The true audiophile believes that only the best will do, and they will commit the dollars to obtain cables that are not only sturdier, but provide optimum performance of their audio system. You can spend hundreds of dollars for audio cables, audio interconnect and gold plated connectors, but to the audio elitist the price is worth it, not only for the sound quality, but also for bragging rights. Still to many of us, it is hard to justify the added expense for the improved sound quality.

The basic purpose of a cable is to transfer the signal from point A to point B unadulterated. At audio frequencies the goal is to minimize losses by controlling the amount of Resistance, Inductance and Capacitance. There are four basic kinds of cables that one can use which are analog audio cables, audio video cables, audio speaker cable and digital cables.

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.

Video Cables are possibly the most important as the signal that is passed through is at a very high frequency. As the frequency increases it becomes more critical to ensure adequate shielding, solid terminations and proper impedance that audio video cables provide. Therefore it is necessary for a video cable to be adequately shielded and maintain characteristic impedance.

Audio speaker cables are usually fairly thick, and have two conductors; they can be tipped with spade lugs, metal pins, banana plugs or just bare wire. One needs to ensure that there is the tightest connection of the cable to amp and loudspeaker to minimize contact resistance. One should always remember to keep the speaker cable runs as short as possible and not to loop excessive cables as this may slightly increase cable inductance.

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.

Depending on your choice of audio requirements for sound quality, there are a host of cables available in the market. Most general purpose users do not need to look at the brands and quality of cables and the cheapest ones that come packages with the equipment work fine. Choosier customers may have to spend several hundred dollars to satiate their high quality desires. The main objective of these specialized cables is to transmit audio signals from one point to another unchanged. This involves minimizing losses by controlling Resistance, Inductance and Capacities at audio frequencies. Various specialized audio cables include audio video cables, audio speaker cable, analog ones and digital cables.
