Accuphase DP-430 CD Player / DAC (Opened box unit)
Dedicated CD player designed for the ultimate in sonic excellence — High-precision CD drive mechanism combined with high-performance processor section featuring support for 384 kHz/32-bit PCM and 11.2896 MHz/1-bit DSD.
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.
■ Power supply optimized for performance and sound quality The power transformer has separate windings for sup- plying the analog and digital sections. A strengthened reference power supply for the D/A converter ensures stability and minimizes noise. Both in terms of perfor- mance and sound quality, the results are outstanding.
■ Display can show sampling frequency and number of quantization bits
Besides showing track numbers and elapsed playing time, the display can also indicate the sampling frequen- cy and the number of quantization bits when using the external input and during CD playback.
■ Digital level control allows adjustment down to –60 dB The level control employs the digital principle for optimum accuracy and minimal degradation of sound quality. Integration of the level control function in the D/A converter prevents noise and provides a wide adjustment range down to –60 dB.
■Digital inputs and outputs for COAXIAL, OPTICAL, and USB (input only)
Harnessing the high performance of the built-in process- ing section, data from other digital equipment can be supplied to the DP-430 via the digital inputs and played back with high sound quality.
■High Carbon cast iron insulator feet with superior damping characteristics further enhance sound quality
■ Analog outputs provide a choice of line level and balanced types for shutting out external noise interference
■ Fully digital circuitry for mechanism control ■ Phase selector for balanced output
