uncompressed RVG

My impression - which may differ from other folk's - is that they more recent the remaster the better the sound quality. It seems that on some of the earlier ones they weren't paying much attention. I have a couple that are very good. Tina Brooks' True Blue; Art Taylor's AT's Delight; Donald Byrd's Byrd in the Hand and Catwalk all come to mind.

Are we talking about digital, vinyl or both?

i'm talking about the cd's
