Having heard some of the master tapes on R2R, I can vouch for the best quality transfers from the master tapes on the Italian label - Audio Nautes.
The care taken on the transfers of the recording into the lacquer, and then onto vinyl is by far the most exquisite I have seen. The packaging and inserts beyond doubt are the best and no one comes close to them.
warning- they are dear, but it is the closest you get to the master.
I came across this label when visiting the Munich Hifi show a couple of years back.
i was fortunate to meet Fabio the owner, who was demonstrating the CD, the Glass CD, the LP and then the master tape in a room. By far the best experience I have ever had on software.
They are working on the Belafonte at Carnegie 45rpm one sided and one step pressing. It will be the ultimate if you do not have a great reel to reel set up.
Do Google them and check them out. They mainly cover the classics from the classical and jazz genre.
