I caught Richie's set in Detroit last weekend, and it sounded a lot like the track that's posted. The sound system was Funktion1 and it was set up in 4 corners, but I think it was just a stereo rig. I've seen Richie do four corner panning of sfx in a room, and with enough sound in a small space you don't necessarily have to be in the sweet spot, although it is better there!
Regarding the music, it seemed to be more for the head than the body, as there were a lot of breakdowns and (in my opinion) too much time between basslines, but still an impressive set, impressive sounds, and his mastery of current technologies is always impressive to watch. Looking forward to the new album.
