Accuphase MDS Compact Disc Player DP-430

Full Description

Overview
The Accuphase-developed high-rigidity, high-precision drive optimized for CD reproduction, along with a super-quiet and smooth disc loading mechanism ensure pure signal readout of the highest order. In the processor section, the MDS type D/A converter utilizes four DAC chips driven in parallel, and the filter amplifier features the newly developed ANCC (Accuphase Noise and Distortion Cancelling Circuit). CD transport section and digital processor are kept completely separate. In addition to a USB input, coaxial and optical connectors are provided for digital input and transport output. Quality construction and highly advanced digital technology fully reveal the potential of the CD medium and provide a listening experience that opens up new emotional depths even with familiar music sources.
