Weizhi Precision PRS-6 Power Distributor First Look

[highfigh]

It reminds me of the Black Knight from Monty Python.

No, it doesn't.

 

[Alex2507]

Maybe we can all get free power distributors! AH giveaway!

I heard Gene say that nothing was too good for the forum members
so that's what he's getting them for Christmas ... nothing!

you guys do realize by exerting so much attention on this company its actually driving traffic to their site and potentially generating sales from readers wanting to forgo logic to take a leap of faith on the snake oil being peddled? I learned long ago while debunking cable myths that the principals perpetuating such myths are both incapable and unwilling to reason using logic. They denounce the very scientific principles and process that they attempt to use (more like butcher) to justify the cost and existence of their products. It reminds me of the Black Knight from Monty Python.

May be, just may be one of those purchasers will come to wonder if he has been fleeced.

If that person is out there, please PM me, and arrange to ship the unit for me to test. I will test and send it out within 24 hours.

If anyone comes across this thread and then goes out and purchases one of those units, then they are JPN!

It's also generating some traffic for this site. Maybe you'll be able to give Tom a raise.
It is Christmas.

The Harley-Davidson R&D facility here has an RF anechoic room/Faraday cage where they bombard the bikes to see how the electronics are affected. If I ask some of my friends who work there, maybe I could have it checked out for its shielding capabilities.

.... If I ask some of my friends who work there, maybe I could have it checked out for its shielding capabilities.

Yes, but if they do, I would suggest attaching power cables to it and from it.
It is useless to shield a box if the wires to and from will pick up EMI/RFI, no? After all, the box doesn't have the capability to filter anything, nor prevent the out cable from picking stuff up.

That's why I don't think it works. If the power cords pick it up and it has no parts, other than the receptacles and housing, I can't see how it can "passively" eliminate the noise. If the power cords pick it up, it won't be filtered, so it will pass through.

Crazy

I just had to sign up to post this. Been an Audioholic reader/AVRant listener for over a year now. This esoteric stuff is crazy. This sentence off the Aaudio Imports says it all, by a dedicated true believer in their products:
(i am always a believer but this time, the gryphon makes a cult out of me)


Pioneer 84txsi
54" Panasonic Plasma
Kef IQ series
Dual Polk PSW505's

And, by chance or magic the box cleans it, how can it also clean the power cable coming out of it and into components. Useless. Real filtering can be had for not much .$ in each component

They should have called them the "Highlander" power distributor - "it's a kinda magic"

BTW: I have a Zu Birth AC cable and I swear it looks better than the stock cable and I have the science to prove it does.

This all seems pretty simple to me.

The first look wasn't meant to be a serious first look but more of an editorial on overpriced and misleading products.

the fan guy reacted as a fanboi usually does, and that is literally. Yes, if the first look had meant to be a serious first look or review then it would have been a poor one, but it was clearly meant to be an editorial on misleading products.

the fan guy kept pushing literal points (like the word review being on the page) and refusing to communicate non-litereally.

The author of the first look initially had no interest or intention of actually reviewing the item which upset the fan even more.

Then along came the president, (if it was in fact the president and not just some guy) becuase, lets face it, your product being made a mockery on one of the biggest audio sites on the web is just bad press.

so he claims that it removes Line Noise (which is still yet to be tested, it'd be pretty easy to do with a light dimmer, or some other household item that generates additonal line noise)

that being said I doubt it does as good a job as the PS Audio Line Noise Harvester which cost $99, a far cry from $3000.

Not only that but the Line Noise Harvester actually relies on physics, that is, energy cannot be destroyed, so that have a capacitor that captures the line noise energy and then releases it as light.

The item in question here has no electronics so it has no way to convert the line noise into anything other than... well... line noise.

The energy has to go somewhere, so, well, where is it going? if it isn't being converted to movement, heat, light, etc. then it must still be in the signal right? I doubt that it magically radiates out the sides as that would make it lethally hazardous to touch.

listening is good for a final verdict but if the instruments show no electronic change in the AC it's safe to say you're full of crap.

**note, I'm not trying to advertise PS Audio products, it's just the Line Noise Harvester is the first Line Noise removal device I could think of, and it's cool how those guys actually based their product on, well, you know... facts.

A capacitor turning noise into light? Really? Or, perhaps the noise ripple voltage actuating a small lightbulb. But, is it all the noise? some?
How about the filters in a component itself? No extra charge for them.

@mtrycrafts

touche sir.

Even they concede that it certainly doesn't get all the noise. Of course they say "the more the better!" which may be true but also smells like a bad deal.

One of the reviewers says that he couldn't even tell the difference with one device, and that it worked best with five. They sell them in 5 packs for $400 I think (or $399, whatever) which is still pretty pricy for a line noise remover but still a hell of a lot better than something for $3000 with no electronics in it.

I do think they could bring the price down a lot more. It's just hard because not many people are interested in high end AV gear, especially when you get into AC conditioners etc. so while something shouldn't cost that much, if not many people are going to buy them you have to inflate the price to pay your engineers.

It probably can't be that hard to buy one of those and come up with a similar DIY device to cut down on cost of using many in a home. To each their own I suppose.

 

[highfigh]

Look, if noise is on the power waveform, it would be visible using an oscilloscope. If it's in the MHz range, it wouldn't get past the power transformer, although too much would make it run warmer. Still, if this thing works, it will show up as a noise in/no noise out situation and they should be willing to prove that it works. If not, we can stick a fork into this thread because, at this point, it's just a bunch of audio geeks having a quick wank.

Maybe not so quick after all.

PS audio is another bogus company. My friend got talked into buying one of their pieces of junk. It failed just out of warranty and did damage to a connected unit at the same time. The dealer was oblivious to the fact this unit had failed, and I had to sort the mess out. I consigned the PS unit to the dealer for repair and told him to sell it to another sucker. I ordered a nice but much cheaper UPS unit from APC. That is doing the job intended.

 

[panzeroceania]

oh I don't buy their UPCs but a few of their other products are really good, don't throw the baby out with the bathwater and all that. I find their DACs to be good equipment and haven't had any issues but to each his own I suppose.

 

[panzeroceania]

in the end I guess what I was getting at is that calling their entire company bogus is pretty slanderous, especially based on the word of a friend.

I bought another company's AC Conditioner over their "Power Plant" too, so it's not that I have some deep vested interest in the company's success. I just think we should be fair in our critisisms.

But back on topic, I completely agree with you that the $3000 power strip is completely bogus. I hadn't even heard of the company until this article was written. Still, you'd have to be seriously mislead or seriously rich and bored to pick one of those up.

It wasn't the word of a friend. I had to sort it out. The unit was not good news at all. I know over priced junk when I see it. Trust me.

 

[jneutron]

What an odd thread..

Guys.

Go back to his explanation and review it. There are two things he said which do indeed have the ability to clean up a system.

One of them may not be sufficient to meet code. It would require a careful analysis.

As I recall, early on there was a mention of noise during the music. This is consistent.

Much of the explanation does indeed cross the credibility line, but I do not address that here. Just the points which can indeed matter.

Cheers, John

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