CAL! is easily better for a nice bass-rich sound without too much mid-cut, if you ask me. Aurvana Lives also do sub-bass better. And they're lots cheaper. M50 is so ridiculously V-shaped, that anyone lookin' for even the slightest hint of neutrality in FR should not be happy. And I just cannot understand why these are recommended for studio use (maybe it's the construction?).
And yes, I own both.
