A term arising from the 1950s denoting a high fidelity audio system. The term fell out of use after the advent of stereo, but is used today to denote a class of audio equipment above the mass market which reproduces audio faithful to the recording. The term is best used to differentiate real audiophile audio equipment from the myriad of clock radios, cheap home theater in boxes, and offcourse systems designed for listening to music of the urban persuasion.
