I have been buying quite a few sacd's lately and just absoultely love the way my 5.1 ascend/hsu setup sounds using the new technology. My favorite disks so far are: Land of the Giants/McCoy Tyner (Telarc SACD-63576) and Stan Getz Quartet/ Pure Getz (Concord Jazz SACD-1000-6).
The Tyner sacd features not only the great pianist but the great Bobby Hutcherson on vibes. Giants indeed.
Even though the Getz sacd is a re-mastered version of his quartets' 1982 analog recording (towards the end of his career and one of my favorite Getz records) Concord Jazz has done an excellent job and to my ears the sound quality is almost as good as the Tyner disk, which was recorded in pure DSD.
Anyone else have a fave jazz release?
