I am seeing a lot of interesting claims about burn-in issues, also audio
compared to other electronic equipment.

Those who has been trying to over clock a CPU, will know that often it
is
possible to tweak extra MHz out of the CPU, after it has been working
several hours. This would indicate to me, that YES computers do burn-in
as
well. However, nobody notice this, unless trying to run it above
specifications!

Saying that the burn-in issue is imagination, is something of a
statement
to
claim. I get the feeling that those who states "there is no such thing"
really does not have the equipment to reveal this very obvious
phenomenon.

If the "CPU burn-in" phenomenon is real, I guarantee that there is an
explanation
for it and that someone knows what it is - most likely the people who
designed
the CPU. CPU design is incredibly complicated, but it ain't black magic.
