Geoffkait: "The reason why AC cables AND fuses in AC circuits are directional is because we only hear the effects of the portion of the alternating current that is traveling TOWARD the component."
With all due respect, repeating this falsehood over and over does not make it more true. Every link in the chain of an audio system right down to the cabling involves circuits. As someone else tried to point out to you, your loudspeakers are transducers that rely on both sides of the circuit to, uh, transduce. This is why many of us have phase switching built into our preamps-so that we can correct out of phase recordings. Push-pull applies to more than just amplifiers. It is the underlying foundation of domestic electricity.
>>>>OK, push-pull, we’ll use your words. What does that mean? Push-Pull - that means you have two wires for each channel, a L channel and R channel. For each channel there is a RED and BLACK wire. When current is traveling down RED toward the speakers it’s traveling in the opposite direction on the Black and vice versa. Then the directions reverse, at a rate of 60 Hz, with the current now flowing on the RED wire AWAY from the speakers and TOWARD the speakers on BLACK. Now, it doesn’t take a rocket scientist which I happen to be to figure out that if the wires for RED and BLACK are directional then it’s best if they are oriented in the right direction, no? And if you reversed the cables you would hear a difference in sound. That’s why I say you can throw away the current traveling in the direction toward the wall because you can’t hear it. You only hear current traveling toward the speakers. Follow? And that’s why ever since what, 25 yrs go, cable manufacture who knew the score, Audioquest, Goertz, Anti Cables, whoever, marked their cables with directional ARROWS. It's the same reason fuses in AC circuits are directional and why power cords are directional.
