price range?
