There are several types and dozens of brands of audio cables. The choice depends on what one wants to hook up and how concerned is about sound quality. Generally speaking, 5-7percent of the total system cost is considered adequate to be invested in cables. If one’s just listening to background music, news shows, etc., or if sound quality isn’t all that important, one can use practically any cable - even the cheap ones that come packaged with many audio components.

People who want improved sound quality for listening can find something in their price range from cable specialists. Specialized cables provide optimum sound quality and are very sturdy. These are a better alternative to generic speaker cables which offer lower sound quality and aren’t as sturdy. Although the specialized cables may be affordable, the cost still could be several hundred dollars for the speaker cables or analog audio interconnects. Some people may find that the extra money spent is well worth the benefits of better sound and pride in owning the very best in audio equipment.

Analog 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 connections are utilized for passing analog line-level audio signals that go between components. RCA audio cables come grouped in stereo pairs, one connection is for the right channel and one for the left audio channel. A good idea for line level analog interconnects is the use of a cable with the following qualities: well shielded to eliminate interference and external noise sources, and low in capacitance.

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.

Audio cables come in two different types and are usually a single cable. The first type is an optical cable; it transmits digital audio signals as pulses of light. The second form is coaxial cables look like standard analog cables, but what they do is transfer digital audio signals.

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.
