I just spent the last hour comparing the X to the T1s just in terms of sound stage and imaging...I fully expected the T1s to remain the king of my headphone harem, but to my surprise the X has knocked them off the throne. I never felt the 2s were as confined as others did, but this is a whole other ballgame. These fazor drivers are the real deal...I'm having a hard time finding any fault with these phones at all, at least in terms of what I look for personally. Damn things are worth every penny.
EDIT: Okay, I just had an experience that blew my MIND. The Xs have very quickly become my favorite movie headphones. Tonight I decided to watch "Rush", the Ron Howard film that just hit bluray. If you guys want to hear something amazing, go to the 01:03:00 point of the film. You'll come to a scene where a bunch of racers are sitting in a room debating whether or not to cancel a race. While the main speaker is talking, other racers who are sitting at various points in the room debate and comment with each other about how they feel. I was hearing the main speaker front and center, the people to either side of him offering support, a guy at like 7:00 (on a horizontal plane) saying "exacto" under his breath, a few guys over at 4:00 who were further away but still perfectly audible, someone skidding their chair leg on the floor, and all this going on at various distances away from where my position would be. This is the sort of simple example that I look for when I evaluate gear...the imaging and sound stage that occurred during this scene was so damn impressive that I literally just started laughing.
Okay, I'm going to stop blowing sunshine up the Xs butt...I think it's obvious that I love these beauties. Oh, and by the way, the bass in this film was equally as incredible! haha
