Personally been researching receivers and speakers for about two months now. For receiver ended up buying a Marantz SR-5001, which compares to Denon's 2307Ci, but it was basically a coin toss between Marantz and Denon with Marantz winning for being slightly better handling the type of music I hear most. For speakers still deciding.
Denon 2807 is a good choice, don't know what else Magnolia BB has, as they will not finish construction and open in PR until Feb. 2008, Circuit City opens their first store in one or two weeks.
Regarding the projector, don't know what to tell you, but you will find lots of companies selling in the internet at a better price than BB, and offer 0%/12 mths. financing.
Even though I have not decided on speakers, have read a lot regarding both of your choices. It looks like the Mirage offer a better sound image for Home Theater use.
Good luck, as this are the crucial life changing decisions that will hunt you for the rest of your life...But, like everyone say, trust your ears.
