Excerpt from 6moons' review of the Walker Audio phonstage :"For example, all wire in the circuit is directional. This is accomplished by replacing a batch of wire in a known circuit and listening to it, then reversing the wire and re-listening. One way will sound better. This is the same wire used in medical surgeries connecting the brain and the ear."
Now what about the surgeon : does he check for directionality of the wire before using it ? If wire directionality were an issue I would think that it was of paramount importance when it comes to this kind of application.

You guys are an education. I enjoy your postings. Conductivity is a great study. But is everything different in the southern hemisphere?I understand that Analysis Plus cable making folks don't care which way their wires are connected, but mark the speaker cable ends directionally for user reference covenience. If true, then there is at least one major brand out there not into directional differences down the length of the wire.
When I changed the direction of my speaker wires last night the musicians on all my cds started to play backwards. Proof that the arrows are not on the wires just for looks. Today I swithced them back, and so far things sound much better.

yes its just a dream...all is good :-)
FWIW the Supra website under technocal questions discusses directionality and other wire properties. Their claims seem rational and are backed up with experiments but it would be interesting to hear what an accomplished scientist would say.

I'm not an accomplished scientist, but I did sleep at a Holiday Inn Express. :)
A couple of comments.
First, they article is based on the false assumption that the wire is drawn unidirectionally. It's not. It's drawn alternately in one direction and then the other, many many times.
In order to draw the wire unidirectionally, you'd have to respool the wire each time it went through the die. In other words, you'd have to run it from one spool, through the die to a second spool, and then respool that second spool onto a third spool and then run that through the die so that the wire always goes through the die in the same direction.
That's simply not how the wire industry does it. Except in Belden's case when Steve Lampen had some wire drawn unidirectionally for the directionality listening tests he conducted some years back.
Second, I'm familiar with the Ben Ducnan article they mention. In it, Duncan was looking for rectifying effects of multiple meteal to metal contacts.
What he did was string a number of connectors together at each end of a length of interconnect and then fed it an amplitude modulated signal. I don't remember offhand what the carrier frequency was (I think it was 1MHz), but the modulating signal was 1kHz.
He then did an FFT looking for the 1kHz signal to show up due to the non-linear rectification caused by the contacts.
He found it I believe at about -150dB.
Anyway, he also made the same measurement with the whole cable and adaptor assembly switched around and was able to show a very slight but consistent difference between the two.
However that difference could have been due smply to a difference in contact resistance between the two arrangements.
Duncan's rather sloppy in his work and seems to be more interested in proving preconcieved beliefs than getting at the truth.
In the Great Cable Shootout they did some time ago, he "discovered" a current-dependent phase shift in the cable measurements he was doing.
LeSerf at Scotts Guide pointed out and documented that this could have simply been due to the fact that Duncan didn't account for the change in load impedance he used to change the operating current for the cable.

Yes, but is the last draw the significent one, with respect to the structur of the material?
or whether it is used on ribbons as well as round wire.
It isn't possible to go from initial billet to final size in one draw.My vendors have required many draws...for supers, they start with about a foot wide billet, and lots and lots of progressive dies...and for silver and copper, same thing...they just start with a smaller billet..
Ribbons? When I have them made, they go through multiple squeezes..
And even then, they require a lubricant.
It would be silly for a vendor to re-spool in between die sizes..
Also would the final draw be the only important issue.At root all of this still begs the question of why wires, even those with no shields, sound different running in one direction rather than the other.
At root all of this still begs the question of why wires, even those with no shields, sound different running in one direction rather than the other.
But at this point we don't really know whether the phenomenon is physical or psychological in nature.
Until we can pin it down to being physical (i.e. an actual audible phenomenn) we'll never get to the bottom of it.
Over on diyAudio.com I tried to establish it as a phyiscal phenomenon by initiating a double blind test. This was rather unique in that it would not have required any switch boxes and the like and the listener would be able to evaluate the cables just as they would under the usual conditions that people purport to hear directionality.
Two participants enlisted for the test.
The first part of the test involved sending each participant some wires whose directions were known so that they could first assess their confidence under sighted conditions as to their ability to detect directionality of the wire.
The first person said they weren't able to hear any directionality, although the same person had previously said that in his experience the wire that was most directional was the higher quality wire and the wire used for the tests was some ultra pure OCC wire that Vampire distributes here in the US.
The second person, who was the most vocal about directionality and how easy it was to hear with any wire up and disappeared shortly after his wires were sent to him and he hasn't been heard from since. It's been nearly a year now.
I've been lately thinking about giving it another go over here.
Would you like to volunteer, Norm?

Many interconnects are shown as directional because of their shields, but in my opinion this is not really a directionality of the wire question.
Does this manu do so from the melt?? If not, what was the process which produced the initial stock that he was able to pull once to final form?Norm: ""
Also would the final draw be the only important issue.""With no real scientific evidence to go by, that question is unanswerable.
Norm: ""At root all of this still begs the question of why wires, even those with no shields, sound different running in one direction rather than the other. ""
Again, with no scientific evidence, there can be no repeatability, no measurement, and absolutely nothing to hang a scientific hat onto to figure out why it would...explanations without solid, real evidence or models is rather useless..kinda like firing a long range cannon without understanding ballistic trajectory...a simple "what comes up must come down" only helps if you drop a rock on ya foot..not hitting a target 20 miles away..
Kinda wish someone could explain exactly the details of the red pill vs the blue one, though...
Thanks.

Their claim is that directionality of power transfer is the reason directionality of wires makes the difference..Hence, the verbage about the power company selling you power..
But the link you post has not a thing approaching a credible justification for directionality. Nada..
Power transfer is simply...current times voltage.. if it is a positive number, the transfer is in one direction..if the product is negative, it is in the oppisite direction..
However, the wires see the current that is being moved, and the incredibly small voltage gradient along it's length, which is simple IR drop.
Each wire does not really see the gradient of voltage that it's partner has...the dielectric does, of course...but not the wire..
So, other than the actual dissipation within the wire (which is very easily measured....the explanation you have linked to does not provide any information...it only appears to be a layman's attempt at bringing in some really good sounding technical verbage to the party..
If they really want to bring grain elongation directionality into the game, they really should learn about the drawing process and it's limitations..like, the lubrication used as the wire is pulled through the die..I've been bitten by that one big time..
Cheers, John
some are more obvious than others.Usually, when the wire is connected in the wrong way, it has a congested and shouty quality to it. ( this is on both speaker and Interconnect cables )

Have you tried flipping around the cables I sent?
I still find it curious that the NANA guys would have said it was directional and put a directional arrow on it when the construction of the cable was such that it couldn't have had any directionality.
For everyone else, the cables are an unshielded quad braid with each pair that makes up the positive and negative legs being made up of wires which came off the spool in opposite directions, i.e. one wire was of one direction and the other of the opposite.
Also, the cable was made from a contiguous length of wire from a single spool.
se
re: flipped the cable around.This is not the first time actually, I've tried with other proto type cables sent to me with no marker. ( I try 'em anyways even tho, I was told they are not directional ) :-)
I am not that interested in scientific explanation. I hear what I hear. And this is repeatable. (at least in my main rig. I haven't tried 'em in another )
No sure whether others really can't hear it, or won't.

"If the only tool you have is a hammer, you tend to see every problem as a nail".
It's a fine line between believing bullshit marketing and keeping an open mind, isn't it?Like another poster, I've tried the Omega Mikro power cords which come in blue and red flavors, the ONLY difference (okay, stated difference) being the direction the cable conductors are oriented in.
Well, you'd have to be deaf not to hear which cord, blue or red, wired forwards or backwards, sounds better on any given component.
Re: directionality, I know Belden doesn't believe in it and has tested it while other cable designers I've interviewed do believe it exists and seem divided merely over whether it's a function of the conductor per se or a function of use, e.g directionality can be "burned into" the cable and reversed with use and further break-in.
Hey, break-in is another one of those subjects. Bel Canto actually measured the difference in break-in on their DAC-2 with high-level equipment and saw a reduction in distortion components after the break-in.
Is wire directionality real? With the Omega Mikro (and if they're truthful about nothing else being different between red and blue cords), it definitely seems to be the case and can be readily verified by listening.
Re: Lloyd Walker's claim, all I can tell you is that it's a ROYAL pain in the arse to test every goddamn wire spool you're getting in. If it didn't make a difference, Walker would simply be a glutton for punishment - and he doesn't sell his wire, he's simply installing it in his circuits so what's in it for him to make empty claims about directionality other than that he considers it an important parameter to check on and control to make his stuff sound its best?
Since audio signals are alternating currents (that flow equally in both directions) I'd really like to have a good explanation as to how a piece of wire that is uniform in its construction throughout its length can ever be "directional" before I believed that this was anything other than the result of an over-active imagination.If the cable is non-uniform in any way, then it certainly could be directional because of a differing response to ambient RF and EM fields.
Every attempt to prove audible differences with the wire identity hidden and volumes matched if necessary over a 25 year period has failed.No audiophile has ever proven to witnesses his ability to hear wires differences among 3-foot interconnects and 10-foot speaker wires intended for audio use.
Many have tried.
I have first-hand experience with double-and single-blind auditions and have watched over a dozen audiophiles fail to hear wire differences. And not just comparing two expensive wires -- but between 14AWG Rat Shack zip cord and a $995 Tara Labs speaker cable ... even after some claimed to hear a difference during a sighted warm-up audition (SPL's matched of course, as the thick Tara Labs cable would play a little louder otherwise).
In fact, audio equipment is just like many consumer products that rely on advertising (to convince consumers there is an audible difference so that consumers will think they hear a difference
when they audition the product)Since most auditions are in audio stores of course there's a difference vs. your home stereo system.
But even if you borrow a component and listen at home, the difference during a single-blind audition will tend to be inaudible or less than it appeared to be during a sighted audition.
I have first-hand experience with over one-dozen sigle-blind comparisons at home (great way to audition audio equipment by the way)
In an AES paper, one audio engineer reported data showing that audiophiles will claim to prefer either "component A" or "component B" approximately 75% of the time ... when in fact there was only one component playing and no sound quality difference was possible !
Therefore it's certainly possible the claim that wires intended for audio use sound different is nothing more than an unproven assertion ... no matter how SURE audiophiles are they just heard a difference during a sighted audition.
In addition, audiophiles have difficulty hearing differences among non-clipping amplifiers and CD players when their identities are hidden.
I also have first-hand experience with double-blind tests of both!
Once again claims of differences in sighted warm-up auditions ... then ears "go bad" when component identities are hidden.
While these tests do not represent what you can hear in your own listening room, they point out how often typical audiophiles claim to hear differences when they know what brand/model component is is use ... compared to when they don't know ... just minutes later.
This happens with many products such as beers and colas and wines --
you're not a bad person if you are swayed by advertising and positive reviews in audio magazine (are there ever negative reviews?) and imagine sound quality differences because you expected to hear them!Anyone still reading: These experiences certainly do not apply to you, so please continue to believe in and enjoy the high-end audio "religion" wher all components sound different ... and you can hear the difference. That belief is good for the ego!
Some cannot understand within the limits of our understanding how there could be a difference and accuse those who do of being delusional. Others say just listen and stop being hidebound by our limited understanding of all the factors affecting sound.
Look in the mirror when you say that.Given the documented subjectivity of individuals' responses to all kinds of things, and the lack of explanation for why a piece of wire would exhibit directional properties when passing a current that moves equally in both directions, why is it not equally likely that an individual's response is not the product of something other than an actual observed phenomenon?
You are in the first group, and I am in the second. Never the twain shall meet.
Norn: ""Some cannot understand within the limits of our understanding how there could be a difference and accuse those who do of being delusional.""
Although I tend to approach everything from a scientific angle, and require proof of explanations, I hope it is understood that I am not one of those..Cheers, John

He he...I try not to think, myself...that way I don't miss the brain cells I'm gonna kill tonight..
I'm not so much interested in putting together a huge system that is sota, finding some recordings which were done correctly, and just sittin there..
But the ideas that pc's, wires, ic's, and such could be audible, when standard theories say they "cannot"...man, that is such a fertile arena for scientific experimentation..
I find it an excellent academic exercise, and it has, in fact, provided some good stuff I've used in my mobile audio forays, as well as for superconducting magnet design and test...
So...color me "open"..I am (somewhat) aware of the limitations of my understandings w/r to science, physics, and e/m theory..
What I suggest is a caricature.I should also note that my undergraduate training was in the natural sciences and my graduate training in the social science. Our theory is really very poor and I am often involved with explaining what is observed with many alternative theories or perhaps a new combination of them. Also as an undergraduate I used to grade lab results and often noticed a normal distribution around the expected results.
obviously you are losing it, all alone in yr little Room.
Taken from Soundstage archives:"On the subject of directionality, Jerry (Jerry Ramsey of Audio Magic) has an opinion which, taken in the context of what all these cable makers have been saying so far, sounds perfectly reasonable even though I had never thought of it that way. He claims -- and extensive listening tests with an experienced panel were used to verify this -- that cables become directional simply through use. He offers that verification of this phenomenon is easily duplicated by anyone interested. All that’s required are cables of truly symmetrical design where the shield construction is identical on both ends. Simply reverse the cables after they’ve been in the system for an extended period of time. Jerry suggests that the sonics will immediately and perceptibly suffer until the cable re-settles in the new direction. This requires another break-in period equal in length to the original one. This process of reversing a cable’s burned-in sonic directionality can be continued ad infinitum. The reason Audio Magic uses directional markers in their symmetrical designs is not to suggest that the cables are delivered directional. It’s simply to remind a customer about which end is which should he rewire his system by swapping components or re-siting his audio rack.
Jerry chuckled reminiscing about the early days when directionally marked cables first hit the scene. Pretty soon consumers acted as though cables without directional arrows on their jackets weren’t high-end any longer. Responding to this trend, a custom of directionalizing cables has taken hold of the industry ever since regardless of the, at least based on this inquiry, overwhelming absence of any available scientific documentation on the subject"
And here's an excert taken from http://www.aes.org/sections/pnw/pnwrecaps/2000/lampen/
"Directionality, or the idea that electricity flows better in one direction through a cable than the other, is a common concept among certain self-identified audiophiles. Belden did a double-blind test for cable directionality in conjunction with an audiophile magazine. The end result was perfectly random. Belden is still happy to manufacture and sell directional cables to enthusiasts. They make up a long length of cable, cut it in segments, identify the ends of the segments so they know how it came off the spool (length A-> B, length B-> C, length C-> D, etc), and then let the customer identify by careful listening which direction is "better". Over thousands of cables sold, the chosen "best" signal flow is random, for segments cut from the same spool! "
I think that we should distinguish between induced and inherent directionality. I believe that the former exists.
beleiving is seeing ;)
According to the laws of physics directionality of cables shouldn't matter. A couple of respected electronic engineers who're also close friends, laughed out loud when I mentioned this a few years back. Personally I never experienced any difference in sound which ever way I connected the wires and the first I heard of such a thing was in one the moronic audio magazines. The article you're referring to is from a Walker table review, Mr. Walker is a major believer of tweaks! I've heard Lloyd's stories about his tone arm wires and his wiring of his motor etc., what can I say this is over priced audio in 21st century were people still believe in the black arts.
Engineering is trying to apply what we know to problems and then adding a safety factor in case we don't know enough. Rules of thumb rather than laws of physics would be more accurate. All I can say with any confidence is that the Omega Mikro power cords which differ only in the direction of the wire draw sound very different on many components.
I agree with you as far as power cords go, Omega Mikro or anything else, they do affect the sound and there's no real convincing explanation why that I've heard, but that's still very different than directionality of wires affecting sound.
a
I heard a difference from almost all the power cords I tested, mostly distortion (hifi coloration?) and the Mikros were nothing unique. In fact I preferred some cheaper inexpensive industrial grade pcs to most of the expensive audiophile versions that I tried.

Well, to me at least....Need more details...more than can be put on a subject line..
Config at either end..
Are the internal wires color coded?
Is the cord hot/ground/neutral spacing/order exactly the same.
Are the center to center spacings the same..
I know they are ribbons and supposedly the construction is identical save for one having the wire pull run from the wall to the component on the hot and the opposite on the neutral. The other reverses this. They do sound different. I do not know how they are insulated, but I doubt they are color coded.
Thanks..walker's site does not specify any details, but only says that one will sound better..The explanation you've provided, which I accept as what you are told or are aware of, does not make any sense, I realize you are the messenger.....it implies that an AC current knows which way the outlet is, and can decide through some unknown mechanism, which direction to be nicer w/r to the lectrons...
Without more construction details, I fear we are all pissin in the wind...is ground in the middle, one side, is it next to the hot??. Now those questions are extremely relevant to ground loop coupling..
Cheers and thanks, John
I once even went to the trouble to separate a cheap two wire power cord. I reversed on wire and cut it in two. I then reterminated one with the wall plug at one end and the other with it at the other end. I then tested whether I could hear a difference. It was not as audible as with the Omega Mikro, but it was clearly different sounding.I think Omega Mikros further argument is that the wire in a component's ac transformer is drawn in one direction and that what you are doing is matching that draw. This then brings into question whether transformer manufacturers pay any attention to having the same draw for all windings.
Norm : ""I once even went to the trouble to separate a cheap two wire power cord. I reversed on wire and cut it in two.

Norm...you changed the hot to neutral capacitance, the inductance of the cord, it's susceptibility to RFI, it's impedance across the entire spectrum, and the strength of the dipole field it broadcasts for 60, 180, 300hz and up, all haversine components of the supply, as well as any coupling of audio signals and bridge rectifier (solid state of course) reverse recovery transients, as well as the integrated time rate of change flux which occurs between components and the interconnects which connect them...Other than those small items, your experiment was well controlled..
(my apologies for that last bit...it's end of the day, and I have off tomorrow, so I'm chompin the bit to drown some olives...)
Your experiment, while well meaning and really interesting, points out that in addition to the change you intended to test, there is a huge list of confounding changes you did not have control over that could alter the outcome of the experiment..Man, I can't wait till my basement lab is setup...
That about sums up my take. I am still recovering from the capacitor discussions over at the mad board. About 100 audiophiles could not hear a difference between a $20 and $0.20 cap. Yet this guy hears wire direction. I am deefer than I thooght.But wait! there is more! I am a manufacturing guy by trade and the idea of putting together an electronic unit to test it, then disassemble it to change it, on every piece! Nuts.
Also, surely there is more that one wire in the unit. So what if 5 are the right way and 14 are the wrong way? Can he (she) hear that too?
Lastly, do wires connect the brain and the ear in surgeries? Does this mean I can wire my mouth to my hand and speak with my fingers? What about the sexual implications of rewiring my body, or better yet, my wife's?
You can get bounced out of here with that kind of attitude! Don't you realized that EVERY tweak or wire upgrade (price-wise anyway) results in dramatic improvements in sound quality? Have you ever heard of an expensive tweak that didn't? Wire IS directional. Just ask the electrons.
I am about to patent an "electron spa", a small device where electrons can gather and enjoy life a little before being rushed into service. They will only be yanked out of the spa if they are really needed and then only in groups :)About 2342374 years ago, I had a girlfriend whose father ran the cycletron at Berkeley. One day he gave us a really cool tour of the place. Three things really stood out for me.
First the evidence of "when electrons go bad", that is, laser-like slices through 4-5" 500 lb metal inductors when the magnetic field did not hold.Second, all the little notes taped to the machines and sometimes the floor "don't stand here ever", don't stand here for more than 5 seconds", "don't go over there if you are pregnant", "don't dawdle in this doorway", "do not stop walking in this hallway". Scary stuff.
Third, how he talked about electrons like they were people. "first we gather them on this plate and they get all happy, then suprise them with XX kilowatts and they run away down this tube. Just when they start to get tired, we shoot another XX kilowatts at them and they (he raises his hand and goes "ieeee") they take off further down the tube."
It was pretty cool.
And even my wife could hear the difference.

Is the listed site selling you a product?Id take a look at loudspeakers/room acoustics first.
Try it and see!Move your head 1/8th of an inch to hear a magnitude more distortion due to varying reflected room reflection.
I've made half a dozen power cables for those components of mine with IEC jacks, cutting up and reterminating the Home Depot 14 gauge outdoor extension cord ("HD-14") discussed in the Cable Asylum. First one I made sounded not as good as the stock power cord or aftermarket PCs, until I reversed it end for end. I couldn't believe it either. Don't dismiss this until you try it (under 20 bucks for a 50-footer makes it a pretty painless exercise).
What you did altered the geometry of the hot/ground/neutral as well.
Why do you think that didn't matter? In essence, you did not account for a confounding influence, but yet assign the effect to the actual metal conductivity "preference", one which does not have it's basis in any physical model or theory..I would address the blatent system changes that resulted from your end to end swap first, rather than pushing an explanation that defies all known physical laws..
When one rules out the major differences you created by swapping ends, then one can start to think about physics beyond that which is known..
Cheers, John
changing directions changes the sound - geometry - whatever? If it sounds better one way than the other THAT'S the way to use it. Simple enough eh?
"If the only tool you have is a hammer, you tend to see every problem as a nail".
Unless, of course, you prefer to wander about the corridors aimlessly for decades, using random turns to guide you....as opposed to looking up, and seeing the sign pointing to the exit..That's been my biggest complaint about "high end" in general...all random...random fixes, random tweaks, random explanations for a random tweak producing a difference...
For the bulk of society, you are correct...nobody knows, nobody cares...turn the damn key, it goes...if it don't, "it bwoken"...
Same with computers...nobody cares about the low level machine code within the cpu....they just need it to work...period. If it's "bwoken", call in da guy who "UN-BWEAKS" it...
That is not me...If the reason can be found, a solution will follow..
I refuse to accept "well, it works"....If someone wants to believe that the reason it sounds better is because the tape on the cord is blue instead of red, fine...let them.. soon, a cottage industry in blue tape will crop up...along with a "blue tape asylum".
Unfortunately, it does nothing to advance the state of the art..
Of course it would be ideal if all these things could be explained.
Something as basic as gravity is not understood by science as yet.
Under these circumstances, we have no choice but to trust the evidence of our own hearing.
Furthermore, we all have systems of vastly different resolving capabilities to say nothing of varying hearing acumen.
I have no doubt that on many systems the differences may be minimal, on others quite obvious.
Agreed completely - up until the "blue tape" part. But I'm not going to become an expert on the transmission of current before I try changing the direction of a cable - especially, when someone else who has tried it tells me that this particular cable is directional. A la HD-14. Especially when it costs absolutely nothing to try it.Just as smarter people than I developed software - I left it to THEM to figure out how to make a computer do what I WANT it to do. Little point in re-inventing the wheel.
Your point on "random" tweaks is, however, very well put.
"If the only tool you have is a hammer, you tend to see every problem as a nail".
Dave: ""Agreed completely - up until the "blue tape" part.""
No, you even agree with that, but I should have added a little more verbage.....what I meant by the blue tape part was not an argument about whether or not omega micron blue vs red style made a difference...what I was alluding to was that without any other information to go by, there will be people who will explain at length why the color blue is having the effect..I also wonder it that manu would be willing to try putting blue and red 50-50 on cables, so that they could see if there is a true correlation between the color put on, or if it is truly determined by which way they made the wire...
Dave: "" But I'm not going to become an expert on the transmission of current before I try changing the direction of a cable - especially, when someone else who has tried it tells me that this particular cable is directional.""
I would never ask anyone to do that..the role of engineering is to make it possible for all to use the technology..not to have everybody understand it..nobody has to know how the car works..and many don't care..they just want to go..just like tire designators...V, H...who cares...just give me some tires...
The blue and red bands on the outside of the Omega Mikro AC plugs are just there to distinguish one from another by sight. When buying this PC new, the buyer actually receives TWO PCs (yes, with red and blue ends) and tries them both out on whatever link they want the PC for. The "right" one is obvious, or it was to me. I have used these PCs and you'd have to be pretty deaf not to be able to tell which one sounds better (in the specific link). It's just as Kuma noted above.

I was commenting only on the last sentence of the preceding post. I have no idea why these PC s sound different (and you only managed to further confuse poor technically-illiterate me) depending on their direction. And, sorry, but I still don't :-)
Dave: ""I was commenting only on the last sentence of the preceding post.""
I know.Dave: ""I have no idea why these PC s sound different (and you only managed to further confuse poor technically-illiterate me) depending on their direction.""
The content of the last couple of posts was on the directionality of wires, which it has been contended, is a result of something in the structure of the metals. You know, the old "drawing direction" kind of stuff.And your example of a line cord, with it's "direction" changed, changes something else besides which end of the cord is at the wall, and which end is at the amp..
