Don't forget about SACD and DVD-A in multi-channel, hi-rez. DVD-A in multi channel is actually pretty cool. One song that was particularily memorable was America's "Ventura Highway" (for all you old schooler's out there) that really utilized the surround aspects quite well. The Eagles "Hell Freezes Over" live concert is also very cool in surround w/ the audience applauding behind you. While I still do all of my critical listening in two channel and w/ the sub turned off, I could easily see jumping into the sacd/dvd-a fray if for nothing else because it makes some of the old classics new and fun again. Isn't that what our love for music is all about?
