DTS-HD Master Audio is nothing new, of course, but the 7.1 demo sounded superb using standard home-theater gear, including a Sony PS3, Onkyo TX-HR3007 AVR, Definitive Technology Mythos 1 speakers, and Earthquake subwoofer. I learned a bit about the upcoming next-gen Neo, which will upmix to 11.1 channels to add height and width speakers to an existing surround system, much like Dolby Pro Logic IIz and Audyssey DSX.
