PSB makes some great speakers in your price range. Subs also. You can actually spend less. There are lots of great others too. I've always liked Jolida gear. I'd consider an amp from them if I was looking.

**PSB dealer disclaimer**

If you think you might get more serious about this down the road I agree with the others who said ditch the sub for now and get the best monitors/floorstanders you can afford (some good ones listed above) along with the best NAD integrated you can fit into your budget (used would be a good idea for the amp -- speakers are a little more risky used).

If this is really just for casual and/or background type listening you could save some $$$ and just buy something like this that should be more than fine...

Best of luck.

Dweller nailed it, try to stick closely to his recommendations - they will result in a *very* good sounding system...

do more research than just hangin' out here. you should listen to various systems if you have a possibility. a local high-end dealer may be a good start
