Most albums of great music are available in very decent digital versions, so it is not that essential to hunt down a vinyl version.

Bill Berry Allstars-For Duke (fantastic direct-to-disc recording)
David Peabody-Americana (obscure recording that was not reissued digitally that sounds amazing).
Duke Ellington-Blues in Orbit (6-eye Columbia original. Another recording not surpassed in reissue. Sony though well enough of the recording to make it among the first SACDs issued, but even that was not as good as the originsl0
