My guess is that less than 1% of people care about the quality of the sound of music. It’s not that they don’t care about music…it’s just that music is mostly for background while they are doing something else.
I’ve introduced many people to good sound over the years and while they appreciate it… it doesn’t really float their boat.
Then there are the issues of cost and size. Americans in general seem to want smaller and less expensive… look how long it takes to resell big and expensive gear these days.
What are the solutions… that is the real question… I wish I knew.
My own focus is to buy well respected name brands that usually resell easily… but there are no guarantees.
