Well it doesn’t say that on WBF, just that it’s not 1+1 - but that is one single user posting which is from Steve who is overly enthusiastic about it anyway

Post #32 from Steve Williams:
What I’m prepared to say is that the EMI Protector in combination with the grid protector made a huge leap upward for the better. Here 1 + 1 is not 2 but likely 3 or 4 These are devices that don’t add anything. Rather it is what they remove that produces such an amazing sound.

I believe not all systems benefit from these plug-in conditioners. When I first used two Puron plug-in (great reviews), they helped in my previous system (Lumin U2 plus all PSA gear). When MU2 was introduced, I could not hear any impact from Puron anymore. So I was trying another cheap one to find out if such tweak still matter. Surprisingly HiiFi audio plug in made improvement over Puron.
You stated before that you don’t hear improvement from fuses and even footers. Al doesn’t hear many tweaks either. So maybe some top-line systems have less need from these tweaks. Still, I am surprised footers are not helping since they are essential tweak in my system. Maybe you should try Stack Audio🤔

Sorry Donald, I was not clear on this argument.
Fuses.
I always got a result in my system, Purple + Master + M1 and recently Pink. I simply decided to use them selectively (Innuos Statement/PhoenixNET/Hybrid Power Supply of Tempus switch and Sean Jacobs’ PSU feeding the router). MSB amp and DAC never sported IME other than stock fuses.
I’ve lost interest in fuses but can’t negate their ability to change the sound, for the better? Call me lazy!
Footers.
In the same way, I can hear different sound using IsoAcoustics Orea and recently HRS Nimbus Assembly + Damping Plates. Once again I’m using HRS stuff just with Puritan-PSM, Tempus+Hybrid PSU, Sean Jacobs’ PSU. None of these things with MSB gear.
That is the reason why I said before that I prefer using (with MSB at least) what the designer has chosen.
Both fuses and footers seem to have a new brand/product hitting the market every 3 months or so, maybe this is also part of my lack of interest.
Hope to have clarified my previous statements.

Thank you for the clarification. Successful use of fuses often depends on components and brands in my experience. Some just make sound different.
I have tried many vibration control devices (remember absorbent ring/sheet😆) on components and even on PC plugs for the last few years. It is fascinating to find how much they can improve (or worsen) the sound. My latest favorite is Stack Audio product. There will always be new ones coming out to keep this rabbit hole deeper.
But these are small potatoes compared to component and cable upgrades. This big rabbit hole definitely affected the quality of my life, and I need to slowdown to drink better wine and play better golf courses again😆

Day 4 with the Grid Protector. The cleaning of the power grid from RF interference, which the Grid Protector performs, ensures clearer playback. So nothing is added, only RF interference is largely eliminated. Yes, it’s a lot of money for a small box, but what this one does is incredible. And honestly, isn’t it good that just a small box is enough? I don’t want to miss the GP anymore. Even when I play the TV’s sound through my speakers, it almost feels like I have a Dolby system. The television picture also seems to benefit from the GP.

Which settings are you using on the GP?
I have the Power switch in position 1. In position 2 the LED is too bright for me and I don’t notice much difference. Maybe I would have to listen for longer, but the bright LED prevents me from doing that. The Phase switch is usually in position 1. And with the Earth switch I switch between 1 and 2. The switch position probably also depends on the existing fault. It depends on the system and your own preferences. By purchasing the three Furutech V1 cables, I now have 3 Furutech DPS 4.1 cables left. What I missed with the DPS-4.1 was that the images weren’t displayed as cleanly as I would have liked. The Dragon is a little better. A higher level of clear imaging has been achieved with the Grid Protector. Today I swapped the Audioquest Dragon Source on the Farad Super 10 LPS for a Furutech DPS 4.1. I like the timbre of the DPS-4.1 better than the Dragon on the LPS. Thanks to GP, the imaging is now much clearer with the DPS-4.1. Of course, I wonder what happens if further disruptions are suppressed by the other Schnerzinger products. EMI, Piccolo, Multigard, … .

How much of a difference can be done via the different settings? Are they as big as using the Grid Protector vs not?
PHASE (right) and EARTH (left) switches are used to obtain a desired result in terms of sound quality, in my opinion they are more effective to make things right.
POWER (center) switch just acts as a “gain” or “general level” of the effect produced by the other 2 switches.
I can hear a big difference with all the switches set to “0” - yes like if the Grid was turned off vs turned on. And I can hear a significant difference with only the POWER switch set to “0” too.

I think the difference is less to be found in changes in sound. It’s more like focusing the lens of a camera or putting on glasses with the appropriate prescription. Your ability to perceive music will be sharpened by the purer sound with the GP. And generally better music reproduction is achieved.

Is there any burn in period for the Grid Protector?
Have you found it’s performance improving over subsequent days as opposed to initial plug in?
Didn’t notice a really burning in period.
The effect is immediate but it took me 2 days playing with the 3 switches to find out my personal sweet spot. After that, I forgot it and enjoyed the music.

Hello Luca, I just had a long conversation with Schnerzinger directly and was invited to come and listen again. First-hand information. The EMI Protector would be the next logical step. The Grid Protector cleans the power grid. In most cases it should be sufficient without a plug-in power supply. Only use the power supply if the effect is too weak and insufficient. With additional power, an LPS could be better to cause less disruption. The antenna suppresses high frequency interference within a range of around 30 cm. If placed next to a power strip or component, this would serve to keep high frequency from components away. Setting the switch to 0 is a basic function and not completely off. Various adjustments can be made using 1 or 2. Too much is also negative. Position 2 should normally not be necessary. The EMI Protector protects the area around the devices or the listening position (around 3 meters) from high frequencies up to the gigahertz range. This means that the system is protected all around, from the outside with the EMI and the power network with the grid. The LAN Protector would clean the LAN signal similar to how the Grid cleans the power. Then I said that I have muon Pro. The Lan Protector should clean a little more comprehensively. The Piccolos would function similarly to the EMI Protector, but not quite as broadband in effect. Piccolo would be intended to place these next to a modem, refrigerator or similar sources of interference.
Some also use the Piccolo on the nightstand in the bedroom to have a noise-free environment and to sleep better.
The Multi Guard are intended to be plugged into a socket next to sources of interference. In Donald’s wine cellar, for example, or next to the washing machine in a double socket.
Die Multi Guards könnte ich auch bei meinem Koiteich einsetzen, um Störungen der vielen Pumpen vor Ort zu beseitigen.

All three switches set at 11 is the sweet spot, right?

Is this a typo?! Because just 30cm working of the PG is very little. And there are also instructions of plugging it into a socket on the opposite wall of the hifi setup etc. which has far more distance.
Hello, the information comes directly from Schnerzinger. If the Grid Protector is next to the power strip or a component, it protects it from high-frequency radiation. It should primarily take care of RF interference in the power grid. The EMI Protector is responsible for loads in the room. This is intended to clean up an area of around 3 meters radius.
That with a different socket or, ideally, a different cable. This means the plug-in power supply. For the most part this would not be necessary. It would only have to be used if it is not strong enough without it. Otherwise, you only need the power supply about once a year for about 15 minutes to charge the grid in its function. I have the power supply on a separate line in my room. For now I’ll play with the buttons a bit. Once the urge to play has subsided and I have found my preferred position, I may no longer need it. And if so, I may consider an LPS to avoid possible switching power supply failures. I will also try out the grid with an IFI DC Purifier 2 that I still have around. After asking, there should be no objection. If you have any questions, I have a short way to go because I don’t live far from the Schnerzinger company. The only disadvantage is that I have the opportunity to listen to everything and am tempted. So far only the head is stuck in the Schnerzinger world rabbit hole. 
Gruß Andreas

Ok this is something new and nowhere on a website or manual mentioned as far as I know.
Will this be true also when the GP is outside of a sideboard containing power conditioner and other devices?
