More than two channels didn't make Quad a success in the 70's and it has not taken DVD-A and SA-CD too far. Face it, the notion that M/C is the little engine that could is/was wishful thinking. The notion that you need more than one or two speakers to enjoy music is not gonna spread like wildfire any time soon. Selling surround music to hardcore audio-vidiots is possible but for everybody else it's like trying to sell them moldy cheese at inflated prices. I never believed the myth that 5.1 was the "killer application" of DVD-A and SACD. I thought that was bull and wishful thinking from the start. Someday the myth may become real but I think that's a decade down the road... Wish what you want but for now 5.1 is no killer ap.
