If you are interested in Hi REz audio. It would be a great idea to hook up a pair of M22's as the rear speakers for that setup. All you would have to do is hook up the rear speaker outputs from the DVD player into the surround back inputs on the Reciever instead of the side surround inputs. The speakers would still be hooked up into the reciever as back surround channels in DTS and Dolby soundtracks. So I would definitely recommend either M2's or M22's for the back surround channels.
