Can anyone explain in laymans terms why your gear sound better after warm up

Is there and white paper that explains this "shkong"?  I am a believer I just dont know why? 

And " cleeds2" is right. Everything is better with beer. With the exception of tomorrow,

I know there is brain conditioning that happens with sound waves and your ears sending electrical impulses... be interesting if any ear specialist have tested this with Audio systems. Agree 100 percent with "
bsmg" Tubes are a different animal all together. I have had my share.

Your perception of loudness changes as a protective measure so you dont blow out an ear drum... It will not stop over pressurization in the "Specta Inner Pinna" of the ear. But it will try to compensate. The Human anatomy is a pretty amazing thing. I think John Dunlavy tried to understand this as he was designing speakers.

Thank you "Test pilot" now I hearing a language I understand. SS gear should be rated at an optimal "Operating Temperature"  then... Be interesting if the ambient temperature (the gear was pre heated or your house was lets say 110 degrees if that was perfect for the SS gear prior to electricity was applied) would change SS sound in any way.

I stand corrected and applogies Mr. Cleed.. " Is it the beer or do speakers/electronics really need some extended warm-up period?" 

You were making reference to my post / question...

Pretty sure its gonna take an PhD EE X 3 / Designer or Nelson Pass to give us a real answer here about Solid State gear and warm up . And I personally think music sounds better with beer. Haha! Please lets not debate Amber or Stout.

THANK YOU "Millicarbon", for the interesting and informative response! I got about 85 percent of what you wrote and will research the other 15%. If we ever meet at an Audio show or somewhere else Amber or Stout its on me. Again Thank you for the kindness and education!

Yes... that will make your head hurt! love "2D" that was coined in the posts. Fascinating read... Thanks for the head ache... haha Just kidding I enjoyed it! Straight Vulcan Science Center. 

First off Thank you all for the detailed information and debate. I have
no idea what the average age of an Audiophile is? If I had to guess I would say roughly 50's. So that begs the question of Ear degregation and harmonics your are actually hearing. Are your Ears as good at hearing subtle clues as they were when we were 20? Doubt it. Pretty sure if you have spent enough time and money on this "hobby" You know good HiFi and not good HiFi but if your Ears are not calibrated like our equipment then that also lends to error or music mishap via bad equipment aka our Ears and the way our brain perceives sound. Just saying I am by no means any kind of expert. But I would be curious if there are or have been Audiophile Ear Exams... I know in the Military its standard procedure. Yes O311 Combat Marine over here. If I was in Arty I would be buying ART not high end Audio Equipment! haha

Again Thank You all especially to the owners that fund this site and the moderators that maintain it for allowing us to gain insite from actual users from across the Globe, Audiophiles and Music Lovers alike.Happy 2020 and Godspeed! To all Enjoy the music!
