DIGITAL PLAYERS
D-07X
Inheriting LUXMAN’s outstanding flagship pedigree A new class of digital media player

Many of the audio formats available today are undergoing a transformational period. By providing digital circuitry that supports advanced, high resolution file formats and the latest DAC environment, this model brings out unprecedented excitement from CDs and SACDs, which are still in an important position as audio media. The D-07X inherits the luxurious styling and oustanding performance our flagship model, the D-10X. This advanced digital media player delivers overwhelming performance. It truly conveys the ambience and feeling of recorded music over a wide range of media, delivering the finest listening experience.

Advanced DAC circuitry, reproducing digital media with excellent sound quality
Following standards set by our D-10X flagship model, high-end BD34301EKV DAC chips manufactured by Rohm Co., Ltd. in dual monaural configuration lie at the core of the digital circuitry that processes various digital media from discs, such as CDs and SACDs, to the latest high resolution audio files with exceptional quality. Over a USB input from a PC, Mac, NAS for audio, etc., the D-07X supports a wide range of format encoding up to PCM768kHz/32 bit and DSD22.4MHz. Bulk Pet transfer, which equalizes transmission load, can also be selected by using our dedicated driver software. Furthermore, for the popular high-quality format MQA (MQA-CD/MQA file), which expands the field of optical discs, streaming USB, COAX, and optical. The clocking system is designed to support accurate digital signal processing and is equipped with two high-precision, low-jitter, ultra-low phase noise modules that reduce noise near the oscillation frequency to a minimum. There is also a built-in, 2-mode analog FIR filter that allows you to select your preferred sound quality when playing SACD or DSD files.

HIghly robust LxDTM-i drive mechanism
The D-07X employs a left-side mechanical layout with an asymmetric configuration that realizes the shortest and ideal audio signal path and affords space for high quality analog circuitry. The disc drive section that supports CD and SACD playback is based on our original, highly robust LxDTM mechanism, which features a robust box structure that covers the entire mechanism with a side frame and top plate. Our LxDTM-i* system has evolved into an integrated structure that firmly blocks external vibration by being mounted directly onto the strong chassis side panel, achieving high precision and stable signal reading performance, comparable to our D-10X flagship model. The disc tray is made of die-cast aluminum, eliminating unnecessary vibration and resonance effects on the loader mechanism and enabling precise and smooth loading operation.

*LxDTM-i is an abbreviation for Luxman original Disc Transport Mechanism-improved, which realizes stable signal reading and mechanical integrity.

Newly developed discrete buffer circuitry
As a component that handles digital sources, high-precision signal reading by the drive mechanism and advanced digital signal processing are very important, but it goes without saying that the high performance analog output circuitry which determines the final audio quality is the most important factor in realizing that deep musical expression expected from high-end components designed by LUXMAN. The D-07X has a newly developed I/V conversion system that receives the differential outputs of the paired BD34301EKV DAC chips, operating in monaural mode, and feeds four discrete, perfectly matched amplifier modules. High-quality buffer circuitry lowers the impedance of the output signal. The unit powerfully drives any integrated amplifier or control amplifier that would be the next stage component. Out-of-audible-range filtering, which is essential for digital players, is performed in the buffer stage instead of having an independent LPF stage, enabling the reproduction of natural and smooth analog waveforms, resulting in higher clarity and more immediate sound quality.
