Accuphase DP-770 SACD / CD Player

The Accuphase DP-770 is a SA-CD/CD player that is considered to be one of the best in the world. Extremely well-built with a solid, heavy chassis that helps to isolate it from vibration. The DP-770 uses a high-precision disc drive mechanism that is designed to read discs with accuracy and minimise jitter.

Advanced technology for accurate information retrieval

The newly developed SA-CD/CD drive with a total weight of 10.5 kg is mounted on a massive 8-mm thick bottom plate, resulting in highly efficient attenuation of external vibrations. Intensive research into materials and structural design is reflected in the traverse mechanism supported by four viscous dampers. This protects the pickup from resonances and enables it to perform its crucial task, ensuring highly precise data readout at all times. Near silent operation

Even very slight eccentricities or warping of media discs often can lead to various types of vibrations and wind noise when spinning at high speed. The viscous dampers of the DP-770 prevent the propagation of such vibrations, and the large bridge covering the disc cuts down on wind noise. As a result, operation noise is reduced to about one half as compared to earlier designs, making listeners forget that there is a rotating mechanism at all.

Silky smooth loading

The disc loading mechanism features a dual stay construction with steel bearings for the shafts. This ensures that the aluminum disc tray opens and closes with a super-quiet and smooth motion
