The Luxsin X9 is a high-end headphone amplifier/DAC that combines state-of-the-art audio technology with refined design. With a powerful 4000 mW output at 32 ohms, precise R2R volume control, an innovative headphone equalizer, and extensive connectivity, it offers an exceptionally detailed, dynamic listening experience—tailored for audiophiles with the highest standards. And it is ready for more than 2,500 different headphone models...

Prepared for 2500 Headphones
With the brand-new X9, Luxsin presents a high-end headphone amplifier that makes audiophile hearts beat even faster. As a sister brand to Eversolo, Luxsin Audio stands for compact, high-performance desktop audio devices developed specifically for audiophile users. In Germany, Luxsin, like Eversolo, is distributed exclusively by audioNEXT in Essen. Designed for discerning sound enthusiasts, the X9 combines powerful hardware with an elegant, functional design. An innovative operating concept based on a 4-inch 1080p touchscreen allows for intuitive control while providing visual feedback through customizable VU meter styles. An integrated standby mode ensures energy efficiency, while the display can be deactivated if desired. The Luxsin X9 delivers enough power to drive even power-hungry headphones without compromise. Over 2,500 supported headphone models and continuous updates promise future-proof compatibility. Thanks to integrated HP-EQ technology, the sound profile is precisely tuned to the desired target curve—for a natural and detailed listening experience that suits almost any taste.

Technical Excellence Meets Sonic Precision
At the heart of the Luxsin X9 is a fully balanced circuit design with R2R volume control and a channel accuracy of 0.1 dB—for precise balance without audible distortion. Ultra-low ripple suppression of just 40 nV and a star-shaped power distribution system strictly separate digital and analog signal paths. Signal processing is handled by the AK4499EX DAC. The result: A pitch-black background against which timbres unfold as if on an endless stage. With an impressive THD+N value of -120 dB, the Luxsin X9 delivers extraordinary purity and clarity. All processing steps—from digital signal processing and I/V conversion to the power stage—are carried out entirely in differential circuits. These are ideal conditions for an absolutely clean and dynamic sound image.

Intelligent Features for a Personalized Listening Experience
A special highlight of the Luxsin X9 is the Dynamic Negative Feedback (DNF) technology. The combination of OPA1612 and TPA6120A2 reduces harmonic and intermodulation distortion to a minimum, ensuring an unadulterated, transparent playback. The integrated crossfeed function provides a speaker-like listening experience with natural spatiality and reduces listening fatigue—ideal for long sessions. The precisely adjustable soundstage also allows for finely tuned perception of depth and width. Innovative impedance detection technology automatically measures the resistance of the connected headphones and intelligently adjusts the output power—for a personalized and consistently optimal audio experience. Supported by a fast RTOS operating system, the device starts up instantly and allows for continuous improvement of the user experience via OTA updates.

Design, Ease of Use, and Connectivity at the Highest Level
The Luxsin X9 is also impressive on the outside: the CNC-machined aluminum housing not only ensures efficient heat dissipation but also stands out with its diamond-cut edges. The thoughtful design also improves the tactile feel during touch operation. An included remote control further expands the range of applications. The variety of connections leaves nothing to be desired: HDMI ARC for TV audio, optical and coaxial inputs, USB-B for computers, USB-C for mobile devices, and analog connections including subwoofer-out offer maximum flexibility for any environment. As a headphone amplifier and preamplifier in one, the Luxsin X9 delivers a pure, dynamic sound with precise signal control. This makes it the perfect control center for demanding music lovers who do not want to make any compromises—neither in sound nor functionality.
