I haven't heard the M2s so I can't comment on those. However, if you want a more revealing speaker, go with the M22s. I consider the audiobytes to be a nice balance between the M3s and M22s. They are more revealing than the M3s and more warm than the M22s. The M22s will also give you a larger soundstage. The only way I can get a large soundstage with the audiobytes is by sitting "close" to the them. When I sit close to them, they also sonically disappear.
