Serious Classical Labels


Curious to know what classical labels have consistently high sound quality. I've had really good success with the Hansler Classic, and Dabringhaus & Grimm (D&G) labels. Any other that stand out for their production qualities?

Pentatone
SFSO Media
BIS
Alpha
BSO Classics
Linn
Lipkind
Melba
Profil
Quintone
Channel Classics
Ondine
I'd add Fone and Fidelis to the list. Are you asking about digital, vinyl or both?
To add ...

I don't know if you like opera or not, but if you do there are some series put out by the majors that are very good ...

Opera House series by Deutsche Grammophone

Classics for Pleasure by EMI

Any opera with Rene Jacobs on Harmonia Mundi

Linn, Channel, and Pentatone are the top tier, followed by Bis, Ondine, and MD&G.
