I think the mode you are using on your processor is going to have a lot to do with this equation. In 5-channel stereo your current system would have the highest dynamic capability. In one of the usual surround modes or 2-channel then the M80 system would have more. All in all it is going to be a close one, you are going to a have a great dynamic range capability either way.
