Burn-in time Vs. Getting used to a sound

Electronic components, just like us humans, suffer stress and strain. When electronic components are "powered up" all sorts of changes occur between their static (ie unpowered) and active (ie powered) states. These changes (particularly in high-end audio components) CAN and are "heard", as others have stated in this and other posts. Maybe there are some people around who cannot differentiate these (sometimes subtle) changes which affect the signal we hear, but although these people have a right to say "BS, there ain't no differences" it does show a somewhat narrow minded attitude which is contrary to the majority of those on this site who enjoy all aspects of reproduced audio and have a wiser, broader view of this hobby.

It is a FACT:Burn-in time is for real. Even after 3 years worth of break-in time, my solid state components need to time to burn-in for optimal performance. I turn on (CD,preamp/amp)an hr ahead of listening time(no music playing). 20 minutes in to it, sound approaches acceptable. An hour in to it, it gets better. Two hrs in to it and the system really sings. May be there is an objective reasons, how the electronics work.

Do headphones need time to burn in? I just bought a new pair of Sennheiser HD 580s and am wondering if anyone noticed changes in the sound of their 580s over time.

listening supports my view not what someone else says. Burn in is for real, no BS.
