Digital do MaiN (Japanese: デジタルドメイン株式会社 Dezitaru do MēiN Kabushiki Gaisha) is a Japanese audio engineering company headquartered in Chiyoda, Tokyo, Japan, which mission is design, development, manufacturing and sales of high-quality innovative audio equipment for individual users and small groups.[1] Company's management and R&D employees are concerned about development of new technologies to improve quality of sound and music listeners' satisfaction.[2] Company name emphasises symbiosis of analog and digital technologies (implemented, for example, in volume control subsystem); picture on its logo symbolizes input pin jack (left square), output pin jack (right square) and 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[3]), technology was improved, and 2SK77B transistor had been released. As V-FET devices are no longer manufactured, Digital do MaiN builds them itself.[4] Original design and usage of 2SK77B V-FET transistor give amplifiers characteristics similar to vacuum tube devices[5] 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%[6] and no loss of original harmonics.[7] Digital do MaiN also uses technologies and complementary products from its partners: MSB Technology's (USA) DACs,[8] Cabasse (France) loudspeakers, Denon (Japan) waveform reproduction technology.[9]
