is a Japanese audio engineering company headquartered in Chiyoda, Tokyo, Japan.[1] 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.
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[2]), the technology was improved, and the 2SK77B transistor was released. As V-FET devices are no longer manufactured, Digital do MaiN builds them itself.[3] Original design and usage of the 2SK77B V-FET transistor give amplifiers characteristics similar to vacuum tube devices[4] 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%[5] and no loss of original harmonics.[6] Digital do MaiN also uses technologies and complementary products from its partners: MSB Technology's (USA) DACs,[7] Cabasse (France) loudspeakers, Denon (Japan) waveform reproduction technology.[8]
