I just purchased my sacd player and picked up Boston and Billy Joel's the Stranger at the same time. After listening to the Stranger, my mouth dropped. Billy's voice coming from the center speaker and all the other instruments and melodies coming from every different direction. Then I put in Boston and couldn't tell a difference from the cd version I already own. I think it's one of the best albums, but if you already own it on cd, don't bother upgrading - there's nothing special about the SACD version.
