OK so I have the m60s...so not the same speakers but not too far off. But my immediate comment is that people say the m80s are very "fussy" in placement. You should spend a bit of time adjusting them in small increments and then listening at the sweet spot. You may find that just from a bit of adjusting they sound a lot better. Also, try to test them with a number of different cds. My m60s sound a bit bright on a few disks I have, but I've found that in those cases it is often the disks (sometimes even just a particular song, on a soudtrack for instance). I am impressed with the bass that my m60s put out when they're fed enough power, (although the are no match for a good sub and should supplemented with one) but the midrange blows me away on a good number of my cds.
