Overview

Pure sound so you can enjoy your music with complete peace of mind

Designed to meet the demands of audiophiles and lovers of high-fidelity sound, the Luxsin X9 is a headphone amplifier, Hi-Res DAC and Hi-Fi pre-amp that harmoniously combines hardware power, elegant design and features to deliver pure, captivating sound. Capable of handling high-definition music up to 32 bit / 768 kHz, DSD512, its in-house-developed innovations offer a unique immersive listening experience, while its intuitive software ensures simple and efficient use.

Exceptional processing accuracy

The X9 's unique HP-EQ technology applies hardware equalisation adjustments in real time according to the frequency response of each headphone. This results in a sound signature perfectly aligned with the ideal Harman curve, delivering an audio experience tailored to the preferences of a wide range of listeners. It also supports custom equalisation profiles with one-click change, thanks to a growing database of over 2,500 headphone models.

The Luxsin Audio X9 benefits from audiophile-quality components. Its AK4499EX DAC is combined with its own AK4191EQ delta-sigma modulator. This stage uses two oscillators to ensure very high-precision playback of Hi-Res music at up to 32 bit / 768 kHz, as well as DSD512 streams.

Designed with a fully-balanced R2R volume control circuit made from high-precision components, it allows rechannel balance adjustments with exceptional accuracy of 0.1 dB, ensuring precise, distortion-free audio performance.

Luxsin Dynamic Negative Feedback technology and extended connectivity

Luxsin Dynamic Negative Feedback (DNF) technology, combining the OPA1612 and TPA6120A2, significantly reduces harmonic and intermodulation distortion, ensuring clearer, more transparent sound with minimal coloration, while faithfully reproducing every sonic detail. This advanced design enhances tonal purity and dynamic expression, providing a refined and immersive listening experience.

The X9 is equipped with a wide range of connectivity options, including HDMI ARC, optical, coaxial and analogue inputs, USB-B/USB-C ports, 12V trigger ports and two subwoofer outputs. This enables seamless integration into a variety of audio configurations, offering optimum flexibility for home and professional audio environments. As a reference DAC, headphone amplifier and preamplifier, the X9 offers exceptional signal control and dynamic audio performance, setting a new standard in desktop audio.

Finally, the X9 is equipped with several dynamic VU-meters displayed on its large touchscreen that visually capture every subtle fluctuation in the sound, providing a graphical representation of the sound in real time. With a range of VU meter styles, users can personalise their visual experience while enjoying their music.

    Um amp full of functionality!

    This amp is just excellent, a lot of connectivity, easy to use, it is connected to my PC via a USB-B cable provided, I use a Focal Clear MG headphone connected in XLR4, it passes in DAC mode beyond 192khz which is very good quality, but the best is when you stay at 192khz/32bits and use the equalizer with the Harmans profiles for your headphones if they're referenced in the software (2,500 headphones referenced anyway), it produces a sound that's so lively, punchy, clean, crisp, all at the same time...

    The menu is as fluid as a smartphone, easy to use even for someone who doesn't necessarily know their way around, there are also lots of expert settings, the impedance of the headphones is automatically recognised when you plug them into a 4.4mm or 6.35mm jack, with XLR4 you have to adjust manually but nothing too complicated.

    Well done to Luxsin, a sister brand of EverSolo!
