I agree with Randy, get the surrounds first.

Before my Axioms arrived I already had the TV and Oppo so just for the hell of it I hooked up an old boom box to the analogue L/R surround outputs on the Oppo. Even with that cheap setup it was incomparably better than just the front speakers on the TV.

Get the QS4 and they will blow you away.
