I was considering EAR 912 very strongly too. The other competitor was Audio Note M5/M6. I had auditioned the M6 and loved it. But EAR 912 had a very good built in phonostage so it seemed to be a more attractive option. I finally got to audition it and guess what, it is no more on my wishlist. To my ears, as you mentioned, it lacks air. It lacked delicacy and nuances, a very matter of the fact presentation. Dynamics were big but not effortless. When I played a live recording, the audience applause and did not have the organic quality to it. I would call this preamp dry sounding.
Check out ARC Ref3 or Audio Note M5 or Air Tight ATC-2 in that price range for more organic presentation.
