Hey Ravi,
No, I've not compared M80's to 60's, although Alan (over the phone) did explain that M60's a comprable to M22's + sub, I was considerably more impressed with the M80's in that comparison, I've also noted previous posts in regard to the lack of depth or "punch" associated with M60's.
By the way I've found many discussions on this board, technical aswell as subjective, to be informative and helpfull in my recent decisions in buying speakers here. Thanks to all that have contributed and best regards.
