Long time ago my brother auditioned speakers in audio store. Salesman stated that first speaker is so good, that basically there is no need for anything else and it sounded good indeed. Then he presented more expensive one just in case "if my brother’s hearing apparatus is superior". This speaker sounded better than the first one. Then he presented top of the line speaker that sounded wonderful. He left my brother in silence for 5 min. serving other client and then offered one more speaker that is less expensive, but as good sounding as the top of the line one - a real bargain. It sounded great and my brother bought it. He found later that it was the first one he listened to. It was twenty years ago, but he still likes them (Cabasse).
There are so many factors involved, including suggestion (placebo effect), passing time, amount of time in between, music piece etc. that it is difficult to tell the difference. I’m pretty sure all speakers don’t sound the same, so Richard Gray’s experiment shows only uselessness of the method.
