EVERSOLO LUXSIN X9

The Luxsin Audio X9 positions itself as a benchmark in headphone amplification. It is not merely an amplifier, but a complete platform that combines technical precision, emotional engagement, and operational flexibility, the result of extensive research by audio engineers and software developers. Every detail is designed to ensure immersion and authenticity: the CNC-machined aluminum chassis guarantees solidity, durability, and efficient heat dissipation, while the front panel, angled at 15° with a diamond-cut finish, combines refined aesthetics and optimal ergonomics, making interaction with the device natural and intuitive.

At the heart of the Luxsin Audio X9 is a fully balanced architecture, from the AK4499EX DAC stabilized by OPA1612 to the final amplification stage with TPA6120A2, ensuring an interference-free signal path and unprecedented sonic clarity. Volume control relies on a balanced R2R circuit, allowing 0.1 dB fine adjustments with perfect channel balance, while HP-EQ technology analyzes the headphone frequency response in real time, adapting it to the Harman profile and enabling customization for over 2,500 models. The impedance self-diagnosis system automatically detects the connected headphones and suggests the optimal gain for flawless sound performance.

The user interface features a 4” Full HD 1080p color touchscreen, allowing easy navigation through settings and audio profiles, with the option to turn off the display for completely immersive listening. The automotive-grade RTOS operating system ensures stability and responsiveness in all operations, while remote control via smartphone, computer, or infrared remote, and OTA updates keep the device always up to date. The dynamic VU meter visualizes audio variations in real time, also offering different graphical styles to personalize the visual experience.

The Luxsin Audio X9 stands out for its versatility: it functions as a headphone amplifier, desktop preamplifier, and high-performance DAC, integrating seamlessly into professional or high-end audio systems. Its connectivity includes digital inputs HDMI ARC, USB-B/C, optical and coaxial; analog RCA inputs; balanced XLR and unbalanced RCA outputs; 12V trigger ports; and dedicated subwoofer outputs. It supports audio formats up to DSD512 and PCM 768kHz/32-bit, ensuring extremely faithful reproduction. Bluetooth 5.0 with AAC and SBC codecs provides stable wireless transmission without compromising audio quality.

Acoustic performance is exemplary: linear frequency response from 20Hz to 20kHz (±0.25 dB), dynamic range over 128 dB, distortion below -120 dB, and crosstalk beyond -117 dB on balanced outputs, delivering crystal-clear sound with a wide, detailed stereo image free of artificial coloring. Dynamic Negative Feedback (DNF) technology, combined with the OPA1612 and TPA6120A2, reduces harmonic and intermodulation distortion, producing a transparent, natural, and articulate sound. Every element of the Luxsin Audio X9 is designed for those seeking ultimate sonic purity and a definitive desktop platform capable of fully enhancing any headphone and audio source.
