Spot on about the orchestra. A chap used to know used to work for Midas and said that visuals affect perception of quality significantly. They had a problem with a digital desk where the UI was running at very slow framerates and the customer complained that it sounded terrible. If they turned around and listened without looking at the screen they thought it sounded absolutely fine - merely seeing the flickery slow framerates made them believe it SOUNDED terrible. And you're right about the inability to improve. Try reading up above where people are arguing that they can't hear the difference between a WAV and a 128 kbps MP3....!! Either their hearing is absolutely shot or they are listening to silence.
