What is wrong with op-amps?

Also, I have dialed in distortion on one of those things myself and listened to the difference. For some source material a little distortion sometimes sounds better. You can say its only a legend all you want, but that doesn't make it so. I guess we will just have to disagree on this one.

No, I won't say. 🙂
I know the difference between modifying of a single voice versus an orchestra recorded with nice reverberation 😀

The legend is when people move some phenomena out of contest and expect it to be true. 😛
 
In case you get the urge to think: how much time does the feedback signal take from the deviation of your bicycle from straight path, to your eyes, to your brain processing, generating a control signal, send it to your hands/arms to do the correction, and you never (almost never) fall down? Isn't feedback wonderful . 😀

Jan, you've neglected one thing in this analogy... it works WAY better if the bicycle is moving!

When the bicycle is moving the "falling" is always behind you...
...so try the balance thing with the bike standing still? Not so easy, although some may be able to do it, but usually not with the wheels straight ahead...

(actually the gyroscopic forces help keep you up)

_-_-
 
Feedback reduces distortion, except in this thread.

So, op-amps do have more than one downside after all.

1 - They are painful when stood on.
2 - They are painful when sat on.

This thread turned out to be quite a revelation after all then eh 🙄

Except for one minor detail.

It reduces distortion but also shifts/add distortion products elsewhere in the spectrum, albeit at reduced levels compared to the best case no feedback or less feedback. The argument revolves mostly around IF these changes are audible and/or objectionable.

Still no free lunch.

You're so wrong on so many levels that it's not even funny. Have you ever wondered why people need to "learn driving a bicycle" before they can actually drive one confidently? What that "learning" process actually does to the brain? And why based on feedback alone (with no prior learning) they tend to fall?

Nothing is wrong.
Learning to drive is constructing of nested feedback loops.
