I was once exposed to the same recording in two different media: vinyl LP and CD. Listening to them both was an eye-opener: I couldn't hear the difference on high-grade equipment unless the volume was cranked high enough for me to hear the needle riding in the groove between tracks.
I still have my LPs and still occasionally break out one or two that haven't been released on CD, but for the most part, I listen to CDs and mp3.
But I do sample my audio rips at insanely high rates; my 32 GB mp3 can only hold about 1,700 tracks...
