Full Range: I'd have to say the mbl 101. Also a pair of Duntechs that I heard in a mastering room.
Honorable mention would be anything from Magnepan, Vandersteen, and Ohm.
Monitor: PMC AML2, Focal Solo6 Be, Dynaudio Air 15
Favorite sub/sat (I'm making up my own category): Orbs
Speaking of audio shows, I've also heard some disappointing rigs. Definitely the rooms aren't the best. But I think most of the gear at those shows just wouldn't sound good in any room...
