click on December 2006 and it will open.

Sorry, yes, that's how I did it too. Go to the front page first,
then click Dec 2006.

That's a good phrase. Not very good testing methdology. Where's the
variance numbers for multiple tests? Where is the statistical analysis
of those variances? Where are the ambient temperature, pressure and
humidity readings? His blithe statement that "the measurements were very
consistent" means nothing.

can one expect these data to reflect real-world audibility?

With that data, who knows? The article references another such test
(http://www.vikash.info/audio/audax/break-in.asp) that gives slightly
better data. Notice that the before and after numbers aren't much higher
than the inter-test variance, and in some cases lower. The author of
that paper makes the error of believing that an average will somehow
eliminate testing variances. He needs to learn a bit more about
statistical analysis.

The entire conversation about burn-in seems so ridiculous to me. If
burn-in makes an audible difference, what happens if the burn-in period
makes the driver a poorer match to its enclosure? If the manufacturer
altered the enclosure to match a "burnt-in" driver, what happens if that
driver doesn't change enough? Yet, somehow, they all assert that burn-in
will always improve the sound. Sounds like some serious fakery (or
idiocy) to me.
