The novelty isn't there. Most of the 50 yo and older group still came up in the time when good 2 channel gear was stepping out of the tube era where stereophonic recording was still a novelty. A stereo was prized possession of many young persons. So was a good collection of albums. A tape deck in the stack was an eventual addition so that your vinyl music could be portable. Tech has changed all that. Earbuds, streaming, wireless speakers have all changed the experience of recorded music, mainly due to the quantity and quality available in mobile and portable equipment. My first system, the only means I had to hear recordings for many years, was in no way portable. I had to sit in front of it and listen. Having a home system just isn't the priority as a means of enjoyment of music for younger people now. Two-channel listening is more likely to be introduced to them via earbuds and headphones, not via stacks of rack-width gear and loudspeakers. They have to be introduced to stationary listening. Vinyl is a novelty, not the necessary default it was decades ago.
Then there is the economic issue. Audiophile gear has become excessively expensive, and I am not referring to the stratospheric prices of extremely rare gear, just ordinary stuff. There are many more demands on the budgets of younger people now than there used to be, and necessities have become much more expensive in relative terms. Clunky, specific-purpose listening gear is going to have a limited appeal anyway, but going forward, it will be increasingly more so. It is a pity some commenters disparage "lifestyle" products when those are the products most likely to find an acceptable place in homes in the future.
