Break in period

Grab yourself a pair (maybe not all brands) of the various single driver speakers on the market and spend some time with them and then tell us break-in is a myth. I have heard some changes in sound that had me downright scratching my head from day to day. From sounding like a cheap transistor radio to an open window to the music. From screeching shrill highs to almost no bass response, to a closed in soundstage to shunted dynamics and so on. It is one wild ride that anyone who's experienced dreads every going through more than once. I would swear my system was broken, it sounded so bad, had me checking every cable, tube, cord etc...trying to find an answer.

No, no, no. I've heard that business about "getting adjusted to the sound," and it's nonsense

well, I'm glad your opinion is fact.

Shadrone,

A quick question. Do you assume that manufacturers only use new component parts when they make their prototypes and that their designs are only to be heard with new parts. I think it is reasonable to assume they do not, and that your product's critical parts age to approximate those of the manufacturers prototype.

Or are you saying that parts aging never changes the components contribution to the sound?

BTW, how do you define 'significant'.

Lastly how did you determine the appropriate length of time for the breakin to occur. It seems to me that listening skills/experience/interest are more determinative of the length of the break in period than anything else.

For other naysayers......

Everything is new, degrades and dies. Changes occur. Those are immutable 'facts'.

Why do I seem to note that when believers post they always post regarding the equipment that they observed the break in occur. Conversely, the nay sayers NEVER give any specificity to support thier positions. I would like them to tell us:
1) What credentials do you hold
2) What experience do you have
3) What have you actually listened to
4) Under what circumstances did you listen to the equipment that caused you to form your opinion.

Tell us poor believers what causes you all to want to deprive us of out poor beliefs. Absent 'facts' to support your beliefs that is!

Let us hear from you, but no more one liners please.

S7Horton, next time how about printing my whole sentence, not just the part you think you can nail as not factual?

Well, thank you all for your input and replies. I guess I touched a nerve with this topic. Sorry about the disagreements. We're all at different experience and educational levels when it comes to high end audio, eletronics, sound, etc.

My conclusion is that it's probably a combination of your own ears and brain acclamating over time plus the materials inside the speakers themselves are perhaps changing a bit. Maybe the Kevlar in my B&W's become less stiff for example. Just a thought. I'll go along with the first responder of between 100-200 hours. I have to tell all of you that when I installed a PS Audio power port some months ago and replaced the junk builder's grade eletrical outlet, I heard and continue to hear a marked difference in the information and detail coming from my loudspeakers and amp. I know this has nothing to do with the "break in period" topic but to if anything caused the sound to improve considerably, that did it. I actually installed a 2nd one since my SW is plugged into a different outlet from the amp. Good stuff gents.
