I’m with you, those formats didn’t take off because the discs themselves were expensive, they needed expensive equipment to play them, more expensive equipment to process that outbound signal with enough fidelity for a serious audiophile to tell the difference, and a serious audiophile to tell the difference. Most music purchases are destined to be background music people have on while driving, working, exercising or otherwise not paying rapt attention to the music. Which really aren’t circumstances that inspire people to drop a lot of money on equipment and media.
but surely you could tell the difference between 2 speakers and surround sound? That’s what I want: to hear classical music in surround sound
