Part of the problem with the blind-test brigade is that I have been in a position to be vulnerable to expectation/confirmation bias many times ((over ~40 years in the game), yet there have been more than a few that failed to produce the "expected" result.
I don’t doubt that such biases are frequently responsible for the positive reactions of audiophiles who are assessing newly acquired gear, and I am certainly not immune. But if it were so simple, and the biases so predictable and strong, then why have I, and countless others, no doubt, been disappointed with components when the opposite would be expected?
On a tangential note, regarding blind testing, I do not believe that listening to short passages is necessarily fair, or best-practice. I have been able to distinguish between components when allowed to listen to full songs with which I am very familiar, but not when confined to snippets. And I know that others have had similar experiences.
