Japanese audio engineering company
 is a Japanese audio engineering company headquartered in Chiyoda, Tokyo, Japan. The company name emphasises symbiosis of analog and digital technologies (implemented, for example, in a volume control subsystem); the logo symbolizes an input pin jack (left square), output pin jack (right square) and an innovative signal processing unit in between.
Technology.
Digital do MaiN's power amplifiers use V-FET technology transistors. Initially developed by Nippon Gakki Seizo K.K. in the 1970s (US Patent 4,216,038), the technology was improved, and the 2SK77B transistor was released. As V-FET devices are no longer manufactured, Digital do MaiN builds them itself. Original design and usage of the 2SK77B V-FET transistor give amplifiers characteristics similar to vacuum tube devices and Triode class A amplifiers which feature very high quality of output sound and cancellation of most of the even distortion harmonics, and allow noise distortion to be less than 0.005% and no loss of original harmonics. Digital do MaiN also uses technologies and complementary products from its partners: MSB Technology's (USA) DACs, Cabasse (France) loudspeakers, Denon (Japan) waveform reproduction technology.
