Fejhallgato erositok topikban feltett kerdesre itt valaszolo, mert nem oda valo tema:

Szerintem két fundamentális probléma biztosan van a sodrott vezetékkel:
1. Az első probléma, hogy nem egyformán helyezkednek el az vezetékek:
A stranded conductor is made up of hundreds of strands (sometimes not much bigger than the thickness
of a human hair) bundled together to create a conductor. The strands on the outside present an ideal electrical pathway, but the ones on the inside have different electrical values. This causes the same
information to be distorted differently in different parts of the cable. The bigger the bundle of strands, the bigger the problem. The fundamental problem is that the position of each strand in the conductor is not consistent. Individual strands weave from the outside of the bundle towards the center and back again in a
standard bunched-conductor multi-strand design. Because the signal wants to take the path of least resistance, it will travel closest to the surface of the conductor – in this case the strands on the outside of the bundle. When an ‘outside’ strand weaves towards the center of the bundle, the signal will ‘hop’ to a neighboring ‘outside’ strand in order to maintain the path of least resistance. Since the strands are constantly wandering, the signal is constantly ‘hopping’ from one strand to another, causing the most harmful kind of distortion found in a cable. In addition, the contact between these bunched strands is less than perfect. The point of contact between strands is actually a simple circuit that has capacitance, inductance, diode rectification ... a whole host of problems. This happens thousands of times in a cable, and causes most of the hashy and gritty sound in many audio cables. This distortion mechanism is dynamic, extremely complex, and because of oxidation, will become worse over time.
2. A második pedig a mágneses interakció:
Magnetic Interaction is the other primary problem in cable design, both with a stranded conductor, and between conductors. A strand carrying current is surrounded by a magnetic field. Electric potential
is transferred as current inside a metal conductor and as a magnetic field outside the conductor. One cannot exist without the other. The magnetic field outside a conductor diminishes at distances away from
the conductor. (Density is 100% only at the surface of the conductor.) In a bundle, each strand has its own magnetic field. These magnetic fields interact dynamically as the signal in the cable changes. On a
microscopic level, a stranded cable is actually physically modulated by the current going through the cable, particularly with high current applications such as speaker cable. The more powerful magnetic
fields associated with the bass notes cause the greatest magnetic interaction, which modulates the electrical characteristics of the cable, which in turn modulates the higher frequencies. Because
the music signal modulates the contact pressure between adjacent strands, it also modulates the distortion caused by current jumping between strands.
Ezek nem jelentkeznek a normál vezetékeknél, ezért kevesebb kárt csinálnak.
