One reason why vinyls can sell better than CDs is because people with vinyl usually also have a way better equipment to play them through. Better amps and better speakers. CDs in car radios were a major selling point. MP3 for iPods. Vinyl is a home system or DJing. You can buy a lot of high end vinyl gear also. I buy vinyl over any other option because you get a big picture sleeve and the analogue sound of them playing but it's by no means better than CD which is already capable of more than human hearing can manage.And in 2020 vinyl outsold CDs... Tube amps will never go away.
However the bottom line in all this is the claim that "valve amps can't be modelled faithfully" is just no longer the case, especially in 2021. It's already moving towards apps. Imagine phones capable of Kemper. Profiling with them. Wireless out to a bluetooth monitor.
Tube television is much more complex than a guitar amp and yet do we really believe that look can't be done with computer fx?
Or tube radio for that matter.
Or Atari games...
