Sansui | Japan

Sansui Electric Co., Ltd.  is a Japanese manufacturer of audio and video equipment. Founded in Tokyo in 1947, Sansui initially manufactured transformers, but by the 1960s 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.

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. Unfortunately the SQ system developed by Columbia/CBS was the most popular so called 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/Quadradisc by Japanese JVC and American RCA. Most big record companies used either SQ or CD-4, but Decca used the Sansui QS system.

During the late 1970s the iconic matte-black-faced AU-series amplifiers were released. 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. The separate pre-amp/power-amp CA-F1/BA-F1 topped the model range along with the AU-X1 integrated amplifier.

In the UK around 1982, the Sansui AU-D101 amplifier and its more powerful sibling the AU-D33, were highly acclaimed by audiophilesand were so well matchedto 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 2nd order harmonic distortion.
