Hey Hawk,

I had this issue with the m22s also. And I even stooped to trying the resistors. All the harshness I was experiencing from listening to them for extended periods, disappeared when I installed the resistors, but so did the soundstage. So I removed them. I vote for giving the resistors a chance with your 60s since it won't cost anything. And maybe, just maybe they will produce the sound you've been looking for.
