Well, I will chime in with my thoughts...
I go with that multichannel is fine for movies, but won't replace 2 channel for music, for ME, at this point. I have heard good multichannel (Primare Pre/Pro, Primare Amps, Primare electronics, JM Lab speakers, playing Dark Side of the Moon) and it is interesting. It is also different. It is also not the same experience for me, and I prefer stereo.
My wife prefers surround, so we ALL know that I will have it eventually - bought a Pro Logic pre/pro for her movie viewing this year, will eventually get a better surround decoder going, but I am in love with good stereo sound.
