Why no “Break in” period?

Politely attacking somebody is still attacking.  It seems like millercarbon has received a lot of that, not that I am agreeing or disagreeing with him.  Hiding under the umbrella of "politeness" is not going to cut it with me.  

some manufacturers do burn-in their components or cables before shipping...I know my Zu speakers will have about 100 hours burn in, and I see longer on their more expensive speakers...

For those who believe that one cannot remember a sound, tell that to someone who's pitch perfect and can tell you instantly what note is playing. 5 in 10K people have that ability. The rest of us come close.

We can remember sounds. Ask any early hominid if he remembers the sound of that big cat who ate his friend last week.

Everyone (pretty much) who makes electronics "burns in" their equipment at least a few hours, sometimes even 24 or 48 to eliminate early failures caused by component anomalies and manufacturing defects.


I think they mean reforming. When an electrolytic capacitor sits unused for a long time (many months to years depending on quality), they can develop high leakage current due to aluminum oxide formation on the foil electrodes. That can have bad effects including circuit malfunction or worst case capacitor failure. Reforming is applying the rated voltage with current limiting to remove the oxide. Modern electrolytics can go years before this is a problem. If the manufacturer has good controls, they will use a FIFO system for part usage and should scrap older electrolytic caps.

Andy2, best rule in a forum, attack the content, not the person. It is a simply rule to follow that many don’t seem to understand.

"after the manufacturer’s burn in." ????

For what purpose would a manufacture need to "burn in" a piece of electronic equipment, wasting his/her time and money for such a purpose?

Circuitry adjustments yes..... "Burn in", though?? Again for what purpose?

What is meant by "forming" of an electrolytic capacitor?

nonoise,
What you are describing appears to be mainly recognizing a sound, which is different from remembering subtle characteristics of that sound. You can recognize a sound or image even when it is very distorted, like a persons voice on a noisy phone line, or being able to read sentences even when every 5th character is removed.
