Why no “Break in” period?

Uh....these:

while refusing to acknowledge that ONLY experimentation(the heart of the Scientific Method), provides PROOF, regarding anything discussed. Most of those are proffering their opinions, without ever having tried what’s being discussed. What you hold true, in your listening room, is all that matters. Experiment and trust your ears. Anyone that discredits another’s abilities to hear improvements, in their own systems, in their own listening environments, with their own ears, should be considered condescending, insulting and/or(probably), simply projecting their own ineptitude. Perhaps, to be pitied.

Are you unaware that the above quote constitute a series of "claims?"Ones that you have continued to make?

Again:

If you and I sat in front of the same system and swapped, say, power cords, and you think you heard a difference, and I think I heard no difference....on your view...what does this tell us about the actual piece of equipment we are "testing" this way?

In your view, would such a "test" imply the cable did in fact change the sound, but only you heard the change? Or....what?

If we care about what is actually happening, whether a cable (or tweak) actually DOES change the sonic signal, just saying "try it for yourself" as if that will decide the matter is of no help, if "trying it for yourself" can yield contradictory results for different people.

Why be so resistant to these perfectly reasonable questions about your ideas on this question?

I sort of think we are chasing our tails here and Andy you really need to put that stuff down.
Oregonpapa, a new tight belt may slow certain types of motors down fractionally turning some energy to heat so there is a rational for the change in sound. Although I must say we are very bad a discerning slow changes. We are much better with abrupt ones. If capacitors "break in" at all it is withing seconds to a minute of being charged for the first time. That would also be a pretty bad cap as their performance is specified to be within a certain percentage. They may deteriorate over time I have no idea how fast. I'll have to look that up. As I said before the most variable and unpredictable part of any audio "system" is the brain that is listening. Think of a viable reason why something would occur and test for it. In the turntable with a new belt case just check the speed when the belt is new then check it every 24 hours and document the speed change then buy another belt and do it again. One of the most important characteristic of a scientific fact is that it is repeatable. 
Prof, I have come to the conclusion that Geoff can not slow down. He is bipolar 1. So don't blame him he is not responsible for his actions/words.
Geoff, yes I agree. Vinyl sounds better but you really have to stop counting the revolutions:)

If it talks like a newbie and walks like a newbie it’s probably a newbie. I won’t mention any names, but they start with P and M.

geoff, geoff, geoff,... They are the victims here. Just trying to teach us that we can't possibly be hearing what we are hearing. 

BTW mijostyn, are you a doctor of capacitors or does your knowledge just automatically apply to capacitors? The reason I'm asking is capacitor companies (these are people who made there life profession, capacitors), state there is a break in period.

Who is "they?"
Me (in this very thread):

There is of course nothing wrong with just buying gear and trying it, feeling like it makes a difference we like, and buying it. As I’ve pointed out a million times, I don’t go trying to test everything I buy with scientific rigor.

.....

I am not saying you are wrong in your claims. I’m actually open to the possibility of fuses sounding different, burn-in etc.

And I pointed out I hadn't come to a firm conclusion on the matter myself.
