If you read my post, you would have noticed that I was referring to the output impedance of the mic preamp. I didn't mention its input impedance because it is irrelevant in the discussion.
And that's exactly what I discussed.
With all respect due to Ing. Wuttke, I didn't learn anyhing from his document. It is a vulgarization, destined to technically untrained public. It's electronics #101.
It is your opinion.
Unfortunately, the connection to the output impedance was not so clear in your post.
What's not clear in this :"In practice, the optimum depends on the relative value of the microphone and preamp output impedance."
The input impedance of the mic preamp would be relevant only if it was unduly low. It is understood that the mic pre input impedance is about 5-10x the mic impedance.
Which, fortunately, is not my case.
Who is the intended audience for the paper?
I value Abbey's opinions very highly.
As I noted, I mean no disrespect to Ing. Wuttke, on the contrary, but the book is not of a very high technical level.
Nobody said that "all cables are the same", but as can be noted in Ing. Wuttke's book, the dominant electrical performance parameters are very few, predominantly capacitance and shield coverage.
This is the introduction to the book.
Ahh right. Yes. Understood!
I doubt it... he keeps pretty busy as a moderator here (he's the nice one).

For it, it would also take some source of energy. What would it be?
Can you describe these "capacitive, inductive and resistive factors acting from the outside"?
Passive pick-ups built in guitars have low level of power, hence need care for being transmitted properly, but it actually works in millions of parts of the world.
There is no doubt that keeping cables short, in all circumstances, from ECG, ro nuclear plants is good for the efficiency of power transmission.
Neither do I know you.
Do I need to have a website to exist?
