Luxsin Audio X9 headphone amplifier with DAC and Bluetooth

Luxsin Audio X9

The Luxsin X9 is a high-end headphone amplifier/DAC that combines cutting-edge audio technology with elegant design. With a powerful 4000mW at 32 ohms output, precise R2R volume control, an innovative headphone equalizer, and extensive connectivity, it offers an exceptionally detailed, dynamic listening experience – tailor-made for audiophiles with the highest demands.

The Luxsin X9 is a carefully engineered, high-performance desktop DAC and headphone amplifier. It uses AKM's top-of-the-line AK4499EX DAC and features a hardware-level headphone EQ that automatically optimizes the headphone frequency response – with support for over 2,500 models. Equipped with hardware-based crossfeed technology and audiophile-grade components, it guarantees exceptional sonic precision. The fully balanced headphone amplifier delivers an impressive output power of 4000mW at 32 ohms. In addition, the X9 features a wide range of input options, R2R relay volume control, Wi-Fi control, OTA updates, and HDMI-ARC for an intuitive and versatile user experience.

Ready for 2,500 Headphones

With the brand-new X9, Luxsin presents a high-end headphone amplifier that will make audiophiles' hearts beat even faster. As a sister brand to Eversolo, the Luxsin Audio brand stands for compact, powerful desktop audio devices specifically designed for audiophiles. 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 user interface based on a 4-inch 1080p touchscreen enables intuitive control while providing visual feedback thanks to customizable VU meter styles. An integrated standby mode ensures energy efficiency, while the display can be deactivated upon request. The Luxsin X9 delivers enough power to drive even the most demanding headphones without compromise. Over 2,500 supported headphone models and continuous updates promise future-proof compatibility. Thanks to the integrated HP-EQ technology, the sound is precisely tuned to the desired target curve – for a natural and detailed listening experience that suits almost every taste.

Technical Excellence Meets Sonic Precision

At the heart of the Luxsin X9 is a fully symmetrical circuit design with R2R volume control and channel accuracy of 0.1 dB – for precise balance without audible distortion. The ultra-low ripple rejection of just 40 nV and the star-shaped voltage distribution system consistently separate digital and analog signal paths. The AK4499EX DAC handles signal processing. The result: a deep black background against which timbres unfold as if on an endless stage. With an impressive THD+N value of -120 dB, the Luxsin X9 promises exceptional purity and clarity. All processing steps – from digital signal processing and IV conversion to the power amplifier – are consistently performed in differential circuits. Ideal conditions for an absolutely clean and dynamic sound.

Intelligent features for a personalized listening experience

A special highlight of the Luxsin X9 is Dynamic Negative Feedback (DNF) technology. The combination of the OPA1612 and TPA6120A2 reduces harmonic and intermodulation distortion to a minimum, ensuring pristine, transparent reproduction.

The integrated crossfeed function delivers a speaker-like listening experience with natural spatiality and reduces listening fatigue – ideal for long sessions. The precisely adjustable soundstage also allows for a finely tuned perception of depth and width. The innovative impedance detection technology automatically measures the resistance of the connected headphones and intelligently adjusts the output power – for a personalized and always optimal sound experience. Supported by a fast RTOS operating system, the device boots instantly and allows for continuous improvement of the user experience through OTA updates.

Design, ease of use, and connectivity at the highest level

The Luxsin X9 also impresses on the outside: The CNC-machined aluminum housing not only ensures efficient heat dissipation, but also impresses with its diamond-cut edges. The sophisticated design also improves the haptic feel of touch controls. A included remote control further expands the application possibilities. 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 a subwoofer out offer maximum flexibility for any environment. As a headphone amplifier and preamplifier in one, the Luxsin X9 delivers pure, dynamic sound with precise signal control. This makes it the perfect control center for discerning music lovers who don't want to compromise on either sound or functionality.
