He said he ranked them based on how much time he spends with them, so obviously he's a basshead. The DX1000 is supposed to have the most intense bass of any headphone.
Comparatively, the TH600's bass is pretty weak, Grados are bassless, ATs aren't much less so, the Sig DJ is a bass monster... etc.
Hahaha, the DX1000 bass is not close to being the most intense of any phone, the JVC SZ2000 would be the one you are thinking of. The DX1000 has well extended bass, but it is not even more in quantity than the TH600, while also having rather emphasized midrange. The treble isn't too rolled either. The signature DJ bass is strong, but not much stronger than a TH600 either. I consider the TH600 bass strong, Sennheisers, Grades etc are not bass less either in my view. I wouldn't define myself as a basshead, I do enjoy less bassy cans like the MS Pro HD800 and T1 and as an overall can if i owned one I'd probably find myself listening to a HD800 almost the most. I put more emphasis on overall sq than anything.
Heres the only dx1000 measurement there seems to be on the web
The DX1000 is just a very good closed can that I feel suits me the most, especially is euphoric midrange and huge sound staging.
Putting the DX1000 over other high end cans is not unusual, there is a lcd2 vs Dx1000 thread with a poll, the DX1000 out voted them. Of course the DX1000 would be one of the most unknown closed high end cans, kind of like how the FAD PH IV has been flying under the radar. I'm not sure some people who might end up popping up in this thread would know what the DX1000 is without a Google search.
