An individual who is very interested and enthusiastic about the sound quality of a stereo or home theater system. Quality audio components are designed to reproduce the audio without adding any distortion or coloration.

Quite often, audiophiles are as passionate about the equipment they use as the music they listen to. An entry-level, audiophile-class stereo system typically begins around $10,000 and includes a CD player, AM/FM tuner, preamplifier, amplifier and two speakers. The highest-quality equipment with the same number of components can cost up to $100,000 and more. Contrast with videophile. See Laser Turntable and home theater.

Home Theater Sound
Starting in the late 1980s, the sale of high-end audio equipment was given a boost by the home theater market. The more realistic the sound, the more realistic the video experience, especially for action movies. The audio equipment in many home theaters is often more expensive than the video.

Sound Is Not Easily Remembered
Humans cannot easily remember sound quality if any time has passed in between. The only way to test audio fidelity is to switch back and forth between two systems playing the same music. It is almost impossible to accurately compare the quality of two stereo systems by listening to one and going to a different store to hear another. It is a rare individual who has that auditory capability. In addition, what sounds good in the showroom may sound entirely different in the home.
