High End Audio Cables Are Most Desired

Audio cables are the lifeline of any audio system.

Balanced audio circuits are very well being used in many professional audio equipments. Many professionals tend to prefer balanced and unbalanced connection, as balanced audio circuits benefit from a common phenomenon such as "common mode noise rejection,", in which noise  induced into balanced audio cables tend to be cancelled out as the desired signal runs in differential mode, while the noise arrives in common mode.

It should be kept in mind that device at one end supports either balanced or unbalanced connection, while the other device supports unbalanced (usually through "RCA" connectors) connection only. It is almost always better to hook your equipment up from balanced to unbalanced connection.
