Physical explanation of amp's break in?

Recently purchased Moon i-5, manual mention 6-week break in period, when bass will first get weaker, and after 2-3 weeks start to normalize. Just curious, is there ANY component in the amp's circuitry that known to cause such a behaviour?

I can't fully accept psycho-acoustical explanation for break-in: many people have more then one system, so while one of them is in a "break-in" process, the second doesn't change, and can serve as a reference. Thus, one's perception cannot adapt (i.e. change!) to the new system while remain unchanged to the old one. In other words, if your psycho-acoustical model adapts to the breaking-in new component in the system A, you should notice some change in sound of your reference system B. If 'B' still sounds the same, 'A' indeed changed...

I could be wrong ,but, I think some Sony TV's are made in the U.S.A..
Some business practices commonly associated with Japan are actually the result of American minds.
I think that Sean is right about break in. Loudspeakers often sound quite awfull out of the box, then settle in to produce the sound we expect for some time. To borrow an expression/analogy from finance, it is much like the bathtub effect. Initially products may often demonstrates a wide vacillitaing quality, then settles in to perform with more consistentcy for much of its life, and then due to age,wear,etc., starts to demonstrate varying quality (though not necessarily identical to the break in period) till it fails.
