Hmmm.. I was instantly happy with my m80's.

What speakers did you primarily listen to before you purchased the m80's?

What type of music do you typically listen to?

Are you using any EQ or room correction software such as Audyssey?

How far are your speakers apart from each other, how far are they from the back wall, and how far are you from them?

How do you have them wired up?
