Why no “Break in” period?


If people say there’s a break in period for everything from Amps to cartridges to cables to basically everything... why is it with new power conditioners that people say they immediately notice “the floor drop away” etc.  Why no break in on that?

I’m not trying to be snarky - I’m genuinely asking.

Dear Mr. Millercarbon sir,

I know it is a bit past Thanksgiving, but I am so thankful that I don't listen
to my system (or any for that matter) the way you listen to yours.

Best Regards,
Barts
Earlier: I posted, "I should have mentioned what a waste of keystrokes, I now believe it to be, to engage (a polite, scientific, term I’ve coined, for rock-headed individuals) and their blather."      Apparently, someone felt that was, "offensive to a member"(probably, because they couldn’t understand it) and deleted it, though the post addressed NO ONE, in particular.      Welcome to the CANCEL CULTURE.     Let me expand that, to ALL the blather, generated on this site, in general.      Is that more acceptable?
litho=stone
cephalic=head
lithocephalic=head full of rocks

Example: One way to come off as pretentious is to use big high falutin words like lithocephalic when plenty of words like dense, dull, dim, etc will do.
also beware of anti-expectation bias, as you may prefer to not like it  so that you don't have to buy it...
