That's from the Tokyo Headphone show, right? That one is kinda huge and unique if I remember. If it's the same rig as from the event, it has some unique elements you won't find anywhere else for the most part. I like the idea of portable rigs where even if it's strecthing your pocket, it still technically can fit in it somehow.
but my "stack" is defeated by this one..
