Hey MiniRock,
I haven't personally heard ML's (Martin Logan's right?) to compare them with the M80's. You will love the M80's if you like detailed crystal clear sound in the highs and mids. They present a wide sound stage and you can point to the position where the instrument is being played. Its bass is tight and focused (not boomy or muddy). They have a forward sound that makes you feel the music (gets you moving). Some have said that they're on the bright side. This was my initial impression. After hearing them the 2nd time in a different set up similar to my room layout I really loved them. They were paired with a different receiver the 2nd time around. I'm not sure if the receiver made a difference or if it was just the layout but the really bright sound (makes your ears ring) was gone.
