Sansui AU-alpha777DG (1989)

 

Sansui was the first to adopt the MASH method (digital to analog conversion), which uses high-order oversampling and third-order noise shaping to instantly convert digital signals into highly accurate analog signals. To fully utilize the high accuracy of the MASH method, Sansui adopted a lithium tantalate element that has an accuracy close to that of a crystal oscillator and a wide lock range. This resulted in the establishment of a unique Linear & Direct D/A Conversion System (L.D.C.S.). The amplifier is also equipped with two dedicated transformers where the digital and analog sections are separated. This amplifier features 4 digital inputs and 8 analog inputs. To achieve both sound quality and convenience, a remote controller with a direct access rotary switch is used. The highly accurate 6-gang volume control allows you to turn the volume up and down and freely, switch between a total of 11 sources.
