Luxsin X8 DAC Headphone Amplifier Preamplifier DSP WiFi Bluetooth 5.1 8xCS43198 32bit 768kHz DSD512
The Luxsin X8 is a high-end all-in-one audio solution designed for demanding audiophiles, combining the functions of a DAC, headphone amplifier, and preamplifier. As such, it combines a powerful digital-to-analog converter, a headphone amplifier capable of driving even the most power-hungry headphones, advanced DSP with AI-assisted equalization, an intuitive touchscreen, and comprehensive connectivity in a high-quality CNC-machined aluminum chassis. The goal of the X8 is to provide a customizable, detailed, and immersive listening experience for any modern desktop or home studio audio setup.
Luxsin X8: 8 CS43198 DACs in dual mono parallel architecture
The Luxsin X8 features an ambitious DAC architecture based on eight Cirrus Logic CS43198 chips mounted in a dual-mono configuration with four DACs per channel. This approach allows for complete separation of the left and right channels (power supply, circuits, and signal paths), which significantly reduces noise and crosstalk and improves dynamics and signal-to-noise ratio. Each DAC is protected by dedicated shielding to minimize interference and optimize the reproduction of fine details. The X8 supports high-resolution playback up to 32bit 768kHz PCM and DSD512, ensuring ultra-precise conversion and a stable, deep sound image.
Luxsin X8: Powerful headphone amplifier
The amplification section of the Luxsin X8 is designed to deliver generous power and refined musicality. Thanks to optimized amplification using multiple OPA1612 operational amplifiers and TPA6120A2 high-current drivers, the device delivers up to ≈4800mW per channel (on balanced outputs) with very low distortion and excellent linearity. Three headphone outputs are available: balanced XLR4, balanced 4.4mm, and single-ended 6.35mm, ensuring compatibility and power for a wide variety of headphones and earphones. An intelligent automatic impedance detection system adjusts the optimal gain according to the connected headphones, for consistently accurate control.
Luxsin X8: Wi-Fi DSP & AI-assisted equalizers
One of the X8's strengths is its integrated DSP engine based on a dual-core HiFi-5 DSP + ARM STAR architecture, with sufficient computing power for advanced real-time audio processing. The X8 offers AI-assisted parametric equalization, allowing you to automatically adjust the sound signature or correct the frequency response according to your preferences via voice or text commands. A vast integrated database contains more than 2500 headphone profiles, facilitating personalized equalization tailored to each model. All these functions can be controlled from the screen, a mobile app, or a web interface.
Luxsin X8: Smart and flexible control
The Luxsin X8 also stands out for its advanced management via the Luxsin Controller ecosystem, offering unmatched flexibility of use: the device can be controlled not only from its built-in touchscreen, but also via mobile apps for Android/iOS, web control from a browser on Windows or macOS, and even with an optional infrared remote control. This ability to control it from different devices makes it easy to adjust all audio settings—equalization, custom PEQ profiles, DSP settings, volumes, and more—without being physically in front of the device. The X8's firmware is designed to be updated locally or online, ensuring that the user experience evolves and improves over time. The Luxsin Controller mobile app makes it particularly easy to select headphone profiles and adjust equalization, making sound customization more intuitive and accessible.
Luxsin X8: Touchscreen & VU Meters
The Luxsin X8 features a 4-inch color touchscreen (960 × 480), providing a rich and intuitive visual interface at the center of the device. This screen facilitates access to all system functions and real-time playback level monitoring. While listening, various VU meters, spectrum analyzers, or file resolution information can be displayed with customizable styles, making it both functional and aesthetically pleasing to use.
Luxsin X8: Independent Power Supplies
To ensure optimal audio performance, the Luxsin X8 employs a fully separated linear power supply for digital and analog circuits. This separation reduces interference and noise coupling, providing a clean electrical foundation that improves clarity, soundstage depth, and dynamics. The system incorporates voltage and current sensors to monitor power in real time, as well as an adjustable dual analog voltage design (12V/15V), increasing flexibility for different types of audio loads.
Luxsin X8 Overview
The Luxsin X8 has extensive connectivity, allowing it to adapt to a wide range of uses and audio configurations, with USB-B, USB-C, coaxial, optical, and IIS inputs compatible with high resolution up to 32bit 768kHz and DSD512, RCA and XLR analog outputs that can be used in DAC or preamplifier mode, as well as multiple balanced and unbalanced headphone outputs for maximum compatibility. 12V trigger ports complete the package, making it easy to integrate the X8 into a controlled or automated hi-fi system.
