Anyone out there experienced with M50v4 vs M3v4?

I am so much enjoying my M3v4 in my living room. I have to say in my living room, which is more live than my main A/V space, the M3v4 is far more enjoyable than the M5. The M5 is far more accurate, and more linear but I find myself listening to it in a very clinical sort of way. I don't have that problem with the M5 in my man-cave and prefer the M5 over the M3.

Given my newly-discovered love for the M3, I am wondering if replacing the M3 with the M50 will give me an even better emotional response. The M3 is currently paired up with two low end subs which really aren't doing much.

What do you all think?
