Luxman D-03R CD Player/DAC

Description Features Specifications The D-03R is the successor to the D-03X, a digital media player released in 2020 that was well received for its ability to process high-resolution audio sources as well as CDs. For optimal playback of the CD format, which has been a staple of music media for over 40 years, the D-03R features LUXMAN’s traditional left-side mechanical layout, ensuring an ideal signal flow. A robust chassis structure minimizes vibrations, supporting accurate disc reading. At the core of its digital playback system, the D-03R is the first to adopt ROHM’s BD34352EKV DAC chips in a dual-mono configuration. This player also offers a wide range of digital inputs, allowing connections to a PC or network transport such as the NT-07. The DAC processors support data rates of up to 384kHz/32bit for PCM and 22.5MHz for DSD signals via the USB input, and up to 192kHz/24bit for PCM data via the COAX/OPT input, providing a powerful digital-to-analog conversion environment. Refined analog circuitry utilizes fully balanced I/V conversion to handle the differential outputs of the DAC chips. The unit also features a finely tuned output amplifier block, enhanced with LUXMAN’s custom components, delivering a powerful drive output to subsequent hi-fi components. This is evidenced in the excellent sound quality inherited from our higher-end D-10X and D-07X models. To ensure a stable voltage supply to each circuit element, the D-03R incorporates a highly stable power supply system with independent circuit power regulation and large-value filter capacitors dedicated to each of the mechanical, digital, and analog systems. The exterior design combines intuitive controls with a newly adopted, large OLED display for excellent visibility. The front panel features a sleek, square-edged front panel in an elegant Blasted White finish, creating a simple yet elegant aesthetic that enhances any listening space. The D-03R is a state-of-the-art digital media player that has been designed to preserve the value of our listeners' CD collections with supreme sound quality, while also supporting high-resolution audio source inputs, including the latest streaming services. Digital Circuit Utilizes ROHM BD34352EKV DAC chips in a dual-mono configuration for high-quality digital-to-analog conversion. Supports PCM 384kHz/32bit and DSD 22.5MHz via USB input, and PCM 192kHz/24bit, DoP (DSD) 2.8MHz via COAX/OPT input. Includes a full MQA decoder, supporting MQA format playback across all inputs (MQA-CD, USB, COAX, OPT) with a bypass function. Features a high-precision, ultra-low phase noise clock module, reducing noise around oscillation frequencies for improved sound quality. Offers a selectable filter function, allowing users to customize the sound (PCM: two digital filter modes when MQA bypass is active, DSD: two analog FIR filter modes). Implements various jitter reduction features optimized per input (USB: asynchronous transmission via dedicated DSP, COAX/OPT: high-precision clock via built-in DAIR). Analog Circuit Features fully balanced buffer circuitry (four identical amplifier units) that cleanly drives the differential outputs from the dual mono-mode DACs. Adopts a highly stable power supply, incorporating a large power transformer, independent regulators for each circuit and large value filter capacitors (DAC circuit capacitor capacity doubled from 3,300μF to 6,600μF) for stable, high-quality power delivery. Uses smoothly rounded-pattern PCB traces to ensure smooth current transmission while preserving the integrity of delicate audio signals. Employs OFC (Oxygen-Free Copper) non plated internal wiring to enhance natural signal transmission. Design & Construction Features a sleek, square-edged front panel in an elegant Blasted White finish, designed to complement any listening room. Equipped with a high-definition OLED display with four brightness levels, zoom display, and auto-dimming functionality. Built with a loopless chassis that isolates grounding impedance and magnetic field effects, combined with a shielded chassis to block digital noise. Offers comprehensive digital I/O connectivity, including USB, COAX, and OPT inputs, as well as COAX and OPT outputs, ensuring compatibility with various audio components such as the NT-07 network transport. Features high-quality, gold plated, 18mm pitch RCA terminals, accommodating large, high-performance cable plugs, alongside premium Neutrik XLR connectors. Equipped with a highly rigid AC inlet, allowing for flexible cable orientation, while supporting cable weight across the entire terminal. Features: Includes a newly added control input/output terminal, enabling remote operation via compatible devices and future expansion for wireless control. Comes with a luxurious aluminum remote control (RD-28) featuring a numeric keypad for enhanced usability. Offers LUXMAN Audio Player software, supporting multiple audio formats with high-quality playback (available for Windows and Mac, free for download online). Provides a dedicated driver for BulkPet transmission, optimizing USB audio transfer for high-fidelity sound quality (available for Windows and Mac, free for download online).
