This is understandable. Jazz can be hit and miss. I have two masterings on CD of Art Pepper + Eleven, as well as Miles Davis Sketches of Spain and prefer the later mastering on each. The Count Basie record 88 Basie Street sounds really great, with very good dynamics (even explosive on some tracks) and full timbre, on the regular $10 CD, but just awful -- "gutted" indeed -- on the audiophile XRCD (what a waste of money that was).
A lot of the digital remasterings on Blue Note, done by Rudy van Gelder himself, sound excellent on CD. I have heard a comparison of Lee Morgan's The Cooker on LP and digital, and the latter compares very favorably. I have that recording on a Lee Morgan 5-CD set from Blue Note, on which all 5 albums sound really good. Those masterings are from the late 1990s/early 2000s I believe.
I find a lot of new jazz recordings very good as well on digital.
When I come to visit you one day, this will be a must hear then!
