It's when you examine the results that it ends up being that their identifications were no better than if they were guessing.
So it's not as if under blind conditions people suddenly say "Gee, I can't hear any difference."
A better way to explain it would then be the ability to reliably differentiate between cables drops as the listener has less information as to which cable they are listening to. So
- ''night and day' hype is only true when the listener knows exactly what cable they are listening to and has prior knowledge of that cable i.e. they have read and believe the hype.
- I heard a difference but it was small, but worthwhile means they know what they are listening to, want to justify to themselves the purchase of that cable but are not fully falling for the hype.
- I cannot hear any difference means the ears dominate and the hype has had no effect and they are not going to self justify the purchase.
- in a blind test, where an opinion is asked about any changes, they are invariablty small but worthwhile, as some of the knowledge needed to reliably identify the cable has gone. Here they are not actually asked to identify the differences, just comment on them if there are any.
- in an ABX test all clues to the cable have been removed and any knowledge of hype is useless and now people cannot identify a difference.
For me all of the above again shows the difference is in the listener, who they are and how they are listening to the cable. The cable maker has a bigger influence over the results than the cable itself, which has had no influence.
