Maybe it is only me, but I do have a little bit issues about this review.
When your reference is AD2000 and Grado, words like "warm", "air" and "forward mid" means very little to me since none of these phones are "neutral" in the first place.
For example, I find everything I have heard (apart from beyer's custom pro one) has a "forward mid" compare to Grado. (Just personal opinion) .
As for sound stage, many phones have "wider" or "Air" sounds because some tuning with added "WOW" effect. That does not mean they are accurate and detailed. I still find HD800 having less "space" than the T1, manage to provide a better sound stage.
In addition, I really do not think that the only thing a planar can do is to provide more sub bass to a hip-hop song. I do think you need to elaborate more about the bass. Detail level, control as well as how deep does it go. (maybe throw more sound choices? I think all songs have bass, you should review it against different Genre)
(You are reviewing a $1000+ headphone, not beats........ So, I was hoping more comparison from the same pool: LCD2, HE6, W5000,AD7000,etc)
apart from all above, I think it is a grate reviews. Very nice photos.
If you want to send me your LCD2, HE6 and etc to compare then I'll gladly compare them. I don't have those headphones so my review is coming from a mid-fi enthusiast and experienced headphone reviewer. Take that as you will.
