What Exactly Does "Burn In" do for Electronics?


I understand the break in of an internal combustion engine and such, but was wondering what exactly "burn in" of electrical equipment benefits musicality, especially with solid state equipment? Tubes (valves) I can see where they work better with age, to a point, but not quite sure why usage would improve cables, for instance. Thanks in advance for your insight.

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.

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.

I get that, Al. I read an inference suggesting a below spec target goal in order to achieve the desired end result. It was disputed but I don't buy it. In terms of "measurable", I was referring to wires and cables as I'm sure you recognize. All in all, I think it went well:)
George is right.

But you need to let your computer screen break in to fully understand the concept.
