"If you love your XM Satellite Radio now, you may fall deeper with the news of XM HD Surround stations and hi-def programming. Coming in March of 2006, with just a little more hardware from hardware companies like Denon, Onkyo, Pioneer Electronics (USA) Inc., and Yamaha (which I’d bet we’ll see at January’s CES), you’ll be able to get 5.1 audio from the satellite radio company. Officially called XM HD Surround, it provides content with six discrete channels of digital full fidelity audio powered by Neural Audio technology. The first broadcasts will include the free-form music channel Fine Tuning (XM Channel 76) and the classical pops music channel XM Pops (XM Channel 113) as well as a variety of special shows and live music performances at the XM studios." I am assuming this is more for the home user market rather than the auto market. After all, how many people have a 5.1 surround sound setup in their car?
