High-end audio is a class of consumer home audio equipment marketed on the basis of high price or quality, and esoteric or novel sound reproduction technologies. The term can refer simply to the price, to the build quality of the components, or to the subjective or objective quality of sound reproduction.
The distinction between the terms high-end and high-fidelity (hi-fi) is not well defined. According to one industry commentator, high-end could be defined as "gear below which’s price and performance one could not go without compromising the music and the sound".
High-end audio equipment can be extremely expensive. It is sometimes referred to as cost-no-object equipment. Audiophile equipment can run the gamut from budget to high-end in terms of price range.
The human sense of hearing is subjective and difficult to define because of the way that electrical signals from the ear are interpreted by the brain. Psychoacoustics is a division of acoustics that studies this field.
Measurements can be deceiving; high or low figures of certain technical characteristics do not necessarily offer a good representation of how the equipment sounds to each person. For example some valve (vacuum tube) amplifiers produce greater amounts of total harmonic distortion, but this type of distortion (2nd harmonic) is not as disturbing to the ear as the higher order distortions produced by poorly designed transistor equipment.
Items often questioned[by whom?] are accessories such as speaker wires utilizing exotic materials and construction geometries, cable stands for lifting them off the floor (as a way to control mechanically-induced vibrations), connectors, sprays and other tweaks.
