Quality required to hear vinyl

Anyway you could get some of these components together and see what you hear for yourself? That is truly going to be the test.

Virtually any vinyl system will demonstrate to some extent the difference between analog and digital. The sound difference is not subtle.
As for Bliss well-
I seriously doubt it. That takes a couple of years of frustration first. It will tell you if vinyl is your "Cup O Tea"however. If it is then you will start looking at phono stages and cartridges, Vta, loading etc. After that you wonder about tone arms, bearings,plinths,tweak after tweak,
At some point you will find bliss. Then you get audiophilus Nervosis possibly the inflammatory variant and mess it all up again.

Should be good enough to give you a sense of what what vinyl can do. Also depends on what CD player and phono cartridge you are using, but the Regas should sound "different" in any case.
