Demonstrating their wireless 7.2 channel speaker / amplification system, Neosonik's system uses a proprietary 5 GHz wireless system to transmit signals digitally to each speaker. A central controller will accept an HDMI input and then transmit audio digitally to each speaker. Each speaker in turn has digital amplification for each driver. I asked about the video portion of the HDMI signal that had been routed to the controller. They've a device that transmits that signal digitally as well to a small receiver connected to your display.
The price of approximately $15,000 makes the Neosonik anything but an impulse buy. Imaging seemed pretty good on the Cars disc, though the picture glitched up once. But due to the fact that their Blu-ray player takes five minutes to switch discs, they were unwilling to put something a bit more musical on. We'll be sure to check on them next year and see what's playing.
