I have read it argued against by those who think they know Here is proof
Paul Speltz Founder of ANTICABLES
shares his thoughts about wire directionality. Dear Fellow Audiophiles,
As an electronic engineer, I struggled years ago with the idea of wire
being directional because it did not fit into any of the electrical
models I had learned. It simply did not make sense to me that an
alternating music signal should favor a direction in a conductor. One of
the great things about our audio hobby is that we are able to hear
things well before we can explain them; and just because we can’t
explain something, doesn't mean that it is not real.
I am intending to use about 33,000uF and up, depending on price and low frequency ripple current. Among the 105 degree caps, there are quite a few choices. What brand is usually the best ? Nichicon had a great reputation, is it still the same ?
@elliottbnewcombjr, what can I tell you? I get around. Stereophile forum RIP. 🙏
Round round get around, I get around, yeah (Get around round round I get around, ooh-ooh) I get around From town to town (get around round round I get around) I’m a real cool head (get around round round I get around) I’m makin’ real good bread (get around round round I get around)
I have forgotten the details of what I learned, but not that the knowledge exists, and where/how it is used, and many of the other things I learned and forgot the details on provided the framework for understanding other pieces of knowledge. When presented with a problem, I can draw on the tools I know exist, and brush up on fundamentals as needed.
It all comes down to the nature of you job, and people please don't take offence. In many trades, and many "professional" jobs, a large portion of the knowledge set is expected to be readily available, whether it is the mechanic at the dealership, your electrician, construction carpenter, your accountant, your dentist, your GP, a lot of civil engineering, they are almost always working from knowledge readily at hand. Contrast that to R&D engineers, medical researchers, many software developers, custom carpentry, etc. In one instance we expect an instant result. I bring my car in, you change the brakes. My tooth aches, you stop it. Do my taxes. Contrast that to where the outcome is less defined, and the path to get there is also less defined, not to mention the deliverable is not immediate.

learned after they get out.
a quickie 'wire directionality' search popped up a stereophile link with this from our own geoff kait
"Wire directionality, how bad is it?
People wonder all the time, is wire really directional and does it really affect the sound? Skeptics say no, wire is not directional, citing alternating current as the "proof" that wire can’t be directional since the current alternates 60 times per second back and forth along the cable so that the net loss of gain is zero. Unfortunately if wire directionality is REAL then audiophiles are in a lot bigger trouble than they probably realized. The reason they’re in deep kim chi is because if wire is directional that means that all internal wiring in components is directional, all speaker internal wiring, all crossover networks are directional, capacitors, inductors and resistors are all directional, not to mention all cabling, including stranded conductors, all speaker cables and digital cables. Oh, and fuses, of course, as well as transformers. Possibly power cords, too, and house wiring. Even stranded wire is directional since each strand is drawn through a die prior to being spooled up. It is that final die that determines the wire’s directionality. The crystal structure is deformed so that the surface and even below the surface the crystal structure favors one direction over the other. Like stroking a porcupines back it’s easier to do in the direction the quills are pointing than against that direction. Now hard would it be to keep track of all the wires as they come through the final die? Would it kill the manufacturers to ensure that all capacitors, wiring, inductors, transformers are installed in the proper direction?!

I agree, that’s a lot of trouble, IF you choose to believe it.
It is a pandemic mode so I am providing you with basic education on the Internet. You seem not to have grasped the idea of school yet. That is why I bring it down to your level.
"What do you think on the job training is all about?"
Applying fundamental knowledge one has learned at school to a particular situation at work. Any more sophisticated job would be hard to learn from scratch while working.
Most people forget rather quickly whatever they were taught in school, just my observation. l mean, come on, most people don’t even use what they learned after they get out. What do you think on the job training is all about? It’s convenient to define knowledge as whatever is left after you subtract out all that you’ve forgotten from school. Which for many doesn’t leave very much. I don’t count what you learn on TV. That’s the way the ball bounces.
Since we are talking engineering, my experience is, the ultimately better engineers, at least if you are trying to accomplish difficult work, are the ones whose marks were 80-90%, definitely not the ones near the bottom of the class. If they achieved high grades and had a social life, then they are usually the exceptional ones. There are some book smart ones, who are usually good at pure research, but not practical work, but there is a place for everyone.

cakyol This is a ludicrous concept. It has no effect on sound. Anyone who claims they can hear it is either very gullible to marketing or from another planet or on some psychedelic substance.
All the lonely newbies, where do they all come from? 👶 👶 👶
What value of capacitor and how are you using it? 10,000 hour, 105C capacitors are quite common up to a certain size and reasonably priced with lots of different vendors.
lets move to something that matters..... any engineers here to suggest which electrolytic capacitor is the longest lasting as long as being operated within its parameters ? I dont want to spend 200 bucks per one and have it blow up in 3 years ? Any practical experience ?

Well if nobody can answer the question I won’t worry much about it then. Probably not at all.
Unless there are arrows on the wires. Then I follow the directions provided.
I am disappointed though that @Geoffkait can’t answer the.....
last try...and lets call it a day and move on...to help other audio perfectionists..
so...audio cable have the same directionality as water copper pipes...I know...I had a pin hole leak in a line feeding basement washroom...had to cut out a substantial length and replace it with the new one....guess what?...I installed this new piece in a WRONG DIRECTION.....now, all bathrooms, kitchen, laundry etc etc upstairs, still have normal, wet water - and in my basement washroom I only get moist water :(
FACT from old teacher , a bad teacher can stop or hinder the average American student .
The worst teacher can NOT stop the 15% of American children who love to learn. American culture is the enemy of all American students from the worst ghetto to Harvard .
