Sorry to repeat if somebody else mentioned this, but did you try recalibrating your 950 with a SPL meter? If not, go down to your local Radio Shack and pick up their analog SPL meter. It should cost you less than $40. Then try recalibrating with that. As SH and all the posts above point out, if you're still able to sit in the room, after recalibrating, when listening at those high levels, something is definitely amiss.
