No one actually knows how to lculate what speaker cable they need

Audio signal is an AC (Alternated Current). An audio signal as complex it may be can be simplified by a set of sine waves (of different frequency and amplitude). This is what the Nyquist sampling is about and all digital sound (CD, PCM and on) is based on.

A sine wave is a symmetrical wave (above and below the zero voltage line). So is the energy (Integral) of its positive and negative value (Sum equals to zero).

As so, every half wave, the current flow one way and the other half in the opposite way. If a cable would be directional or have a directional property, it would be a disaster to one half.

>>>>>Let’s not make this so difficult. The sound is worse when the current goes in one direction, but that direction is back toward the wall outlet.🔜 So it can be ignored. The ONLY DIRECTION that matters sonically is the direction toward the speakers. It’s not rocket science. 🚀 That’s why all wires in cables should be controlled for directionality, you know, if you’re at all concerned about the sound. When the cable is in the wrong direction it IS a relative disaster for the sound. Oh, it will work, but it just sounds worse. It’s an audiophile thing. It’s the reason fuses sound better in one direction vs the other, also why Audioquest controls directionality for all their high end cables AND power cords. 

Let's make it correct. About difficult or simple it is not for us to say. The basics of electricity are way different than what you suggest. Audio is AC and AC flow both directions, whatever we like it or not. The flow is symmetrical. In such case directional wire (do not exist! If you look for directional use a diode) would be good for 50% of the time and not good for the other 50%.

So Audioquest is whom you represent? Audioquest site and tutorial is mostly about ferry tails. If their explanations would be brought to an academic institute that deals with electricity and electronics, that would get a laugh and be disqualified in no time. So is your last post. Your say and Audioquest say, has nothing to do with reality. It is all about an excuse to justify a 10' long speaker cable to cost US $12,900.- The rest is not important, after the price is paid. Later on, a US $100.- DIY will prevail in sound quality and the US $12,900.-speaker cable will be retired.  

 

I already explained why wire is directional in both DC and AC circuits. Several times. You have twisted what I said to suit your own imagination. I do not (rpt not) represent Audioquest or any other cable company. I only represent myself. Why would anyone have to represent some company to resister a different opinion? Hel-loo! You act as though you never heard of fuse or cable directionality. Which is OK. But directionality of cables and fuses has been well established, documented and experienced by *many tens of thousands of customers* since Audioquest and other progressive cable companies first started controlling cables for directionality twenty-five years ago and since high end fuse companies first determined fuses are directional. More than 80,000 Aftermarket Fuses, most of which I dare say are for AC circuits, have been sold since they were first introduced fifteen years ago. Wake up and smell the coffee.

Finally, you are still mistaken about what I mean by directionality. I do not (rpt not) mean wire acts like a diode, not at all. What I mean by directionality is simply that wire, all wire SOUNDS BETTER in one direction than the other. You would be hard pressed to observe any other phenomenon by reversing cables or fuses other than a change in the sound. Follow?
