An audiophile is a person enthusiastic about high-fidelity sound reproduction.
Audiophile values may be applied at all stages of music reproduction: the initial audio recording, the production process, and the playback, which is usually in a home setting.
A key goal of audiophiles is to capture the experience of a live musical performance in a room with good acoustics, and reproduce it at home. It is widely agreed that this is very difficult and that even the best-regarded recording and playback systems rarely, if ever, achieve it.
The term High-end audio refers to playback equipment used by audiophiles, which may be bought at specialist shops and websites. High-end components include turntables, digital-to-analog converters, equalization devices, preamplifiers and amplifiers (both solid-state and vacuum tube), horn and electrostatic speakers, power conditioners, subwoofers, headphones, and acoustic room treatment.
An audio system typically consists of one or more source components, one or more amplification components, and (for stereo) two or more loudspeakers.
Signal cables (analog audio, speaker, digital audio etc.) are used to link these components. There are also a variety of accessories, including equipment racks, power conditioners, devices to reduce or control vibration, record cleaners, anti-static devices, phonograph needle cleaners, reverberation reducing devices such as speaker pads and stands, sound absorbent foam, and soundproofing.
