Hmm, I'm still waiting on what the HE400i will bring to the table. I mean LCD2 had endgame sound, but dat weight and lack of comfort was a dealbreaker.
I just really love the planar sound, which is just different from all dynamics I have heard.
As much as I'd love the TH900, it still loses bullet points, mainly in it being closed and having fake leather pads.
I think the HE400i/PM-2 (home) + KSC (work) + 15G/MOE (relaxing at home) would be it, AFAIK.
