Soundstage wise the orthodynamic are at a disadvantage, one of the downside of the driver design itself. I found them still better than the LCD2 in that area. The worst thing about the LCD2 is the way they sounds totally boxed in with lack of air, soundstage is small but with decent accuracy, slightly congested though. Other than soundstage and the lack of "air", overall performance of the LCD2 is impressive, I wonder if you are going to review them. If you don't mind the lack of air and slightly bassy signature, you are in for a treat. Unfortunately I am not one of them, Audio Technicas limiteds and STAX for me.
I found the EF1 with HEs and LCD is less than optimal, a high power SS amp like a B22 is far more impressive sounding than running off the EF1. However, I found the EF1 and D7000 pair pretty nice.
