Audiophile Record Labels

Wow, thanks for all the responses everyone!
I'll throw another label into the mix as well. I purchased a Rhino Records version of Al Stewart's "Year of the Cat" on the recommendation of a friend (as it's one of my top 20 rock albums) and it completely blew away my Arista version.

Thanks again.

Yes, Rhino is generally very good.

I've also been pleasantly surprised with overall quality of various classical vinyl titles I have encountered on the Musical Heritage Society label.

Alia Vox for early music (Jordi Savall's label), and a big second thumbs up for ECM.

fone does great classical recordings as well
