Can we list the better labels? Chesky? Telarc?

As you mention Blue note, Chesky, and Telarc I assume you're taking about mostly Jazz. If so, Concord Jazz has consistenly good sound and artists as well and a lot of Verve (but not all by some margin).

If you're into classical some of the best labels for sound are Hyperion, Harmonia Mundi, Chandos, Delos, Dorian, Reference Recordings, and Telarc. EMI can be excellent as can London/Decca. For Eastern European music, Supraphon and anything with the Czech Phil. :-)

Sheffield Lab (sheffieldlab.com), Mobile Fidelity Sound Lab (www.mofi.com).

EMI for conistently remarkable programming.

Whoops, I meant ECM! Well, I got the "E" right!

I've found the Speakers Corner reissues to be consistently good.

Puntamayo discs usually sound excellent. This is world music and though you may not know what the music is about it sounds great! I never pass up a chance to buy one in the used bins or new! The label features artists from Latin America, North America, Africa, and Asia!
