Based off the frequency graph, I was also considering getting me some Fostex TH900s, but they are a bit pricy and the hinges seem fragile.
Also somewhat considering the Sony MDR-1R, but they aren't released yet.
I'd be "upgrading" from my Beyer DT250-250 which are great, and I have my ATH-W1000X which have bass emphasis, occasionally more detailed than the DT250, but subbass is quickly rolled off - noticeable in a song - Age of Dub http://www.youtube.com/watch?v=fQlpKCmTMoc @ 2:45. Also, I am assuming that the two lower bass sounds still are there in the song after compression, etc. No proof that they are there because I have not heard them.
Not sure exactly what I'm looking for. I'm just kind of floating around after recently getting my ATH-W1000x which I hoped would be my last headphone purchase ever.
I generally listen to j-pop.
My current setup is: Laptop-> Dacport with 1-ohm output impedance mod (not the most detailed according to what I have read, but nice and smooth sounding)-> Headphones. *cough*
Anyway, sorry for the rambling and thanks for any questions/comments/suggestions.
