Perhaps one of the most famous examples is the infamous Carver challenge published in Stereophile. Its entire premise was indeed that the amplifiers sounded different, but that Carver could get his to mimic the sound of the other. He succeeded, but apparently couldn't replicate the results in actual production.
... these tests have failed to reject the null hypothesis - listeners can’t tell the difference between cables/amps/resolutions using only their ears. The point here is that there have been lots of tests, and they all fail to reject the null hypothesis...It’s not even remotely true that all tests "fail to reject the null hypothesis."
