Befitting the company’s finest SACD/CD player, the Luxman D-10X is the world’s first home audio component with ROHM Semiconductor’s eagerly anticipated MUS-IC BD34301EKV digital-to-analog converter and also incorporates important new technologies in the disc transport and analog circuit.
Luxman engineers substantially upgraded the company’s LxDTM disc drive. Made in Japan, the new LxDTM-i encloses the drive in 8 mm thick aluminum sides that extend to the front and rear panels, plus a 5 mm thick steel top plate. The physical mounting system forms an integrated structure that supports the side frame. An improved disc reading mechanism contributes to music playback of exceptional clarity.
The D10-X marks the world premiere of the MUS-IC BD34301EKV digital-to-analog converter from ROHM Semiconductor. Like Luxman, ROHM is a Japan-based manufacturer with many decades of audio expertise. The converter reflects 28 separate parameters optimized for sound quality, including aspects of circuit design, layout, photomask, wafer production and packaging. A 32-bit ΔΣ (Delta-Sigma) design, the converter achieves a phenomenal noise signal-to-noise ratio: -130 dB. The D-10X features a pair of these converters in dual mono configuration.
In addition to two-channel SACD and CD media, the D-10X plays a robust selection of file formats via USB inputs and the free Luxman Audio Player computer software. Available for Mac OS and Windows PCs, the software decodes WAV, FLAC, MP3, DSF, DSDIFF, ALAC and AIFF files. The USB input accepts PCM signals at up to 32/768 plus DSD signals at up to 22.4 MHz. Coaxial and optical inputs accommodate PCM digital audio up to 192 kHz/24 bits. In addition to conventional, “isochronous” file transfers at fixed bitrates, the USB input supports two modes of Bulk Pure Enhanced Technology (Bulk Pet) high-resolution audio file transfer. This optimizes data packaging and delivery to the converter, easing the processing load for both the host CPU and the device CPU. This in turn reduces the workload between reading and reproduction, enhancing playback stability and improving sound quality, the company says.
Negative feedback is an extremely powerful tool in analog circuit design. But minuscule inaccuracies in the application of feedback can compromise the expressive power of music reproduction, Luxman says and for this reason the company has developed and refined the Only Distortion Negative Feedback (ODNF) circuit, culminating in ODNF-u, which debuts on the D-10X. This fully balanced configuration maximizes error detection accuracy, for greater musical expression across the audio band. Tailored, gradual 1st order filter x3 band processing achieves a natural waveform without the need for conventional output filters.
The D-10X has a clean, understated design finished in brushed aluminum and comes supplied with the matching RD-29 aluminum remote control. The front-panel fluorescent display has a zoom mode for easy reading from the ideal listening position. The D-10X is already available at a suggested retail price of $16,495.
