Features of This Unit

Analog circuitry

This unit's improved audio quality amplifier circuitry drives the 

outputs from the D/A converters.

Texas Instruments DAC chips

This unit features Texas Instruments PCM1795 DAC chips in 

independent left and right dual monaural configuration.

USB input 384 kHz/32-bit supported

The USB B type input terminal makes it possible to input USB 

digital audio signals from a PC or Mac, supporting a sampling 

frequency of up to 384 kHz and 32-bit quantization.

USB input supports DSD

DSD format data from a PC, Mac or the like can be played 

via the USB terminal at sampling frequencies of 2.8 MHz, 

5.6 MHz and 11.2 MHz.

Asynchronous communication supported

Very low jitter has been achieved using dedicated USB input 

ICs with asynchronous communication and PLL.

Digital input terminals

This unit is equipped with a coaxial input terminal and an opti-

cal input terminal. It is compatible with S/PDIF format signals 

between 44.1 kHz and 192 kHz.

Digital inputs (S/PDIF) with low jitter has been achieved 

using AK4118AEQ chips manufactured by Asahi Kasei 

Microdevices Corporation.

Digital audio signals from other audio devices are played back 

with significantly improved audio quality.

Aluminum construction

The base for the CD mechanism is made from 8 mm thick, 

solid machined aluminum. Chassis structure rigidity has been 

highly enhanced as well as the aluminum front panel.

MQA (Master Quality Authenticated)

MQA is an award-winning British technology that delivers the 

sound of the original master recording.

The master MQA file is fully authenticated and is small enough 

to stream or download.

Visit mqa.co.uk for more information.

This unit includes MQA technology, which enables you to play 

back MQA audio files and streams from all digital inputs, de-

livering the sound of the original master recording. D-03X is a 

CD player that can recognise an MQA-CD. The built-in MQA 

decoder will automatically restore the high-resolution signal 

heard in the studio and confirm it, using the authentication 

signature.

Low phase noise crystal oscillator

This unit uses an oscillator with low noise near the oscillating 

frequency.

This oscillator provides clocking with less jitter.

Last memory function

Built-in flash memory can memorize settings such as dimmer, 

digital input selection, etc.

Dimmer function

Display brightness can be adjusted with 4 brightness levels.

Digital output OFF

The digital audio output can be deactivated to improve the 

quality of the analog audio output.

Analog output terminals

18 mm gold plated RCA terminals support high-performance 

line cables with large plugs.
