Bryston is a Canadian electronics manufacturer based in Ontario known for its high-end amplifiers, preamplifiers, and digital audio components. The company traces its roots to the 1960s as a maker of medical equipment under founder John Russell, and pivoted into hi-fi in the 1970s when his son Chris Russell began designing audio gear. Bryston released its first amplifier in 1973 and has since built a reputation on engineering-driven design, hand assembly, and an industry-leading 20-year warranty on its analog products.

While most often associated with the audiophile market, Bryston amplifiers have a long history in professional audio, appearing in recording studios, broadcast facilities, and large-format sound reinforcement. The catalog spans the Cubed Series power amplifiers (such as the 3B³, 4B³, 7B³, 14B³, and 21B³), the 9B SST multi-channel amplifier, the B135³ integrated amplifier, plus preamps, BDA-series DACs, BDP digital players, and a line of loudspeakers.

Bryston is now part of the same group as Axiom Audio, following Chris Russell's sale of the company to Axiom founder Ian Colquhoun. Manufacturing remains in Ontario, with the brand emphasizing locally sourced components, conservative power ratings, and long product lifecycles over frequent model turnover.

Bryston has 9 products cataloged on Equipboard, including Studio Monitor Amplifiers and Power Amplifiers. Their gear is featured by 1 artist, with the strongest followings in Electronic and Rock. Notable users include Nicolas Collins.
