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.
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.
Impedance Auto-Detect 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.
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.
The X9 supports multiple flexible and convenient control methods, including
mobile device apps (Android/iOS), computer web‑based control (Windows/macOS), and an optional IR remote (sold separately). The device firmware supports both local and online updates, ensuring continuous optimization and an ever‑evolving user experience.
Visible Rhythm
The X9 features a vibrant 4.0-inch full-color touchscreen that transforms music into a dynamic visual experience. Choose from multiple VU meter styles and real-time spectrum displays, each responding instantly to changes in rhythm, dynamics, and frequency. From classic analog meters to modern spectrum visualizations, every listening session can have its own distinctive look.
Hearing Compensation
With Hearing Compensation, the Luxsin X9 measures your hearing sensitivity across different frequencies and creates a personalized compensation curve for each ear, helping you enjoy more detail, better balance, and a more natural listening experience.
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
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 aluminum chassis ensures excellent heat dissipation, durability, and a sleek, elegant appearance.
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, and TI BB’s OPA1612 op-amps.
