but i also notice that when i use my klotz cables.. pag natatapakan or medyo nahahampas sya sa kahit anong bagay.. nag kaka noise.. may static... pag sa nobelle hindi..
is it because of the plastic (coating or insulation ?)
Maybe this one will help to explain it; cables and interconnects (unbalanced/balanced type), are composed of the three main elements: the signal conductors, the DIELECTRIC, and the terminations. The conductors carry the audio signal; the dielectric is the INSULATING material between and around the conductors; and the terminations provide connections to audio equipments.Each of these elements- called cable geometry- can affects the cable sonic characteristics.
Conductors are usually made of copper or silver wire. Focusing on the dielectric (the material surrounding the conductors, and is what gives the cable some of their bulk) alone, it has a large effect on the cable's sound. Dielectric materials absorb energy, a phenomenon called dielectric absorption. A capacitor works in the same way; a dielectric material between two charged plates stores energy. But in a cable, dielectric absorption can degrade the signal. The energy absorbed is released back into the cable slighly delayed in time- an undesirable condition. Dielectric materials are chosen to minimize dielectric absorption. Less expensive cables and interconnects use plastic or PVC for the dielectric. Better cables use polyethylene; the best cable are made with polypropylene or even Teflon dielectric.
SKIN EFFECT, and interaction between strands, are the greatest sources of sonic degradation in cables. Skin effect, a condition where more high-frequency signal flows along the conductor's surface, less through the conductor's center. A problem with some cable design, is a tendency for a signal to JUMP from strand to strand if the cable is TWISTED, NATATAPAKAN or NAHAHAMPAS. One strand may be at the outside at a point in the cable, then be on the the inside farther down the cable. Because of skin effect, the signal tends to stay toward the outside of the conductor, causing it to traverse strands. Each strands interface acts like a small circuit, with capacitance and a diode effect (sorry, too technical here). Individual strands within a conductor bundle can also INTERACT MAGNETICALLY. Whenever, currents flows down a conductor, a magnetic field is set up around the conductor. If the current is an alternating-current audio signal, the magnetic field will fluctuate identically. This alternating magnetic field can induce a signal in adjacent conductors, and thus degrade the sound. Overall, quality design counts but beware; there's a lot of hype and just plain misinformation about cables. Manufacturers sometimes need to invent technical reasons for why their cables sound better than the competition's. In reality, cable design is largely a black art, with good designs emerging from trial and error (and careful listening).
