My M80s never sounded anything near what I would consider bright. My room however is treated with sound absorbers on the right and left walls. I noticed right off the bat however that poorly recorded music (many discs from the 80's) sounds terrible on them, and properly recorded/mastered discs sound wonderful. As an example, I had many of Billy Joel's original CDs from the 80's, and they just did not sound good at all. I purchased a remastered version of "An Innocent Man", and it was a night and day difference (I went on to replace all of my Billy Joel CDs with the remastered versions, and the same outcome occurred).

The M80s (IMHO, and from my own experiences) are VERY revealing speakers. They really are the epitome of a garbage in garbage out set of speakers. You should take some time to experiment a bit, maybe share some of your settings with us, and maybe all of us could help you out.
