產品特點:
全球率先使用日本ROHM Semiconductor Co. Ltd最新又最強，更被譽為世界上最好的D/A轉換晶片MUS-IC™BD34301EKV（雙單聲道架構下的D-10X，每聲道動用一枚），亦即MUS-IC™BD34301EKV也是藉D-10X首度亮相。一款頂級規格的32位Delta-Sigma晶片、訊噪比強達-130 dB的轉換器。於研發上，單係針對音質進行的優化，多達28項，更深入到矽層面，包括電路設計及佈局、Photomask光掩模、晶圓生產及封裝等方面。例如由芯片到引線框架的連結線，他們選擇了更有利音響質素的銅線而非大路的金線。
強化電源
為了提供充沛又穩定的電源，強化供電勢在必行，跟上一任旗艦相比，D-10X除電源變壓器容量增加了27％外，還為每個電路提供獨立穩壓及強大的濾波電容器陣，以實現最高的穩定性。
獨特的Luxman PCB佈局，印刷電路板銅跡的圖案，對於電介效應、不必的電阻及雜散電容現象有著顯著影響，規劃不當必降低音頻訊號的質素。Luxman慷慨地以厚達100μm銅箔及鍍金連接，並去除阻焊塗層之同時，再以看上去彎彎曲曲、實則係柔和地彎曲的銅跡圖案及佈局，以促進訊號平順流動，從而抑制上述影響。
精選高級元件
對於Luxman工程師，任何可提升音質的細節，他們都會加以考慮，例如在非平衡輸出用RCA端子的選料上，就採用了將銅導電性與黃銅耐用性融合的合金再加以鍍金，而平衡輸出用XLR端子則是最值得信賴的Neutrik製作。（順帶一提：如使用XLR端子接駁D-10X的話，得當心相位配對，Luxman之平衡傳輸為1 GROUND / 2 COLD（-） / 3 HOT（+）模式，如受訊一方剛好相反，屬GROUND / 2 HOT（+） / 3 COLD（-）的話，可簡單直接地按動D-10X的相位切換掣，以修正跟受訊一方之相位差。）
數碼輸入
D-10X除可直接播放傳統Red Book CD、SACD及MQA-CD外，亦可利用USB輸入接收高至24bit MQA音樂檔、高至32bit / 786kHz PCM訊號，又或高達1bit / 22.4 MHz DSD512訊號。其光纖及同軸輸入則可接受MQA及高至24bit / 192kHz PCM訊號。除以固定比特率進行的常規「同步」文件傳輸外，USB輸入還支援Bulk Pet高分辨率音頻檔案傳輸的四種模式，這些模式可優化數據打包及送抵DAC之傳遞工作，減輕主機CPU及設備CPU的處理負荷，從而增強播放穩定性，令聲音透明度得以提高。
另，要藉PC播放音樂檔，廠方建議使用Luxman原廠播放應用程式LUXMAN Audio Player。這軟件支援FLAC、ALAC、WAV、AIFF、MP3、DSF及DSDIFF檔案。LUXMAN Audio Player可從官方網站下載，適用於Windows或macOS。
Product Features:
Latest LxDTM-i transport
To minimize even the slightest distortions triggered by vibration and resonance, we upgraded the disc drive, creating the LxDTM-i – LUXMAN original Disc Transport Mechanism (improved). We enclose the drive in 8 mm thick aluminum sides that extend to the front and rear panels, plus a 5 mm thick steel top plate. For added protection, the physical mounting system forms an integrated structure that supports the side frame. Together with an improved disc reading mechanism, the result is playback of an altogether higher order.
Advanced digital processing
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.
ODNF-u balanced analog circuit
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.
Substantial power supplies
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.
Unique LUXMAN PCB layout
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.
Premium selected components
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.
Versatile digital inputs
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.
4X zoom display
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).
Ergonomic IR remote control
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.
LUXMAN’s original playback software
For playing back music from a PC, we recommend our LUXMAN Audio Player application. This software supports FLAC, ALAC, WAV, AIFF, MP3, DSF and DSDIFF files. You can download the software for Windows and macOS from the official LUXMAN website.
