Founded in Tokyo in 1947, Sansui initially manufactured electronic parts, 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 the UK around 1982, the Sansui AU-D101 amplifier and its more powerful sibling the AU-D33, were highly 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 2nd order harmonic distortion. Despite this success, Sansui completely failed to follow up with further mass market audiophile components.
As the mid 1980s arrived, sales were lost to competitors (Sony, Pioneer, Matsushita's Technics). 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. 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.

成立于1947年在东京，山水最初制造电子零件，而是由20世纪60年代制定了声誉，使严重的音频组件。他们是在国外市场出售，并通过了下一个十年。山水的放大器和调谐器，从1960年到1970年留在音频爱好者的需求。
在英国，大约1982年，山水1.00 - D101放大器和更强大的同胞，非盟D33 ，有很高的评价，并因此发烧友以及相匹配的一对经营者总协会尾三的发言者，他们可以买一套从一些发售。这些放大器采用了复杂的前馈伺服系统，导致非常低的二阶谐波失真。尽管这方面的成功，山水完全没有跟进进一步大众市场的音响组件。
正如20世纪80年代中期后，销售输给竞争对手（索尼，先锋，松下的技术） 。山水开始失去能见度在美国大约1988年，然后集中于制造业的高端部分在日本。该公司开始生产高端的电视机和其他视频设备，但停止出口。
后来，这个品牌被中国人收购，并正式成为HIFI 垃圾
