Mass-free screen
Bad hearing due to shielding on ground
As we know from Prof. Dr. Magda Havas 's Dirty Power research, even harmonics of less than 5 millivolts can exceed the maximum recommended level of 50 GS units for electrosmog exposure in living spaces, depending on the frequency. This means that even very low levels of interference on the ground will negatively affect the human nervous system and thus significantly impair the musical experience. Therefore, it is absolutely essential to prevent the ground from radiating interference – i.e., from acting as an antenna.
High tension on the ground
As can be seen from the two oscillograms above, if the mains plug is inserted incorrectly, the voltage on the ground can clearly exceed 100 volts. Even when the mains plug is turned correctly, over 100 volts can occur - here approx. 45 volts. But we don't know how strong the harmonics are that are particularly critical, i.e. those above 2kHz.
Any music lover knows that reducing this interference improves the sound, as he phases out his hi-fi system when it is set up - i.e. tests the correct direction of the power plug.
Dirty power measurement on the ground
It can be seen in the upper measurement that interference can be found on the ground in the entire spectrum from 2kHz to 1000kHz.
In order to test the effects of the radiation of the mass, we “cleaned” the mass with a special circuit, see measurements below. The hearing test showed significant changes in the sound without anything having changed in the signal.
The radiation of the ground disturbance through the screen
The question is, what function does the screen have to degrade the sound? The answer is that the screen is an antenna for interference.
For a test we assembled a coaxial cinch cable once with the ground outwards (normal) and once with the ground inwards (inverse). The cable parameters and thus the electroacoustic oscillating circuit with all its frequency and phase influencing parameters were the same.
It was noticeable that in the blind test all people clearly preferred the cable with the mass inside! This is also confirmed by the field measurements. The cable with the ground inside clearly has the lower field radiation (see below).
In hi-fi, phase correction is a standard optimization. All medical studies on Magda Havas 's Dirty Power show an influence on the nervous system and thus on hearing.
All of our measurements on the ground show the same problems that were raised by Magda Haves. All hearing tests with manipulations on the ground and the radiation to the outside show that there is a considerable sound problem here.
The innovation in HiFi - the massless one VORTEX HIFI Nano Shield umbrella
Vortex HiFi uses exclusively groundless shielding technology. This allows you to protect yourself from ground loop interference in devices with open inputs and outputs using Vortex HiFi Nano Shield Plugs . Potential equalization can also be perfectly achieved via Vortex HiFi Nano Shield cables , which are shielded to ground potential.
This field sink around the Vortex cables prevents interference from being radiated from the ground source. Vortex HiFi cables can be used as universal cables for digital, video, signal, and equipotential bonding, and this is without ground interference, as even the connectors are shielded with the ground-free Nano Shield technology.
I don't know what to make of all of this. I am an electronics specialist and I am very familiar with hi-fi.
But I find it difficult to cope with the crowd inside and the signal outside.
I suspect this could be charlatanism with the aim of getting people's money out of their pockets.
Dear Mr. Gottfried Karenovics, dear readers
Thanks for your comment. This comment shows 4 facts as an example:
1. Many people are stuck in old ways of thinking. They operate on the principle of " That's how we've always done it." And if someone does it differently, they're either stupid or trying to pull the wool over others' eyes. However, the field measurements taken around the coaxial cable on this page clearly demonstrate the advantage of placing the ground on the inside. This reduces the radiated field strength. The text also clearly explains why we do this. We want to protect people from ground loop interference – that is, reduce the field strength. Therefore, it is completely beyond question, and has been proven by measurements, that the approach we are taking with the rotated ground is the right one for our objective.
2. The self-proclaimed "experts" don't actually argue their points. They only make judgments, and they do so based on a foundation that isn't transparent to others. But since they're supposedly "experts," it must be true! Why our inverted coaxial cable is exactly the wrong choice for the specific application and objective we're describing is something the "expert" remains silent about. This is because these so-called "experts" don't engage with the objectives and often only know that " THAT'S NOT HOW IT'S DONE ." Why it's supposed to be wrong in this case is something these self-proclaimed "experts" don't understand at all. Otherwise, they would enlighten us all, and the person being criticized could address the issue directly. But since these people have no clue about the specific problem, nothing concrete comes of it. They might embarrass themselves. If you don't say anything, you can't say anything wrong.
3. Many so-called “electronics specialists”, especially in the hi-fi sector, have a huge problem with adopting a point of view other than a technical one. A technical solution in HiFi has a signal problem to solve - period! For these experts, it does not matter at all how small the signal error is compared to the total error in the transmission chain. Except that a signal error counts!
Here is a cable example: If a loudspeaker produces a 140 ° phase error at 20.000 Hz, but different cables can only change the phase by 20.000 ° at 4 Hz, “HiFi specialists” have long discussed how to improve this tiny phase error by 2-3 ° and they see it still considered extremely important. How absurd this is becomes clear when you know that the wavelength of sound at 20.000 Hz and 343m / sec speed of sound is 1,7cm. 1 ° then corresponds to a distance of 0,05mm! You read that right 0,05mm. Even different postures when listening to music generate changes in the relative phase through a multi-way loudspeaker by a multiple of the signal error that is caused by each cable! Nevertheless, we hear significant cable differences! The errors in the amplitude frequency response are even more blatant if you compare cable errors and turning your head when listening to music. According to our own measurements of head-related transfer functions (HRTFs) using a dummy head, the frequency response errors are basically never (2-channel consideration) below 15 dB. While cable faults make up tiny fractions of 1dB in the audio sector. The signal-related perspective makes no sense in practice with cables.
Despite these clear facts, people who go other ways and pursue other goals, namely to achieve an optimal music experience by reducing electrosmog, are vilified. We present tons of facts, such as medical examinations, HRV EKGs and technical measurements that can be traced at any time - as here on coaxial cables - which underpin our point of view.
For real professionals it would be easy to understand our measurements. On the basis of these concrete facts, one could then start a discussion, at the end of which one would then make an assessment. So do it real Professionals. But for these self-proclaimed "electronics specialists who are very familiar with HiFi" it does not matter how many metrological and medical facts are listed. These are simply ignored - because they do not fit into your worldview.
4. On the Internet, many think you can simply insult and denigrate people. Mr. Gottfried Karenovics puts forward without any single argument and to go into the facts listed in the room that we are charlatans who want to pull people's money out of their pockets.
We are a small company that uses a huge amount of our funds to research fundamental relationships. I claim that with over 50% of our funds that we spend on research and development, we are at the top in the hi-fi sector. Our share of the costs for advertising is less than 1%! We don't have to sell our products like warm beer with pseudo price discounts and huge advertising expenses. Our dealers are convinced by conviction! Many of them are musicians themselves and also engineers. One is even a metal instrument maker and he was a professional musician.
Why are you denigrating us, Mr. Karenovics? I have 2 children at school and my co-worker had his third child a few days ago. What makes you want to harm people you don't know? Before denigrating people, think about the fact that there are real people on the other end who can harm you personally.
With kind regards,
Norbert Maurer
