A hi-fi setup is a type of audio system that provides high-fidelity sound. It typically consists of two or more speakers, an amplifier, and a source such as a CD player, turntable, or streaming device. The term 'hi-fi' is short for 'high fidelity, ' which refers to the quality of sound produced by the system. The term 'STEREO' is derived from the Greek word for 'SOLID, ' and it refers to the two-channel sound produced by a hi-fi setup.
