The Grid Protector, the EMI Protector and The Allocator By Schnerzinger-In My System and I’m Blown Away

[Jazzjunkie]

I believe I have read that Schnerzinger does their cable R and D with Zellaton

Aren’t we too long in high end business to believe in the actual existence of such technical connections between manufacturers of the same distributor, owner etc. ;-)

To my knowledge, they develop with varying gear and speakers and cooperations. As strong promoters against compensating gear, they should. I also personally think, even when a certain speaker was solely used for a development, it’s more important what speaker matches with one’s room (and taste).

I havent gotten mine yet but but like you my GRID and EMI are set to ll and I expect the same with the Multi Guard

And you and Luca have plugged in the switching PSU into the same AC circuit that is shared with your audio components, at least with some of them?
Gideon mentioned that this is OK; but the manual states that a separate circuit is recommended.

I use a separate AC circuit as all AC outlets in my room are dedicated lines

Michael Schwab connection:
Michael Schwab, the CEO of Zellaton, is closely associated with Schnerzinger and is often involved in promoting their products together.

Yes, distribution & marketing activities, common show room at fairs…

yes and I understand that to which you refer. This comes from the top of each company rather than from the distributors and dealers

Yes, not sure if we disagree anywhere…initiated by the top of those companies, they seem to have this kind of cooperation. I just consider most kinds of rumors, who solely uses which gear to develop as nothing more than that…or marketing.

If, let’s say in case of B&W, they first just developed with Classe gear and later just with MacIntosh (according to the state of their cooperations or common distributions), I can’t help them and hope for them, they didn’t. Not to bash those brands, but I think they wouldn’t be well advised to change their development environment with changing cooperation and to focus on certain synergies among brands so strongly. But I agree, the Zellaton/Schnerzinger connection seems on a higher level than this example (I think commercially, not technically).

I remember Dave Wilson always used Transparent Audio cables in his speakers and Von Schweikert uses MasterBuilt so companies do have preferences for voicing their speakers

True! Independent of this fact, it just doesn’t really help (or seemingly harm) in case of having Wilson + Masterbuilt

All my Schnerzinger SMPSs are plugged into non-hifi non-dedicated different sockets from the system, following the manufacturer recommendations.
I was told by the dealer that Michael Schwab suggests to use their own SMPSs, properly designed/built to work with GRID/EMI/other Schnerzinger products. I mean, they are not common noisy SMPSs but they need to be plugged as far as possible from the music dedicated circuit. This is also the reason why Schwab does not recommend using other linear power supplies as alternatives.

My dealer (Aldo Zaninello, speaker designer from Extreme Audio) is lucky enough to frequently meet Michael Schwab, he forwarded him a few of my questions about their products during one of these occasions last month. He is a meticulous guy when it comes to install the Schnerzinger devices in a listening room (home/shop demos and fairs set ups may take a day or two) - a precious resource for those personally there and curious to grasp tips on how to properly use them. He told me that incremental improvements were achieved by different placements/sockets tried on the go, just judging by ears. And they were not subtle at all, he admitted.

Just to add my contribution, it seems that Michael Schwab knows very well how the Schnerzy products work, technically speaking, and he has also gained a huge experience on the ground having installed them in different locations zillion times for years. I’m incline to suppose that this skill stands way above a merely marketing/commercial relationship, just my speculation though.

 

[Steve williams]

It's terrific you are privvy to these pearls Luca.

People who are reading this thread must be wondering what flavor Kool Aid we are all drinking........but Im still flummoxed as to what these things do to my system. Waiting for mine to arrive,

Yes, undoubtedly above in this regard with extreme experience. I was just argumenting in terms of development gear and strong technical/development relationship from my point of view, not in terms of setup experience.

This is great insight, thank you. You mean Michael suggests using the SMPSs that come with the GRID/etc?
I would hope they are not noisy! But I have to think that the suggestion to plug them into a different circuit than the audio circuit is still to eliminate any noise from entering the audio circuit.
That said, Gideon has mentioned that most of his customers do connect it to the same circuit with no ill effects.
I trust that a good AC filter will not pass through any noise, especially if they are not typical cheap/noisy SMPSs.

I do not find them to be noisy. I use the 2 I have. They look no different than any wall wart. Mine are in 2 dedicated lines .The wall wart does not come with the third grounding pin so when you put it into the socket you have to be certain that the phase is always correct which is also something the manual always states

As for me I prefer using secondary sockets, different circuits. Even if I have no direct proof of how (or if) they can pollute the system.

[luca.pelliccioli]

Maybe a little bit of patience is required experimenting more, said by a lazy guy!

Rome wasn’t built in a day, after all…

 

[Kingrex]

I have never heard, nor any customer reported hearing a difference when trying to isolate audio on one circuit and other devices such as computers, smps, refrigerators etc on the other. I am of the understanding the noise is on the neutral/ground. You can not escape that. You can try and filter it.

I have not seen a 2 prong smps that cares how its plugged into the wall outlet. This may be different with schnerzinger. If the output is DC, you could plug a meter into the output and see if the positive center pin changes from poistive to negative on the meter.
If it's that important with a Schnerzinger device, they should include a dummy ground pin that would force you to plug it in only one way.

Although I think you’re right with this, there must be more. A separate cirquit for Hifi is really essential, a big improvement compared to all in one cirquit.. Why exactly must be told by someone more into the e-technical reasoning than me.

If you have them, sure!
My entire room is on one circuit. I’ve heard one circuit is actually better to not have ground loops. But I’m sure the pros outweigh the cons.
