Transformer distortion (THD)

???
The contents are important.
It is evident that the numbers are different form 20 years ago but the quality of the technical articles are the same.
A lot of arguments were involved.
Fabrizio developped the sw for loudspeaker that is one of the best available in the world. (unfortunately it is only in italian)
Every time there is a stuff with interesting solution there is a explanation of the circuit with relatives test.
You don't know anything about the story of Audio and you are asking the numbers of copy?
It is a joke?
Before wrote sentences, study.

Ciao
Walter, the figures, please. More difficult: 1) how many copies they print, 2) how many copies they sell.
 
First, we are speaking about OT and you are asking the number of copy?
Please, study the history of Audio that it now is at number 444.
Go to the internet site and you can see the list of arguments, some of them are available for dowload so you can learn a lot of things
Some example
https://www.audioreview.it/tecnica/articoli
https://www.audioreview.it/tecnica/approfondimenti
and in case give me your name and email so I can ask directly to director Mauro Neri that can answer to you.
I haven't these details.

Walter, it is a magazine. A publication to entertain people. Nothing more.
 
And this what's it means?
Put the hand in the pocket and spend few euros.
At the end of the story it seems that you are looking for the best so the economical aspect is not a problem.
I suppose.
And, probably, you learn something new interesting things.
I know a lot of people that wind the transoflrmer; in some cases are a good product.
In some cases.
Most of them haven't the idea that a minimum of tests are helpful.
In many years I have seen ( and tested) a lot of homemade transformer in every body and aspect.
Honestly I remember just few.
And this not because the people didn't put the enthusiasm but just only because they didn't test them properly to check where are the limit.
In attach the machine of FIAt tha comes from Da Vinci brand ( now dismissed)
It is beautiful and, due the fact that I am not smart to use it, Massimo ( help me) is the master.
One of the best mavìchine available; not last geneartion but efficent

Music and Magazines are good things.

You either support the musicians, music companies, authors, and publishers; or you do not.
When the copyrights are still in force, obey the copyrights.
Or go to the trouble to get permission to copy.

How often did You work for free?
No, I do not mean for a charity, etc.

Just my opinion

The post nr. 130 gives you an idea of the quality of certain people.
I have all the articles ( mine and others) but I haven't the authority to give some of them to others this because are published on a magazine.
I can share some photos but that's all.
Then the funny thing is the approach, ridiculus.
For some few euros.

I don't know about that. The market dictates the value and price. We have in my country a "simular" magazine and in France there is "Maison de L' audiophile". Both are free now. I can also read many articles from "Sound Practice" and "Glass Audio"
Because it's in Italian i think the value. of older articles, is about zero.

He, it's not a book, movie or music, that has much more influence on people, this is a niche market

Are you French? "La Maison de L'Audiophile" was the shop, in Paris. Do you mean the "L'Audiophile", it was the rewiev.
