Product comparisons are not scientific experiments.


Well, they can be performed with scientific controls
for bias in place, as is done in marketing research
and product development. The rationale for this is
the the same as it is for basic scientific research.

It is pointless to
try to insist that they are. When someone is listening to different
products in the shop or in his home, it is perverse to insist that a
full scientific protocol be carried our.


Indeed. And I haven't in fact seen anyone insist that.

I have seen loads of audiophiles concluding that two things sound
different, simply because they did a nonscientific product comparison.
Often this isn't sufficient evidence for such a claim.

Audiophiles don't like being told that, but it's an entirely
uncontroversial fact, to a scientist.
