Why not? Actually, it might be as you say for some
individuals, but certainly not for all of them. I mean, some
of those engineer and pre-conception types have as serious
an interest in perfect-sound audio as you. 

And of course, this does not eliminate the fact that SOME
people who participate in DBT comparisons have
preconceptions that say that the amps should sound
different. When those people cannot hear differences, some
may wise up, but others will come up with excuses related to
stress, pressure, the weather, etc.

Your position only holds for those who have serious
preconceptions about amps sounding the same. However, some
participants have exactly the opposite preconceptions. Yet,
all of those participants are in the same boat: they cannot
hear differences with a DBT, assuming the amps are decent
and the levels are matched.

Yeah, but you seem to assume that everyone who takes such
tests and cannot hear differences have those preconceptions.
However, some, like you, have just the opposite. Yet, they
still cannot hear differences. Obviously, then, a
level-matched DBT is most dramatic when a guy like you
participates.
