This Dac has an innovative MDS+ type D/A converter using four parallel DAC circuits ensures highly accurate D/A conversion of DSD and PCM signals. Separate configuration of transport and processor sections, each equipped with a set of HS-LINK, coaxial, optical, and USB (input only) connectors. USB connector provides support up to 384 kHz/32-bit and 11.2896 MHz/1-bit DSD. The SA-CD/CD drive employs a high-stiffness construction that not only minimizes vibrations from internal rotation but also absorbs any external vibrations, whether large or small.
Mechanical isolation between the traverse mechanism and the loading mechanism is provided by newly developed silicone type viscous dampers whose shape and material composition have been carefully optimized. Four of these are used to realize a floating design. The DP-570 features a strengthened rotation system and effective vibration frequency control, along with further improved vibration insulation. To combat wind noise, a larger bridge enabling air flow control is used, along with various other technology-based measures that result in a significant improvement in quietness. Disc rotation noise is reduced to about one third as compared to earlier designs.
The analog filter designed to remove so-called aliasing noise in the very high frequency range employs 5-pole Butterworth analog filters with extremely flat frequency response in the passband. In order to prevent unwanted interaction, completely separate low-pass filters are provided for the line and balanced signal paths.
