And it seems that the more you violate them the worse/less convincing the equipment sounds.
The use of odd ordered harmonics to determine loudness is the tip of the iceberg, but in itself is extremely inconvenient for the industry: loop feedback tends to exacerbate odd ordered distortion.
I am of the opinion that if you can measure it and hear it, then is real. The flip side of that is if you can measure it but it does not seem to make any audible difference, then its probably not important. Finally, sometimes a spec looks good but is counterintuitive or doesn't help; THD is an example.
Now human hearing rules are universal with all humans. They transcend taste. OTOH our current measuring system is based on making the product look good on paper. That's good for sales (initially) but is the Emperor's New Clothes when it comes to the human ear. That's why the spec sheet is still not all that useful after 50 years. I maintain that our ears are the most important audio asset we have; certainly the gear should serve our ears not fight them.
My point is that we don't have to work in the dark- these hearing rules are being figured out all the time (and some of them have been known and ignored for decades). It does not matter if you do measurements or disdain them, in the absence of knowing how the ear/brain systems work, failure is going to be on the horizon, unless you can ram it through with enough marketing. We've seen that before in spades. That is why LPs are still here, 30 years(!) after the introduction of the CD, why tubes are still here 55 years(!!) after the introduction of the transistor, and why we still have these 'discussions'; the new technologies have been stellar at being unable to supplant the prior art. But if you follow the dollars, you start to see why this happens.
I think there are certain subjective listening habits that do work; here's one:
a change is proposed. 5-8 musical selections are chosen that test the parameters of musical playback: bass impact, depth, soundstage width, detail, harshness/smoothness, etc.
They are played in order, the change is made (and only one change), and then the same selections are played *in reverse order*. The best efforts are made to insure the volume level, seating and the like are maintained.
I don't usually even start unless I can get good sine wave analysis on the bench though :)
