SA-CD Transport Accuphase DP-900

Full Description

Overview

The SA-CD drive in the DP-900 was developed in-house by Accuphase to assure the best possible performance. Its ultra-massive design combines superior rigidity with outstanding accuracy. Compared to a CD drive, an SA-CD drive has a higher revolution rate, and pickup positioning accuracy as well as suppression of vibrations must be of a higher order, to allow full access to the enormous amount of information stored on the disc.  In the transport, a digital servo with a dedicated DSP assures accurate readout of the signal recorded on the SA-CD using the DSD (Direct Stream Digital) principle. This is sustained by a single-lens/twin laser diode pickup mounted to a high-speed access mechanism. The mechanism not only realizes optimal reproduction of SA-CDs, it also is capable of extracting a super-accurate signal from conventional CDs. The output for both SA-CD and CD is provided via the Accuphase exclusive high-performance digital interface HS-LINK (RJ-45 connector). The CD output is also available via a dedicated coaxial connector.
