How do you know your impressions are representative of the whole recording world? Seems like a bold statement to make.

But I get why you stick to the narrative of some people being able to trust their ears while others can't. Superiority sure feels great, even if it's a product of your imagination.
 
On the subject of marketing ploys, I often wonder who stands to make more money.... the feller in the business of telling everyone that sq has peaked and the cheapest parts/manufacturing is good enough(So you might as well save money), or the little guy selling high quality, precision parts with custom manufacturing that cost more(which for arguments sake may or may not sound better.....we’lll leave that to the individual who buys it)
Certainly makes one go hmmmm.;)

The whole "who is profiting" line of thinking is an utter waste of time and a litany of logical fallacies. I wish this garbage argument would fall away so more meaningful conversation could go on.

As a quick reminder, even people with integrity need to sell their product (whether material or an idea or ...). If whatever someone is selling smells funny, there's inevitably a trail that follows. And some times what smells funny is our own ignorance. Pretty important to tell the two apart.
 
Mixing of two tones results in super- and subsonic products. Say 2kHz and 3kHz yields a sub of 1kHz and a super of 6kHz (and more harmonics). These can happen mid air and also with headphones mid brain. One key of a grand piano has three strings, all slightly apart, making a 'single' tone in our hearing. Could one hear a subsonic tone of 1kHz if two tones of 30kHz and 31kHz are produced at 'loud enough' spl?

Your confusing multiply 2 signals with adding them. Mixing audio is adding the 2 signals together. This does not create any new freqs. 2khz plus 3khz is still only that. Multiplying 2 signals is amplitude modulation (as in AM radio) and that creates new frequencys and this does not happen with sound in air.

The problem is that for every second guy theres 20 third guys pretending to be second guys selling lies (snake oil) at outrages markups. Thats who makes the most money. And thats why theres so many of them.

You're right on that one, but our brains does not operate as analytical lock-in amplifiers. The twe sugarcube-sized human hearing devices sends a repetative puls train to our brains when nothing is detected, and an extreme complex modulation of pulses when something is detected. This modulation is interpreted in a fashion according to 'nature and nurture' and differs for every individual person. The dynamic range of the mechanics is some 20dB, and how louder sounds are processed is still a mistery (afaik). It is plausable that this extra dynamic range is also part of the modulation of the pulse train. We are not capable of hearing an absolute reference.
 
The ear has about 60db range, but its a movable limit which slides up and down as required. The lower limit is the volume level of blood pumping in your brain, the upper limit when your eardrums blow. I think thats about 10db to 150db.

Of course you can only hear within the 60db range at any point and its always constrained by the upper bound ie the loudest sound.

There's great involuntary stuff in there like the ears physical response to loud transients where everything tightens up to reduce perceived level. Certain people can activate this response voluntarily by tensing muscles above the jaw, it sounds like a dull thud.
