Higher resolution Jazz


I'm starting to get more into Jazz music since watching some documentaries on Jazz on Netflix but it seems like all of the older Jazz recordings are of poor quality; can you guys recommend some artists and albums where the recording is of a higher quality?

Thanks!!

Schubert, I sometimes enjoy the Emerson's recordings (haven't heard them live since the early 80's) but I agree that they get an inordinate amount of praise if not a free pass. Their Art of the Fugue CD sounds like a keyboard synthesizer to me. As far as younger quartets go, you might enjoy the Miro Quartet. With the demise of the Guarneri they are becoming my go-to group.
Thanks Tosta, I haven't heard the Miro but will check them out, and yes, the Guarneri had soul in spades !
My faves were the Lindsay and above all the long-gone Hungarian whose Beethoven and Bartok cycles are on Vox are to die for.
The Hungarian Schubert "Death and the Maiden " on Vox is perhaps my most treasured LP.
Here's some older jazz recordings that have fantastic sound ... if your system is up to the challenge.
