My local cinema, i think it's either ugi or cineworld now, about 10 years old I guess, sounds fine, not enough bass (though I blame the room acoustic) but very good clarity.
I care only a small amount about the quality, as long as i know whats going on and we're not splitting hairs, i'm ones of those guys who cares more about the music playing rather than quality of it, i still got most of my old vinyl and an old record player my parents let me have when they got a cd player. Which most audiophiles would throw their hands up in the air at, oh well, i like it.
