My experience too. The ProAc Response D15s I bought a year ago sounded
very different to the demo pair for about the first hour of operation
but settled in to the familiar sound after the first day or so. Some of
that may have been my ears/expectations but not the first 60 minutes.

The dealer had previously tried to sell me the thesis of needing up to 6
months "running in." I think he was trying to "manage" no-fault returns.

BTW, I looked at the ProAc driver manufacturer's web site and they
recommended two hours of running in for brand new units before testing
their parameters.

It's so boring watching true believers pile onto each other with more
ignorance and error.

For your information, I would agree with others that I hear very little if any
difference with so called 'burn in'. "People who use valves" are no more
predictable than "people who use cars"

I'm willing to accept it's *possible* for a speaker to change slightly
with use. However, I'd expect a decent maker to do this at the factory
before final quality check if it is a real issue.

It may come as a surprise to a few here, but the minute you start to use
*anything* in this world it's 'physical characteristics' start to change and
it starts to wear out....

If we observe a speaker and measure its performance then, in doing so,
aren't we altering its behaviour ;o)
