SANSUI CD - α 717 d CD-player with two third generation Mash. In order to convert digital signals read from CDs into analog signals more faithfully, we have adopted a unique D/A converter system that operates in complimentary service mode with two 3rd generation Mash installed. This system doubles the resolution of the PWM output as a 1-bit 8-DAC twin balance system. We have succeeded in improving the S / N ratio by eliminating in-phase noise and thoroughly improving the distortion in the high frequency range. In addition, the digital signal is instantly balanced into a 1-bit signal and the analog signal is directly output. This eliminates in principle the generation of 0 cross distortion and non-linear distortion that occur in multi-bit systems, and achieves excellent reproduction capability in minute level signals. The power supply uses a multi-power supply system with 15 independent power supplies to prevent degradation of sound quality due to interference between the microcomputer, DAC, drive system, display, analog system, etc. We have also newly developed an electrolytic capacitor using low-magnification aluminum foil and a high-capacity transformer to realize a power supply with superior linearity over a wide range. In addition, the CD - α 717 dr has a transformer that floats and controls the vibration. One transformer is placed in each of the digital and analog systems to completely separate them from each other, and an independent power supply is provided even to...
