If you want a sonic spectacular, try one of the last three of the Moody Blues’ core seven on SACD. Huge soundstages, a constantly changing soundscape with lots of effects, great guitar riffs, wide dynamic range. The 1997 remasters may be as good, but I haven’t heard them.
I don’t want to start a fight, but these albums were all made at least a year before Pink Floyd’s DSOTM and IMHO, they leave that classic in the dust as far as sound quality and use of studio technology go. You may disagree, of course.
Also McCartney’s recent reissues in the Paul McCartney Archive Collection qualify as sonic spectaculars. They have great sound, a complex, always changing soundscape with lots of effects and musical accents. Just pick your favorite.
In a different genre, If you like music rooted in bluegrass but with many other influences, check out Laurie Lewis’ "Blossoms." It opens with a beautiful 3 part acapella tune that’s pretty impressive. If you like bluegrass at all you should check out Laurie’s "Earth and Sky" compilation. Beautiful music.
