I would suggest digital is no longer a replacement for vinyl. Digital is now a replacement for radio. Streaming has killed CD buying - if you want great, clean sound but don't want to deal with scratched CDs, shelf space issues and crap plastic jackets, streaming is the way to go. But for me at least, streaming is more for "put something on while cleaning the house/reading the paper/driving the car" kind of thing - like radio. If you want a great, special sound, vinyl is a good choice. More for relaxing with a beer, sharing a musical experience with a friend, settling down for a critical listening experience, etc. IT also gives you the chance to go to stores, dig through stacks, etc. Sound quality ranges - I've got crystal clear sounding vinyl as well as a few with snap, crackle and pop - but as I get more experience in what to look for, I've definitely gotten more ofr the former than the latter.
If folks in the market are building more machines from scratch, that means they say a payday for it. Which means the revival, if a fad, is going to be a multi-decade fad. Unless nuclear war or whatever.
