I am an awful photographer, and I hopped rooms very selectively. But the other highlights were the Von Schweikert room, and LeHave audio.
Today I want to revisit Spatial (couldn't get an adequate impression based on the music being played and didn't want to interrupt a serious audition). And then I'll more systematically work through the rooms.
Oh, and on the headphones side. The new Mr Speakers electrostat headphones were great, as were the new IEMs from Alo Audio.
