It features two CXD2552Q-2 digital-to-analog converters (DACs) with 45-bit noise shaping and 8x oversampling, significantly reducing jitter and distortion.

It offers a frequency response of 2 Hz to 20 kHz, dynamic range over 100 dB, signal-to-noise ratio above 117 dB, channel separation exceeding 110 dB, and total harmonic distortion below 0.0017%. The unit has fixed and variable analog outputs, an optical digital output, and a headphone output with volume control. The chassis is constructed from individually screwed copper plates with optional wooden side panels, contributing to its robust build and reduced vibration. Additional features include programmable playback modes, shuffle, fade in/out, peak search, and a remote control (RM-D991). Dimensions are 470 x 125 x 375 mm, weighing approximately 12.8 kg.
