zzyzx. Take what others post about speakers they did not choose with a grain of salt.
Find someplace to audition the M80 ht package for yourself, you will be blown away! I was for both music and movies. Though I have to admit that I didn't move around to check out the 150. Couldn't get my jaw off the floor long enough to!
FWIW. I just had a running conversation over at audioholics with a guy who started off posting that the M60 vinyl looked crappy, was sometimes harsh and had a weak center.
After some back and forth conversation, it turns out that he likes the M60 better for music than the system he bought, the speakers he got were real rosewood and he thought the center for the system he got was far superior to anything on the market.
So, in reality he thought that the M60s were a very good speaker and the vp150 was just fine, but had I not asked questions, it would have ended up as another one of those Axioms arn't good posts. (where the heck is that rollyeyes smily??)
