when you say PC on, you mean like as long as it is on somewhere at home right? doesn't necessarily have to be next to the stereo setup right? 

 

but my cd rips are on my pc, so quite challenging. 

 

 

 

Yup, that is correct.

 

Usually the entire apartment AC power line is connected together as one giant circuit, converging at the DB board, and then connected to the PUB incoming. When a device injects AC sh.it into the power line, it gets distributed everywhere in the home. Of course, the further away from the source, the noise may be a little lesser. Cr.ap can come from within your home, or from your neighbors.

If you recall, my PC was at the opposite end of the room, taking power from the wall socket there. Refer to the below picture, I measured the AC line noise at the PLixir output socket. With the PC switched ON, the noise level was about 1000mV; with the PC shutdown, the noise level drops to around 180mV.

 

On the PLixir incoming side, it's about 1800mV. PLixir helps to reduce the noise somewhat, but still quite a bit flows through.

 

Thankfully, I cannot really hear any impact to the HiFi system.

my tv the "Black's" became "Blacker" leh...music also become "Darker"..... hehehehe!!! i am in a joking streak today!! in 1hour's time, i will be injected with "Covid19" at the CC!!! those spiky little creature's gonna be wreaking havoc man!! maybe tomorrow i will wake up and "like them Skinny n Assless!!!! oh no!!!!!!  

[Guest CASH]

It's done!! It's in my bloodstream!! 

Omg!! I am already seeing too many skinny assless woman walking around!! Hahahaha!!!

Sorry busy with work, here are the promise photos of the measurement we capture yesterday at Cash place.

Had make a line chart for all to easy understanding for the measurement took upon arrival.

Will post more details tonight or tomorrow after i had sort out the signal drawing.

Sample as attach of PUB Household with Common Mode Noise and Normal Mode Noise. Noisy..........

 

The verdict is clear for the measurement taken, as what bro Cash said. Save your money, get a Plixir BAC, 1st gen also good.

Plixir BAC had won the Line EMi measurement with compare with Weiduka 8.8, Tacima CS929, ETKG YB-600A, and a exotic DIY Rose Gold.

 

Will came back with more details later, with recommendation and graph display compare.

 

Any more bro and sis wan volunteer?

Btw i Electrical and IT train by profession.

 

Here are my finding at Cash place and his set up:

Line EMI Noise:

1) Dedicated/Separate Powerline Does reduce Line EMI noise generated from other Household applications.

2) Plixir BAC 3000 Does reduce the Line EMI noise as compare to  ETKG, Weiduka, Tacima & DIY GoldGold.

3) Electronic Equipment such as NAS & PC when power in parallel at the output of the Plixir BAC Will greatly increase the Line EMI Noise.

4) The Line EMI Noise generated from the NAS and PC does affect other equipment connected in parallel at the Plixir BAC output. 

5) Connecting ETKG, Weiduka, Tacima & DIY GoldGold as "Extension" from the Plixir BAC does relay down the filtered effect of the BAC and the result of LIne EMI, NM & CM reading is consistent.

 

Normal Mode & Common Mode Noise:

1) Household applications does generated higher Normal and Common Mode on the power line (NM: 888.1, CM: 283.5)  as compare to dedicated line for HiFi equipment (NM: 142.6, CM: 179.6).

2) Plixir BAC 3000 Does reduce Line EMI noise but Not alot when compare to NM & CM noise. Before Plixir: NM: 142.6, CM: 179.6, after filter NM: 139,6, CM: 76.51. Normal Mode was not reduced alot.

3) NAS & PC, generated large amount of NM & CM noise when switch ON, OFF: (NM: 139.6, CM: 76.52). ON:(NM: 303.6, CM: 125.5).

NM & CM noise double when switch ON.

 

Recommendation and Follow Up Action:

1) Reconnect all HiFi equipment to direct connect to Plixir BAC ouput.

2) If HiFi Equipment connection exceed BAC connection, use Weiduka as extension from Plixir.

(Cash's BAC is 3000watt, total equipment on site when full power should not exceed 2500watt)

3) Remove PC and NAS from Plixir connection.

4) Connect NAS to UPS for battery support and blackout protection.

5) Relocated NAS to location away from Hifi equipment to reduce other environmental noise, generated from NAS. (Electronic & Mechanical Noise)

6) As the PC is part of the HiFi setup and also generated AV output to TV & HiFI, the PC power supply should be provided with "Clean" power at the input. Which this power supply should not affect other HiFi equipment power supply.

7) Connect the PC and any other DC equipment(Stream Box, Phone Charger, LED, Etc) to a individual Isolation Transformer.

8 ) If budget allow, connect PC and any other DC equipment to a UPS with isolation transformer, UPS can be line interactive or double conversion topology but must be with a isolation transformer. 

 

Information & Ref:

1) Normal Mode Noise: Line to Neutral - "Hard Failures" Cases System Damage, Typical Higher Energy

2) Common Mode Noise: Neutral to Ground - "Soft Errors" Causes System Errors, Lock-ups, File Corruption

With the above finding being observed and found, any volunteer to welcome me to find out more of your power Setup?

As mention FOC. no straight attached. 

[Guest CASH]

thanks for all your hard work buddy. really impressed with your dedication, expertise, n time. cheers!!!

Appreciate the sharing of your measurements and  findings. 

So the emi meter reading does show reduction from various forum members when the Greenfilter are used. Does it mean it’s a matter of pricing? Or there are better more legitimate solutions out there?
 

Also if balanced isolation transformer unable to reduce much of the other noises mention... common mode and differential... I believe that’s what I understand, what solutions can one explore? Besides AC regeneration which is quite costly. 
 

I did Google search on the use of Hammond 193L choke that I read of few years ago : https://www.audioasylum.com/cgi/vt.mpl?f=tweaks&m=203039
 

Is a choke one possible way? Although I don’t know if the 193L will blow up when use with our voltage.

Hello, in short, NO, does not mean more expensive equipment will filter out all noise and works like magic.

 

Like Bro Cash installation/placement, Its a matter of understanding, placement and relocate. like bro Cash use a 1st Gen Plixir, which works great. But its just the PC and Nas that we need to relook at the installation location & get some thing to get the noise created at from the PC isolated.

 

Its like you can get the most expensive water filter system in the market, world class in fact.

But if we install it at the sewage system. it will still be dirty in some ways.

 

Isolation Transformer and Choke work differently and to be used differently.

Let me get back to you on the Hammond 193L after i do more research on it.

 

BTW AC Regen or UPS may not help also. it may create more problems.

Thanks for sharing a very informative article but why do you consider the Greenwave filter snake oil when it’s having 3 capacitors inside ?

 

Whether EMF has effects of health, I leave it for all to believe or rebut.

 

However, when it comes to reduction of EMI, isn’t the Greenwave filter doing what it’s supposed or advertised to do ?

I not in position to discuss EMF as that's not in my field of study.

But for EMI reading is a very subjective.

 

We talk about price:

The price for 3caps in a nice case for USD30.

Each cap for USD10? abit over priced for me.

When there is no design or PCB or etc in side?

 

https://www.aliexpress.com/item/32905024559.html

The same caps for 20pcs are sold on aliexpress for SGD 30. each SGD2.5 around USD1.9

So for 3caps thats USD5.7 for hardware which i have to pay USD30 which comes with nice case.

Anyone with some basic soildering skills and extra plug heads at home can get the same hardware product.

 

Now we talk about results (EMI Noise Reading)

With the caps attached to the socket head its jus stabilizing the power which is nearest for the plug location.

Thats why they advice to install multiple plugs at diff location for "best" result.

Dont this sound familiar from those seller who sell Power Saver Module at street market?

 

YES, the result reading from before and after the installation looks great but.... 

The same result can be achieve from my laptop charger.

Laptop Charger Off: 1987mV

Laptop Charger On: 1324mV

So now my Laptop Charger is a "Greenwave" filter

My Charger had not only reduce the EMI noise but also charge my laptop...

I should get more Laptop Charger now. HaHa.....

 

Btw i tried the charger to connect charge my laptop the result reading is the same.....

I’m not EEE trained so I might be wrong.

All SMPS have built in EMI filters because SMPS generate lots of noise so the filters are there to prevent high EMI affecting other electrical appliances and also to comply with regulations. 
 

So maybe that’s why in your example, by switching on your laptop ac adaptor, it helped to reduce the EMI noise but not in the magnitude of 1 unit of Greenwave filter. 

 

Btw, I did my own testing in the daytime when the base EMI reading was in the 30s. When I switched on my HP ac adaptor, it increases the EMI to 40s. When I switched on another Lenovo ac adaptor, the reading again increases. Maybe others who has the EMI meter can try it out for themselves and report back their findings. 
Testing was done on the same powerstrip with no Greenwave filters. 
 

NB: Laptop AC adaptors are not cheap either.

This greenwave product is really good for the money. My first time using such a product. 

I've finished my tests with it. It really brought down the electrical reading in my HT electrical circuit by a GIANT margin. Super effective. Data doesn't bluff. No fluke. 

 

Assuming all other devices which are powered on are kept constant, my initial reading without any greenwave plugged in is average of about 1200. After i added 1 greenwave unit, it dropped to about 250 (best socket). Adding a 2nd greenwave unit at the "best socket", it brought it down to about average 55. 

Wow, 1200 to 55. Reduced by 21 times! AMAZING. 

 

But anyone can advise, what SQ and PQ improvements would this possible lead to.....?
