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.
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.
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.
