Did you try playing them loud? Sometimes I noticed the M22's brake up a little bit when they are loud. Did the Ninja's change that? I was reading they said it helped.
Your welcome and yes I did take them up to eleven a couple of times(Pink Floyd - DSOTM, how can you not?) and they were just as revealing with out any noticeable breakup, just crystal clear sound. They are a very impressive change up, but definitely not for everyone.
