What current production Audio Technica headphones are closest in sonic signature to the leatherhead? Basically: a nice extended frequency response in both bass and high frequencies, no weird humps or lumps (at least, not extremely so); closed; smooth in the midrange, really smoov.
ATH-W5000?
I missed the boat on the leatherhead, and am regretting it. Yes, I could buy used, but in the meantime...
