Zhongsan ShengYa Technological Co. Ltd maintains a modern twenty thousand square meter factory in Zhongshan, Guangdong and has been in operation since 1991. In 1995 the company broke into the European market with the establishment of Vincent Audio (Germany) with products under this brand subsequently gaining credibility through endorsement of HiFi magazines, most notably Stereophile who recently issued a B rating for the Vincent Tubeline SV-236MK integrated a very close derivative of the Sheng Ya A10 CS amplifier. While assembled in the same factory, Vincent models sell for prices around four times higher than Sheng Ya. The Sheng Ya amplifier is advertised by Cattylink as being a Vincent SV-236MK though this is not strictly correct.
