Burn in vs perception

I own a complex headphone with two different cells one dynamical the other one Electrostatic...

The dynamic cell come full blown after a warm-in period of 10 to 15 minutes...

The difference is not illusory...No one hallucinate each day at the same hour and only about deep bass and bass... 😊

Then if complex components need warm-in , it did not ask for great brain work to deduce that NEW component which had never worked BEFORE as a WHOLE may ask for an adjustment time which can be audible with some components more than with others ...This is called break-in...

And those "objectivist" claiming that this is  mere placebo or subjective impression of stupid audiophiles need to read about PERCEPTION and his relation to phenomenon, Cartesian dualism is dead , and some Illusions are more real and meaningful than some material object... Anyway break-in is a physical observed and probably measurable phenomenon ...

An immaterial perceived  rainbow is more powerful most of the times in his effect on us than a grain of sand...

I have long believed it is your ears acclimating to the new sound.   In the case of speaker surrounds I believe that is valid but it is a short break in.   Is it even enough of a change to perceive?    Not sure about that. 

Example,   I just picked up an integrated amp.    I set it up in my main listening room.    First with my Forte and then with my Sonus Faber Concerto.   

The Forte sounded really good.  I switched to the Concerto.    Completely different presentation,   but it sounded good.   Thin compared to the Forte.    It took a while for my ears to accept the new sounds they were hearing.   Better ?  Worse?    No....just different 

A topic hotter than a cables and cones thread.  

If you haven't heard distinct changes in the sound of audio hardware from new to maturity you haven't purchased enough new hardware.  

I postulate, however fatuously, that "noise" in audio systems can be akin to "noise" in wetware, and that an audio system in all its total parts talks back and forth to itself until an improved unity and flow is achieved... or not.

I honestly just put FM on or hit repeat for a while and consider it good to go.   I'm sitting here listening to a pair of well broken in Sonus Faber with my new Cyrus i7XR. Amp.     

Sure it sounds better than day 1.  I'm using a pair of speakers  better suited than when I unboxed it.   Speakers are more or less in the proper position now .... and my ears have grown more accustomed to the change in sound.  I really don't think the amp changed ...  it was clear and detailed right out of the box
