No, it's worse than that. It's possible to create a reasonable
environment even for subjective listening tests - careful AB
comparisons with equal volumes, switching between A and B at the
discretion of the listener, warm up period before critical listening,
comparable parts (bell wire - what a joke) etc etc. It seems that the
demonstration went out of its way to police the listening tests so that
none of the above were possible, therefore worthless even in terms of
subjective listening, which was no doubt the intention.

I don't think they were being devious. They just hadn't thought about
it. And the bloke detailed to set it all up couldn't care a monkey's.
