Accuphase DP-770 SACD / CD Player



Highest performing combined SA-CD/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
