Luxman DA-07X DAC

Luxman DA-07X DAC

LUXMAN’‘s latest D/A converter, featuring multiple inputs and outputs, designed to be the core of an advanced audio system for digital sound sources, fully compatible with the latest generation of digital formats.

A wealth of research and development went into our D-07X SACD/CD player, released in 2022, highly acclaimed by reviewers and die-hard disc enthusiasts. Hence, we are proud to introduce its logical successor, the DA-07X, our new high-end D/A converter.
By removing disc transport and playback protocols, we were able to brush up functionality, sound quality and performance to create a genuine, state-of-the-art DAC product. In today’s music distribution market, streaming has become the rightful heir to CDs, a physical medium that has been around for over 40 years, streamed audio is a genuine, contemporary source for today’s music lovers. Streaming services are attracting a great deal of attention, appearing one after another and offering excellent sound quality and ease of use to satisfy modern audio enthusiasts. As the techniques employed to supply digital sound sources develop, standalone D/A converters are becoming increasingly important to listeners, just as valid as conventional components, such as amplifiers and speakers.
The DA-07X inherits the slim format of the DA-06, a hit standalone DAC model released in 2013, however this model is equipped with the cutting-edge digital processing capabilities inherited from our recent flagship SACD/CD players, the D-10X. The DAC mother board uses the same top-of-the-range BD34301EKV DAC chips from the ROHM “MUS-IC” series featured in our D-10X and D-07X players, also in dual mono configuration. Via a proprietary USB input, the unit provides a powerful, high resolution digital signal processing environment, supporting encoding rates up to 768kHz/32 bit for PCM signals and 22.5MHz for DSD data and comprehensive decoder functionality that fully supports advanced MQA encoding. The analog output section employs fully balanced current/voltage conversion routines that independently process the differential outputs of each DAC chip, operating in dual mono mode, and high-quality, discrete buffer circuitry that also serves as an LPF stage, powerfully driving next-stage components.
This combination achieves a wonderfully smooth and richly dynamic sound. The exterior combines a finely finished, blasted white front panel with a large status window housing a newly adopted, high-definition OLED display, creating a pleasing and precise user interface. The D-07X rises to the challenge of being a next generation USB equipped D/A converter, realizing an inspiring digital audio playback experience. Employing the latest digital processing technology, this model confidently handles a wide range of digital inputs and offers carefully crafted analog output circuitry, casting itself a central role in forward-looking audio systems.

Functions / Digital circuitry
- In addition to a USB input for connection to a network transport unit (NT-07) or
PC/Mac, there are variety of digital input terminals, including 2 coaxial, 2 optical,
and 1 balanced XLR (AES/EBU)
- Balanced XLR output terminals and wide-pitch RCA output terminals that can
accommodate high-performance analog line cables equipped with large
connectors
- Equipped with the top-of-the-range BD34301EKV DAC chips from ROHM’ s
“MUS-IC” series in dual mono configuration
- Supports digital formats up to 768kHz/32bit PCM and 22.5MHz DSD data over
USB and up to 192kHz/24bit for PCM and 2.8MHz for DSD(DoP) over S/PDIF.
- High-precision, low-jitter, ultra-low phase noise clock module eliminates
inaccuracies at the oscillation frequency
- Filter switching function allows selection of simulated analog output response
(PCM/MQA BYPASS: 2 digital filter modes, DSD: 2 analog filter modes)
- Various low jitter functions shut down unnecessary signal paths, improving the
quality of the analog outputs
- Digital output off function closes unused digital routing, further enhancing
analog output quality
- Front panel output phase switching function offers analog output compatibility
for next stage components (both unbalanced and balanced outputs are
switchable)
- DD converter function allows through-routing of digital input signals to digital
outputs (1 path each for coaxial and optical outputs, PCM maximum rate is
192kHz/24bit at PCM)

Analog circuitry
- High-quality, discrete buffering with fully balanced output architecture (4 identical
amplifiers slaved to the differential outputs of the dual DAC chips)
- Highly regulated power supply environment, large OI type power transformer and
independent regulators for each circuit block with paired custom-made 10,000uF filter
capacitors
- Abundant use of LUXMAN’s traditional non-angled circuit board tracing, high purity
OFC internal wiring, original custom components, etc.

Chassis / Accessories
- A slim build that comfortably integrates with our NT-07 network transport and
P-750MKll headphone amplifier models
- Large, high-resolution OLED display with 4-stage dimmer and auto-off function
displays a variety of information about device status and incoming audio data
- Shielded chassis structure that thoroughly blocks digital and EM interference
・Extra-thick steel chassis base plate (2 sheets, total thickness 3.6mm) that contributes
to increased ground mass and improves the rigidity of the case
- Density gradient equipped cast iron feet protect delicate music signal handling from
unnecessary external vibrations
- Inverted AC inlet mounting allows the entire terminal to support the weight of a heavy
IEC cable
- Original, high-quality music playback software, LUXMAN Audio Player (compatible
with Windows/Mac, distributed free of charge on our website)
- Dedicated driver software compatible with BulkPet transfer, that achieves high
stability by levelling the transmission load over a USB connection to PC or Mac
(Windows/Mac drivers available free of charge on our website)
