Accuphase DP-770

The high-rigidity, high-precision drive traverse mechanism equipped with an outer rotor brushless DC motor drive rotates discs smoothly and delivers accurate data reading, while the 8MDSD (DSD signal) / 8MDS++ (PCM signal) type D/A converter driving the ES9028 PRO (ESS Technologies) processor in 8 parallel channels converts the inputs into highly precise analog signals. The DP-770 also incorporates numerous noise suppression technologies like ANCC* to create an unparalleled musical experience.
