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

Mr. geoffkait

Nothing can be explained by directionality. It is one of the worst inventions of the cable industry ever. An absolute bull----.

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. In such a case, the most difficult would be for the power grid that distributes a tremendous amount of power. If that would not be symmetrical, the difference would cost a lot and be a problem to deliver. Look at the power grid: millions of miles of wires, no one complains of directionality. No other but audio cable makers ever bothered with that. Those audio cable makers and sales rep. do, just because they charge money (a lot!) for no particular reason, but a lie.

The way to explain why a Hi-end called (by you) cable, that costs US $10,000 sound inferior to a US $ 100.- DIY cable is the cable’s resistance ratio between the amp’s DF and the cable’s resistance. When this is calculated per system, the results are in the impression sharing’s of members of this site who tried it. They say the truth. They show gratitude. They are honest and put away a US $ 10,000.- cable away, back to the box over a US $100.- DIY they just compared too.

Your say, is the proof of the cables industry attitude to the clients: spitting in their face.

>>>>>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.
