It won't work, imho. Most customers don't have good ears and it is better to tell them that the product is very good by showing numbers and saying good things about the product to make them feel it is worth their money.
Additionally you can design amplifiers that focus on things that is easy to perceive and is preferred by the majority, such as subjectively better bass, better sonic, probably better vocal (tho this one is difficult unless you allow for high 2nd harmonics).
If artefacts of any kind (prat, soundstage, grainy sound, frequency deviations, anything you can think of) are audible, then properly conducted double blind listening tests can show this.
And we can correlate this phenomenon through properly conducted listening test with objective measurements. 😱
Can it explain how and why some people can't perceive stereo imagery, is it because they have superior perception?
And we can spend some time in the fora to find the exact words that make that correlation eligible to be documented. See you in 2100 to see if things had changed. I doubt 😱
Not for now.
But in the future yes.
Will all people be honest enough to realize that they can fool themselves?
How far do you know that some people with good perception ability cannot perceive stereo imagery? Because it is highly affected by the speaker design.
I'm honest, so I will post this:
I think many of my knowledge about perception is built with experience, more often without any kind of controlled validation. Of course, some ABX result increased my level of confident but normally I don't have time and patience to set up such objective test.
When we hear or compare something, there is no way we can be free of bias, even by thinking that there is no difference. With time we will repeat the same experience again and again and our level of confident is increasing when there is consistency in the result. A good track record of being always proven right also increases my confident to trust my ears' sensitivity.
For example, lately I replaced a cheap resistor (my favorite cheap resistor) with a resistor 5x the price. I was surprised by my perception of the sound. Of course, there is no evident that I can objectively draw a conclusion that the resistor was worse than the other equivalent Vishay brands. But I trust my sense more than the logic, such that until proven otherwise, or I have something to loose, I will not purchase that resistor again. Even tho I rather believe that ABX test will show that I cannot hear any difference.
The resistor is good from looking at the spec. Too good to be true I thought. So I tend to think that it is a 'FAKE' resistor. It was sold as Vishay-Draloric SMA0207 anyway.
I don't, but it would be a logical assumption for them to perceive two separate sound sources when others don't would indicate superior perception would it not?
analog_sa,
OK. In that case, the most important criterion of healthy harmonic generation is met, although the present discussion suggests that bad sound is a symptom of mental illness.

Yes, I think so if it is the same system/speaker. But I think superior ears should be able to hear 'both'. He will understand what the others hear but he just can hear/see deeper/more.
What I'm getting at is that the stereo illusion may arise from a flaw in perception and hence the whole notion of superior perception being somehow better may itself be flawed.
If using stereogram as example, I can see clearly both the reality and the illusion. The illusion is not a flaw, it can be explained with Physics. The keyword is 'seeing more'.
With audio, more than 80% of my listening is with mono. I don't see stereo or imaging as an important quality aspect. Actually, it is not one of the quality aspects i usually try to improve. I have no minimum requirement (threshold) for sound stage, depth, etc. It doesn't mean that my stuff will be inferior in that department though.
Only if you know what you are testing.
Double blind testing is bias free. It's used in every field of science for this reason.
Only if you get positive result. And you don't get positive result in an instant.
