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.
