An interesting demonstration

I’ve recommended James " JJ " Johnston  who is in the video as one to read before but he doesn’t say what most want to hear on this forum. He’s a regular poster on ASR if you wish to learn about Psychoacoustics you can read some of his papers.

@artemus_5 , It is very hard to take Paul Mcgowan seriously. This has nothing to do with the topic which is Poppy's demonstration.

djones, thanks for the link. I have run into him before but have not read him extensively. I will trundle through these articles. I'm sure he is antithetical to the mythology advanced by many audiophiles who insist on taking their own hearing seriously. One should never make a determination after one "trial" of unblinded hearing. The simple truth is that if it looks better it will sound better. If it costs more it will sound better.
Neither cost not looks is a determinant of sound quality. I use to sell cheap Marantz receivers (we got spiffed on these) by blind ABing the customer with expensive Accuphase separates. They could never tell the difference and happily bought the Marantz when they discovered it sounded just as good. 

@mijostyn, In your opinion, did the Marantz and Accuphase separates sound the same?

OK I listened to Poppy. The demo of Stairway to heaven, etc is something I have heard before. I wouldn't  call it mind bending. Someone had to hear the words first. then write those words down so it could be shown on the screen. Is this what you are calling "suggestion" of what we hear? Yes, She is suggesting. But she has  gotten her "suggestions" from someone who first heard the words and wrote them down.
