I once heard a story in audiophile community, I don't recall the particularities, though. Guy went to audio exhibition and there was one booth with curtains covering the actual product. This is a new WIP product, we want to hear feedback without you actually seeing what it is to get a bit more objective response. Audience listened to some music playing from behind the curtains, discussed various strengths and weaknesses of the audio system. After a while curtains were raised to reveal live acoustic band playing. Instruments themselves are imperfect, there is long chain of devices (recording, mixing, playback) until the signal reaches speakers (and then room until signal reaches ears), at higher quality levels it is quite often the case of how well all the inaccuracies of the system interact with each other, rather than how accurate certain components of the system are.
