Has anyone ever dissected the higher end cords to see if they have better shielding? Resist the temptation for a moment to just bash them. I have avoided them because they have never made enough of a difference to justify the extremely high prices. I will pay a little more for better shielding.Lat International is a favorite brand of interconnects because of the over-built construction but even it I buy used. I am using a PS audio Premier power conditioner and my interest is in having well shielded power cables for the regenerated power. Usually I make my own power cords from Belden 19364 and pay only about $2.65 per foot for it plus the cost of connectors. A few years back, when I tried to eliminate a buzz from my system, I discovered that I have a lot of RF in my room and now run balanced on all channels which solved the problem. Not sure of the source, but I am about 5 miles from many TV towers and near an Airforce base. Fighter aircraft are always around the skies of my neighborhood so not sure if that has anything to do with it. Likely just going to stick with the Belden but am curious about the construction of some of these cables.

Here's what I do know: when my computer's external speakers were on, I could tell when my cel phone as polling or when I was about to get a phone call, because the cel phone caused some telltale noises to be introduced into the audio system. I don't know the exact point of introduction, but something was poorly shielded. I didn't have this problem with my last home theater system but then again my phone was never that close to the stack when I was enjoying it.

I have that too all over the house. The phone system picks up the cell, so does my VHS Hifi that I use daily to record a radio show, Zenith projectors are really bad for it as well.

No question that if RF or other interference is present where the stereo/HT is located, the more any amount of shielding will help.

It doesn't change the pros vs cons though, as that shielding is something you could measure, or at least measure the improvement that shielding does for the noise rejection.

Hi,

In the U.S., the FCC has plenty of information about phone-based RF interference:

http://www.fcc.gov/oet/rfsafety/sar.html

For example - use the information on your cellphone ID to see how it rates from an RF radiation standpoint:

https://gullfoss2.fcc.gov/oetcf/eas/reports/GenericSearch.cfm

For an in-home wireless phone, I would switch frequency channels to see if call interference clears up.

If you think you are getting interference from transmission towers - that would be in violation of FCC regulations and that will get taken care of by contacting your local office and authorities.

There are several different designs for high-performance power cords. I, too, like DIY - sturdy, clean plugs on both ends, good shielded cable with proper tight connections - helps a lot. For audio interconnect, depending on the cable used, grounding the shield braid at one end and not at the other can help break those annoying hums...

There are interconnect "autopsy" threads out there. A famous one is the JPS Labs
cable dissection and all the controversy stirred up a while back.

Sometimes using snap on ferrites in the right places solves problems. Certainly cheap enough. As far as a better shielded power cord, Bulldogger, I'd recommend that you pose questions along those lines to JNeutron maybe via a PM. To me, he seems to have both a good grip on it from a theoretical perspective as well as practical.

Steve, if you've got a link to that JPS autopsy thread, would you please post it?

This is strictly cell phone interference. All of the ones I've had do it. They radiate RF which is somehow demodulated into a buzz, similar to a 60Hz buzz around audio equipment.

Sorry, I have no idea re the link. I quit that MOD biz years ago. I'm lucky they even let me post here! HAAAA!!@@

Bulldogger, I have found that the Granite Audio power cords, in conjunction with the PS Audio AC regeneration, do improve audioand video in my system (here go the Harlots!!!!). I think the primary reason is Granite Audio uses proprietary donut shaped toroids at each end of the power cord which go down frequencywise much lower than ferrites. See the Granite Audio site for more info. The power cords were my first foray into Granite Audio stuff. I really wasn't expecting the improvement I saw and heard, given that I was already using the PS Audio power regeneration. But I gotta lotta stuff in my home theater and there are those who say (and those who naysay) that it puts out a lot of crap (and those who say bunko to that) on the AC line.

Chu and I aren't that far off. Chu will admit that 10 guage for hi power amps makes sense; that using Pro Gold to clean and condition the copper wire and connectors as you built the cable makes sense; and that ferrites each end make sense; right, Chu?

Guess what power cords have all that done? The ones that I have.

Nothing wrong in building a good power cord yourself. Glimmie is a master of building DIY it seems 80% of his home theater. Not all of us are great at wrapping ourselves around building DIY stuff, though.

cmon guys....shielding in power cords making a difference??? so i guess it magically causes rejection of RF from the xxx feet of romex leading to the outlet....


good lord.

Wrong Steve. I meant scorcher.

Shielding could be useful if you use a power conditioner that filters the noise coming from the outlet. Think before starting to rant...

NEver mind those people that use extra long cables of all sorts coiled behind the equipment. Then sheilding the AC cord _might_ help as well.

Well, just about every conditioner out there filters the noise that comes from the outlet, which comes from the 50 feet of unshielded or so to that comes from the breaker, which comes from the 200 feet that goes to the pole, which comes from the 10 miles that comes from the substation, that's attached to noisy traffic lights, that trucks and cars run past with their unshielded spark plug wires...

Wrong Steve. I meant scorcher.

You made me laugh. We agree twice now.

Here's the solution.

I read the letter, accessible from the earlier links to it at http://web.archive.org/web/*/http://www.jpslabs.com/see.htm and urge others to do so also.

Of note, I found this comment...

All of our power cabling is custom made for us to exacting specs (none of us cable guys draw wire), and confidentiality agreements are put into place with vendors to protect our interests. Once a design is voiced and optimized, I personally write the spec. for each and every one of them, as many pages as it takes to cover the details of how I want the cable made for JPS. For example, our lowest cost AC cord, GPA 2, is manufactured for us (as some have already mentioned); BUT, we specify everything right down to the conductor materials and purity; how it's drawn, overall anticipated conductor surface finish and annealing, stranding geometry, gold plate quality and thickness, insulation type, flexibility, color, and quality; how its applied to the conductors, you name it, it's in our spec, and it sure as hell better be made that way or they have to do it again. You see, what you guys are familiar with doing one at a time we do too, just more efficiently in quantity. The manual labor alone to assemble cords at this price point from scratch one at a time would be too high, so we contract out to those set-up to most efficiently deal with it so we can sell the end product for a lower price. Oh and BTW, to save you guys the trouble, ALL of our other AC cords, even the jacketed ones, DO have our name on the cable inside, we did not borrow technology from anywhere else, sorry to disappoint you:).

I'm sure that some will look at the above differently. However, having been involved in different industries where the sourcing of raw materials, subassemblies, finished products from outside manufacturers and developing specifications is business as usual, I can offer the following.

Having your own full specification does not mean that you've developed the specification entirely on your own and gone out and had somebody make it. It can mean that you've simply asked for the vendor's specifications and adopted them as your own. It can mean you've asked them to make a production run but have your own lot # or any other identifying marking stamped or removed. It can mean you've asked them to ship power cords in a specific fashion. A certain number to a box. And so forth. Not only can it mean that, it invariably does mean that. Some will recall just how many brands of peanut butter were recalled, all made by the same company but packaged and advertised differently. Or maybe some will recall all the dog and cat food brands recalled all made by one company but packaged and advertised differently. Science Diet indeed!

Here is the telling line from that letter Chu

Quote"You see, what you guys are familiar with doing one at a time we do too, just more efficiently in quantity. "

So they have someone make cables in bulk for them, out of the same stuff we buy off the shelf. And they charge more for it. And the specs mean nothing if they dont tell us what they are.

Here's what I do know: when my computer's external speakers were on, I could tell when my cel phone as polling or when I was about to get a phone call, because the cel phone caused some telltale noises to be introduced into the audio system.

I didn't have this problem with my last home theater system but then again my phone was never that close to the stack when I was enjoying it.
You know I like to experiment. You got me to thinking about the noise I hear when I am using my computer and a call is coming in. I tried covering the cell phone with aluminum foil to shield it. Completely covering it stopped it from receiving calls. Only covering the back, stopped the noise from being transmitted to the computer. No I do not plan to put foil on my cell phone :D . What I wanted to know is how much shielding makes a difference.

it is shielding of the RFI noise when the phone responds to the network poll not being dealt with properly due to incorrect grounding in the device. Google "PIN 1 problem"

So that's why you wanna come over to demo my room - to see my Granite Audio copper faraday cage!!!!???

Projector power supply just came in, so hopefullywill be up tomorrow. E-mail me and you can come over and see the Faraday cage.

Well, you know Steve, if'n you really wanted to do something like that, you could do the following. First you apply some commercially conductive tape in an inconspicuous place on the wall that can be attached to say a water pipe that goes to earth ground. Then, you paint the room with a conductive paint. Now, you can do that several ways.

1) Buy an EMI paint from a place like MG Chemical or elsewhere. Paint over the tape with a couple of coats. Then use whatever your favorite paint is to paint over that so you get the color you want.

2) Go to your local boat place and pick up some copper based paint that's used on the bottom of boats. Available in various copper contents but I'd imagine one that's about 50% or so ought to do the trick. Do the painting as in 1) above.

3) Both one and two are pricey. You can buy copper powder. Even nickel and silver powder. Go to Home Depot, buy some decent acrylic based paint, and add the powder to it.

Now, you might think I'm kidding here. If you do, pick up a small quantity of high copper content boat paint. Get a small box that your cordless fits in and give the box a couple of coats. See if the phone rings when you call it from your cell phone.

Why is it only the AV world sees the need for hi end power cords? Why not the medical, NASA, or others? Wouldnt they want to have the best to keep the data from being wrong? If a power cord makes the audio or video data better then it must make other things better too.

Apparently, if NASA had given the Russians a hi end power cord, they wouldn't be having the computer problems they are having on the station.

Their real problem, of course, is quite simple. They do not have enough grounding rods.

I remember the story of the airplane tech that needed a signal diode for an F-111 board, the correct part cost a hundred dollars..a HUNDRED dollars..he got a diode from RS, put it in, and it worked..there were scathing articles about the costs...


Unfortunately, the diode was supposed to be a rad hard, jantxv level fully screened military part. These parts are serialized, and the manu could show you the x-ray of the junction braze joints, pictures of the edge of the silicon showing the passivation, leakage before, during, and after burn in, transient thermal measurements, the position the diode was in within the burn in rack and the test scanner.....they could even tell you the color of the underwear of the operator that touched the silicon wafer (and that of her son). :eek: .. And yet, a tech put into the F-111, a diode that I had rejected for quality and reliability failures at lot screening..not a military one, they are destroyed, but a commercial one.

Glad I wasn't the pilot...or the tech when the story broke..

When we need to measure low frequencies we just use cheap cables, alligator clips and a multimeter (or maybe a low end oscilloscope).

I was just in the hospital (visiting a friend), and they use Hubbell outlets, and A/C cords with hefty connectors (Seymour and Pass looking stuff). That qualifies as "high end" to me...

- Steve O.

Well there is such a thing as hospital grade power connectors. They are usually orange. Tighter grasping pins within the receptacle, a lot of higher end auio cables use them, in fact the last audiophile rag that I bought had several ads for them in the back classifieds. I'll bet though that the Romex, Loomex or whatever you want to call the AC wiring behind the receptacle is the same as in any home though.

Come on Steve O. High end is when you check your hospital bill and found out that Tylenol Tab was $25.

Yes and so do I in our gear here at the showroom, BUT that is a great way from something like a 500 dollar PSAudio cord.

Those Hubbels are not outrageous in price and are not making bogus claims.

Well now,

The percentage markup on standard hospital grade duplex or single A/C outlets, after cryo'ing them, for example, is pretty high. I can accept that it takes effort, an enormous amount of energy, and care to properly cryo treat something - I would just like proof of that being done in the first place if I order a part online...

And with cords - there is an "audiophile" cord out there - the Ironlung Jellyfish Cord, which will sell for over $25 easy - this is a standard clear plastic molded power cord you can get at an industrial supply for $1.99-2.99.

It all adds up... (the good and the bad)

As an aside, I see the other power cord thread was closed. What is with you high end whiners? This is an OPEN forum, OPEN for all to discuss. There wasn't any over the top bashing that I could see, and sure, the thread got way derailed. If you don't like the thread, don't post in it, ignore it. To go whine to a moderator to close it just because you don't like it is very anti free speech (or type, as it were).

Take your hoity toity attitudes elsewhere. Along with your Mercedes, Porsches, Rolexes, cappuccino machines and other overpriced drivel. I happen to enjoy all threads along with reading other people's opinions, whether from someone rich or poor, someone that has a million dollar stereo or a $49 Radio Shack boom box, and whether I agree with them or not..

An alternate explanation is that your cell phone had been lazoed, by a non governmental cell tracking device. These devices emit an electromagnetic interference everytime your phone is about to ring. The good news is that is not law enforcement, theirs are electromagnetic inteference free.

The mickeymouse gumshoe models have evolved where they now emit the tell tale sound only once at the point of being lazoed. These units do not allow for eavesdropping , just GPS tracking and a list of numbers dialed.

Someone must have a pitiful life to be interested in tracking my cel phone. Nothing of value could be gained from it! No insider trading, no secret formula, no trade secrets...

Sorry, I don't buy that someone is tracking my cellphone. EVERY cell phone I've ever owned causes an audio system to buzz right before it rings.


On a side note, I've had the DEA at my door with dogs 6 times in the last 10 years, there's a black Escalade that sits in front of my house for hours and I keep getting solicitations from midget porn actresses. That's just a coincidence though, I'm sure of it..;)

OK, whatever mr "they are listening"

All cell phones are polled at a regular interval by the network. This lets the network know if you are there or not (ring the phone or go straight to voicemail)

THis poll results in your phone putting out an RF burst when it responds. Virtually all audio devices (especially consumer) are either built incorrectly with incorrect grounding (check pin 1 problem) or are unbalanced and have issues with RF bursts.

Go all balanced interconnects (that do not have the pin 1 issue) and you will never have that noise again.

Sure it may have something to do with bush wanting to listen to your relatives who are currently in a training camp in afghanistan... but likely not.

In my office at work one fellow has a set of Yamaha speakers on his desk for his Ipod, his phone will cause them to buzz before it rings if they are in about 2 feet of them. We tried setting it on top of the Meyer HD1s we use for monitors and we could not make those buzz before a ring. Only the little unshielded ones would. Out of 6 guys on our crew only 2 of our phones will do the buzz thing. Both of those have Verizon. I have Sprint and the others have ATT.

Hi

Quite interesting what explanation paranoia can have some come with... Cell phones are polled on a systematic basis. it is for the purpose of associating the phone with a "cell", to make it simple to the equipment at the towers. The burst interfere with some equipment and some noise is heard not because you are being watched...

The Cell phones themselves emit all kind of RF by the way, especially when they ring... Put them on a spectrum analyzer and you will see how noisy they are...

Well frankly Big Brother should be watching someone that uses Yamaha speakers more closely than someone that has the taste to use Meyer..:)

I've had exactly the same thing everywhere I've lived, and it's most noticable in the car if my phone is in the centre console near the radio head unit. Always about 2 seconds before it rings.

I'm using ERS Paper to shield my system, I like it because it doesn't require any grounding. One time I had removed the paper from 50cm of my Nordost Valhalla power cord near the wall, and I complained that it sounded very edgy, but I didn't believe the removal of paper was the reason, so I was searching somewhere else in my system for the problem. A couple weeks later when I wrapped the 50cm cable again all the problems were gone, the difference was HUGE. Everything was smooth and the brightness had turned into tiny transients! ERS Paper is the best tweak ever! That's why I have wrapped my whole system in it, I have over 100 sheets now.

He sleeps in ERS Paper , which he uses as a sheet on top of his bed, a Select Comfort air mattress, which has a special modded Nordost power cord into his dedicated 20 amp wall outlet, also using ERS paper. WOW! I thought I was tweaked out.

Try porn, it's a much better addiction. For the money you have spent on ERS paper you could get a local stripper to star with you and make your own movie. Call it, Pee Wee We We's Big Top POP.

That movie is already playing at ValhallaPC's home cinema. ValhallaPC owns "over 100 sheets now". He sees a nakes cheerleader under every sheet. Why else do you think he uses so much of this stuff?

Careful now, let's not get this thread closed :) (Of course, if we really wanted to do that, we'd start a new conversation about Diet Coke :))

They need to sell and package that paper by the roll... double-ply and quilted... ;)

Humans are not the correct species for me. I like Valhalla cables more.

That , also , says it all.... (Calling and Shouting) Mark! Mark Rubin!!!???

This thread won't last much longer.

You know why ValhallaPC's ERS paper subjectively works so well for him? Cause he always blows his nose in it, clearing out the crap from his head so he can hear better.

I bought some diet coke with vitamins in it!

Let's not give ValhallaPC too much of a hard time, he serves a very useful purpose as a thread vulture.

He circles high above the forum looking for dying threads. As they are in the last hours of their life he swoops in, picking off pieces of any remaining meat until the thread dies a painful, undignified death to decay and meet its destiny to be buried in the vast archives of AVS.
He then takes off, and soars high above us, fully satiated in his meal.

What I am wondering is how much difference does shielding make? For example, the Motorola Razor that I have already has a metal case, yet adding just a little aluminum foil to the back of the case stops the RF from interfering with the computer. So back to my original question, do higher end cables offer better shielding?

Well, let's turn that around. What vendors provide information regarding shielding such as frequency vs. attenuation plots that you can use to make some sort of decision. Also, in your case Bulldogger, do you know what frequencies the Razor emits? Here, I've had no problems with say a Blackberry or other cell phones such as LG, Samsung, etc.

Well, on cel phones I do think that you cat get emissions ratings from various sources, due to both FCC requirements and the controversies surrounding possible medical consequences of cel phone emissions. As for cables, yeah, I've not seen anything that explicitly documents that info, but I haven't looked for it before, either.

Well, I got this cable for free. I buy and audition gear for an older audiophile buddy. Tired of doing it so as a bribe, he gave me this cable. No way, I would never pay that much for a power cord. It appears to be very well shielded.http://www.psaudio.com/products/xstream_power_plus_sc.asp Ferrite impregnated jacket? Forget about whether is sounds better for a moment. But is the ferrite adding to the shielding?

PS Audio cables work great for computers and video gear because they benefit from shielding the most.

I tried it with my amplifier a year ago and there was less detail than Valhalla. But when I plug in the transport with PS Audio Statement power cable it sounds very good, with the transport it's all about the jitter in different flavors. There isn't any difference in low-level detail unless the flavor of jitter emphasizes something else.


I'm currently using 1m Nordost Valhalla - Ultimate Outlet - 50cm Valhalla - P300 Power Plant (MWave4) - 2m Valhalla - Cary 303/300 CD transport


I heard the same differences when I was using computer instead of Cary, it seems like all power supplies give colored sound from multiwave manipulation.
It seems like the normal Sinewave works best with a stock cable, I'm using it with my computer now and it's more neutral. The added edginess from EMI compensates for the dullness of Sinewave. Multiwaves from the Power Plant add extra detail to the sound, with MWave1 there is more high frequency detail, and with MWave4 there is more low-level detail. MWave1 sounds bright, and MWave4 sounds dark.



Here is my comparison between PS Audio xStream Statement (6awg) and Nordost Valhalla (16awg). I have modified the Valhalla thinner for more low-level detail, and I have added ERS Paper shielding to boost the bass back up.

Statement sounded too heavy which was masking the tiny bass transients. Valhalla seems to add special jitter which makes it sound good.

MWave1 worked best with Statement. MWave4 worked best with Valhalla. Adding opposite colorations gives synergy.

Sinewave seems to work best with stock cable because both are neutral and don't add any coloration.

ROFLMAO. Have you checked out my tweaks thread on using farm animals to treat your listening room? I think you may be pleasantly surprised at what they can do for "yew." :cool:

One thing should be said about VPC... He is unflappable...

ValhallaPC is afraid of your farm animals. That's why he's got ERS paper over all of his ocmponents, to protect it from the droppings and feces from the farm animals.

But is the ferrite adding to the shielding? Probably, but you can never tell with PS Audio. You'll find ferrite impregnation used in certain automotive spark plug wires for the purposes of reducing emissions from the wires themselves. 'Course, it's not the only way to do this. I'm sure everyone at one time has driven and heard their radio punctuated with the stacatto of increasing engine RPM's from a neighboring car.
