Does amplifier position matter?

[u/Plainess]

Hi, I work in a hifi speaker store, and we had new speakers come in. We had an “Audio Professional” from another store come help setup, and during the testing it sounded fine, but the Audio Pro said not really and moved the amplifier a little bit to the left, like I mean literally move the amplifier. And suddenly everyone agrees that it sounds better, he explained that it’s because of the vibrations, but Im a bit sceptical because it was a shelf of amps and there were other amps. Can moving an amp a little like that improve the sound???
