in 1947 by Kosaku Kikuchi, who had worked for a radio parts distributor in Tokyo before and during World War II. Due to the poor quality of radio parts Kikuchi had to deal with, he decided to start his private radio part manufacturer facility in December 1944 in Yoyogi, Tokyo. He chose transformers as his initial product line. Kikuchi's thought was "Even with higher prices, let's make the higher quality of products."

In 1954 manufacturing pre-amp, main-amp kits, as well as finished amplifiers which used tubes, was started; in 1958 Sansui introduced the first stereo tube pre- and main amplifiers.
By the 1960s Sansui had developed a reputation for making serious audio components. They were sold in foreign markets through that and the next decade. Sansui's amplifiers and tuners from the 1960s and 1970s remain in demand by audio enthusiasts.

Since 1965 the matte-black-faced AU-series amplifiers were released. In 1967 Sansui produced its first turntable.]

In 1971, Sansui introduced the Quadphonic Synthesizer QS-1, which could make simulated four-channel stereo from two-channel sources. Sansui developed the QS Regular Matrix

system, which made it possible to transmit four-channel sound from a standard LP. The channel separation was only 3 dB, but because of the human way of hearing it sounded relatively good. In 1973, Sansui introduced the more advanced QS Vario Matrix decoder with 20 dB separation. The SQ system developed by Columbia/CBS

used the Sansui QS system. The 2-channel-range was extended by tape machines and cassette decks. The company also produced the Sansui AU-11000 in the mid-70s .
In 1974 Kosaku Kikuchi resigned, and vice-president Kenzo Fujiwara became president.
In the late 1970s, the first-generation '07' models included the dual-mono power supply AU-517 and AU-717, and the second generation featured the updated AU-719, 819, and 919 were released. The separate pre-amp/power-amp CA-F1/BA-F1 topped the model range along with the AU-X1 integrated amplifier (1979).
In the UK around 1982, the Sansui AU-D101 amplifier and its more powerful sibling the AU-D33, were acclaimed by audiophiles and were so well matched to a pair of KEF Coda III speakers that they could be bought as a set from some outlets.[ These amplifiers used a complex feed-forward servo system which resulted in very low second order ]harmonic

and Fukui, Japan. Its U.S. subsidiary markets products under the Sansui brand, among others. Sansui is thus a mere umbrella brand at present.[ This radical change in Sansui's corporate identity has resulted in a notable change in its product quality as consumers now tend to consider Sansui a mass-market brand rather than a maker of high-end electronics.
Sansui had developed the patented α(alpha)-x balanced circuit, that used in its high power amplifier along with the so-called double diamond differential, another patent for balanced driver stage. Lately Sansui had developed a turntable, P-L95R, with a handling similar to CD-players; it allowed to play both sides of the record without turning it.
Its latest amplifiers included the a-u alpha series like the 707´and 907 (1987) au-x1111 (round about 1990) and others; b-2105 mos with a weight of (1999)
