Those are from Victor Schauberger, Home | Schauberger You can spend all day reading crackpot science if you want. I wonder why so much of it filters down to audio more than other hobbies.
Yes Ed I put a foil hat on every time I use my cell phone.
ScottJ - Excellent link I knew if I read far enough a Nazi conspiracy would show up. I also have to check the Tibetan singing bowl I chose out of the pile at the store.

What happened to the Tibet religious scrolls after the Chinese got thru with Tibet and installed their own govern? We were told they were all burned. Thats the official story. But were they?

I don't understand. (Is-it misunderstanding day, today ?)
Mercury is a conductor (something else to be expected, like some semiconductor jonction effects, or micro movement of it with signals because it is liquid state ?). A conductor can have a certain impedance curve, that can vary with some external factors (temperature, sizes, magnetic fields etc. etc.).
What could produce a "dominant sounding" from the material itself that we cannot measure ?
(We understand the limitations of electro chemical condensers and we know why.)
J.C. did not said it was bad sounding, I could dream of something that can bring "good sounding" to any source ;-) Not Hifi, but better/worse pleasure.
"intriguing/interesting", indeed.

For who ?
You said: "1 uV of distortion if the coil is feed from perfect DC. Tested at a signal level of 10mV".
According to the fact that 1mv is 1000µv, it makes 10mv= 10 000µv.
1/10 000 = 0.0001. X100 (because %, as you wrote) = 0.01 ... what I wrote.
(I am a little drunk, out of a lunch with friends, but it seems correct while I was never so good on calculations at school ;-)
I thought inebriation was supposed to lessen the effects of distortion, not increase them??

Max is really "out to lunch" today! "avoir une araigneé au plafond" is the best I can do. I used to be fluent and "street-wise" in French - at least Parisian - some 30 years ago but the subtilities are fading fast!
Hi T, what are these properties of impedance and resistance actually ?......on first overview resistance is transduction/conversion of Electro Motive 'energy' (which itself is a conversion of Electro Potential 'energy') to other manifestations including Electro Magnetic Radiated energy in the form of infrared light which we typically regard as losses in electrical systems, but is infrared band EMR the only energy conversion product of resistance transduction ?. My investigations say that the presence of non magnetic forms surrounding or in proximity of system conductors and transducers (magnetic or electric) will cause change in nature of system noise floor.
The answer will be buried somewhere deep in atomic theory, or perhaps in Maxwell's full equations, the answer is or will be somewhere. The influence of particular materials/compounds is on spectrum and dynamics of system noise floor, and according to particular material/compound can be "dominant sounding" (and identifiable). Amplitude and dynamic characteristics of the system noise floor is in large part what gives 'voicing' or 'house sound' and we have all historically experienced identifiable house sounds from the major (mostly asian) domestic audio manufacturers....look closely and the common factors and also the differences of such equipment are laid bare to the eyes (and to the ears).
I have mentioned M-Noise several times now and no response to this most useful test signal which neatly triggers excess noise behaviours,.... 'perles avant porc' ?. Comparison of before and after recordings of changed system using M-Noise signal discriminates this difference and the changed loopback recording can also be described as being 'remastered'. What is 2ch remastering as we know it ?......sure, it is replaying of old tapes (or digital original) and transmission through typically analog EQ, Comp/Limiting etc processing which is applied according to SE ears taste/marketing dept goals etc but that is not all that happens.
So, the original audio signal has been deliberately freq/amplitude/time altered, but at the same time the noise floor of the signal is (accidentally) altered and according to the analog equipments self noise characteristics, which includes steady state and dynamic behaviours. There is SE preference for particular outboard processors and it can also be practice that a particular processor is included in the signal chain but in bypass mode for purpose of adding a 'something' or better 'glueing' of the mix.....this is choosing noise floor 'flavour' and I am sure you have done this in your career even if unconsciously.
I am certain that JC and his co did not prefer the sound of mercury relays, hence the rejection of this switching. I expect that the sound was 'drive you out of the room' bad and unlistenable long term.

432Hz is a subject in itself, thanks for a couple of links in that page and the history lesson.
They mean biological response to frequencies, not the term FR as we use it.
I read somewhere once that astronauts require artificially generated Schumann field for long term living in space/orbit.....can anybody confirm this ?.

Ha, I'm perfectly straight, it might be that T and others are not lol, good on them and why not.
Grasshopper, the bat by the height of his position in the tower and by the response of his eyes is able to see things of the greater world that you are unable to see or even imagine for the term of your life inside the locked and shuttered classroom.

I fully agree, of course. But, let clarify my positions.
I do not agree with so called "objectivists" of this forum, that believe everything is said by measurements and are strangely suspicious about "listening".
They presuppose that we are all stupid puppets, manipulated by evil salesmen of snake oil, hypnotized by their marketing pitch. I was shocked to read Mola-Mola's gibberish on their web page. Gourou Bruno P. ;-) being supposed to be more serious than that. Specially about its Class D amp, that are far to be the best amplifier that we can find on the market for the money, without wishing to be disagreeable !
On the other hand, I claim that if we do not know how to measure everything we hear, if we have few ideas about our audibility thresholds, which, by the way, vary significantly from an individual to another, according to our listening culture, the capabilities of our measuring devices are now far beyond those of our senses.
So, in terms of relay, if the background noise of these mercure relays is well below that of the other components of our system, if the distortion is of the same order, I consider this subject as settled, unless listening (which I did not do on mercury relay) convinces me otherwise. In this situation, it seems reasonable to doubt any serious change in our listening impressions can occurs: Il will work on an other more important defect first.
Let's take an example. At the beginning of my carrer, in the years 70, we were using carbon layer resistors in the R&D department of the company I was working for. I found a big difference, trying metallic layers ones that were expensive at this time: The sound was more fluid and less "granular". Trying to find an explanation, I measured a huge improvement in signal noise ratio when comparing the same amp after exchanging all the resistance where it was important. Now, i take the greatest care of the quality of the feedback resistance (and all others in the signal path.)
Same thing about electrolytic caps: Noise, impedance curve and distortions differences are measurable.
