Chris,
I currently have the Axiom VP150 with the QS8s and the M80Ti towers. This setup is amazing, it produces tons of very deep bass yet remains clean all the way to the top. I have not found any speakers that come close to the sound you get from this package without spending 3 times the money. Since speakers won't become outdated by new audio formats (ProLogic, DD, DTS, DTS-EX DD-EX) you may better served by buying the top of the line speakers now and saving your money for the high-end receiver later. If you haven't looked at the outlaw audio receiver yet you can find them on-line at www.outlawaudio.com, they have a very good receiver for only $499. It is not the ultimate piece, but will serve you well until you get the rest of the cash to do the major upgrade.

Just a thought,
Greg
