Home audio is usually divided into pure audio and home theater audio. Pure audio is also called HI-FI audio, which is composed of pure power amplifier (only two channel output), speakers and disc player, and is generally used to listen to music and songs. Home theater audio is also called AV combination audio, which can play music and songs in two channels, as well as multi-channel discs. "Audiophiles" generally play pure audio, and mainly listen to Western classical music.
