I had beta because it was better. I had sacd because it was better. I used MQA with tidal because it was better. The same reason why some think analog is better (tt) than digital.
The biggest complaint about all the above was that people didn’t want to repurchase what they already had. It was never about the better quality product, which beta/sacd was clearly superior), it was always about $$$. Same goes for anything you buy today. Why do most people buy a Toyota or Nissan instead of the truly better car Porsche? $$$$!! A lot of analog loving audiophiles have 4-5 digits invested in analog, then they spend $1000 on digital and complain why their digital setup doesn’t sound as good as vinyl. I see this in reviewers (1 particular reviewer does this at stereophile), but I also see it here and in other forums.
Most people don’t want to buy the best or better quality item because they don’t want to spend the $$$$.
