The D-10X marks the debut of the world’s finest D/A converter, the MUS-IC™ BD34301EKV from ROHM Semiconductor. Used in dual mono configuration, these converters combine top-flight specs with an impressive suite of silicon-level refinements.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.
Our years of ODNF amplifier development have resulted in ODNF-u – Only Distortion Negative Feedback (ultimate) – which debuts on the D-10X. This fully balanced configuration maximizes error detection accuracy, minimizing distortion. You’ll hear far greater expressive power with enhanced microdynamics across the audio spectrum, especially in the higher frequencies. The stage also achieves a natural and smooth waveform without the conventional output filters. The secret is the tailored, gradual 1st order filter × 3 band processing inside the circuitry. Superb circuitry deserves a strong chassis. To protect the analog signal from changes in ground impedance and magnetic fields, the D-10X incorporates a composite, loop-less chassis. Well shielded, the chassis is also effective at blocking digital noise.
To provide highly abundant, highly stable power, we increased the power transformer capacity by 27% compared to our previous flagship. We also provide independent regulators for each circuit along with formidable filter capacitors for the ultimate stability.
Dielectric effects, unwanted resistance and stray capacitance in printed circuit board patterns can all degrade the audio signal. LUXMAN suppresses these effects with generously thick 100 μm copper foil, gold-plated connections and peel coat removal of the solder mask. In addition, our gently curved wiring pattern delivers smooth signal flow.
No detail is too small for LUXMAN engineers to consider and refine. The RCA output jacks apply gold plating over an alloy that combines the conductivity of copper with the durability of brass. We use rugged Neutrik XLR terminals for the balanced outputs. In addition, density gradient cast iron insulator feet provide firm support, while diffusing shelf-borne resonance.
To complement advanced audio systems, we provide one coaxial and two optical inputs, plus a USB input that supports both DSD and PCM. In addition to isochronous transfer, the USB supports four modes of Bulk Pet® transfer that optimize the processor load between the source and the D-10X for improved transparency.
You select your listening position carefully. The 4X zoom function makes the fluorescent display easy to read from that seat. When playing MQA-CDs and files, a three-color indicator confirms decode status: Studio (blue), Authentic (green) and Renderer (magenta).
The supplied aluminum remote control has the same blasted white finish as the player's front panel. Without leaving the ideal listening position, you can use the numeric keypad, transport controls and display dimmer.
