The choices I am posting, are NOT the most valuable, nor are they my absolute favorite music. I am listing these because of a variety of factors, sound quality of the record vs. digital alternatives, lack of digital alternatives, and sentimental value.
1. Brubeck-"Take Five" The original 6-eye Columbia sounds better than any subsequent reissue.
2. Ellington-"Blues in Orbit" The original 6-eye Columbia sounds better than any subsequent vinyl reissue and the SACD that I own (at least on the SCD-1 player I use to own).
3. Michael Hurley-"Have Moicy" Great music and pretty good sound. I bought this record when it first came out and I still love it.
4. The Great Jazz Trio-"Direct from LA" Fantastic sound from this direct to disc recording; subsequent reissues not quite as good.
5. Ramirez-"Missa Criolla" I have the original Los Fronterizos recording of this recording (Argentine Philips); I found it in the $1 bin at a used record shop. Amazing sound and, to me, a better arrangement of the music than subsequent recordings of this first approved mass (post Vatican II) sung in the vernacular.
