In addition to mere "it's in your head" there's some tiny bit of evidence for actual psychosomatic effects. That is, the mind influencing your body to act differently.
It's been a very long time since I took Neurology but there are some muscles around the ear drum. If you have ever been in a situation where you were scared and MUST hear better, you may have heard them activate.
It is possible, but completely unstudied, that when audiophiles change something, they activate these muscles, improving their low volume hearing until their ears get tired and revert to normal.
Of course, you are free to disbelieve, but at least it's one plausible reason.
