I don't think you can make some people notice (certainly not care about) sound quality. Just can't. They have rocks for brains or something.
I remember when I was younger, I'd walk past the TV section of Sears with my parents when we went to the mall. I'd say, "This TV has a greenish tinge, this TV has a reddish tinge." They would say "Looks the same to me. How can you even tell?"
Apart from music, I didn't start noticing little differences till I became very close friends with a clinically OCD typesetter. Once you can notice, it's hard to forget to. Eventually, I force myself to accept things that are only very good, but not without feeling a little disappointed.
