Nice set ups at the tables, not just the vendors...I brought a bunch of headphones with me, but I felt intimidated by the 1st tier headphones and sources everyone had there, looked much more on point than my poor source material (Fiio X3, 2 iPod Touches, ALO National) and mid level headphones. This is actually the way I listen, with portable rig, if I want to use big set up, usually use speakers, but walking around, laying in bed, other times, always on the DAPs.
Loved the Audeze comparisons, agree with above, all nice sounding, house sound, could use slightly more on top imo, but really enjoyable.
Loved Alpha Dogs
Lots of other nice set ups/cans/sources/amplficartion
