Having done much M22 listening recently, I would concur that the decision from M22 to M60 is mostly a personl one. The M22s do offer slighlty more detail than the M60s(from what I can remember of the M60s) and currently the M22 with my PB13 Ultra nears the same feeling I am getting out of my M80s+PB13, just not quite as full in the upper bass, which I believe, is why the M22+sub is sometimes said by myself and some others, to feel to be missing something.
