As usual, not very helpful, Edmond. And PMA, I am not your critic, you should know better than that.
No, you are just being 'nasty', and attempting to obscure the direction that I am trying to go in.
Nasty?! 
As for my post 19255, I was serious. I hope you will serious as well on that matter.

If it weren't OT, I'd ask for a definition of nastiness. 🙂
Have a little pity on us mortal mods. This thread became one of the biggest of the forum and splitting of posts isn't something we do for fun.
So, where were we?

Let me be clear: Edmond is LEADING WITH A CONCLUSION, in other words, that he has already made up his mind about feedback and its relation to open loop linearity, and is not interested in going further.
PMA is 'advertising', something that I am inclined to do as well, in showing that he, too, does a good job with open loop linearity.
I am thinking about typical audio IC op amps that are used by the vast majority of manufacturers, in most of the audio equipment that you and I use for practical reasons. For example, why does SONY use a 4558 rather than a AD797? Cost, cost, cost! Rationalized by Edmond, as being 'good enough'. Now do you want to go forward, or just 'dog paddle' where you are?

linearizing.....
Sorry John, but now you are talking through your hat. This is plain BS!
edit: Did you ever have a look at my designs? Probably never, otherwise you would know better.

'Nasty' was too strong a word, but I could not find a better one. Yes, I am just 'BS'ing' as usual.
Of course, accusing me of BS'ing is not 'nasty', but what would YOU call it? Moderator, please give me a word, and I will use it.

Tip: Over the years I learned not to respond to antagonizing posts. Works wonders and makes life very easy. 🙂
I'm sorry, Netlist, but it just won't work in this case. They just ask the 'question' or 'statement', over and over. I often try to politely ignore people, but they almost invariably stand in my way, and insist that I answer them. Then, they are not often satisfied with my first response, so I get more specific, and then either I am 'BS'ing' or compromising them, and then they yell for their friends. It gets old.
Interestingly enough, I found an input on TAN, a phone network from 1996, 13 years ago, where almost EXACTLY the same questions were addressed at a AES convention, as discussed here last week. The similarity was remarkable! It just shows that I am going in circles addressing everyones' opinions. I don't have enough time left to do this for another 13 years.

Let’s try to make a conclusion here;
An open loop linear transfer function is important, even if you like to use NFB.
John, do you agree?
Edmond, do you agree?
BTW John who are “they”?

Obstruction !!!!
John, weren't we talking about linearizing the open loop thingy, instead of 20 years ago I did this and 30 years ago I did that, etc.?

Hi Stinius,
Of course I do agree. Wasn't that clear right from the beginning?
Cheers,
Edmond.
