The player’s digital circuits incorporate a Burr-Brown PCM1792A D/A converter, supporting not only CD and SACD playback, but also PCM data up to 32-bit/384kHz and DSD data up to 5.64MHz via the USB input. This is a far higher specification than that required by most current music formats, ensuring the D-06u is fully equipped for future advances in ultra-high-definition digital sound.
The D/A converter chip combines with Texas Instruments’ TAS3152 32-bit digital signal processor, which upsamples PCM data to 384kHz and supplies three digital filter options for PCM, plus a pair of tone settings for DSD. Jitter (digital distortion) is reduced in three ways: for USB signals, by the dedicated DSP via asynchronous communication; for CD and S/PDIF signals, by the embedded DAIR high-precision clock; and for SACD signals, by a dedicated jitter reduction chip. In addition, a low phase noise clock module improves the accuracy of the entire signal transmission.
The D-06u’s analogue output stage is of the highest quality, utilising audiophile-grade components in a fully balanced configuration with a regulated, high-inertia power supply. Build quality is exemplary, as it is throughout the Luxman range, right down to the cast-iron, resonance-reducing feet. The player comes with dedicated ‘Luxman Audio Player’ software for PC/Mac, enabling a wide range of digital audio formats to play through the D-06u via the USB input, including FLAC, ALAC, WAV, AIFF, MP3, DSF and DSIDIFF.
