What is wrong with op-amps?

A good result is not when mixing clipped signals to clean ones, but when a crest factor is being decreased by a soft clipping limiter. The record becomes "louder", less chance to damage it by dirty clipping amps.
No magic here. I've experimented with it a lot, and found that nobody likes added distortions, no matter what claims, rather presence of one distortions (less audible) versus presence of other distortions (nasty sounding) is being preferred by people. However, some "audiophiles" adhere to a "Cargo Cult" and believe that "a signature" is what is needed by "Real Audiophiles".

How about it's just a naming issue. By "signature" they mean "we preffer this way of doing things". As compared to the more unpleasant one. Just what you described, but in different words.
 
Speaking of an expectation bias... ;-)

If you connect all bases together, no bias, to the input of your opamp, there should be huge nasty crossover distortions, right?

Not necessary... Add a resistor (something like 47 Ohm) between bases and emitters and listen... And compare... 😀

Sometimes it is better to discard odd entities, searching for Graal. 🙄

Very effective (plus cost and space saving)

Thank you Wavebourn 🙂

At this point I should mention the MAGAMP or magnetic amplifier, this is a transformer based OPAMP. The drift is poor and gain not really too adjustable and the frequency response (depending on excitation frequency) really a few Hz, but it filled a requirement in it's time.

A steel mill in Rotherham was still using them to alter the field (I think) on motor-generator sets for DC motor speed control until very recently. Last 5 years or so.

Control of the Primary Mill manipulator sets was described as like "two majestic galleons on a heavy sea". Not close control 😀

With 6" of backlash in the gearboxes and tossing 20T hot slabs around, it didn't really matter. Delay on the joysticks meant you had to be on the ball when bringing them together. Overshoot and delay with 2,000HP and a lot of inertia meant a big clang despite sticks full apart!

I don't think they are "saturating transformers' as described above for audio, but the principle sounds similar and they might be with a higher excitation frequency. More info please!
 
I don't see what the issue is with this, tbh. No magical violations of physics or needing superhuman hearing ability. Preferences can be what they may!

If there is a problem, it most likely arises with another aspect of human nature, which is a tendency to automatically attribute cause and effect. If one system apparently sounds "better" than another, it may be incorrectly attributed to it being more accurate or more realistic. It is probably audiophiles, in an attempt to explain their equipment choices, who naturally feel a compulsion to construct what may be seen by others as scientifically implausible explanations of cause and effect as to the how and why of their preferred equipment's superiority. It's, in part, a way of justifying to themselves and to others (in a way plausible to them) the seemingly good reasons for their choices.
