....in a related manner, yet it's not about audio equipment. Maybe people who believe a $6000 amp or a fancy crossover MUST be better should Listen to this NPR story.

I don't know I would even consider that as a single blind test as the researcher said this to his subjects
"These are all fine violins and at least one is a Stradivarius. Play, then judge the instruments."
They should not have been privy to such detailed from the researcher that "all are fine violins" or " at least one is a Stradivarius" especially if the goal is to see if a Stradivarius is preferred. The subjects should not know ANYTHING about the violins even in a single blind test.

No; there's no requirement that the participants be unaware of the items being tested, except during the actual blind testing, of course. Here, since the violinists were to pick the Strad, they obviously had to be informed of this.
An example of this relating to audio equipment is the Stereo Review amplifier blind listening tests which have been cited here several times. Not only were the listeners told of the amplifiers($220- $12,000), but listened to them openly before the blind sessions, of course reporting many areas of superiority in the more expensive units, which disappeared when the labels and price tags did. This significantly increased the value of the test.

I disagree. You don't tell them anything and you don't need to tell them anything about the violins. All the need to know is pick the violin under whatever methodology they have set forth.
Double-blind testing does not add ANY bias from the researcher to its subjects and the subjects need not know anything what the researcher is trying "to prove" and that is precisely what the researcher did in this case.

Again, that wasn't the purpose of the test.

I know what you mean JohnK.
My point is for them to influence the subjects like that and call it a double blind test is academically dishonest.

I think the take-away quote from this article -- and one that applies equally to speakers -- is this:
"If no one can tell the difference, what's the point?"
You all know the thread I'm talking about... I like the way Axiom slowly iterates their speakers toward that unreachable goal of perfection. With data and testing. Sure, they could add more bracing, but does it make an audible (positive) difference? They could also make their crossovers prettier to look at and/or use more expensive components, but would that make an audible (positive) difference?

Besides audible benefit, another thing parts quality can impact is longevity. While I personally upgrade so often that it probably wouldn't matter, I still think it's cool if the stuff I buy is going to last indefinitely. If "higher-quality" parts increase the longevity, I'm all for that, even with negligible sonic improvements.

I agree with you CV, I hope all the parts inside anything I buy will last as long as I need them to.
