What Exactly Does "Burn In" do for Electronics?

I get that certain technical specs are sometimes required and that there is a descending scale of quality. I was referring to the unmeasurables. You know, those invisible attributes that always exponentially increase cost more than materials and labor.

Nonoise, you didn't take that personally, did you? I was of course generalizing. No offense.

Infer, imply, suggest. Call it what you will but I know what I read. Perhaps you misread the previous post?

Csontos, I didn't know what to take and am sorry if I inferred incorrectly.
No harm, no foul.

All the best,
Nonoise

George & Peter (Csontos), I would respectfully disagree with what appears to be the logic behind your recent posts, at least with respect to electronic components (amps, preamps, digital sources, etc). It seems to me that implicit in your logic are the following assumptions:

1)The alleged breakin phenomena which you dispute would result in changes that are measurable, at the component level (as distinguished from the piece part level).

2)As long as the component measures within the +/- tolerances defined by its specifications it will sound as the designer intended, meaning that it will sound the same as his or her prototype sounded when its development was completed.

3)Therefore for the alleged breakin phenomena which you dispute to exist, the component must measure outside of the +/- tolerances defined by its specifications when it is delivered to the customer.

In the case of electronic components I see no reason to expect any of those assumptions to be true.
