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

@geoffkait 

Regarding directionality, while I'm skeptical, I hope I've shown that I'm always willing to experiment and to find out for myself. If I've understood you correctly, all wire is directional and the difference between the "right" way and the "wrong" way (or maybe "most appropriate" and "least appropriate" ways) should be audible.

My questions to you are:
- do I need to get all cables the "right" way around to hear the benefit, so will it only work if I have the power cable, the interconnect, and the speaker cable all the "right" way around? Or will just the speaker cable be enough?
- would you expect a difference on only the positive leg of the speaker cable? Given that the negative leg is returning to the amplifier, this should be less audible, right? In the same way that the return path of an AC signal is heading back towards the amp and is therefore less audible/important.
- should the change be immediately obvious or do I need a burn in for the directional crystals to settle or something?

I'm asking as this is a very easy experiment for me to try. Given my new 0AWG cables I can flip the positive, negative, or both cables with reasonable ease. If I only need to get the positive "right" then I only have one cable to flip. If I have to get both "right" then one of the four combinations should sound better than the others. I guess one combination would sound worst (both "wrong"), two would sound similar (one "right" and one "wrong") and one should sound best (both "right").

Am I right there? If so, I'll try it when I get home and let you know. My guess is it should only take 10 minutes.

>>>>All cables, fuses in the system do not have to be in the correct direction to hear effects of one test but the more cables and fuses that are correct the easier it will be to hear the effect of reversing one cable or fuse. Some wire obviously cannot be reversed, e.g., transformer wire, capacitor, internal wiring of electronics or speaker. Not sure how you can have a power cord reversed since plugs prevent experimenting. Audioquest controls direction during manufacturer but I think they’re the only one.

- would you expect a difference on only the positive leg of the speaker cable? Given that the negative leg is returning to the amplifier, this should be less audible, right? In the same way that the return path of an AC signal is heading back towards the amp and is therefore less audible/important.

>>>>>I am pretty sure the plus and minus on each speaker operate push/pull AC, so both legs are directional. That’s why if you reverse the legs the speakers still play music but the music is in reverse Polarity.

- should the change be immediately obvious or do I need a burn in for the directional crystals to settle or something?

>>>>>The change should be immediate. If unsure if better or worse, repeat. The more cables and fuses that are correct the easier it will be to hear the next one you reverse, and so on.

>>>>>>If cables are brand new I’d give them a while to break in before making any judgements regarding direction. Or save them for last. The issue I foresee when you have two cables involved like ICs is one could be the opposite direction of the other, especially if you cut them yourself. The odds for any cable being “right” by accident is 50%. So, it makes it tricky to test, as you rightly assume. I have no idea if all conductor strands in your thick cable are in the same direction, they probably are - it would make things pretty impossible if they weren’t. If there is any writing on the thick cable jackets you can use that to keep the cables consistent since the jacket was most likely put on as the bare twisted wires came off the assembly line, but that’s a guess. You have to make some assumptions.

Am I right there? If so, I’ll try it when I get home and let you know. My guess is it should only take 10 minutes.

>>>>>I think that for interconnects or fuse it should take ten minutes. Speaker cables might be trickier.

Good stuff, thanks for the info. I'll do some tests.

b4icu,
I try to follow the steps given without success, I am using a iPhone. Thanks 

Mr. khiak,
Can't you get access to a PC?
