HP-EQ
The X9’s unique HP-EQ technology applies real-time hardware-level EQ adjustments based on each headphone’s frequency response. This enables a sound signature closely aligned with the ideal Harman curve, providing an audio experience that resonates with a wide range of listener preferences. It also supports custom EQ profiles with one-click switching, backed by a growing database of over 2500 headphone models.
Precision Perfected
Engineered with a fully balanced R2R volume control circuit composed of high-precision components, it enables left-right channel balance adjustments with exceptional accuracy of 0.1dB, ensuring precise and distortion-free audio performance.
Headphone Impedance Self-Check System
Luxsin’s self-developed impedance detection system automatically measures the impedance of connected headphones via the 6.35mm or 4.4mm ports and intelligently recommends the most suitable output gain setting. Utilizing advanced bypass detection technology, this system ensures precise impedance measurement with zero impact on sound quality.
True Flagship
With an ultra-low ripple of just 40nV, the motherboard features a star-shaped voltage distribution circuit that cleanly separates digital and analog power paths. The AK4499EX DAC is stabilized by an OPA1612 op-amp, providing an ultra-stable reference voltage for highly accurate signal processing. With a THD+N of -120dB, the system delivers outstanding clarity, resolution, and dynamic range.
Crossfeed and Adjustable Soundstage
The X9 features advanced digital crossfeed for a natural, speaker-like sound, reducing fatigue during long sessions. Users can also adjust soundstage depth and width, with both features implemented digitally to ensure precise control without the distortion or coloration typical of analog solutions.
True Full Balance
Every stage, from signal input decoding and AK4499EX DAC to OP1612 IV conversion, LPF filtering, R2R volume control, dynamic feedback, and the 6120A2 headphone amplifier, is powered by a fully differential balanced circuit. This design ensures uncompromising audio performance, delivering unparalleled sound clarity, precision, and depth.
4.0-inch Full-Color Touchscreen
Smart Control
The X9 runs on an advanced automotive-grade RTOS, ensuring stable and efficient control of all I/O interfaces. It supports both infrared remote and wireless control via phone or computer, with OTA updates for easy firmware upgrades and ongoing performance improvements.
Dynamic Negative Feedback
Luxsin Dynamic Negative Feedback (DNF) technology, utilizing the OPA1612 + TPA6120A2 combination, significantly reduces harmonic and intermodulation distortion, ensuring a cleaner, more transparent sound with minimal coloration while accurately reproducing every sonic detail. This advanced design enhances tonal purity and dynamic expression.
Audiophile-Grade Components
To achieve ultimate sound quality, every component has been meticulously chosen. This includes premium red WIMA capacitors, gold-plated aluminum electrolytic capacitors, high-grade green non-polarized capacitors, numerous 0.1% high-precision low-temperature drift resistors, femtosecond clock, gold-plated connectors, Ohno Continuous Cast silver-plated cables, and TI BB's OPA1612 op-amps.
Headphone Amp and Desktop Preamp in One
The X9 is equipped with an extensive range of connectivity options, including HDMI ARC, optical, coaxial, analog inputs, USB-B/USB-C, 12V trigger ports, and dual subwoofer outputs. This allows for seamless integration into various audio setups, providing flexibility for both home and professional audio environments.
