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.

The phonograph is a device invented in 1877 for the mechanical recording and reproduction of sound.

In its later forms it is also called a gramophone (as a trademark since 1887, as a generic name since c.

1900).

The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record".

To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound.

In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones.

In later electric phonographs (also known as record players (since 1940s) or, most recently, turntables), the motions of the stylus are converted into an analogous electrical signal by a transducer, then converted back into sound by a loudspeaker.

Headphones (or head-phones in the early days of telephony and radio) are a pair of small listening devices that are designed to be worn on or around the head over a user's ears.

They are electroacoustic transducers, which convert an electrical signal to a corresponding sound in the user's ear.

Headphones are designed to allow a single user to listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air, for anyone nearby to hear.

Headphones are also known as earspeakers, earphones or, colloquially, cans.

Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place.

The other type, known as earbuds or earphones consist of individual units that plug into the user's ear canal.

In the context of telecommunication, a headset is a combination of headphone and microphone.

Headphones connect to a signal source such as an audio amplifier, radio, CD player, portable media player, mobile phone, video game console, or electronic musical instrument, either directly using a cord, or using wireless technology such as bluetooth or FM radio.

The first headphones were developed in the late 1800s from telephone receivers for use by telephone operators, to keep their hands free.

Initially the audio quality was mediocre and a step forward was the invention of high fidelity headphones.

Super Audio CD (SACD) is a read-only optical disc for audio storage, introduced in 1999.

It was developed jointly by Sony and Philips Electronics, and intended to be the successor to their Compact Disc (CD) format.

While the SACD format can offer more channels (e.g. surround sound), and a longer playing time than CD, research published in 2007 found no significant difference in audio quality between SACD and standard CD at ordinary volume levels.

A preamplifier (preamp) is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise tolerant and strong enough for further processing.

Without this, the final signal would be noisy or distorted.

They are typically used to amplify signals from analog sensors.

Because of this, the preamplifier is often placed close to the sensor to reduce the effects of noise and interference.
