While DTS was industriously showing the 11.1-channel version of its Neo:X technology at South Hall, Onkyo was demoing the same technology at the Venetian, but in more low-key way, and with a mere 9.1 channels (5.1 plus back-surround and height, no width). We can't explain why, but it sounded better, even with the same demo material. The guy in the pic must have agreed as he slowly levitated into the air, somehow drawn to the height channels like a moth to flame, and spontaneously combusted.
