No it tells me people suck at these tests and our short term audio memory doesn't work well in these scenarios and these tests Null out actual real differences that appear in normal longer term listening conditions.
People fail these tests comparing things have have clear measurable differences in the audible spectrum. People just are not good at them and these are very different scenarios than normal listening conditions.
Examples?
Look, ABX is just a method of conducting double-blind testing, which is the gold standard for science. This is how differences are found, or not found, between many, many things. The FDA doesn't approve a new drug based on "Fred found Blissalot really alleviated his depression, while Pete said he didn't feel anything. And oh, Jim died." Audio is science, it is not an art. Also, you don't seem to understand how ABX and DBT works. Get an ABX comparator. Take it home with you. Now take a month to do the testing. Use whatever program material you want. Do ten tests or two every other day. No one's standing over you with a clock. No one's holding a gun to your head. Hell, no one will even know if you cheat. Except you, of course.
The sort of subjectivism you are talking about is what got audio to its current, pathetic state, from which it is still struggling to escape. And there are consequences: When a subjective reviewer, writing in a subjective magazine or on a subjective website, announces the qualities
he hears in a [DAC, amp, cable, tweak], qualities he has shown no inclination, let alone ability, to prove, he ain't helping.
Even today, people base their purchases on such reviews. So we're talking real money here. Someone who learns that double-blind testing showed people can't distinguish between a $10,000 DAC and a $200 DAC can make an informed decision. He might still buy the $10,000 DAC for the name, the build quality or the pride of ownership.
But it will be an informed decision. On the other hand, someone who suffers audio panic because he's been told that he will never hear what's really on the disc unless he spends $10,000 on the DAC
du jour may put his perfectly fine $200 DAC on eBay and start calling his bank to arrange a way to get $10,000 so he can get the best he's been told there is. When, in fact, the "best" might not sound any better. (Or it might. One way to tell...)
We're not talking about collecting bottle caps. We are talking about capital outlays. And we're also talking about the value of not getting scammed and the value of ignoring fools (I am most definitely not calling you such). I have better things to do than delude myself that the "advanced cable geometry" of the 6 foot, $5,000 Hahathanksforthebucks Magnum Onan speaker cables "lifts veils" and delivers a "by no means subtle" improvement in sound when a) I know that's bullshit and b) yeah, I
do have more important things to do with my $5K than get ripped off.
I'm sorry, but sharing subjective impressions may be slightly entertaining, but it means fuck-all. At my age, I have better things to do with my time.
