Hi there! Not too long ago, I posted my own personal comparison of the classic CBM-170's and the M22's here. I could have done a more thorough comparison if I wanted to, but just trying to gather up those thoughts was enough to drive me bonkers! Anyway, I hope it helps! I really wish I could get a chance to listen to the 340's as well.
