I didn’t no. What really cinched it for me was a DAT player we had in the shop. I took the output from a system with a maxed out LP12 and did a test to see what gets “lost” in digital. But the funny thing was, the output of vinyl, recorded to digital and then played back sounded exactly like vinyl. All the warm colouration and immediacy people love about vinyl can be encoded faithfully for digital reconstruction. That was the day I learned vinyl reconstruction sounds the way it does because it has to. Whereas digital sources often sound the way they do because they can.
Reel 2 reel is the only analog source that blew me away.
