Need advice: best receiver/preprocessor/amp combination for $2500 or less

I need some advice. I am looking to purchase equipment for a new media room (movies and music both). I am having a hard time deciding between a single high end receiver (like the pioneer sc-68) and a good combination of separates.

Requirements: 7.1 capable. Must have 7.1 analog in. Solid power (5000 cubic foot room).

So, if you had $2500 to spend, what would you buy?

Thanks for the response. I am leaning towards the pioneer for simplicity. There is just so much out there in this price range in separates, I want to be sure I consider the options.

That is just the amp/pre/pro or receiver. I am trying to decide between a combination of separates (totaling no more than 2500) or a receiver in the same price range.
