It’s fake nostalgia of an era they never experienced. Vinyls always sounded like shit but we had no comparison except the better sound of movie theaters, but you couldn’t have that at home.
Then the audio CD appeared and it was like the second coming of Jesus. The sound was really a hundred times better than vinyls, even with the same set of amps and speakers.
One day they’ll tell us that VHS on a small black and white TV is better than a 4K movie on a giant screen.
