Well, if my venerated IEM guru james444 says it's all about FR, then it is all about FR! My most sincere and deepest apologies for displaying my ignorance in such a blatant and disrespectful way!  
I'm certainly no expert, but over the years I've experimented with EQ quite a bit and I never noticed it having an impact on - for example - detail retrieval, resolution, speed and dynamics. I think your belief in FR is exaggerated. Sound reproduction is a lot more complex than perfect FR. FR will of course effect the overall signature of the sound (warmer, brighter, forward, etc.) but characteristics such as resolution, speed, dynamic responsiveness, etc.is the effect of...
Overall the difference between the DN-2000 and the DN-2000J is so much more than just a matter of frequency response, i.e. how much or little bass, mids, treble we get. Although FR graphs are interesting they don't say much about features such as detail retrieval, resolution, dynamics, sound stage and so on. I guess that's what you're saying when you write "Both are very different earphones sonically." but I felt it needed to be clarified to anyone choosing between the...
I agree that your conclusion most likely is the correct one, i.e. a combination of brain and possibly DD burn in. Sure, it doesn't matter to me personally why this change of treble perception has come about, but if it could be established that DD burn in is a critical performance factor it could be of significant importance to others. One difference between the DN-1000 and DN-2000 on the one hand and the DN-2000J on the other hand is the titanium treated DD. While I don't...
The tuning share similarities but the competence of the DN-2000J is hugely greater than that of the DN-2000. If you ask me the price difference is more than motivated. If AKG, Shure, JH Audio or some other well known IEM maker had released this phone and charged a $1000 for it or more it wouldn't have surprised me. Detail retrieval, resolution, dynamics, and sound stage are absolutely stellar on this phone and easily outperforms the DN-2000. The DN-2000 is no slouch...
I think I can safely conclude that you don't believe in BA burn in.  I really wonder why I perceive the treble so differently now compared to how I perceived it initially. I don't know how many hours I've put on it since I got it but it should be quite a bit. The most plausible explanation is of course brain burn in. On the other hand people in this thread have reported that they perceive the treble less sibilant/hot with the bass ring, and that's why I'm thinking burn in...
Jim Graff to the rescue! OUCH! 
If the DN-2000J has the kind of signature your looking for there's just no way it's going to disappoint you! What it does it does better - with a pretty wide margin - than any other phone I've heard.
Gosh, I had no idea (guess I should have )! No wonder we haven't seen much of you here! Sorry about that! Absolutely, don't misunderstand me! It's just that I find some Head-Fi:ers to be über credible and you're not one of them as you depend on your sponsors. It may or may not effect your statements and assessments at all, but it really doesn't matter as we'll never be able to tell for sure. It's just the way things are and a choice you've made, no problem, and as I'm...
When you see or hear about something that really excites you - like the Shure KSE1500 - it could lead to breathing too quickly and so causing too much oxygen to enter the blood which eventually may make you fall unconscious. English isn't my native language (Swedish is) and so I inaccurately thought the word "hype" was short for "hyperventilating". I've just learned that it's not but a word with its own meaning. Thanks!
