Are you bothered by number of components? You could probably do everything you want through a good hi-end dock (B&W's Zeppelin Air for example). Only issue would be with integrated speakers, stereo seperation isn't gonna be the greatest.
You could go the micro/mini-system route, but this will most likely have CD and FM/DAB too, which may or may not be of any benefit to you. One advantage is many of the established micro systems allow purchase of the speakers separately, so if you wanted floorstanders you can mix 'n' match.
Going for separates is gonna push your budget unless you're happy to look at second hand gear. This route will ultimately bring greater quality though, and will allow you to upgrade individual components over time instead of just junking the lot when you want to 'move forward'.
