I must say though, these cans are absolutely beautiful with classical music. Definitely on par with or better than my 701s.
UPDATE- I'm starting to like these more than the 701s... I burned them in for a few hours with pink noise, and they have maybe 12 hours on them now. The bass has already started to pick up. There was a noticeable change from just about 3 hours of pink noise, but unfortunately, they aren't as open sounding as the 701s, which isn't surprising in the least since they're closed.
I was thinking, would something like a ZO2 amp boost the bass on the 701s to the level of the K550s?
