Weizhi Precision PRS-6 Power Distributor First Look

That's the problem of mixing a bit of truth in. If I am brewing a batch of Russian Imperial Stout and a rouge yeast strain gets in, well you simply toss the entire batch (unless you have a still, then you make whiskey).

Beer...wish I could drink it.

Rouge as in red, or rogue as in X-men?

I note that I have not indicated whether or not the designer of the product even understands what I speak of. It could easily be an accident. Nonetheless, progress can be made even if by accident.

Given my understandings, it should be entirely possible to make a better one for a cost roughly 2 orders of magnitude lower, and still meet code.

The audio industry is at fault for setting the conditions such that anything at all could affect sound quality.

Cheers, John

Guys.

There are two things he said which do indeed have the ability to clean up a system.

The only thing I can even think of is from what I saw, not read. That is with that much material, and the type of material that it is, would be some form of 'sink'.

My natural predilection towards an objectivisit view point would tend to have me biased that it may affect 'something' but simply not in the realm of audibility. That is what ever it is soaking up isn't going to give any coloration that the human ear is going to discern when un-sighted a/b.

Rouge as in Rogue, sometimes my fingers are way ahead of any innate spell checking I posses.

Well it is indeed a sink. A heat sink. But that is not what I speak of.

Recall the statement "noise during the music". IOW, not noise born of the line which gets into the system.

Noise which is generated by the system during music. Haversines plus hf bleedthrough to the line.

A graphite block ground connection? Breaking the bonded safety metal and inserting a resistive material is against code. But it does indeed alter the ground loop. How many have done this for a simple hum or noise intrusion?

How many understand this for haversine amp draw and ground loop coupling?

The designer of this product most likely does not.

Statements of finality are so....final. And rarely fully accurate.

The tenor of this entire thread was not shall we say, a "best moment".

Hi TLS Guy,

I was wondering if I could send you an email and ask you a question related to this thread. I'm a newby and can't send you a PM until I have 5 posts.

Can you PM me, so I can ask a question?

Yep, they have a nice picture of that graphite block. I guess this is not UL approved then.

How much of a heat is needed for the mounting tabs of three receptacles? They don't conduct any current unless something goes verrrry wrong.

When I called it a heat sink, I was referring only to the total mass of the aluminum.

The total heat capacity of the structure serves no useful purpose with respect to heat or dissipation. That is why I said I was not speaking about that.

I do not know the details of how the bonded safety path is designed. I do not know if it is via the tabs, or via the grounding conductor fastened to the outlets. If it is via the tab, then individual bonded grounds through graphite is meaningless. If the case is bonded through the graphite to the IEC ground, that may be a very dangerous setup that fails the intent of the NEC.

Without detailed information, I can only speculate. I do not know how the unit is wired.

Cheers, John

 

[yettitheman]

Regardless; most of the comments I see in these type forums are completely useless. Just people talking without any real knowledge or useful information, with absolutely no experience about the product they are commenting on.

You didn't have to call yourself names... sheesh. But that was kind of you to admit the kind of person you are

So If you’re looking for real life experiences about a product you may be interested in, good luck finding it here.

Thanks for the honest advice again. You sir are a really kind gentleman!

The grounding conductor is secured using the green bolt that's screwed into the metal "frame" of the receptacle and they're equipotential. No evidence to support the whole concept of this device "passively eliminating the noise" has been presented. If the noise is there at the input side and it's gone after passing through, it should be seen on a scope. I don't care if it's in the TV spectrum, it's still measurable. An inductive pickup could be placed on the power cords, an RF field strength meter could be used- I don't care but a metal box with super-duper receptacles and a graphite cover isn't going to remove noise being carried on the power cord and it won't make up for miles of cabling from/through the power grid or sources inside the building. If it rejects noise that could normally enter through a power conditioner/power strip housing, that's fine but it can be verified, too.

From the photos, the receptacles connect to the IEC male junction through the wires they claim are pure silver. They also claim that no filtering components are used.

 

[highfigh]

Well with over 90 units sold in the US in the past 6 months my dealers seem to be doing a nice job replacing other brands of power conditioners costing 2-3 times the price.

I usually don't get involved in these Forums, but when I read what Tom had posted I needed to address his unqualified comments.

It really doesn't matter what people are saying in this thread, since nobody here speaks from personal experience with this product.

I sell millions of dollars worth of products that don't work don't you know. Highly educated consumers have been buying my products for the past 20 years now, and they are all snake oil. That's how I have been able to run a successful business.

I am done with this Forum, this is my last posting, cancel for 3 day membership.

In case you come back to read more,

Re: 90 units sold- P.T. Barnum said "There's a sucker born, every minute" and you found 90 of them. Good for you!

Nobody has provided any evidence that this works. Saying that it's effective isn't proof. Claiming that it passively eliminates noise without filtering isn't proof. In the text of your link, "...and Duralumin brick is perfectly and precisely cut by CNC machinery." was written. First, nothing is perfect and second, to what degree of precision? What were the tolerances? "Correct tone and pitch"? It's a 60Hz waveform. It provides voltage to the power transformer, which is then increased or decreased and rectified to DC. How does this provide "correct tone and pitch"? Is this measured, or was it determined using listeners' ears? How has their hearing been verified? "Unlimited dynamics"? How is this possible if the line voltage is still 120VAC within 10%, as required of the power company?

About the only truth I can see is " Compact, takes little floor space" and even that's up to the customer to decide.

The receptacle on the wall needs no floor space

Other power filters/sources 2x or 3x more? $6.4k and $9.6k? Didn't think they existed that expensive for the audiophiles

One of the pictures at the company's web site has the ground going through a graphite block

But, they're really good!

I guess if someone spends a couple hundred grand on the rest of the system, a few more isn't a big deal.

I'll bet it's a room temperature superconductor, too. Is that the photo with the two red wires that plug into the graphite block using dual banana plugs?

Did you notice a UL listing?

Yes and no. How could this be UL rated?
that is one of jneutron's question. The ground is lifted. On a $3.2k product? Really?
Or, maybe we should call him neutron Jack or is that permanently reserved for someone else.

Oh, come to think of it, that red wire is not to US color codes, right for ground wires?

They got so much wrong it couldn't possibly pass UL muster. The ground must be bare copper or green insulated wire. It's not to be lifted and because of this, I'd like to see them explain how it can do any shielding at all, since the RF/EMI needs to be shunted to ground in order to be eliminated. If it was some kind of true Faraday cage, it would have to be grounded. This isn't.

All it can do,as the neutron Jack said, is a bastard fix for a ground loop issue with that lifted ground
