In addition to what chess says, I would try moving the M22's forward towards the couch, even only a few inches. Also, the "collapse" of the soundstage when listening outside the sweetspot is somewhat normal in the 2-channel stereo. Do you hear the same promlems when you listen to music using the matrix surround mode such as DPL II Music, engaging the center channel? You might well like it better than the streight "pure" stereo -- in fact I do.
