Classical labels I found to be consistently good:
1. Erato,,,great production and dead quiet vinyl,,,very smooth sound with great dynamics.
2. Deutsche Gramophon from the 60's (the label has a big arrangement of Tulips on top and surrounding the inner label..I find the performaances first rate and vinyl very quiet.
3. The Melodiya/Angel releases, are dead quiet vinyl,,,great sound.
4. The London label I find that most of the ones I have are very very quiet, with very nice performances...I just got my first blue back and its pretty good.
5. Phillips of any kind, especially if pressed in Holland,,,dead quiet vinyl and good dynamics.
6. Teldec Direct Metal Mastering (derived from telefunken (derived from Decca)),,,Spotless production.
7. RCA Living Stereo (I am not that willing to pay anymore)
8. Mercury Living Presence...(reissues are supposed to be excellent) (not willing to pay that much anymore either).
9. Hungaratron and Supraphon (Eastern European labels)
I am paying an average of 2 dollars per classical LP that basically have never been played (or it looks that way)
