Before buying audio cables you should determine whether you think sound quality is important to you. There are so many different cables available; you want to be sure to get the most suitable one that meets your specific needs. A certain amount of money, usually between 5 and 7 percent of the overall cost for the sound system, should be spent on good quality cables. If sound quality is not your priority, you might want to stick with the cables that were included with your sound system.
People who are more keenly interested in higher sound quality have more options. Cable specialists have products designed for increased quality and durability. Some of these cables can cost as much as five hundred dollars or more. While many people have trouble telling the difference between sound coming through the most expensive cables and through ordinary cables, there is an elite that believes that no price is too high when it comes to owning the very best equipment for the ultimate audio experience.
A cable has one basic purpose: transference of signal from point A to point B without interference. For audio frequencies the goal is minimization of loss through the control of Resistance, Capacitance, and Inductance. The four basic types of cables that can be used for these purposes are analog audio cables, audio video cables, audio speaker cables, and digital cables.
For passing analog line-level audio signals between components, RCA connections are used. RCA audio cables are grouped in stereo pairs, with one connection for the left audio channel and one for the right. For line level analog interconnects it’s a good idea to use cables that are low in capacitance and are well shielded to eliminate interference and external noise sources from mitigating into the signal
The most important cables are video cables as very high frequency signals travel through them. Audio video cables provide proper impedance, adequate shielding and solid terminations found with high frequency, and the right type of cable can be critical. So the shielding and maintenance of the proper characteristic impedance need to be aspects of a video cable.
Audio Speaker cables can be ended with spade lugs, metal pins, banana plugs, or bare wire and are normally fairly thick with two conductors. To minimize contact resistance there needs to be the tightest connection of the cable to the loudspeaker and amplifier. Do not loop excessive cables and keep speaker cable runs as short as possible so that cable inductance is not increased.
Digital audio cables are a special group of their own. Of these there are two types: coaxial and optical. Coaxial digitals look just like standard analogs, but transfer digital audio rather than analog, while optical cables use light as a transmission method for audio signals. These types are also usually a single cable, where analog types are generally double plugs to stereo sound.
Investment on cables for audio equipment depends on one’s sound quality requirement, which depends on background music/news etc. For improved/better sound quality sturdy costlier specialized cables are to be bought. The four different cables available in the market are analog audio cables, audio video cables, audio speaker cable and digital cables. They move signals from point to point with minimum signal loss by controlling resistance/Inductance/capacitance. RCA connections used for analog audio signals use low capacitance cables eliminating interference/noise. Video Cables pass high frequency signals that require adequate shielding/solid terminations/proper impedance. Speaker cables are short/thick and require low inductance. Digital cables transmit digital audio signals.
