Of course you'll want the "kit" that allows you to use a digital optical connection from the Xbox to the Outlaw, or you will get nothing more than stereo.
I've got a PS2, and Sony was nice enough to include the optical port on the back, without requiring any extra adaptors. I've got that running into my 1050 and the sound is simply awesome. No comparison.
