It's called listening fatigue. The break that you give yourself so doing
allows the ear to recover. Now try it the other way round !

Hmmm I read somewhere that the opposite is usually in play. There seems
to be a common bias to prefer the second smaple in an A/B comparison.

Actually it seems that was what I was saying ! I wasn't thinking of an A/B
comparison per se actually but I can well believe it.

Interesting becuase i always thought listener fatigue happened after
extensive listening, that would be the B in an A/B comparison




Yes. This is a ploy used in some demos. Also if you can make the second
a little louder, this too will tip the balance.

Yes. I had the trick about the level tweak explained to me by a guy who's
familiar with hi-fi reviewers a couple of weeks ago.

Works every time apparently !

No just most of the time.
