LUXMAN DA-07X

In the landscape of high-resolution audio and quality streaming, Luxman introduces the DA-07X, a USB digital-to-analog converter designed to maximize the potential of digital sources. This device combines cutting-edge digital technologies with refined analog circuits, delivering a deep and immersive musical experience. Thanks to its meticulous design, it serves as the heart of a modern audio system, transforming digital sound into a listening experience rich in detail and naturalness.

More than forty years after the introduction of the CD, the audio world continues to evolve: while physical media retain their charm, streaming and high-resolution digital formats are redefining sound quality standards. The DA-07X embraces this transformation, presenting itself as a standalone DAC without an optical drive but with expanded connectivity and superior sound performance. Compatible with computers, TVs, gaming consoles, and CD players, it offers flawless digital-to-analog conversion, utilizing Luxman’s most advanced technological solutions.

At the core of the DA-07X are ROHM’s "MUS-IC" BD34301EKV chips, employed in a dual-mono configuration to ensure optimal signal separation, delivering crystal-clear and precise sound. The DAC supports PCM signals up to 768 kHz and DSD up to 22.5 MHz via USB, also accommodating the MQA format for high-fidelity playback. Customizable filters for PCM and DSD data allow users to tailor the sound response to their listening preferences, while the MQA bypass function preserves the integrity of musical reproduction.

The clock management system employs two low-phase-noise modules, reducing jitter across all digital inputs, including asynchronous transmission via DSP for USB. The S/PDIF signal benefits from a high-precision DAIR clock, ensuring impeccable playback. Each input—USB, coaxial, optical, or AES/EBU—is designed to maintain the highest fidelity of the digital signal, ensuring extraordinary sound quality.

To minimize interference and optimize signal purity, the DA-07X features a PCB layout engineered to reduce distortion, while OFC copper wiring ensures smooth, lossless transmission. Internal shielding eliminates digital interference, and the power supply, based on three OI-core toroidal transformers, delivers a stable, fluctuation-free current. Custom capacitors contribute to excellent dynamic response, while the reinforced chassis with a steel base minimizes vibrations, supported by cast-iron isolating feet.

The front panel is equipped with a high-definition OLED display with four brightness levels and an automatic shutoff function. This intuitive interface allows real-time monitoring of key parameters such as sampling rate, bit depth, filter status, selected input, and MQA compatibility, providing precise control over settings.

In terms of connectivity, the DA-07X offers a comprehensive range of inputs, including USB, coaxial, optical, and AES/EBU, along with RCA and XLR analog outputs, ensuring maximum flexibility for any audio setup. Advanced functionalities, such as the ability to disable unused signal paths, direct digital conversion, and phase switching, further optimize sound performance. Completing the experience, the "Luxman Audio Player" software for Windows and Mac integrates four Bulk Pet modes, enhancing transparency and playback fluidity for a listening experience that captures every musical nuance.
