Obviously, if one sticks to audiophile labels, the recordings will tend to be of superior quality,
But there are also plenty of labels that are not specifically considered audiophile labels that have very good sound quality.
The jazz label, ECM is one of those. A very high percentage of their releases from the 70's up through to the present are excellent. And the music is always interesting, Even though it is mostly jazz, it has a certain chamber music sort of quality to it. Maybe that is because a high percentage of their roster is made up of European and Scandinavian musicians, that have a background in western classical music.
I've heard some minor complaints that they tend to accentuate percussion a bit, but it is recorded so cleanly, I have no problems with it.
So many I could list:
Azimuth with Ralph Towner - Départ
Ralph Towner - Solo Concert
Michael Formenak - Small Places
Craig Taborn - Daylight Ghosts
Keith Jarrett - Koln Concerts
Eberhard Weber - Colours of Chloe
Chris Potter - The Dreamer is the Dream
So many more.
