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

Mr. kosst_amojan

Really?

All have no idea what a good sound is, but you? (or dealers, industry guys ect'.)

Let's let each one to define for himself what is the sound they like. Also, what is the sound they prefer. Not only you in favor of charging an arm and a leg for a mediocre or bad cable, but you also wish to tell that poor guy (that you just robbed US $10,000.- from) that this cable sound is the best for him?

I never said what is a better sound. I left that to the guys who did the DIY cable to say. It is their saying, their testimony, their impression, their decision. We live at times no one shall tell us good from wrong sound. Especially, when we pay for that or put the time to build it (DIY).

Changes in sound between two cables, no matter how expensive or how cheap, can be explained solely by directionality. Mystery solved! 

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.
