As with the $7900 stealth amp I have , and other "high end" equipment , perceived value is a major factor. While one can see much higher grade components in such equipment and a certain degree of superior engineering (it must sound better than consumer "mid-fi"), a proportional level of "hype" , fancy jargon and photographs often accompanies the product. So the price reflects the increased marketing required to "loosen" the change from a targeted group.

You forgot about conditions when they wouldn't be heard: when they rise below 0.5% on the loudness above certain level. If they rise with lowering of loudness they are heard very well.Joshua_G said:
Never heard it put like that . 😕 Looks perfect on simulation and CRO , but I still do not like it's sound ? Sounds subjective ... but audio's final factor is very subjective (our brains).

Sound distortions are aberrations of sound that are perceived as audible differences between captured and reproduced sounds

I am absolutely serious. However, I have to add that hallucinations are not necessary symptoms of mental disorders. Example: stereo images.

Then take the difference between the input and output signals and study the remaining artifacts. If there are none and you still think that it is not doing a good job then you need to book yourself in to the nearest shrink 😉

This is totally wrong (and I am dead serious). Perfect accuracy is not necessary pleasant, its the less damage that an audio system can do. If one does not like the sound of accuracy, then he should look after a less accurate system that would make him happy. At the same time though, he should refrain in extrapolating his preferences, understanding that he's after his own private Nirvana.
There's nothing wrong in one appreciating the warm sound of 10% 2nd harmonic distortions but its wrong to state that is the best sound since sliced bread.
It is not about audibility of -140dB at sine. These high order harmonics are an indicator of poor circuit, poor sound. I wanted to evaluate one circuit recently, but simulation showed constant grass of high order harmonics between -120 and -140dB, so I gave up a prototype. It would be a wasting of time only.
Yes , one can do that into a static load , confirm acceptable levels of near perfection and be happy with our statistics. 😎 When you then drive the loudspeaker , and the same sound is expected (according to FFT's and THD) , you DO think you need a shrink.
I really did think the above quote was true initially ,but audible differences do exist between different topologies and even different semi's. There would be no market for class A or tubes if just THD perfection was the only factor.

Don't forget that the answer will be, "because they love specific class A or tube distortions" 😎

I think the current popular criticism of overly accurate signal chains is that, "they just don't get your toes tapping".

I never saw an overly accurate signal chain, Scott. I mean, from an air movements in front of microphones to air movements after speakers. In any case aberrations exist. But in some cases you can abstract from aberrations and imagine that the equipment does not exist, in other cases you can't no matter how hard you try to convince yourself that "the chain is an overly accurate".
