A spectrum of electro-mechanical, electro-acoustical transducer is very different from that of a strong FB suppressed distortion (low order reduced and grass of high orders appears), and it is evaluated by ears and brains, not THD+N meter.

Must respectfully disagree. I am the one who repeatedly posted information about perception, the brain processes that ultimately make you aware of a sound picked up by your ears, and how that is integrated with many other sensory and non-sensory inputs.
John has not explained anything on that matter except often implying that those of us that disagree with him are either deaf or prejudiced.
You may want to review your reading.

As a professional metallurgist, I can state pretty categorically it isn't annealing, unless your running enough current to heat it at least 60°C or so above ambient, where solid state diffusion in pure silver is at least theoretically possible, albeit slow on the order of the geologic time scale.
A much more likely possibility is the formation of a VERY thin layer of metastable silver oxysulfides, which curiously exhibits semiconductor properties. It has been theorized that this layer could have some interesting quantum effects realated to the depth of the skin effect that occurs with high frequency signals. However, to my knowledge there has been no practical experimentation to confirm or contradict this.
The geek in me couldn't resist talking about something I actually know something about

These spectrum's don't look too good to me

Any ideas how to eradicate or reduce it ??

Loudspeakers designers are the ones to deal with loudspeakers distortion, while audio designers are the ones to deal with distortion in audio gear.
Anyhow, you seem to argue some of John Curl statements, in the guise of innocent questions. It is perfectly okay to argue anything and everything, it is the guise which I happen to dislike. To my view, better say whatever in your mind right out.

What formal qualification makes one a successful audio designer?
What formal qualification is needed to appreciate good sounding audio gear?

I thought audio design encompassed all things audio which includes loudspeakers.
I didn't understand your second statement.

AFAIK, most loudspeaker designers don't design amplifiers and vice versa.
Indeed, amplifier designers should take into account the way loudspeakers behave, not only its distortion, which is why listening tests are indispensable.

It doesn't guarantee success nor is is it a requisite to use and enjoy audio equipment but does provide a better understanding of the issues and devices involved and avoids you getting caught up in things which don't really make a lot of difference like bits of wire 😉

And loudspeaker designers should take into account the way amplifier behave (and their limitations) instead of manufacturing so called 'high end' tooters with impedance dips of 0.3Ohm and bellow.

To my ears, there are differences between different wires and cables.

What does that prove?
That they are different?

Was that evaluated in a double blind environment or were you well aware of what you were listening to ?

Blind tests, which I specified earlier in this thread. I didn't know which cable I heard at any given time. I even didn't know if it was switched to the same cable, or to a different one.

It seems that different people specializes in different areas. It takes years of learning and experience to specialize and to excel in any given area.
Re: Re: Re: Re: ... turkey for dinner?
On an average system it is a waste of time to worry about "things
which don't really make a lot of difference" but on a SOTA system (which this thread is about) everything became important, you will be surprised to hear what influence "bits of wire" can have.
