I have never ever once heard a headphone with a *great* sound stage. Even the best I heard had just an adequate sound-stage placed inside your head - and yes, that includes binaural recordings (why do they bother?).
Both my Beyerdynamic 1990 Pro and Shure 1540s sound super resolving (and I love them), but I only get a realistic wider sound stage in front of me with my 2:1 setup.
