LUXMAN D-03X

Ο διαχρονικός σχεδιασμός συναντά την τεχνολογία αιχμής. Το νέο D-03X της LUXMAN συνδυάζει την παραδοσιακή αναπαραγωγή CD RED BOOK με ένα προηγμένο κύκλωμα DAC υψηλής ανάλυσης που διαθέτει πλήρη αποκωδικοποίηση MQA.

Κρίσιμης σημασίας, το D-03X κληρονομεί τη φιλοσοφία και την εμπειρία των διαδοχικών ψηφιακών συσκευών αναπαραγωγής LUXMAN και παραμένει πιστό στις διαχρονικές αρχές σχεδιασμού της LUXMAN, όπως το στιβαρό πλαίσιο, το μεγάλο τροφοδοτικό και η σχολαστική επιλογή κυκλωμάτων. Το αποτέλεσμα: αναπαραγωγή αβίαστης μουσικότητας.

Highly advanced digital decoding

The D-03X can reveal new subtleties in even the most familiar music. MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The player includes MQA technology, which enables you to play back MQA-CDs as well as MQA audio files up to 24-bit transferred via USB, optical and coaxial inputs. The USB input also supports PCM data up to 384 kHz/32-bit and DSD data up to 11.2 MHz while the optical and coaxial inputs accept PCM signals up to 192 kHz/24-bit. In addition to conventional “isochronous” file transfers at fixed bitrates, the USB input supports four modes of Bulk Pet* high-resolution audio file transfer. Bulk Pet, optimizes data packaging and delivery to the DAC easing the processing load for both the host CPU and the device CPU enhancing playback stability and ultimately yielding improved sound quality. All signals benefit from a high-precision, low-jitter, low-phase-noise master clock, minimizing noise near the oscillation frequency and optimizing transmission accuracy.

Engineered in every aspect

At LUXMAN, we matched the meticulous disc transport and digital design of the D-03X with a thoroughly engineered chassis and analog output stage. The asymmetric mechanical layout places the CD drive at the left – ideal for signal flow, resonance control and weight balance. Our robust box chassis frame shields the CD transport and delicate circuitry from external vibrations and noise. For the all-important analog circuit, we feed the outputs of the dual monaural digital-to-analog converters to a current-to-voltage converter stage. The following stage low-pass filter amplifier benefits from low impedance. Fully balanced outputs featuring Neutrik XLR connectors complement conventional RCA output terminals. LUXMAN’s unwavering attention to detail contributes to ultimate listening enjoyment.

Rugged CD transport with steel top plate

The CD transport mechanism achieves uncommonly stable playback with a steel top plate, an 8mm thick solid aluminum base, a shielded box sub chassis and a loop-less structure. Undoubtedly expensive, these advances achieve uncommonly smooth, accurate and quiet disc read.

Dual Monaural D-to-A converters

LUXMAN engineers selected a pair of Texas Instruments 32-bit PCM1795 digital-to-analog converters to process digital signals with remarkable precision. Separating left and right channel conversion helps reveal the subtlest micro-dynamics.

Full complement of inputs and outputs

Full complement of inputs and outputs To support the widest range of associated equipment, the D-03X provides 18mm pitch gold-plated RCA outputs and high-end Neutrik balanaced XLR outputs. The USB input supports DSD and PCM signals, while the player offers coaxial and optical digital inputs and outputs.

Oversized power supply

For superbly stable voltage, the D-03X incorporates a massive power transformer, independent regulators for each circuit and large capacity filter capacitors. To minimize even subtle effects from magnetic fields, ground impedance and digital noise, the chassis is loop-less and shielded.

Display with zoom mode

LUXMAN’s zoom mode makes the fluorescent display easy to see from a distance. In addition, a multi-colored LED indicates MQA decode status (blue for Studio, green for Authentic, and purple/red for Renderer).

Aluminum remote control

The supplied aluminum remote control has the same blasted white finishes the front panel. You can use the numeric keypad, transport controls and display dimmer without moving from the ideal listening position.

LUXMAN’s original playback software

For playing back music from a personal computer, we recommend our LUXMAN Audio Player application. Available for Windows® and MacOS® systems, the software enables superlative USB output of FLAC, ALAC, WAV, AIFF, MP3 and DSF/DSDIFF files. (You can download the application from the official LUXMAN website.)
