Why don't you think it was a double blind test? The manufacturer knew which speakers were being tested, but not which speakers at a given time. The manufacturer wasn't changing the speakers, the user was.

And I wasn't there, by the way, so you can save your inferences on me.

Also, I don't think ANYONE has said explicitly, as you seem to keep stating, that M80s would beat Revels in a double blind test. Only that one would NEED a double blind test to see whether they would or not.

Stop making car analogies. Jeezus christ, everyone stop making car analogies for everything. Macs are not BMWs, Axioms are not Hyundais, a woman isn't a Corvette, and Cheerios are not Lincoln Continentals.
