I am thinking of upgrading from the M50'S to the M60's. I want to know since I dont plan on getting a sub until later this year, will I see a noticable difference in the bass response between the two or should I not even bother. My main objective is the bass but not an over muddled sound, nice tight but strong feel.

Take a look for recent posts on a comparison b/w the two.
