Got it, I see where it's going!
(now don't tell anyone I said so, but ya gotta be quick in your listening-when I plunked down my M50s where my M3s had been, it took between 20 and 25 minutes for the obvious "harshness" to go completely away: Not quite "Right" at 20 min, to "Wow, that's better!" at 25)(or something like that)
