The Luxsin brand introduces the Luxsin X9 stationary headphone amplifier with a digital-to-analog converter, designed by the same team behind Eversolo Audio products. Both brands are owned by Zidoo Technology Co. Ltd., known for their multimedia players.
The company states that the new Luxsin Audio brand will focus on desktop audio, and the Luxsin X9 is a worthy step in this direction. The Luxsin X9 is a headphone amplifier and DAC that can also be used as a preamplifier. It meets the highest standards by relying on well-thought-out concepts, the latest technologies, and high-quality components. The model can decode digital streams in PCM format with resolutions up to 32-bit/768kHz and DSD up to DSD512.
Signal processing in the Luxsin X9 is achieved through DSP. Profiles with corresponding correction curves are available for a wide range of headphones. The Luxsin X9 can also automatically measure the impedance of headphones immediately after they are connected and then adjust the output stage to an optimal level. This is an original feature of the model. The Luxsin X9 is equipped with an HDMI port with ARC support. The analog output stage of the Luxsin X9 uses a volume control based on the R2R resistive matrix. For headphone connection, options include a 6.35mm unbalanced connector, as well as balanced outputs Pentaconn 4.4mm and 4-pin XLR.
A New Benchmark in Desktop Audio
The Luxsin X9 sets a new standard for what a desktop component can be. Designed for audiophiles and high-definition enthusiasts who do not compromise, it combines a benchmark-level DAC, powerful headphone amplifier, and full-featured preamplifier in an elegant enclosure. Powerful patented technologies are hidden behind a 4-inch fully laminated touchscreen display, providing listening convenience that is as easy to operate as it is incredibly pleasing to hear.
Flagship of Engineering Excellence
The X9 motherboard has ultra-low pulsations of only 40mV, achieved by a star-shaped voltage distribution scheme that clearly separates digital and analog power channels, eliminating cross-contamination that can degrade the quality of less sophisticated models. The flagship AKM AK4499EX DAC is stabilized by the TI BB OPA1612 operational amplifier, providing super-stable reference voltage for processing signals with exceptional precision. The -120dB volume level speaks for itself: this device is created without compromise.
True Balance - From Input to Output
The fully balanced, differential architecture of the X9 works from start to finish. Decoding the input signal is handled by the AK4499EX DAC, OPA1612 IV conversion, low-frequency filtering, R2R volume control, dynamic feedback, and TPA6120A2 headphone amplifier cascade - all elements of the signal chain work in perfect balance. The result is uncompromising sound quality: unmatched clarity, precision, and depth while maintaining all the benefits of balanced design.
Dynamic Negative Feedback (DNF)
The Luxsin patented technology with dynamic negative feedback, implemented by a combination of OPA1612 and TPA6120A2, actively and continuously reduces harmonic and intermodulation distortions. The result is a cleaner and more transparent sound with minimal coloration, enhancing tonal purity and dynamic expressiveness while faithfully reproducing every sound detail for an exquisite and captivating listening experience.
Precision Volume Control
The R2R volume control scheme, consisting of high-precision components in a fully balanced configuration, allows for adjusting the balance of left and right channels with an accuracy of up to 0.1 dB. This level of precision ensures distortion-free attenuation and absolute channel matching - this control is crucial for critical listening.
HP-EQ - Hardware Optimization of Headphones
The HP-EQ system in the X9 performs real-time hardware equalization based on the measured frequency characteristics of your specific headphones, providing sound characteristics closest to the Harman curve. With a database of over 2500 headphone models and support for user EQ profiles with one-click switching, optimal listening without fatigue has never been more accessible and accurate.
Headphone Impedance Self-Check
The proprietary impedance detection system automatically measures the impedance of connected headphones via 6.35mm or 4.4mm ports, then sensibly recommends the optimal output gain setting. The Luxsin bypass detection technology ensures that this measurement is performed without compromising sound quality.
Full-Color 1080P Touchscreen
The 4-inch full-color 1080P touchscreen display of the X9 provides a bright high-definition interface that makes navigating all functions intuitive and visually appealing. If you want nothing to distract you from listening to music, the display can be completely turned off for a more comfortable listening experience. The device also automatically switches to standby mode when no signal is present, ensuring efficient operation in automatic mode.
Visible Rhythm - Dynamic VU Meters
The dynamic VU meter captures all subtle sound fluctuations in real-time, providing the X9 with a visual impulse that matches its sound characteristics. Several types of VU meters are available, allowing you to customize the display according to your mood and settings.
Diamond-Cut Design
The front panel features a diamond-cut bevel angled at 15°. This detail is as functional as it is beautiful. The tilted chassis provides ergonomic touch control when listening while seated, while the fully processed CNC aluminum housing ensures excellent heat dissipation, structural rigidity, and a premium-class refined appearance that sets it apart from competitors.
Intelligent Control and OTA Updates
The X9 operates on an advanced real-time operating system, providing stable and responsive control over all inputs and outputs. It supports infrared remote control, as well as wireless control via smartphone or computer. Built-in OTA updates mean the X9 can receive performance enhancements and new features without any physical intervention - a device that improves over time.
Crossfeed and Adjustable Soundstage
Digital crossfeed provides natural sound dynamics, reducing listener fatigue during long listening sessions. Users can also adjust the depth and width of the soundstage themselves - both are implemented digitally to ensure accuracy without distortion or tonal coloration inherent in analog processing.
