What is the best sounding vinyl?

theophile, For the recotd, I am referring to Reference Recordings, in capital letters, with reference to a specific studio that issued LPs under that brand name (RR) for a brief period of time, mostly jazz. I think the engineer was a Dr Johnson.  I own 3-4 of them.  They click every box you list, except of course their product does not span a wide variety of musical genres. 

Umbrella - Canadian label

Sheffield - mentioned above

Lyn Stanley - female vocalist - 45 rpm D2D - WOW

Analogue Productions has done a lot of 33 and 45 rpm reissues - excellent sound and music

Classical - Original Source from Deutche Gramophone and Pure Analogue from Decca

Interpreting the question a different way, i would say the JVC Super Vinyl used for the MFSL Original Master Recordings of the 1980s.  This was translucent, virgin vinyl that was extremely quiet, free of pops, and capable of being replayed immediately with no loss of sound quality.

Whatever vinyl Philips used in the 1970s was also very quiet, and so is the vinyl used in later MoFi recordings.  Is the Analogue Productions vinyl as quiet?

Any of the Reference Recordings albums, mostly they are jazz.

I know very little about jazz, and would like to get into it.

Can you (or anyone reading this) recommend one or two good Reference Recordings albums?  I will search for them on youtube, to hear if I like songs.  If I like them, then I will purchase the pressings.

I will not be using youtube for sound quality -- only to hear the performance to see if it gets my foot tapping.
