When have A/B comparisons led you astray?

I am curious how others have made A/B comparisons within their systems. What errors are encountered in this test? How do you avoid them?
I often think of my stereo system as a pair of ski goggles. Have you ever worn a pair of amber ski goggles all day and then been shocked at the colors presented to you when you take them off?
How does this phenomenon translate into the realm of sound?

Same mechanism. Neural adaptation and it is a common source of bias in long term even more than with A/B comparisons.

I recall a study done at a hifi show. Subjects made a blind preference choice between two options (speaker vs. speaker, or tube amp vs. SS) in a level-balanced setup. In every two-way test, the subjects preferred the second choice, regardless of what it was.
