Headphones - Senn HD 800 or Grado RS1i.......


Anybody here had the chance to compare the two. I see that this site leans more towards Grado while the general outside population leans towards the 800s as far as "best" goes.
Anyway, I am looking for soundstage and good bass too and will probably opt for one of these two models if they have these qualities.

I'd like to also mention that even though I seemed to like what Grado PS1000 had to offer, the fact that I do a lot of listening while laying down on my bed didn't help, because these otherwise very good headphones, will NOT stay on your head the way they should and they will fall. Nobody mentioned this fact anywhere and in case I'm not the only one listening to cans while being in a horizontal position, I just wanted to be the potential buyers aware of this fact.
The T1's and the HD800's both have aspects i love.

T1's = Bass impact
HD800's = Soundstage
