Reducing a computers EMI improves picture quality of attached monitors.

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.

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.

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.

Why is there no money or respect available by proving the following:

1) That it changes the audio signal
2) That it changes the audio signal to a degree which is audible
3) That it changes the audio signal to more closely match the original recording

And why is it when audio "testing" of this totally electrical process does happen the tool of choice is a paid reviewer sitting in a room saying trust me bro.

I have no doubt that changing components can change an output but human ears and words are not a replacement for repeatable and independent measurements with no one getting a pay off for product promotion involved.

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.

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

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.

 

[Haggisman]

OK, so I pose you a simple question:

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?

They spend tens of thousands on R&D to get slightly faster response times, refresh rates, better sRGB coverage etc. to get an edge over competitors. If say... LG could charge an extra £50 on a monitor to get a 5-10% increase* in picture quality from bundling a cable which costs them £20, then why don't they do so?



* whatever it is you happen to class as an intangible and unmeasurable "increase in picture quality"

 

[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.

 

[Haggisman]

You've not been around OcUK long I take it, people will spend hundreds water cooling or on a new gpu for an extra 10fps

A significant improvement in picture quality for an extra £30-40 on a £600+ monitor would be a no-brainer!

Your car example is a poor one, as plenty of people do pay to improve the speakers/audio system

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.

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

The inequality of each track being started and stopped in different places is a sledgehammer in my ears. Plus there's a cable salesman telling me how different they are.

But if you can hear the difference then you don't need that.

Presumably you can put those short clips in an order of best sound to worst sound and thereby detect the best to worst power cable being used or tell if I've doubled or tripled the same clip.

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.

No response to this then?

I'm currently considering this monitor:

https://www.overclockers.co.uk/lg-3...ms-hdr-600-curved-gaming-monit-mo-15q-lg.html

But as it's an IPS screen it only has a contrast ratio of 1000:1. 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?

If you can provide a link where they have been tested properly and show an objective and measurable improvement, I'd be more than happy to buy one.

Does this have an effect when using optical HDMI cables - will I see an improvement in the picture on my TV (connected to my PC with an optical HDMI cable)? Would it only be when I'm using my PC as the source, or at all times while the cable is connected (since there is still a path for the EMI to travel)?

What about when using a wireless display? Does the EMI affect the monitor itself, or the signal generated by the GPU?

 

[Yaayuh!]

I've just stuck a fork in a toaster whilst powered on and I feel great. I'm just describing the effect I had. Try it for yourself

Good to hear you respect their cable decisions.

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...

I expect they'd think a professional company was out of its mind if they stuck in random filters without any specifications whatsoever instead of having any interference properly dealt with.

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.

Do they?

I bet it had mains cabling installed by professionals. But I also bet their equipment uses the power cable supplied by the equipment manufacturer.

Lets read the article you're showing me and find out what Abbey Road has to do with this guys expensive power cables.

So Michael Whiteside developed some cable for Abbey Road Studios over 30 years ago and still sells it as Reference Speaker Cable at £1000-2000 for 2.5-5m of cable.

Reference Speaker Cable is the same family of cable we fitted throughout EMI Abbey Road recording studios.

Continuing to state his credentials as having installed cable at Abbey Road Studios 30+ years ago he now makes and sells expensive power cables and expensive other cables.

Meanwhile in the present, Abbey Road was seen buying kilometres of cable at Van Damme where all grades of 2 wire speaker cable (which is what that Reference Speaker Cable is) is less than £10 a metre, admittedly without terminations but you get the idea.

Michael Whiteside is making money with what he can and I can't see evidence of Abbey Road buying what he's selling these days.

Still keen to know if you can really hear the 3 different power cables as you said earlier. There's no tricks. Just no audio or visual hints which the video was loaded with. The only thing that's random is the order compared to the video.
