The modern technology for audio cable is not significant progress for many years. Figure 8 speaker cable design, for example, there have been the earliest days of electronics. Today it is increasingly difficult for manufacturers to come with significant improvements in technology, and to draw on imagination and marketing-jargonised descriptions to gain attention.
Whether these new technologies actually work is another question but here is a briefOverview of the Top 5, and what they mean:
1) SCC OFC, UPOCC, SGC, SGSCC, etc.
This is one of the most popular and showcase current hype in the cable world. It has many names, but usually some abbreviation of a variation of single crystal copper. " The idea is that your standard copper cable containing many crystals per length of the wire. This is because all metals form crystals during the production, and if under less than ideal conditions, many crystals in the formBars. When drawn into a strand of wire, the crystals of different sections of the cable acting as a theoretically small resistors with different electrical properties. This then cloudy in the sound. SCC is a single crystal ingots of copper, which is produced under controlled conditions and thus is also created high-purity (6N or 7N).
2) Smooth surface copper
This works similarly to SCC, but by a different approach. A specialAnnealing is used to draw, for the copper gradually, to a smoother surface. Resistance of a cable is proportional to its cross-sectional area. So if the surface of a wire is not constant, the cable is theoretically made up of thousands of low resistance of variable quality. The smoother surface of the wire translates into a more pure conducting medium.
3) Teflon / cotton dielectric (insulation)
This is perhaps one of the less controversial technologieshow successful it lead in industrial applications. Electrical properties of conductive medium is scientifically proven, not only for the medium itself, but the dielectric of the medium, ie the insulation. The better the insulation, the electrical properties of the ideal. Teflon is one of the best practice materials known to man, for the purposes of isolation. Its dielectric strength is very high, but it is easy to handle and serves as a goodphysical barrier. Its use is only by air (without the possibility of using vacuum), which of course practical issues that separate where necessary, by two tightly twisted wires. to go a way around this is by using a layer of cotton. Cotton is very porous (it has many small strands that are separated by air). Again, this is a good way of insulating cable on a small scale, but it is not practical for the speakers or the high output signals.
4) SilverLadders
If one of the less controversial technologies Teflon is round, then silver one with considerable backing in the industry. Without experimental materials that are not practical to use as cabling, silver is the best conductor, we know. It is to be used to signal paths leads with minimal distortion in high-end laboratory equipment. It is used for medical applications, YV in research and prototypes of communications satellites. It has been armed with manyBrands say silver too hard. This argument has some foundation, as silver has an incredible power radio frequency (hence its use in demanding applications). But even this factor in the shortfall proves the quality of the connected devices. Silver is known to be very unforgiving to weaknesses in the other components that are used. Logic, therefore, tells us that it is not silver, hard, but it is rather the most honest.
5) treated cryogenicallyMaterials
When silver is the least controversial proposal, this may be the most idea out there, our 5 are listed first. Cryogenic treatment involves cooling a material to extreme temperatures (-180 ° C or -300 ° F), which was originally used to treat certain types of steel to improve its hardness and strength. In fact, the impact of calls on the internal structure of the steel production of finer grain. Ironically, this theory is in stark contrast to the single-crystal copper,which aims to reduce the number of grains. In addition, hardness increases at the expense of increased fragility, which will therefore increase the number of micro-cracks in the material. However, there are many companies out there that require the superior performance using this technology.
There is no doubt that many of these technologies are controversial. But what is never in doubt is our ability to judge for themselves. Use your ears and listenthemselves. This is the best advice anyone could give to the audio enthusiast.
