The reason I was thinking physical proof of ordinariness might help at least some borderline audiophools steer clear is that they don't trust A/B/X, and if they're smart, for good reason. Subtle audio effects are hard to tease out using even the most carefully arranged A/B/X, a problem apparently caused by plain old fatigue from the listening effort.
Well, let's get the Streisand effect started, shall we?
This above sentence is utter bullshit. The whole point of ABX testing is to determine if the subject can tell a difference. If a supposed audiophile can't tell the difference, it's because there is no discernible difference. Chalking the lack of result up to "listening fatigue" is bullshit - that's saying "I was trying so hard to notice the difference that I couldn't notice the difference". It's circular bullshit logic at it's most laughable.
So audiophools are not smart to distrust ABX testing. They are idiots for distrusting it.
And it seems like you have an ulterior motive... there always seem to be people who bring up audiophool bullshit, then give some passing compliments to the industry or make some accommodations for it... like "well, you can't trust ABX testing, though" above. People who understand logic and science and know audiophoolery is BS wouldn't waste time debunking it anymore than they would waste time "proving" to someone that their faith in some phantom god is equally foolish. Because those people don't want to know the truth - they want to believe.
Dave doing a whole series of videos isn't going to change these people's minds because their minds are defective from the start. They lack logic and reasoning power so how can you use logic and reasoning to convince them? You can't.
Anyone who loses money due to this audiophoolery stuff is pretty much a victim of their own stupidity. The only exception I'd make is the crap being sold at Best Buy or other major retailers... those consumers have a legitimate reason to believe the products sold are vetted and not outright scams, and they are also generally unsophisticated consumers. But I still have little sympathy for them.
