What is the best sounding vinyl?

I can only comment on record labels that are current and still producing records like  Intervention Records and Speakers Corner Records out of Germany. 

Also, the Dave Rawlings and Gillian Welch owned Acony Records/Woodland Studios. 

And of course Analog Productions. 

Just about any recording from the Japanese label East Wind will sound very good; those that are direct to disc are particularly good but one would have to buy originals to reap the benefit of direct to disc.  For example, search for the Great Jazz Trios “Direct From L.A.” 

For classical, consistently the best sounding label was Lyrita.  However, their catalogue was limited to U.K. composers.  Also good were 1950-60’s RCA, Mercury Records, and Decca/London classical records.

I forgot about Windham Hill Records as sonically many of them are first rate (just depends upon your personal taste - I like a handful of them).

Octave Records from PSAudio. Uniformly great sound and unusually (for an audiophile label) a wide variety of great music. Second place to Chesky records. Mostly classical and jazz but both typically interesting. 

I thought this was about recordings with the most near perfect sound quality. Not about recordings with the greatest performances or best musicians. For example, Sheffield often recorded mediocre musicians. “Blues and abstract truth” is a very good recording but not technically among the best recordings. Music on it is sublime if you like jazz, as I do.
