However, I think it needs to be said that long term listening has
been thoroughly investigated under DBT conditions, and found to be
very insensitive when it comes to reliably perceiving small audible
differences.

And it precisely this difference that keeps people wondering
about DBT's.

Why? Is there valid, reliable a-priori evidence that DBTs fail to detect
audible differences?

Equipment that supposedly sounds identical
under conditions of DBT's gives different levels of satisfaction
long term.

Isn't there more to audio equipment than just sound quality?

And you must admit, while possible to do so, it
is unusual for DBT's to be done with switching done on a scale
of days.

Once one finds that something is futile, one is not encouraged to spend a
tremendous amount of time with it.

So should we be so surprised that a method developed and
found most telling under short term comparisons gives
different than expected results when used for long term
comparison.

There's no reliable evidence that this is the case. Indeed, there is
reliable evidence that this is NOT the case.
