Core components that match your modern audio environment

More than 40 years have passed since the CD (compact disc) was introduced in 1982, and yet the format still remains a standard music distribution medium. Nowadays there are many high-quality streaming services that are attracting attention as next generation virtual sources that surpass the audio quality and convenience of CDs. As these modern digital sources become more diverse, D/A converters are expected to become fundamental universal audio components, as important as amplifiers and speakers for audio systems that connect the past, present and future. The DA-07X is a new D/A converter from LUXMAN, realized by removing the disc playback functions from our highly acclaimed D-07X high-performance SACD/CD player and thoroughly brushing up functionality, connectivity and sound quality performance as a standalone DAC device. This model accepts the digital outputs of all current audio devices, from network transports such as our NT-07, PCs and Macs, smartphones, TVs, game consoles, and even existing CD players, and maximizes the sound quality of audio signals with advanced digital signal processing systems and LUXMAN’s highly respected analog audio circuit technology. The DA-07X is a core component for a new era that perfectly matches modern audio environments centered on digital sound sources, allowing users to enjoy versatile music playback that suits their listening style.

Core components that match your modern audio environment

The latest digital technology and carefully designed analog circuitry combine to realize the ideal

The DA-07X brings together excellent high-end digital circuitry, inherited from our high-performance D-07X SACD/CD player, and an advanced analog output system. LUXMAN’s long-standing knowledge gained in amplifier development meets our newest digital technologies in order to realize expressive musicality that makes use of the abundant information contained in digital audio data, supporting the highest specifications of PCM and DSD formats.
The DAC block, which is the heart of the digital circuitry, relies on top-of-the range BD34301EKV DAC chips from ROHM’s “MUS-IC” series in a dual mono configuration. The USB input supports rates of up to 192kHz/24bit for PCM data and 2.8MHz for DSD (DoP). All inputs support full decoding of the MQA high-quality audio format. A new bypass function has also been included, making use of built-in digital filtering. The reference clocking system has two ultra-low phase noise clock modules with high precision and low jitter, reducing noise near the oscillation frequency to a minimum. To achieve even lower jitter, asynchronous communication by a dedicated DSP is used for the USB input and a built-in, high precision DAIR clock is used for S/PDIF signals. By adopting low jitter functions optimized for each input, we have surpassed our expectations of high-quality digital signal transmission. In addition, as a function that allows the listener to select a preferred sound reproduction standard, two digital filter modes are built in for PCM data (MQA bypass) and two analog filter modes for DSD data. The analog output stage, which determines the final grade of the component, has outstanding current/voltage conversion specifications, receiving the differential output of each BD34301KEV DAC chip operating in mono mode, just like LUXMAN’s high-end digital players, and high-quality buffer circuitry and fully balanced output architecture, further improving output audio signal impedance. Hence, the unit powerfully drives next-stage components, such as an integrated amplifier or control amplifier. In addition, we have adhered to a design philosophy that is thoroughly focused on every detail, such as a non-angled PCB tracing pattern that ensures smooth signal transmission, internal wiring with OFC cable, a shielded chassis structure that blocks digital noise and newly adopted silent relays.

Large capacity power supplies placed close to each circuit

The DA-07X features LUXMAN’s traditional, highly regulated power supplies to provide stable energy, with three separate OI core type transformers, regulation systems and bespoke filter capacitors for individual block. Such a high-quality power supply delivers powerful musical expression and a tranquil playback space.

High-definition OLED display

The DA-07X’s front panel is centered on a large, high-definition OLED display with a four-stage dimmer (with automatic shut-off function) that is easy to see from the listening position, displaying various information about signals and devices, such as input switching position, sampling frequency and bit depth. The bottom row also clearly displays filter and MQA status.

Stable AC inlet

The AC inlet’s structure has been improved to support the weight of heavy power cables by reversing the mounting, suppressing any movement of the power cable while maintaining a stable grip.

Highly rigid chassis and robust insulator feet

The slim chassis matches well with our network transport NT-07, featuring an extremely thick bottom chassis made of two steel plates (2mm+1.6mm thick), achieving high rigidity and a low center gravity. The cast iron insulator feet have density gradient built in, isolating the electronics and delicate music signal transmission from unnecessary vibrations.

Abundant input/output terminals to suit a variety of systems

The DA-07X is equipped with a variety of digital inputs including USB, two coaxial systems, two optical systems and AES/EBU (XLR) and also has wide-pitch RCA and XLR analog output terminals. A digital output off function that shuts down unnecessary signal paths to conserve processing bandwidth and a DD converter function that allows digital signals to be bussed through the unit unprocessed. There is also an output phase switching function (switchable on the front panel) for connections to particular next stage components.

LUXMAN’s original playback software

LUXMAN has also developed our own high-quality “LUXMAN Audio Player” music playback software for Windows/Mac, which supports four modes of Bulk Pet transfer that optimize the processor load between the source and the D-07X for improved transparency.
