High-end audio is a term used to describe a class of consumer home audio
Home audio
Home audio, essentially, refers to any audio electronics intended for home use, such as shelf stereos and surround sound receivers, which are becoming the most popular piece of home audio equipment...

 equipment marketed to audio enthusiasts on the basis of high price or quality, and esoteric or novel sound reproduction technologies. High-end audio can refer simply to the price, to the build quality of the components, or to the subjective or objective quality of sound reproduction. The high-end audio movement started in 1962 with the launch of J. Gordon Holt

Justin Gordon Holt was an audio engineer and the founder of Stereophile magazine, and is widely considered to be the founder of the high-end audio movement, which promoted the philosophy of judging sound quality by subjective tests, generally with "cost no object" sound components, including...

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

The total harmonic distortion, or THD, of a signal is a measurement of the harmonic distortion present and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency...

, but the type of this distortion (2nd harmonic) is not as disturbing as the higher order distortions produced by poorly designed transistor equipment.

Items often questioned are accessories such as cables 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.
