Accuphase DP-770 Precision SACD Player

Description 

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.

Accuphase DP-770 – Reference Single-Element SACD

Five years after the launch of their flagship integrated SACD player, the DP-750, the Japanese company proudly presents its successor, the DP-770. It utilizes many of the solutions from the reference DP-1000 drive and DC-1000 processor, reduced to a single unit. The DP-770 utilizes the latest version of the drive, with improved vibration damping from disc rotation, resulting in more accurate data reading. This allows the DAC to receive data virtually without distortion, performing better, generating less distortion, and producing lower noise. This is achieved at the level of the mechanical components, resulting in the latest model weighing 0.3 kg more than its predecessor, while maintaining nearly identical dimensions. The disc spins in a reinforced, flat chassis with the system's center of gravity located at the lowest possible position, and harmful air turbulence is reduced by the shape of the cover. The remaining micro-vibrations are eliminated by four high-viscosity, elastic pads with improved damping characteristics. Electrically, it is equipped with a brushless DC motor, ensuring an ultra-stable rotational axis. As a result, the noise floor is reduced by 12% compared to the DP-750, and harmonic distortion characteristics significantly decrease above 2 kHz, maintaining a negligible average level of 0.0001%. The converter section employs a proprietary MDSD/MDS++ circuit for DSD/PCM signals with a 32-bit Hyperstream ES9028 PRO processor from ESS Technologies, consisting of eight parallel channels using the ANCC noise reduction system. The latest generation of this configuration guarantees a 2.8-fold improvement in technical parameters. The latest integrated SACD player, of course, supports Accuphase acoustic equalizers, and its balanced output is equipped with a signal phase switch.
