edit in my last post: meant to say experiments to date suggest it is difficult* or maybe impossible.
dalethorn, such experiments as you did with your grandmother are good to do, but unless we can prevent false positives, well, there's a chance of false positives
. There are certainly a lot of audiophiles who think there's a difference in 16 vs 24 or in cables, and they're entitled to that opinion, but until they rule out all false positives in a test they have to objectively admit the POSSIBILITY that they may be wrong. Skeptics ought to admit the possibility that after a decade of research apple may prove a difference. If you ask the question, But how can EVERY cable believer be wrong? Because no subjective listening test has yet been published that rules out the possibility of false positives. I think this is important to keep in mind, because trying to argue against the need for DBT using tests like you did with your grandmother that invite false positives is just going to attract more ire from the skeptics. I prefer to argue against the need for DBT with the sin of sloth
