Why no “Break in” period?

Actually it’s very difficult, for speakers, to separate out the effects of diaphragm break-in and the effects of break-in of internal wire, speaker cable, internal crossover parts like inductors and capacitors. You know what they say when you ASSUME something. It makes a fool out of me and Uma Thurman.

Thanks for all your thoughts related to my question.  I really do appreciate all the knowledge you all pass on.

"expectation bias"

?
This is practically a standard of movie reviews. How many times have we read about the reviewer coming into the movie not knowing anything about it? Or how the movie was nothing like the trailers? Or everyone said wow best movie ever, changed my life, another Marvel, the first two Guardians were great, this Star Wars was "supposed" to be, and so on.

Its a standard thing, right? Everyone knows what I'm talking about, right?

Which means you also know the very next thing to follow the expectation is the BUT and the HOWEVER or every once in a while the AND IT WAS. Right? This is something every single person on the whole freaking planet understands. We all know this, right?

Further beating a dead horse, driving the point home, like a stake into the vampires heart, we all know that the reviewer is perfectly capable of then writing about his actual experience of the movie IN SPITE OF EXPECTATIONS!

Sorry about the all caps but when you have someone so unbelievably dense they can't understand what everyone else on the planet just automatically gets its like all sense bounces off the skull until you're shouting in vain to get through. Probably other side of the impenetrable skull is vacuum. Let's see if it can learn. 

Don't hold your breath.

"Bias" is bias, regardless of the viewpoint or subject.     ie: Those that are so adamant, regarding their beloved theories/opinions/biases(regardless of the source), 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.

I have no idea.

I can say with personal experience I've run into and not run into break in periods with different components. Here are components I've heard break-in or extended warm up time:

• Mundorf MKP capacitors in speaker crossovers.
  
• IcePower Class D amp modules
  

Here's one I haven't:  Luxman integrated.


The interesting thing is that a number of independent audiophiles have confirmed to also have the weird, very long Class D warm up times. Why the Luxman does not.... I have no idea. Perhaps the high current at idle leads to faster stability of the active devices?



Best,
