Higher resolution Jazz

Apologies to OP for not catching his older music part of the question. Never mind!

The first RCA Living Stereo was 1954 if memory serves. Actually, '54 through 1960 was what we refer to as the Golden Age of classical music.

I spent many years becoming an "Audiophile", until one day I realized I was trying to hear the differences in wire. If you're still trying to hear the differences in wire, what difference does the music make?

I hope you're back Elizabeth, I believe you're post summed it all up.

Enjoy the music.

B Limo-

as my reference disc I use;
Jamie Cullum- Twentysomething CD/SACD (2004) Verve

this is a killer release totally recorded in the analog domain for compact disc. The result is simply outstanding!
The best and last track on the disc is a "live" offering from the BBC studio- 1 take, minimal microphone usage. Test drive it for yourself. Happy Listening!

Xrcds or anything utilizing K2 mastering always sound good to me...Big band era has some seminal releases but often subpar sonics...like others have stated.
..late 1950s on up is usually hi quality recording...note-im a jazz enthusiast and not a scholar... But sold advice from jazzheads so far...I also have some Concord releases... Impeccable sound
