Funny, I heard Dark Side of the Moon ("Money") at the C.E.S. I think that it was the Wilson room???? Anyway, it was REAL high quality multi-channel SACD room, and I found the presentation sort of disconcerting. Maybe I'm just an old fart, but DSOTM was permanently etched into my halcyon consciousness as a 2 channel mix in the '70's. As has been commented upon in this thread, finances and spatial considerations make SACD multichannel much less prevalent in the home than SACD stereo, one would think.
