As simple a device as a fuse is: it still carries a sinusoidal signal/voltage, ALWAYS from source to load. NOT back and forth!
Also (as mentioned above): any fuse acts as an RLC circuit, the ’C’ of which will be determined by properties of its wave guide’s/conductor’s surroundings (ie: glass, air, bee’s wax, ceramic, end cap materials, etc).
Any commonly drawn wire will exhibit a chevron pattern in its crystal lattice, so: why not "directionality" and why Ohno Continuous Cast, single crystal wire sounds better, to so many?
Stated above are scientifically tested, measured and proven facts.
1) Your first statement above is completely incorrect. A fuse (to take your example) does not carry a voltage (whatever that means, since it is a meaningless statement in the first place). The idea of ’source’ and ’load’ are irrelevant in electrical theory; you can represent any part of a (linear-ized) circuit as a ’source’ with an ’impedance’ that is connected to the rest of the circuit ("load"). The fact that we as humans interested in hearing sound being reproduced interpret one component as a source and another as a load has nothing to do with the way in which electrical circuits behave.
2) All the parameters of an RLC representation of a real component will be influenced by the properties of the materials they are made and surrounded by. Not just capacitance.
3) The fact that a drawn wire will show a grain orientation does not imply your (or anybody else’s) opinion that there is any "directionality" or asymmetry in the way in which a non-DC waveform is transmitted through it.
4) Your "stated above" is not fact; it’s a mixture of poorly understood electrical theory/physics, and opinions. As is your idea that because materials with a high dielectric constant take longer to polarise therefore this justifies the phenomenon of burn-in.
5) Very little of what you have posted has anything to do with the topic of this thread, which is about the directionality of cables to audio signals.
Before continuing, kindly get a degree in electrical engineering (which I happen to have), rather than posting nonsense under the flag of "it’s new theory". No, it isn’t. The idea that electrical currents move as ping-pong balls in a tube is not based on "old theories"; it’s a (bad) analogy used today with high school students who start learning about electricity without having the mathematical background to understand different and more correct/complete representations. It’s neither more nor less than second grade students being told "you cannot do 2 minus 3" as they have not been introduced to negative numbers.
