Template:Nihongo is a Brand & former Japanese manufacturer of audio and video equipment. Headquartered in Tokyo, Japan, it was part of the BermudaTemplate:Clarify conglomerate (from 2011).<ref name=audiocircuit>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The company was founded in Tokyo 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."<ref name="tube-amps">tube-amps.net 2015-01-02, Sansui in Early Days, retrieved 2020-04-23.</ref>
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.<ref name="tube-amps"/> By the 1960s Sansui had developed a reputation for making seriousTemplate:Huh 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.<ref name=audiocircuit/> Since 1965 the matte-black-faced AU-series amplifiers were released.<ref>hifiengine.com 2020, Sansui AU-111, retrieved 2020-04-25.</ref><ref>audiocircuit.com, Sansui AU-111, retrieved 2020-04-25.</ref> In 1967 Sansui produced its first turntable.<ref name="hificlass-2009">HiFi Classics 2009, Sansui-Geschichte und Informationen (Archive, German), retrieved 2020-04-23.</ref>
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 Quadraphonic 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 was the most popular matrix system. But later QS decoders could also play SQ records. Some Sansui receivers could also play the most advanced four-channel system: CD-4 (or Quadradisc) by Japanese JVC and American RCA. Most big record companies used either SQ or CD-4, but Decca used the Sansui QS system. The 2-channel-range was extended by tape machines and cassette decks.<ref>hifiengine.com, reel tapes by Sansui 1970-1974, retrieved 2020-04-23.</ref> The company also produced the Sansui AU-11000 in the mid-70s .<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
In 1974 Kosaku Kikuchi resigned, and vice-president Kenzo Fujiwara became president.<ref>Billboard 1974-10-26, page 4; at Google Books, retrieved 2020-04-22.</ref>
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).<ref>audio-database.com, SANSUI BA-F1, retrieved 2020-04-23.</ref>
In the UK around 1982, the Sansui AU-D101 amplifier and its more powerful sibling the AU-D33,<ref>Bigger version AU-D55, https://audio-database.com/SANSUI/amp/au-d55f-e.html, retrieved 2020-04-22.</ref> were acclaimed by audiophiles<ref>German HiFi magazine Stereoplay 04/1982: "Spitzenklasse IV"; best integrated amplifiers these times were in this magazine "Spitzenklasse I" (German "Spitzenklasse" means top class.)</ref> and were so well matchedTemplate:Citation needed to a pair of KEF Coda III speakers that they could be bought as a set from some outlets.<ref name=audiocircuit/> These amplifiers used a complex feed-forward servo system which resulted in very low second order harmonic distortion. Despite this success, Sansui failed to follow up with further mass-market audiophile components.<ref name=audiocircuit/>
As the mid-1980s arrived, sales were lost to competitors (Sony, Pioneer, Matsushita's Technics).<ref name=audiocircuit/> Sansui began to lose visibility in the United States around 1988, and then focused on manufacturing high-end components in Japan. The company began to manufacture high-end television sets and other video equipment, but ceased exportation. In the late 1990s, the company's brand was used on video equipment manufactured by other companies. The current manufacturer of the rebranded sets is Orion Electric, based in Osaka and Fukui, Japan. Its U.S. subsidiary markets products under the Sansui brand, among others. Sansui is thus a mere umbrella brand at present.<ref name=audiocircuit/> 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.<ref>sansui.us 2006-01-24, International v.s. Japanese Domestic Market, retrieved 2020-04-22.</ref>
Sansui had developed the patented α(alpha)-x balanced circuit,<ref>The New York Times 1984-11-11, SOUND: Separate Amplifiers Justify High Expectations, retrieved 2020-04-18.</ref> 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.<ref>radiomuseum.org (with pictures; partly German) retrieved 2020-04-23.</ref>
Its latest amplifiers included the a-u alpha series like the 707´and 907 (1987)<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> au-x1111 (round about 1990)<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and others; b-2105 mos with a weight of Template:Cvt (1999)<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Sansui ended its Japanese production of high-end amplifiers some time between 2002 and 2005.Template:Citation needed In 2001 the headquarters in Shi-Yokohama was closed.<ref>sansui.us 2006-01-25, The Best of SANSUI, retrieved 2020-04-24.</ref>
