Excellent information as above. I ,too, own JM catalog from debut to "Mingus". Original pressing CDs. No (HDCD) editions. I own 1 or 2 on DCC Gold Disc.
Per most of my CD/SACD collection, 90% are easily original CD pressings. Very few re-masters from 1994 to Present. The HDCD counterparts are The Grateful Dead and Neil Young (Crazy Horse) catalogs.
Happy Listening!
