As I recall it was RCA at the dawn of HI-FI who did a test using a live orchestra and a physical passband filter to garner listener response. The audience did not know whether the filter was in or not The results were that people found the orchestra without the filter sounded unnatural. Their conclusion was that people had become so used to listening to the limited frequency response of the radios of the day that the real thing did not sound right.
Caveat: That is my recollection. If I remembered wrong it still makes a good story.
