Tim, yes, perhaps "all they really needed to do was sit down, shut up, and listen to entire albums." But they didn't. Perhaps, there is more to it and perhaps they think not particularly good systems and even worse tables sound better than their digital MP3s and ear buds. Yet you talked to them and they said they were into the sound. Why not just accept what they are telling you?
I think it is pretty exciting and vinyl sales figures don't lie. That is a measurement that can be taken to the bank.
Oh, I do, sort of. We all know vinyl sounds different, so if they really didn't like the sound of it, they wouldn't have made the investment to be able to play it. But I think the experience of actually listening trumps whatever difference there might be, and personally, I think the experience of a server, of putting everything in your collection at your fingertips is the best. I can listen to whole albums, I can make artist playlists, era playlists, genre playlists, playlists of new material I'm working on for the band...I can use Apple Music or Spotify to find many covers and arrangements of the same tune... I made a list recently of Steely Dan songs with my favorite guitar solos, so I could listen and compare the technique, phrasing and melodic structure of the playing of Larry Carlton with Skunk Baxter, with Walter Becker, with Denny Dias, etc. Pointless for many, but useful for me. The digital music experience is whatever you make of it and it is so easy it's almost effortless. But if some folks need the limitations of records to force themselves into a quality listening experience, I think they should get the records. Or some ADD meds. If they like the way their turntable sounds better, that's a bonus.
