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.

Analog audio cables, like toslink audio cables, audio video cables, audio speaker cable and digital cables are the four basic types of cables that can be used to transfer sound. These cables transfer the audio signal from point A to point B unaltered. You control the amount of Resistance, Inductance, and Capacitance thereby minimizing losses at audio frequencies.

RCA audio cables have one connection for the left audio channel, and one connection for the right audio channel, as they are grouped in stereo pairs. The connections are used for passing analog line-level audio signals between components. You need to use low capacitance, well shielded cables for line level analog interconnects so that interference and outside noise do not drift into the signal.

Video Cables may be the most important cables as the signals that are passed through these cables are at a very high frequency. The higher the frequency, more critical it is to have proper impedance, adequate shielding and solid terminations which audio video cables provide. Thus, a video cable should be well shielded and should maintain the proper characteristic impedance.

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.

Although there are many types of audio cables, expensive ones are not necessary if listening to background music and radio broadcasts etc. The job of the cable is to pass the signal from source to output minimizing any interference. Paired RCA cables, preferably low in capacitance and resistance should be used for line level analog interconnects. audio video cables should have adequate shielding as a high frequency signal is used. audio speaker cable needs to be secured tightly to ensure low contact resistance. Special digital cables are available namely, coaxial and optical which transmit light pulses and digital signals respectively.
