It's different to everyone.
No it is not different for everyone when we have access to the direct, original sound source, however I admit it is theoretically possible some astute listeners using top flight gear on specially selected music can indeed detect subtle differences which elude other listeners using inferior, less resolving systems. This is why when I challenge people to bets [either gentleman's bets or for money when I can proctor the test] I always let them
pick the "top flight gear" themselves, and when possible [and I'm feeling generous] I buy the exact music of their
choice out of my pocket. I only feel generous when my gut tells me I'm dealing with a person with an open mind who is willing to accept they are wrong if shown objective evidence which contradicts their preconceived notion. Based on your posts, you no longer fit the bill.
Which is why I rescinded the offer. You had your chance and you refused. End of story.
The concept of audio transparency has been discussed by scientists since the very birth of audio and its use in advertising appears to have started with Edison. This ad is from 1918:
The listening panel is testing to see if they can hear a difference between the opera singer, Anna Case, and the Edison phonograph system she is leaning against playing a recording of her singing.
A well known [but actually only run-of-the-mill] cassette tape manufacturer called Memorex similarly used the concept of audio gear transparency testing in this TV commercial c. 1979:
Since Ms. Fitzgerald is turned away from the test administrators and doesn't know which sound is being played at any given moment, she is effectively performing a "blind" test.
When listening to a recording vs. the original source, if we can't tell the difference we have achieved "audio transparency" or as Ella Fitzgerald puts it when asked, "Is it live . . . or if it is Memorex?", she replies: "Beats me!"
Audio transparency, as related to digital compression schemes at least, is defined here
. It means "perceptually indistinguishable".
