I'm looking for a new pair of phones. I owned a pair of M50's and after buying both the DT770's and SRH840's I still found myself holding the M50's as a personal favorites. Well, the M50's went to can-heaven (god bless them) and I want something to upgrade with a similar sound signature, but with a less bass-heavy bottom and more clear treble and highs. I tried the D7000's and loved them, but unfortunately they aren't in my price range (sub $400). Any recommendations for a similar freq response of the D7000's, preferably closed back, circumaural, and under 400?
