I don't care if this guy is a fanboy. All power to him. I'm glad to see these headphones are generating that much enthusiasm. In my view, a rising tide raises all boats. If Ultrasone has discovered the key to great sound, let us learn something from that fine company. I've never felt the HD800's mids were "thin" but I do agree with a couple of his comparisons, even if I've never had an audition with the Ed10. The PS1000 is a fantastic rocker but its mid-bass hump doesn't go with all music, especially classical. On the Schindler's list soundtrack, the first and second violins are prominent on my other Grados but on the PS1000, it's the cellos that stand out. If I were listening mostly to classical, I'd find that distracting. I also agree with this guy's criticism of the T1, that the soundstage is "too small" and "too dark," though that's a comparison I'd make if I were A/Bing them with the HD800, a headphone that has a huge soundstage and a more prominent high end than its predecessors.
Then again, a good part of the difference may be in the shells. These shells seem wider than the T1's but more enclosed than the HD800. Laying aside the obvious "pride of ownership" bias, there may be advantages to the way Ultrasone has approached its task.
