Well, I can tell you already that the Magnepan 1.6s that I had were excellent speakers - but not in my room. The room was such that I couldn't be symmetrical from left to right AND I couldn't get the speakers far enough from the back wall.

Front-radiators, like the M80s do better in my room because I get more direct sound & less reflected.

I will post impressions once the M80s get broken in, though.

My opinion is worth exactly what you're paying for it!
