What do we hear when we change the direction of a wire?


Douglas Self wrote a devastating article about audio anomalies back in 1988. With all the necessary knowledge and measuring tools, he did not detect any supposedly audible changes in the electrical signal. Self and his colleagues were sure that they had proved the absence of anomalies in audio, but over the past 30 years, audio anomalies have not disappeared anywhere, at the same time the authority of science in the field of audio has increasingly become questioned. It's hard to believe, but science still cannot clearly answer the question of what electricity is and what sound is! (see article by A.J.Essien).

For your information: to make sure that no potentially audible changes in the electrical signal occur when we apply any "audio magic" to our gear, no super equipment is needed. The smallest step-change in amplitude that can be detected by ear is about 0.3dB for a pure tone. In more realistic situations it is 0.5 to 1.0dB'". This is about a 10% change. (Harris J.D.). At medium volume, the voltage amplitude at the output of the amplifier is approximately 10 volts, which means that the smallest audible difference in sound will be noticeable when the output voltage changes to 1 volt. Such an error is impossible not to notice even using a conventional voltmeter, but Self and his colleagues performed much more accurate measurements, including ones made directly on the music signal using Baxandall subtraction technique - they found no error even at this highest level.

As a result, we are faced with an apparently unsolvable problem: those of us who do not hear the sound of wires, relying on the authority of scientists, claim that audio anomalies are BS. However, people who confidently perceive this component of sound are forced to make another, the only possible conclusion in this situation: the electrical and acoustic signals contain some additional signal(s) that are still unknown to science, and which we perceive with a certain sixth sense.

If there are no electrical changes in the signal, then there are no acoustic changes, respectively, hearing does not participate in the perception of anomalies. What other options can there be?

Honest mistake.   See not so hard to admit that.   It's cold out but a few chill pills can never hurt.  Cheers!
Maghister I think you need a vacation. I was not quoting nor even talking to you. Take a chill pill or two.
The one thing human perception is not, is accurate.



Marketing is the tool used to address those pesky human perceptions.

For example, you can can be a total unknown and sell a wire for $10K. Then you can give a skeptic permission to buy it and find out how wonderful it is. THen when he declines, call him a coward. Works every time!

Don’t forget to give a few away to a few cohorts so they can write up rave reviews all on a free hifi web site that sells expensive stuff. That helps keep the marketing costs down.


Using it, you can evaluate the coloration and right direction of almost any radio component (L,C,R) including wire.

Ok now we are getting somewhere. Have you done that? Where are the results published for those who might be interested?


I would believe whatever differences there are would show up most in cases where there is an impedance mismatch which is much more likely with zero feedback amps, but that should not really matter if one has addressed impedance matching between amps and speakers properly, which is the right way to do it for best results, so in that case impedance matching issues due to a zero feedback amp is a moot point.   


But still, most of the claims are made by very specific people, i.e. manufacturers, who claim the difference is obvious and significant.

...yet often don’t bother to tell you which is the right direction in the manual. Yes any sophisticated device that cost a lot of money can be expected to come with a manual that tells you how to properly use it. Mark the direction on the wire and reference it in the manual to leave no doubt. OR maybe they don’t really know either but say they do? That’s dishonest. Even for a wire. How can you trust a company that forgets to document such an important thing as the correct direction of their directional wire?  Or worse yet outright lies to you?   Much less pay them big bucks for it?

Oh well its a free country. Do it if you must.

My first question in order to be able to anser tht one would be which wire specifically are we talking about? There are how many out there in the world, millions? THis thread could take a while. Narrowing down to one wire at a time would help. Make it one that not too many people have and the topic might actually reach some conclusion in our lifetimes.

Carry on. I’ll be on some other thread that might actually add some value for someone’s hifi woes somewhere.

Given that, my advice to resolve the world’s wire direction dilemma that the world now faces in amazingly just a few words  (if one must)  is: ...drum roll... there are only two ways max to connect most wires (sometimes only 1). Try them both and see. Or buy one with directions that tell you if you want to be sure you got it right. Then start a thread about it and please be specific. Then perhaps we can get somewhere.

You are welcome...
This intellectual challenge: how to improve audio, is not interesting at all if we use money...Anybody can buy a costly amplifier and plug it with the "illusion" sometimes of hi-fi....


I'll buy that but what does it have to do with wire direction?  Staying on topic IS a virtue in debate.
I dont have an opinion about direction but the problem is way more deep than the skeptic would want to admit....


How's that?
I pity the fool who actually reads this entire thread thinking they will learn the answer on wire directionality.

Kudos to maghister though for throwing the intellectual kitchen sink at the problem. At least there is some interesting topics there for inquiring minds interested in learning things even if they have nothing to do with establishing wire directions. Maghister you are a major step up from geoffkait when it comes to going on and on about nebulous products and solutions that only you can fully understand.   Plus I am pretty sure you have nothing to sell and profit on as a result.
It's going to take way more words that have been spewed in this thread to-date to solve this one folks.   Step it up!

Nobody seems to know for sure. It’s a rhetorical question obviously, but I can definitely see people rolling their eyes if that will do.

Controlled tests are fine but there is nothing still that says cable y will behave the same as cable X you just tested. Even if its the same maker and model. The devil is always in the details and blanket statements are a slippery slope especially when big bucks are involved.

At least most low voltage wires can’t cause physical harm or injury on their own but that just means there are no legal bounds practically that a wiremaker and his claims can clearly cross and be held financially liable. IT’s just a hobby after all.
In science, you can have any theory you want. THen you collect data that you analyze statistically to determine if the data supports the theory or not. It either does or does not to various degrees. Nothing is ever "proven" 100% categorically.

So whenever you read that someone says X is true for reason Y and especially then they just talk a lot, take it with a grain of salt. It's merely an opinion at best and everybody has one.  Certainly resist the initial urge to open your wallet.

Or not. It’s a free country. One is free to believe whatever they choose and the gaslighters and con artists know that.
None of this arguing about science helps anyone in any practical way.   YEs its all gaslighting....and even that is done very poorly from even just a mere logic perspective.

I think someone needs to go out and write more papers and get it all reviewed and accepted by an authoritative body on the subject.  Not that even that will help the poor shlubs here who just want their hifis to sound good.   

If someone wants to nod their head and finds it enlightening somehow in some way, well good for them.    Count me among the unenlightened.  This place has become a garbage dump for people who can't find an audience elsewhere for their  brilliance.  Too bad!
M Yup. Have at it! I am fine with that. Aren’t you glad?

BTW I never attacked the OP personally, just what he/she wrote. Would reach the same conclusion if Mother Teresa actually wrote it. Whereas that makes me a bad person in your eye. Which is fine. It is what it is.
The ops word salad argument is a straw man. Plus the article referenced as described has nothing to do with wire direction. Just a setup to suggest that anything is possible.


A total waste of time. I’m sorry I even read it and bothered to post. That’s all. 
That’s good.  Then forget about me and just move on then please instead of telling me how uninformed I am.
No but I am sure people will continue to tell us what we should be  hearing. So much for trust your ears. Who came up with that ridiculous concept anyhow?
And try to study what is recommended before spitting something...


Not that this justified an answer but I’ve been studying these things for years. So I suspect my opinion is at least as educated as yours.
I said it was useless or worse which is my opinion. Sorry if it bothers you. Never mentioned bull-sh-t but hey if the shoe fits. 90% of it anyway.
What are you talking about?   I said its my OPINION.   IS your's opinion or fact?
I understand it perfectly.   I said it.  Maybe its you who needs to work on it? Or just accept an opinion that differs from yours.
Calling out a bunch of gaslighting when observed is a very positive thing IMHO. It’s the gaslighting that is negative.
I’m deciding for me M not others obviously and merely stating my opinion like everyone else including you. If it bothers you, I can’t help that.
My only thought for this topic is so what?

If someone sold you directional wire, especially expensive directional wire and forgot to tell you which way is the right way, I’d find another more competent vendor. Or maybe it just really does not matter? There is always something else one can find to obsess over.  Or if playing with wires is simply what floats ones boat, more power to you.
I am keeping tabs on threads these days....this one goes under "totally useless". That’s being kind. Gaslighting people is even worse than useless.
