So what is deep negative feedback and how is it influencing sound?

[DNCAgain]

Thrust, eh?
hmm...
units of thrust (force): Newtons (N): One N = 1 (kg)(m)/sec^2
power = force x velocity
I mean, I guess amplifiers could be spec'd based on thrust...
My brain hurts.

Sorry for misunderstanding. "thrust" is a common term we use in our language to describe power

Ok you bottom-quoted my post, but unless I missed a post somewhere I've still no idea who 'he' is, or what the material is that you refer to.

it's a vlogger on a video platform of my country

Maybe it's about this amp:

GaN Systems and Axign Demonstrate New 500W Class-D Reference Audio Amplifier

GaN Systems, the leading GaN power semiconductor specialist and audio technology innovator Axign, debuted a new groundbreaking GaN-based 500W Class-D audio amplifier. This reference design merges best-in-class technologies, including GaN Systems’ GaN power transistors and Axign’s Class-D...

Which is certainly not feedback-free!

Sorry I can't have access to the website. but I'm sure that it is not the one I mentioned because I was talking about a product of a very small company in my country.

Thanks for the clarification. The vagaries of language.

I'll just pop this here;

Distortion and Feedback

Distortion and feedback - is feedback as bad as some people claim?

You did not state what you claim to have stated. I quoted directly a false statement you made. Nowhere in your post did it cite “sufficiently requisite” feedback

#Sigh Read my original post #35 where I stated:

"However, the control system needs to have the same level of requisite complexity as the system it controls."

You are failing to demonstrate that you understand these "Baxandall" distortion curves show and why they are not in scope with my original post 35. You reference Bruno Putzeys, but have you read what he clearly says about the curves.

Below is the opening post. The "he" is most probably the someone that has a website on the net.

Yes, you quoting it again adds absolutely no specificity.

Nor does this. A bizarre bit of obfuscation.

I think what Mr. Pass is saying, however, is if you have real devices with nonlinear gain curves (which includes all devices used for amplifiers), its better to trade for lower order harmonics than higher order

Why trade anything when you can make all the distortion below audible?

Brought to you by the people who used feet to measure length

Past tense?

Past tense?

... they have measured height in hands, too (present perfect tense).

The 17" rack standard would be better if we called it the cubit rack.

Brit-Fi vendors of a certain more trad style could sell their best finished fathom speaker cable.

A "smearing of details" would be shown in a frequency response graph, since those details have to happen as frequencies we hear.
