Phd: "In addition some of you are buying into more channels is better than less when time has proven that two channels for music is superior."
Time proves nothing nor do such assertions as yours. 2 channel has, since its beginning, been a compromise accepted only because of technical limitations. Now, if you want to assert that, for a given expenditure, you can get higher quality stereo componentry than if you spread that expenditure over 5+ channels, that's logic.
BTW, there's nothing to prevent one from playing stereo discs as two channel on ones multichannel system.
