power cord directionality


IF power cords do indeed have preferred directionality, and one is inadvertently flipped for a few hours, does it "harm"it?

Sorry, I thought the topic on this thread was related to "power cords"

not to be confused with "signal"

In a perfect world you should never hear power or its side effects.

You want the signal to be clean.

One can’t help wondering how does vibration affect the power cord? Assuming it does, obviously. Or, if you have an argument that vibration doesn’t affect the signal be my guest. Share, share!
Shirley you jest, mc. It’s the same for any cable or fuse or any wire. External vibration distorts the signal. Just like shaking a magnet 🧲 distorts the magnetic field lines. That’s why it’s always best to damp the wall outlet and suspend the power cord.

I was kind of hoping you could tell me. Just a gut feeling? Oh, well, that’s the way it goes sometimes. 🙄 By the way Poynting angles are not (rpt not) incompatible with the idea of vibration distorting the signal in cables and wires. Besides, if the signal didn’t travel in the conductor it would matter what metal or purity was employed for the conductor.

If solid core wire is directional who figures out which way it goes when wiring a house?

I never said directionality and vibration are related. They aren’t.
All right.
Somebody clear this up for me- very specifically, what the heck kind of cord are we talking about here??!
The OP was referring to an umbilical cord... NOT the type that connects a placenta. (for those easily confused)
....and fabricator of cable clarified how it was just labeled backwards.....as it has Neutrik terminations, testing would reveal, due to the grounding at the power supply end, if it was backwards......thanks to all for some helpful, some not-so-helpful, but always OPINIONATED,  answers.....I must admit I have learned some things on this site, both about equipment AND about personalities....
Now I wonder why was it even bothered to be  labeled since it only connects one way..... (?)
So let me understand. are you saying vibration can have a negative effect  on how electrons flow? If you shake/vibrate any wire enough, it is possible to change the position of an electron?

In my opinion vibration can have an adverse effect on a connection point of a wire.

example: if you have a low quality outlet the physical connection between the plug and outlet may not solid enough and you may have arcing. Also the more valuable precious metals used in the plating (gold/silver) may offer higher conductivity.

Audiogon's self-proclaimed reigning theoretical physicist, explains how vibration affects the signal:

jea48 wonders, How, exactly, does that work?

Then his specialty, the word salad:

Captain Irrelevant strikes (out) again.

Take a wire, let's call it an interconnect. Put a reasonable load on it, say 2K ohms resistor on one end, similar to the output impedance of a tolerable source. Now plug that into a headphone amp. Hang that interconnect 6" in front of a woofer (to eliminate magnetic coupling). Turn that speaker as loud as you want and see if you hear anything coming out of the headphone amp (or record and listen later). If you can't induce a signal 6" in front of the woofer on a sensitive interconnect, what do you think the odds are that vibration has any impact on an AC supply wire or speaker wire?

Just make sure you connections are tight, as that would be by far the most likely thing to modulate with vibration .... if anything actually did.
"Frequency is measured in the unit hertz (Hz), referring to a number of cycles per second." (Wikipedia)

There was no differentiation between AC or ohms....just frequency.
DC is a constant flow of power, with no fluctuation....unless you vary it....in a frequency.

If your speaker cables, signal interconnects, or input/output cables betwixt your computer to your system were only DC 'power'....without modulation of some sort....(the DC acting as a 'carrier' for the 'signal', which gets 'interpreted' by circuitry)....the 'signal' being 'fluctuations', be it digital or analog....

Digital is still hz, khz, or mhz.....analog gets the same descriptions.....

One ought to be able to extrapolate that cables of any variety are ambisexual as to 'direction'.  The wires Have to be able to 'go both ways'.

The whole issue of 'cable direction' imho is a farce....and a cruel and  expensive one at that.  And shields carry no frequency....hopefully...

The claim that X manufacturer has a means of creating 'directional qualities' into wires without effecting the quality of the 'signal' or 'flow' of same is on the order of claiming one has received a directive from kenjit that will create Perfection in said wire quality.

What are y'all smoking?  Can I have some?


You have 'positive' lines and 'negative' lines....

Doesn't that infer a loop?
Its called a circuit. The lines are hot and neutral, not positive and negative. Directional qualities are inherent in the materials not created by manufacturers. And the signals speaker cables and interconnects carry is AC not DC. 

Oh and you will hear it if you try. Or if not then why would it matter that others do?
