Burn in vs perception


Posting here in speakers, but could probably go in any of the forums. Question of the night: how much of burn in of components is actually burn in of our perception? That is, is burn in partly us becoming accustomed to a change in sound.
 

I’m listening to my SF Amati Traditions that at first I found a bit strident, but I now find lush, dynamic, and generally brilliant. I bought them as 1-year old demos so theoretically they should have been played enough to be broken in. I haven’t changed anything in my system—I have been working on my room with more stuff, but that’s it.

Sometimes reviewers or arm chair audiophiles (me) will state that said component needs to be plugged in and left alone for weeks until it gels with the system. Could this simply be our own perception burn in OR is something real happening here?

For speakers I can buy it (woofers need to loosen up and all), but I almost always buy used, and I almost alway a) find a difference of a new component (good or bad), and b) in time, I couldn’t tell you what the change was. Maybe just me, but our brains are pretty good level setters.

I willing to bet this can be a large part of “burn in”.

I decided to be nice today.  So as I read these various threads, I just kept quiet.  But then I read your post and I nodded approval.  So technically, I just fell off the wagon.  Therefore:

What is it with these people clacking away on their keyboards spewing nonsense.  Of course gear has burn in and cables have burn in as well.  Why all this, "well if I can't hear it then it doesn't exist."  Where did all of these Luddites come from?  Scratch that.  Where did all these theoretical physicists and PhD's in Electrical Engineering come from?  

The new power cords for my amps took two weeks to settle in.  The first 8 hours they sounded good.  Then they got so bad between 8 and 30 hours I could not even listen to the stereo.  I turned the volume down and walked away.  After that it might sound good one day and bad the next with the variation diminishing over the second week.  Suddenly one day the system sounded amazing.  But for a week or so I was starting to think my purchase was a mistake.

My HT system is mid-fi.  I have some decent Monitor Audio Gold speakers and a Marantz receiver- killer OLED monitor.  I bought some speaker cables for a few hundred dollars- didn't hear a big change.  Bought some good AQ HDMI cables in the $100 range.  Saw a little improvement, maybe in the picture but not in the sound.  The big changes came when 1) I moved my Furman Power Conditioner to my HT system.  That made a big improvement in the picture but I didn't notice much difference in sound.  and 2) ran an ethernet cable to my Apple TV box from my expensive audio grade network switch.  Again a large improvement in the picture.  The sound is good.  Typically, I wouldn't expect a mid fi system to have the resolution to reveal anything but the largest of changes.  For some reason I demand near perfection in my 2 channel but with HT I'm more concerned about the picture.  As long as the explosions shake the room and the dialog is clear, I'm good.  Maybe it is from growing up with a 19" B&W TV.

And to you sir, kindly explain what this wire electrical phenomenon has to do with audio ?

Well, for starters audio uses current/voltage to reproduce sounds.  With wires.

Btw- if you really have a 1971 GTO 455HO, I respect that.

If you don’t, please change your username.

That’s ok.  I dealt with the technically illiterate throughout my career.  My favorite were managers who would solicit opinions from everyone about a technical matter.  They either felt the correct technical answer or else they determined the correct technical answer by a majority vote.  Almost always wrong although statistically, a group might sometimes vote the correct answer.
