Reducing a computers EMI improves picture quality of attached monitors.

[JasonM]

You can filter and surge protect a power cable all you want and get the most filtered and surge protected cable ever. But go and read Russ Andrews site and look again for a single time they state a measurable value this has on any audio or visual output.

They never give you a value ever but imply benefits constantly.

I totally agree, RA never give you any specs as such, it's just implied that you will get an improvement. That said when you understand the twisted mains cable reduces EMI there is an actual science behind them. I already posted a video showing how twisted cables reduce EMI. See post 27.

Going back to my studio monitors (active speakers), the RCA input is only about 3.5 inch away from the mains AC input. It's not unreasonable to conclude that EMI is getting from the transformer side into the source side and the RA power cables reduce this, that in turn explains the improvement in sound quality.

There is another improvement I noticed also but not mentioned before.

I use an Asus Essence STX II sound card, connected to a Seasonic Prime PSU (the Essence takes power directly from PSU not motherboard). When I tried the RA power cable on my computer (that is still connected), my Asus Essence sound quality improved, however it was subtle and I had to listen for a few hours to appreciate the difference.

No oscilloscopes in sight, no monitor calibration tools and unbelievably for "audiophiles" no microphone examination of the sound output. Audiophiles not examining the sound with proper technology!

The Russ Andrews cables have been tested and shown to give improvements.

The Russ Andrews cables were independently tested by 3C Test Ltd and shown they reduce both RFI and EMI.

Again with either the RA mains cable, and / or the Tacima power line conditioner, I'm seeing improvements to both audio and video. I would not of created this thread otherwise.

From post 1



My emphasis

in this case i would love to see some pictures they clearly demonstrate the not small, but significant improvement in the picture quality of your monitor. This should be a trivial thing to demonstrate if the effect is as you describe it.

Many thanks

If I owned one of these I would. Differences to difficult to show on a normal camera.

[JasonM]

are you saying the emi reduction is improving colour accuracy? Wow. That’s quite a thing.

No makes whites brighter, blacks blacker, better contrast and less blur.

 

[JasonM]

Read both articles you linked and decide what you're saying with them

One article talks about a test that looked at inductance in audio cables

It also talked about RA mains cables. The cables in this photo is an RA reference cable.

I posted that link again as Whitecrook mentioned no one had even applied an oscillator to these cables, but of course they have.

How can the audiophile scene capable of spending tens of thousands on gear be incapable of obtaining audio recording equipment to prove the money isn't being ****** into the wind.

I've been in recording studios, everything is setup with the recording engineers hearing only. I've never once been in a studio where there was some calibration or monitoring tool.

 

[JasonM]

A couple of you keep mentioning no one has ever done a audio test on HiFi power cables, well someone on YouTube has.

I can hear the differences in this video between power cables, honestly interesting if anyone else posting in this thread can also.

Just to clarify, this chap is talking about power cables costing in the $1000's, that's clearly a little crazy, i'm talking about second hand RA cables around £40. What this video does show is that there are differences in better cables compared to the cheap standard PC IEC cables.

 

[JasonM]

That's a picture of the RA cables getting tested for having electrical filtering ability. NOT to prove any claim of improved audio or visual result further down the line.

Yes but electrical interference effects audio and visual, this has been known for years. Twisted-pair cabling was invented by Alexander Graham Bell in 1881 to help extend phone lines in the USA.

 

[JasonM]

Then it should be trivial 140 years later to demonstrate that you are removing interference from the audio output by swapping the power cable?

Not even necessarily you. Any of the paid reviewers could do it, the manufacturer selling it could demonstrate the audio benefits.

If you were standing next to my audio equipment, then it's 2 seconds to realise the difference between RA power cable + Tacima, compared to cheap / standard power cable to the wall.

For example, I'm running powered studio monitors, if I was to use the RA + Tacima on one monitor only I would totally unbalance the monitors.

I can't record it as I don't have the equipment to capture the difference, then of course the audio is compressed, then re-uploaded to YouTube fine differences are lost.

That said, the video I posted last shows differences in power cables, he obviously has some really expensive microphone to capture this, at least I can hear them on my system here.

 

[JasonM]

This is sig worthy... Reduced EMI can enhance a monitor's display past the limitations of its hardware capability.

Beautiful, just beautiful

I'm describing the effect I'm seeing on my screens.

Try these things yourself.

 

[JasonM]

If a simple £40 (retail, cost to manufacture will be very much lower) power cable can give a significant improvement in picture quality, why do monitor manufacturers not include them with their monitors?

Because it's cost, everything down to the penny adds up.

Your £300 monitor would become £340 and no one would buy it.

If you look at the monitor section of OCUK forum, plenty of modern monitors are failing early - again it's cost verses quality. They could make them better but it might add 10-20% extra to the cost.

Incidently my AG Neovo glass fronted screens (built like tanks) are over 10 years old, I estimate over 200,000 hours on them. They have lasted so long as they almost double cost of other 22" monitors at the time.

It's the same on cars. They say why did the manufacture put paper / cheap speakers in the car, if they put some uprated Kenwoods or Pioneer speakers it would add another £100 to the cars cost, and they won't do it.

Maybe you've heard of Abbey Road Studios, 150 million refit and what do they get for cables... https://www.van-damme.com/van-damme-for-abbey-road-studio-52/

How odd, it's just simple well made cable with clear specifications and they're hooking up gear worth hundreds of thousands with it and recording the music you listen to.

Van Damme make speaker and interconnect cables, not power cables.

As it happens I use Van Damme Silver Lo-Cap 55's for my studio monitors and my separates system in front room, they are great interconnects and make more difference then the Russ Andrews power cables this thread is about, at least I would upgrade to the Van Damme Silvers first. The Van Damme Silver cables are session grade cable used for final recordings in studios.

But thanks for mentioning the Van Damme's, that's one thing we can both agree is good. Here is one of my studio monitors with the Van Damme Silver and Russ Andrews cable connected.

Because this is what VDC Trading will sell you to connect your equipment (connected with their audio cable) to the mains: https://www.vdctrading.com/shop/general-cable/mains-cable/

Looks like standard power cable in your house except round...

What on earth are you on about.

Abbey Road studio uses specifically designed mains cables, you can read about this here.

http://studioconnections.co.uk/

Abbey Road power cables were designed by someone called Michael Whiteside, this his is article on this subject.

http://studioconnections.co.uk/information/

 

[JasonM]

You have just pointed an arrow to a cable that's an interconnect, we were talking about power cables.

You tried to say that Abbey Road used cheap general mains cable from VDC, I provided a link showing this is false.

 

[JasonM]

And I said if you respect Van Damme cables then you should be aware what VDC Trading sells for mains power.

There a business that sells a variety of products, different cables are suitable for different applications.

OCUK sell basic business computers, it does not invalidate their overclocked computers costing many thousands of pounds.

 

[JasonM]

What sort of increase would I see by using one of these cables? I'm guessing it wouldn't quite get up to VA levels, but are we talking 1200:1? 1500:1? Even better than that? Should be easy to prove just by measuring with and without the cable surely?

The middle cable is an entry level cable and adds a contrast ratio of only 100.

Bottom cable is a high power cable, this adds 250 extra contrast ratio.

The problem with adding so much power, is LED screens suffer more blue light effect, if this happens choose the yellow cable as the yellow counters the blue light.

I could have told you the construction differences, but ask a daft question, get a daft answer.

 

[JasonM]

Oh holy **** I just read your last post. You're beyond helping.

If you don't see that's a joke reply to Haggismans ridiculous question then it's you the humour is lost on.

 

[JasonM]

So yes I am open to hearing that you would buy power cables to adjust the output of your monitor. How is it any different to what you've been saying.

I explained the cables remove EMI, I'm also using them with a Tacima mains conditioner.

How much difference depends on the equipment your connected them to.

 

[JasonM]

The fact you refer to a legitimate question as "daft" and "ridiculous" is clearly deflection, and suggests maybe you don't have an answer that isn't "daft" and "ridiculous"?

I have no ability to measure the levels, however i'm seeing better picture quality, again the improvement will depend on the monitor your trying these on.

Again like most people on this thread, you have a belief system that cables don't make any improvement.

To justify your correct your asking me for exact measurements, I can't possible give you any measures.

Do you think one of my bedrooms is converted into the RFI testing facility, or I have some specialist light metering equipment for testing monitors. Of course I have none of this, but this does not mean the improvements I'm describing are not real.

I've just fitted some Yokohama AD08's to my Integra Type R, I think the Yokohama AD08 are great tyres. Would you take my word for this, or should I fit some G meters into my car and provide some data to you? Should we say that until I can provide some real data Yokohama AD08's offer no performance over say a budget cheap tyre?

Everyone here is wrong regarding EMI and it's effect on computers. From the following link.

https://www.deepcoat.com/why-emi-shielding-is-essential-in-data-centers/

The effects of EMI can be drastic. When it occurs, you may notice shaky monitor screens or system failures. At times, the interferences can be so bad that information gets scrambled and hard disks can become completely wiped. Additionally, some people use EMI to their advantage. They take it as an opportunity to intentionally mess with signals without having to take a step inside of a data center.

The Russ Andrews power cables are reducing EMI, and the Tacima is also reducing some radio interference and providing basic mains conditioning. Anyone dismissing this before trying for themselves is not being objective.

 

[JasonM]

Linus is talking about display cables, he also mentions how interference effects them.
