To overcome this challenge, they significantly upgraded the company''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s LxDTM disk drives. The new LxDTM-i is manufactured in Japan and the driver is packaged in an 8mm thick aluminum side that extends to the front and rear panels and a 5mm thick steel top plate. In order to increase production, the turntables are all made in Japan, and the physical installation system forms an integrated structure that supports the side frames. The improved disc reading mechanism helps to play music more clearly and achieve a higher level of playback.
Advanced digital processing:
Since D10X is the first product to use MUS-IC DAC decoding chip, the release of D10-X also marks the global debut of ROHM Semiconductor’s MUS-IC BD34301EKV digital-to-analog converter. Like Luxman, ROHM is a Japanese-based manufacturer with decades of audio expertise. Related information shows that this DAC converter has 28 independent parameters optimized for sound quality, including circuit design, layout, photomask, wafer production and packaging. For example, in order to optimize the sound quality, the chip is connected to the selected lead frame“Join”The wires are made of copper, while the others are made of gold. The converter uses 32-bitΔΣ(Delta-Sigma)By design, its noise-to-signal ratio can reach -130 dB. D-10X is equipped with a pair of MUS-IC BD34301EKV digital-to-analog converters in a dual mono mode, which can provide an unparalleled music experience.
In addition, D10X combines MQA files and MQA-CD“Master Quality Certification”Complete decoding, not only can play MQA records, but also can transmit up to 24-bit MQA-CD and MQA audio files via USB, optical and coaxial input.
SACD, CD and MQA playback and batch PET file transfer:
In addition to two-channel SACD and CD media, D-10X can also play multiple file formats via USB input and free LUXMAN Audio Player computer software. The software can be used for MacOS&174; and Windows&174C, can decode WAV, FLAC, MP3, DSF, DSDIFF, ALAC and AIFF files. The USB input accepts PCM signals up to 768 kHz sampling and up to 32-bit quantization and DSD signals up to 22.4 MHz/1-bit sampling. Coaxial and optical input can accommodate up to 192 kHz / 24 bit PCM digital audio.

The factory provides Luxman Audio Player application, which is convenient for users to connect D10X to play music from PC. The software supports FLAC, ALAC, WAV, AIFF, MP3, DSF and DSDIFF files. Users can download software for Windows and macOS from the LUXMAN official website.
In addition to the regular“Synchronize”In addition to file transfer, the USB input also supports Bulk Pure Enhanced Technology&174;(BulkPet&174;)Two modes of high-resolution audio file transfer. This can optimize data packaging and transmission to the converter, thereby reducing the processing burden of the host CPU and device CPU. This reduces the workload between reading and reproduction, enhances playback stability and improves sound quality.
ODNF-u balanced analog circuit:
Luxman developed the ODNF-u circuit based on the original analog ODNF amplification circuit and applied it to D-10X for the first time. This completely balanced configuration maximizes the accuracy of error detection and minimizes distortion. In the entire audio frequency spectrum, especially in the higher frequencies, through enhanced micro dynamics, the audio circuit has a greater expressive ability. The platform can also achieve natural and smooth waveforms without using traditional output filters. The secret lies in the customized progressive first-order filter inside the circuit.×3-band processing.
In order to protect the analog signal from changes in ground impedance and magnetic field, D-10X integrates a composite non-loop chassis frame. The chassis has good shielding properties and can effectively block digital noise.
Large capacity power supply:
In order to provide a highly abundant and highly stable power supply, Luxman has increased the capacity of the D10X power transformer by 27% compared with the previous flagship product. An independent voltage regulator and a powerful filter capacitor are also provided for each circuit to achieve the highest stability.
Unique Luxman PCB circuit layout:
The PCB circuit uses 100μm Copper foil, gold-plated connection and peeling coating to remove solder mask to suppress these effects. In addition, as much as possible to use softly curved wiring methods can provide a smooth signal flow.
Analog output:
The RCA output jack is gold-plated on an alloy that combines the conductivity of copper with the durability of brass. Neutrik balanced terminals can provide balanced XLR output, and the front panel“Phase reversal”Push the button to switch the polarity.
Multi-function digital input:
A coaxial cable and two optical inputs, and a USB input that supports both DSD and PCM. In addition to synchronous transmission, USB also supports BulkPet&174; Four modes of transmission, these modes can optimize the processor load between the source and the D-10X, thereby increasing transparency.
Display 4 times zoom:
The 4x zoom zoom function makes it easy to see the information on the fluorescent display from a long distance. When playing MQA-CD and audio files, the three-color indicator confirms the decoding status: Studio(blue), Authentic(green)And Renderer(Magenta).
Ergonomic infrared remote control:
The included RD-29 aluminum remote control has the same sandblasted white finish as the front panel of the player. Without leaving the ideal listening position, you can use the numeric keypad, transmission controls and display dimmers
