 in 1970s (US Patent 4,216,038), technology was improved, and 2SK77B transistor had been released. As V-FET devices are no longer manufactured, Digital do MaiN builds them itself. Original design and usage of 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
