Luxsin X9

Pure Sound, Pure Serenity
Designed to meet the exacting standards of audiophiles and high-fidelity sound enthusiasts, Luxsin X9 seamlessly blends powerful hardware with a sleek, functional design to deliver pure and captivating sound. Innovative in-house developed features provide a uniquely immersive listening experience, while the intuitive software system ensures effortless and efficient operation.

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.

4.0-inch 1080P Full-Colour Touchscreen
Featuring a 4.0-inch 1080P full-colour touchscreen, it offers a vibrant, high-definition display for an intuitive and visually engaging user experience. The display can be turned off for a completely immersive, blackout listening experience, while the device automatically enters standby mode when no signal is detected, ensuring efficiency and convenience.

Visible Rhythm
The X9 features a dynamic VU meter that visually captures every subtle fluctuation in the audio, providing a real-time graphical representation of the sound. With multiple VU meter styles to choose from, users can personalize their visual experience while enjoying the music.

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.

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, delivering a refined and immersive listening experience.

Diamond-cut design
The diamond-cut bevel design of the front panel, set at a 15° incline, not only enhances its aesthetic appeal but also improves ergonomic touch control. The full CNC-machined aluminium chassis ensures excellent heat dissipation, durability, and a sleek, elegant appearance.

Audiophile-grade audio components
To achieve ultimate sound quality, every component has been meticulously chosen. This includes premium red WIMA capacitors, gold-plated aluminium 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 (OCC) 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. As a reference-grade DAC, headphone amplifier, and preamplifier, the X9 delivers exceptional signal control and dynamic audio performance, setting a new standard in desktop audio.
