Best Sounding LPs

Thanks for that 4yanx, they're on the list. Female artists, I love the genre! One female singer whose single LP is extremely interesting and fun in a pop-jazzy kind of way, but which either sounds good (really just acceptable) or muddy depending on your system's balance is Rosie Vela, a stunning beauty from the '80s: worth the photo on the cover alone! Anyone have her? Anyone find a system in which she sounds good? And for audiophile-type sound quality (but ordinary pressings) with extremely interesting music, let's not forget Laurie Anderson, "Strange Angels" and "Mister Heartbreak", featuring the voice of William Burroughs pretending not to be Thomas Pynchon! Excellent music, excellent recording, and Burroughs tweaking the nose of those who believe that he and Pynchon are one and the same man (personally, I think so). This is fun! Any more off-beat suggestions? Are you taking notes, Bsal?

The best sounding LPs are the ones that bring you great joy when you listen to them...regardless of surface noise ;)

Dire Straits "Brothers in Arms" works for me.

The best sounding jazz-pop lp, which I use as a reference, is Donald Fagen's "The Nightfly." I have the Quiex-2 version. Terrific.

Jazz - Coltrane's Blue Train on 45rpm.
