If by superior you mean less in quantity, I don't want it. Nor can I afford something so exorbitantly priced.
I love the stock D7000 for what it is. If I wanted tighter bass, etc, I would get one of the million of other closed headphones that do that well, like a pair of Mad Dogs. Call it bass distortion or whatnot, but that's what made the D7000 stand out for me. The bass was different in an awesome way. Didn't ever wanna touch that, which is why I didn't mod mine.
Already have the K702 Anniversary as my warm, very balanced headphone. Don't need another. Looking for that D7000-type fun. Never should have sold it. Kicking myself every day.
By superior I mean the TH900's bass has far less harmonic distortion, so it sounds cleaner and will vary more from track to track. Both headphones actually have the same level of bass quantity more or less, and the TH900 is still a very bassy headphone. The TH900 is nothing like the Mad Dogs.
I think you'd have a better idea if you listened to the TH900. Cleaning up the distortion doesn't make the bass any less fun-sounding, it just improves the resolution and texture while keeping it out of the midrange through better delineation. To my ears there's no sonic advantage to the D7000. The only advantage is price. That's why it doesn't make much sense to me to wish for the TH600 to be another D7000. With all due respect, if you miss the D7000 so much why not buy a D7000 again? You can still find b-stock or get one used, and you wont pay as much as you would for a new TH600.
