Hi Snowmanvt,
The M50 is pleasant but doesn't have quite as much midrange and upper octave detail and clarity; as such it's unlikely to have quite as impressive a soundstage as the M60ti because the soundstage articulation is dependent on midrange linearity and accuracy.
However, when I did A/B comparisons of the two, I was focusing more on clarity and detail rather than soundstage per se, so perhaps an M50 owner might comment.
I listen to quite a lot of jazz and I love the detail and soundstage of the M22ti's, which is extremely close to that of the M60ti.
Regards,
