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?

Some years back I bought a $300-ish NAD cd player for my 2nd system. Just out of curiosity, I did an a/b against my twice-as-expensive Music Hall which was my "good" player at the time.

Based on that comparison, I thought the NAD did most things better, and after switching back and forth for a couple hours, I decided to keep the NAD in the better system, and put the Music Hall upstairs. A couple weeks later, I realized that I was never listening to entire cd's anymore. There was something missing with the NAD in place. It sounded good, I always got bored quickly.

Eventually, I switched back and found that I enjoyed the system more with the Music Hall, even though I couldn't identify anything it did better. So whatever magic that player had was apparently too subtle to pick up on when doing a/b comparisons. Lesson learned is that for me at least I've got to give a component enough time that I'm really just listening to the music.

By the way, I still have both players, and it's really a crap shoot as to which will work better in a particular setup. Turns out the NAD isn't inherently boring-it just was in that particular setup.
