STAX
Stax was a Japanese company founded in 1938. In 1960, twenty-two years later, Stax released SR-1, their first electrostatic ear speaker. In 1993, the company was able to produce a variety of audio products such as ear speaker, CD player, tonearm, DAC, loudspeaker, and phono cartridge.
Two years later, it bankrupted but luckily revived the following year. In December 2011, Edifier, a Chinese loudspeaker manufacturer, announced its 100% equity acquisition in Stax.
