"Yes, the signal is different, audibly different wrt the cables' direction. By the way, I actually answered that question already, at least once. The signal in the cables is different; therefore, the acoustic waveform generated by the speakers is also different. That's why directionality is audible. Shall I draw you a picture? "
Nope, an actual change in the signal or in a speakers response i can deal with / measure, that's my job.
Follow Ups:
"Yes, the signal is different, audibly different wrt the cables' direction."
geoffkait made a claim but then says he doesn't have to prove it. It is true no one can make him establish it, but he still has the burden of proof. He evidently has no intention of meeting it.
For practical purposes, I ignore the issue for audio cables direction, since no one seems to have established that makes an audible difference. If geoffkait or someone else wants to establish that changing the direction of the cables makes an audible difference, more power to them. But I don't see a reason to buy fancy wire except for show.

Prove me wrong. There is no burden of proof on me. Don't shoot me, I'm just the messenger. I did not create reality. My job is to reveal reality. Break free from your reality tunnel. See the world as it is not as you believe it is.You actually don't want me to prove anything. What you're really looking for is some way to independently verify and validate wire directionality, isn't it?

It's a matter of perspective, a story about the philosopher Wittgenstein and a student illustrates the situation.
The two were watching the sunrise and the student posed how stupid they were in the past when they thought the sun went around the earth.
After a short silence Wittgenstein said Yes...but what would it look like if the sun did go around the earth?
His point being it would look the same and the only difference is now "we know" what really happens.
Speaker cables all have (in decreasing order of effect) a series R, a series L and a parallel C, dielectric absorption, all of which can be measured.
Modern passive crossover design involves having the driver impedance curve and frequency response to work with, one can add in what ever cable properties you with.
One can (and i have) used a Null bridge to "listen to" the signal difference from one end to the other and in a different area designed a transformers and 1 turn coil, where one could pass 300Amps at 12 MHz for levitating glass.
The point is, your experiences have lead you to conclude something anomalous based on my experience working with the details, we come from different perspectives.
Don't get me wrong, there ARE plenty of things not understood in audio but for me the magic and discovery are in what properties makes loudspeakers disappear in a phantom stereo image and what things make them stand out as obvious sources.
No, it's not at all like that. It's just a reality you are just being stubborn about accepting. It's the same thing as a lot of preposterous sounding ideas in this audio hobby. Since you have no experience in directionality you can hardly make an argument based on experience. A real skeptic, a real scientist, would roll up his sleeves and try to see what this directionality business is all about.While you may attempt to mystify it, directionality is explainable, predictable, audible, repeatable and transferrable. In other words it's scientific.
This audio hobby has a colorful history of things that have confounded audiophiles ever since audio feet and fancy cables reared their heads - CD treatments, cryogenic treatment of cables, electronics, tubes, CDs, LPs. Also fancy fuses, micro-arcing, contact enhancers, silver rainbow foil, cream electret, Mpingo discs, Schumann frequency generator, demagnetizing CDs, colorizing CDs, the Tice Clock, the Clever little clock (battery powered), tube dampers, tiny little bowl acoustic resonators.

"No, it's not at all like that. It's just a reality you are just being stubborn about accepting." " A real skeptic, a real scientist, would roll up his sleeves and try to see what this directionality business is all about."
That encapsulates the error in your assumption.
You assume i have not looked at this, have not done null tests with speaker cables with music, have not had to make things work regardless of the operators mindset.
The last sentence may apply here as there is a whole category of "audio accessories" which the purchasers say have a positive effect and yet the same devices are often inaudible when the listener doesn't also know which cable or knob or what ever change has been made (aka blind).
These things tend to be harmless functionally speaking but have an exotic story, cost more than one would expect and reminds me of go-fast aftermarket car parts from a 1970's catalogue. Yes a chrome air filter cover is smoother aerodynamically but it doesn't actually increase HP.
For sure, if you make a change that people without prior knowledge identify above the "odds" as better then you have an improvement, if that impression holds with different kinds of music and tastes, that is a real improvement.
Now,none of this really matters in the home exactly what improves the listening experience as BOTH what enters your two ear holes AND what you know AND see is what makes up our conscious "3D hearing experience".
It matters most if your designing speakers that others will use where they don't know what was involved and you didn't know what type of music they will play.

I have basically argued that for years. The problem is that I don't take the word of geoffkait and other audiophiles for it that cable direction and lots of other unproven tweaks make an audible difference. But my advice is to get what you like.
But they want to spend a lot of money and trouble on unproven tweaks, it's their time and money. But that doesn't seem to be good enough for geoffkait and some others. I still buy what I like.

It's what you choose to believe and it makes you feel good. That's what all the pseudo scientists say.
I'm sure you haven't looked at this, not in a serious way. Otherwise, we'd agree. Everyone in the world who's looked at this directionality thing *seriously* is in agreement - all except you and some other naysayers. You/they have strong maybe too strong belief in science, strong belief in controlled blind testing, strong aversion to anything that remotely looks like snake oil. Blinded by science. I have more science and testing than you, I hope I can be so bold to say that. All or most of 100,000 or whatever number of customers who bought fancy audiophile fuses of various brands found out about directionality. Think of directionality like black holes, you can't see them directly, only indirectly.

Hi
I would offer a couple comments on your last post;
"I'm sure you haven't looked at this, not in a serious way.
Otherwise, we'd agree. Everyone in the world who's looked at this directionality thing *seriously* is in agreement "
Interesting proposition, the logical counterpart of the old saying "when everyone agrees, no one is thinking very deeply".
"You/they have strong maybe too strong belief in science, strong belief in controlled blind testing, strong aversion to anything that remotely looks like snake oil."
I have watched the hifi area go from a scientific endeavor at the hands of folks like Dick Heyser, into a market where there are many examples of things that are psychological only in effect and so are undetectable in blind testing. The "snake oil" products have made "hifi" an area too many discredit.
The blizzard of "marketing the idea of science and progress" is how people can be amazed by ancient loudspeakers and amplifiers that can still sound remarkably good, actual improvements (which are widely heard in a blind test) are slow and few.
"I have more science and testing than you, I hope I can be so bold to say that."
Well obviously you are so bold, but based on what you have said here, i would bet that's also not true .
It always comes down to your arguments, it must be psychological, it disobeys science, it can't be detected in a blind test. All of these arguments are the stick in trade of the earnest pseudo skeptic. I'm afraid as much as I've enjoyed our discussion this particular thread can serve no purpose any more. Science used embrace curiosity and investigation but now it's become like religion, narcissistic and unwilling to change.
"It always comes down to your arguments, it must be psychological, it disobeys science, it can't be detected in a blind test. "
Your ability to dance around the fact that what one hears is partly what you know and see is remarkable, have you ever thought about why medical hearing tests never include a little red light to tell you when the tone is present or why the person running the test can't give you clues? This only tests your ability to detect the sound yes or no, not what you know or think or see. The ONLY way to determine exactly what you hear is when you remove all the "non-auditory" information.
While you may think of blind testing akin to a gruesome non-reversible medical procedure, it simple means what you see and know tells you nothing about which of two cases you are hearing.
The fact that when you spend money on an aftermarket trinket, that this in it self is a powerful motivator to hear an improvement IS psychological , have you ever wondered why often what was a dramatic improvement with a new cable, diminishes to slight or undetectable when tested blind?
That last part is where i became interested, i have built loudspeakers my whole life (well i made the first cabinet in 7th grade) and have a company with my name on it now. While the easiest place to grow with a new technology was was in commercial sound where large scale sound is the most difficult, my interest has been hifi since i heard sound coming from a heathkit speaker at my grampa's.
I pressed you for details because the psychology is powerful, if you spent a lot of time or money on building new speakers, you are incredibly inclined to hear the good in it.....and ignore the bad, maybe even shape your choice of music around what sounded good.
All that is fine if they are your speakers but when you have to design speakers for other peoples choice of music and situations, one has to focus on the things that are universal and audible as an improvement in a blind test or side by side with other choices.
You said "Science used embrace curiosity and investigation", someone on line made a Wiki entry for me which is reasonably accurate, does what you said describe what i do as an inventor?
https://en.wikipedia.org/wiki/Tom_Danley
Any test including a carefully controlled blind test can have problems, including undetected ones. There are lots of reasons why a test can have negative results, even when the tester is very thorough and has lots of experience. But what does have meaning are the cumulative results of many tests in many different systems by different listeners.
No need to blow your own horn here, we appreciate what an Appeal to Authority is. If credentials or experience were capable of winning arguments then any yutz on the street could simply claim, "I have 40 years of experience in this hobby therefore I must be right." That pretty well sums up your arguments in the present discussion.
"No need to blow your own horn here, we appreciate what an Appeal to Authority is"
The reason i mentioned my background at the end of the conversation rather then the beginning was to illustrate that while i began as a DIY'r, most of my life turned into doing R&D in areas where there were no solutions and my job some of the time was developing new things and new types of transducers, for example these;

"Any test including a carefully controlled blind test can have problems, including undetected ones. There are lots of reasons why a test can have negative results, even when the tester is very thorough and has lots of experience."
Absolutely true, just like medical or other tests, our difference seems to be that you discount what measurements and controlled testing CAN tell you.
You seem to totally gloss over the FACT that what we perceive is partly what we know, see and believe as well as the sound going into the holes on the sides of your head and are unaware of (or is it depend on?) the power of placebo even in audio.
Do you actually design anything technical or just market stuff or do you want to end this here?
We've already talked about this education and experience obsession of yours a couple of times. Apparently you have run completely out of ammo. If you can't come up with any evidence to support your position I hereby declare myself the winner. You cannot win the argument by constantly challenging my experience and education. Which, as it happens, I'm quite confident is superior to yours.
Beyond using #12 gauge wires, speaker wires makes no difference. RCA high impedance wires do make a slight difference. I use Bluejeans low capacitance.
I'm way ahead of you. You have drawn the wrong conclusions. Better luck in the future.
Speaker wires are low impedance, higher voltage and short in length as compared to phono wires. I hear a minor difference in phono wires and not sure if the capacitance plays a larger factor. As for speaker wires of about 14ga in pure copper, I think the placebo effect is larger than the different speaker cables true sound effect.
Try reversing the direction of speaker cables sometime. That should be pretty obvious.Limitations in any audio system can sometimes limit that system's ability to reveal what's going on with cables. Negative results can be misleading. Testing for differences in audio are not at all like taste tests or pharmaceutical tests in that there is an entire system in audio tests between the thing being tested and the listener. A lot of things can go wrong. In audio tests it's probably never placebo, always an error in the system somewhere.

Very funny, but you must be looking in the mirror, Mr. pseudo scientist.
IMO speakers are such low impedance and runs are short the wire is not critical. #14 or #12 gauge should perform fine with copper conductor wire. I use zip cord.
That's not the issue here on this thread.Type of wire, gauge of wire, quality of wire, cost of wire are separate issues from the subject of this thread. Directionality is independent of those other factors. Now the metal lead as a conductor material might be interesting since it's not directional.

The most used argument used by skeptics and pseudo skeptics is if the fuse is in an AC circuit how can it be directional since the signal goes both ways? Same logic applies to cables and power cords since they're in AC circuits, too.
Edits: 11/13/22
I asked you if the directionality you hear was a result of a change in what's arriving at the loudspeaker terminals.
I asked because part of our hearing is also what we see and know and so, while building a loudspeaker or amplifier with exotic hifi parts those WILL give the builder a better listening impression when finished (even for me) and for the most part, those kinds of improvements won't be measured, noticed or heard by a someone who didn't know of those mods and so has to be told of them first.
Scoff at the idea of blind testing if you will but if you can't hear the difference between two things like speaker cables switching back and forth without knowing which was which , how much of that impression is actually based on hearing?
There are a number of examples like the "McGurke effect" which show for instance your brain will choose what you see over what you actually hear, even when you know what's happening (google it and try)..
The problem is designing a speaker product others will use, there are so many actual acoustic and electronic things actually going on and your brain seeks information and rejects noise, so that loudspeaker development by ear only reaches a point where changes make some recordings better and others worse.
It is difficult to make a speaker that is neutral, harder yet so that it disappears into the phantom image and not be part of the image..
So let me help you out, for a moment pretend you had worked in electronics and sound for the last 40+ years, building measuring and researching new things and were responsible for about 30 patents.
And that you had an open enough mind enough to figure out how to levitate and melt glass with magnetic fields, how to levitate an object with sound at 1600 degrees C, designed the transducers and circuitry to do all that and built several experiments that flew on sounding rockets and the space shuttle.
Further pretend you had been fascinated with "how things work" and especially loudspeakers since childhood and had been building both drivers and speaker cabinets since 8th grade.
Perhaps you might ask questions like i did should someone tell you there is a whole world of audible electrical phenomena that was not observed in any other field outside high end hifi.
While i never observed anything like directionality in cables (outside of the cable factors i outlined) , i have observed a connection between what can be seen in some kinds of measurements and what random strangers hear.
I have observed objectively that when you make a generation loss recording with loudspeakers, that the more generations a loudspeaker or electronics can reproduce and still be listenable, the better most people will think it sounds with any kind of music and the better demonstrations go.
To not be fooled by expectation bias, one needs both subjective and objective observation and knowledge to have a stool to design from. Clearly you have an unusually strong belief, what is your objective background in this area ?
You wrote,"To not be fooled by expectation bias, one needs both subjective and objective observation and knowledge to have a stool to design from. Clearly you have an unusually strong belief, what is your objective background in this area ?"
You make it sound like a religious argument, when it's actually a scientific argument. You haven't found anything to support the idea of cable directionality. You have mistakenly assumed cable directionality applies to areas other than HiFi. You have assumed you are a real skeptic therefore you must be right. These are all logical fallacy arguments on your part, mostly of the type Appeal to Authority and Appeal to Experience. If all PhDs thought alike then any PhD could say I have a PhD, therefore I win the argument, no? But all PhDs don't think alike.

"You make it sound like a religious argument, when it's actually a scientific argument."
Is it that the "breakthroughs" are so new that credible peer review groups have yet to process this information or is it that there has been plenty of time for that to happen and no credible peer groups seem to be echoing your result?
Surely what applies in hifi would also apply in pro audio and therefore this information, if it really exists, would have importance outside of tweak circles.

The problem is your claim of it being a scientific argument when there is little/no evidence suggesting it meets the standards. The claim implies the accepted scientific principles are being adhered to: (1) Pose significant questions that can be investigated empirically; (2) Link research to theory; (3) Use methods that permit direct investigation of questions; (4) Provide coherent chain of rigorous reasoning; (5) Replicate and generalize; and (6) Transparency and scholarly debate.
When/where is the evidence any of this research/experiment/debate has occured surrounding cable directionality questions?
Let us know when you've finished your research and report your results. I can hardly wait. It's actually not my job to provide evidence. Keep looking, have you contacted NASA or IEEE? Maybe they can help you.
Edits: 11/16/22
I'm not the one making the claims then calling them scientific.
It's not up to me to prove anything or even to provide evidence. Which I have already, you just refuse to listen. If you're curious and believe in the scientific method, which you probably don't, you investigate the claim yourself. Or you hire an outside independent third party to verify and validate the claims. Is not observation part of the scientific method? I saw an Apple fall from the tree. That sort of thing.Here's a challenge for you. Prove that directionality doesn't exist.
Edits: 11/17/22
Normally, if one proposes something "new to science" it is the duty of those proposing to show proof it exists. As they say, extraordinary claims require extraordinary proof.
That there is a directional effect in speaker cables is such a claim but lacks anything like "engineering proof" that you can point to other than some people say they can hear it.
Some people say a lot of things, here, most likely "if you can't hear it, your system doesn't have enough resolution" or other cop out.
Meanwhile the fact it is only folks associated with the audio aftermarket biz that seem to promote this idea, that there is no attempt to show and engineering explanation, leaves many rightfully skeptical and some going to great lengths to promote it.
I'm not proposing something new to science, as you say. Whatever gave you that idea? Do you consider yourself informed of everything in science, is the real question. I'm beginning to think so.I am under no obligation to present engineering proof, as you say, or proof of any kind or even evidence. This is not a peer review forum, in case you haven't heard.
By the way, I never said directionality is real because some people claim to hear it. Why do you insist on putting words in my mouth? (You are very adept at using pseudo skeptic arguments.)
Because systems can sometimes have errors and peoples' listening skills are often unreliable, negative results of a test for directionality are meaningless. Even if the test is a controlled blind test. Meaningful results start to emerge after many tests on many systems with many test subjects. Repeatability and transferability are the key.
You keep trying to argue that only niche audiophiles are concerned about directionality. That's true but it doesn't mean it's not real. You can follow that logic, right? That's another pseudo skeptic argument.

"Because systems can sometimes have errors and peoples' listening skills are often unreliable, negative results of a test for directionality are meaningless."
It is the exact same reason to be skeptical of positive results, or if you really believe in cable directionality, the ability of a manufacturer to deliver the products to the customer consistently without any case of somehow confusing the customer into installing them backwards.... mislabelled cable direction indicator per manufacturing defect as an example.
"Meaningful results start to emerge after many tests on many systems with many test subjects. Repeatability and transferability are the key."
There seems to be some logical flaw in the following line of reasoning: "listening skills are often unreliable", and yet the proposed method of detecting the effect, ie (paraphrasing) "just listen myself and see if I like one direction better than the other".
There are at least two conductors per interconnect per channel. However the only thing most of us would consider practical is multistrand not solid core. That is a ton of book keeping just to get one cable built correctly with out any mistakes. It's hard to imagine how all this overhead wouldn't be prohibitively expensive for a boutique audiophile manufacturer to control. And really begs the question why bother doing the listening test on any old manufacturers multistrand cables with presumably random distributions of strands within the multistrand bundles pointing in one direction or the other.
No, positive results are not the same as negative results. Negative results from a single test have no meaning. That's because too many things can and do go wrong with tests. But positive results are meaningful because they were positive *in spite of* the many possible pitfalls.What are those pitfalls, you ask. Fair enough, here is a short list,
1. Error(s) in the test system, including but not limited to, speakers wired out of phase, cabling connected out of phase, absolute polarity of system inverted, cables or electronics not broken in sufficiently. These error would potentially mask differences in sound.
2. Test system lacks adequate resolution for task at hand, making the sound differences impossible to detect.
3. Listener not sufficiently skilled at detecting differences in sound.
4. Listener doesn't know what differences in the sound to look for. What difference in sound does directionality produce?
5. Test procedures not followed.
6. Listener might be biased against the test item(s). He could be strongly anti tweak and nit admit to any Sonic differences if there are any.
One person's listening skill might not be up to the level of someone else's. If you don't know what directionality sounds like you might not hear it the first time around. That's what I meant by listener skill being unreliable. You can't drag some guy in off the street and expect him to hear directionality.
It's not difficult to control any wire or cable for directionality. You must "control" the wire as soon as it comes off the spool, every length of wire after that is in the direction. AudioQuest (and others) has been doing this for many years uh, 25, so obviously it's not prohibitively expensive, as you say.
For fuses, the wire doesn't have to be controlled during manufacture since it's easy to reverse the fuse in its holder and decide which way sounds best.
Finally, in an AC circuit there are two wires, one carries the electrical signal in one direction while the electrical signal travel in the opposite direction at the same time. The signals alternate direction on each wire according to the instantaneous audio frequency.

Directionality: It's All About Noise
07.01.16
If you've ever wondered about the arrows on AudioQuest cables, read any of our educational materials, or merely followed any of the online chatter regarding our products, perhaps you've wondered what this "directionality" thing is all about.
There is the widely accepted version of directionality: In most audio-grade shielded interconnects, as compared to standard coax, negative has its own internal conductor and the metal shield is attached to ground at only one end, thus defining the cable's directionality. Many cable manufacturers end their exploration of directionality there, going only as far as to mark their cables for directionality based on the relationship of shield to ground, but altogether neglecting conductor directionality. Because we believe in directing noise to where it can do the least harm, we, too, believe in the advantages of controlling for the attachment of the shield. In fact, long before we controlled for conductor directionality, AudioQuest interconnects were also controlled for direction based on the relationship of shield to ground.
Over the years, our understanding of conductor directionality and its effect on audio performance has steadily evolved, growing stronger and more complete. While we've always been keenly aware that directionality plays a significant role in the overall sound of any hi-fi system, we couldn't completely explain it. This was okay: We trust our own ears and encourage listeners to do the same. The test is easy enough: Simply listen, then reverse the direction of the cable, and listen again.
I think your confusing what i was questioning with someone else i guess, i was very specific speaker cables and NOT small signal cables.
Rarely does one find an engineering approach where being skeptical is a bad thing, i find this discussion curious.
"Over the years, our understanding of conductor directionality and its effect on audio performance has steadily evolved, growing stronger and more complete."
Yes i get that impression from you and that there is a collective "our" somewhere too, it's just normally there is something in the objective world that indicates or suggests a mechanism for an actual change.
What does it look like when doing a google search on this subject, it would seem the only folks spending money to advertise or write about it are companies associated with hifi aftermarket.
Search any other topic about electronics engineering like skin effect or propagation velocity you you have many engineering hits.
I've already revealed the mechanism for the change in sound. Must be a mental block. This is what is commonly referred to as the backfire effect. When confronted with evidence to the contrary of strongly held beliefs or opinions a person clutches those beliefs even more tightly. We even have a name for it.Yes, there's a collective out there. It's a collective of advanced audiophiles, like the 140,000 who have bought directional fuses. Get on board the directionality train, toot, toot!
I did not say being skeptical is a bad thing, please don't put words in my mouth. That's another logical fallacy strike for you. What I'm saying is being falsely skeptical is bad, pretending to be scientifically skeptical but not really willing to do the leg work. We call them pseudo skeptics.
You wrote,
"What does it look like when doing a google search on this subject, it would seem the only folks spending money to advertise or write about it are companies associated with hifi aftermarket."
That's so funny you should say that because this entire discussion has been about directionality of cables and wire in audio systems. The concept doesn't exist outside of HiFi. Directionality is a HiFi word. Hel-loo!

It's not like I'm saying I've seen flying saucers. It's also not like I'm the only one who has heard directionality. AudioQuest identified directionality 25 years ago and developed perhaps the best way to control directionality during cable manufacturing. Don't shoot me I'm just the messenger. A part of why more than 120,000 audiophile fuses have been sold is because the issue of directionality is part of the fuse mystique, so to speak. Even an old stock fuse tgats been in the system for 10 years will sound sound better or worse if you reverse it in the fuse holder. What have you got to lose? I dare you.

You keep saying nope. That's what pseudo skeptics always say. No, it can't be. No, it can't be measured. No, it disobeys the laws of science. All of the rules of wire and cable directionality can be derived from the mysterious case of the tiny little fuse. A mere 1/2 inch long piece of very thin wire makes an audible difference which way it's inserted into the fuse holder? Doesn't seem possible, does it?
HiFi Tuning in Germany used to have data sheets of fuse measurements on their web site, but the data sheets may have finally been removed, new management, who knows, a more shall we say conservative management. But they were there for many years. What the data sheets showed was the difference in voltage drop across a number of different fuses, including HiFi Tuning, stock fuses, both cryogenically treat and untreated. The fuses were measured in both directions. The results showed there was a slightly lower voltage drop across fuses when they were inserted in the "right direction" - slight but measurable and all fuses exhibited this difference in voltage drop. Stock fuses are directional just like audiophile fuses.
So, now for the $64,000 question, if fuses are directional doesn't that mean all wire is directional? And if all wire is directional shouldn't designers of electronics and cables and fuses control the directionality of EVERYTHING? Hel-loo people! Is anybody listening? I mean unless everybody wants to rest on his laurels and is happy with the status quo.
