Luxsin X8 DAC, Preamplifier & Headphone Amplifier

The X8 represents Luxsin's evolution in high-fidelity audio engineering. Building on the acclaimed X9 platform, this intelligent DAC and preamplifier combines refined sonic architecture with enhanced hardware design and streamlined software. The X8 integrates proven features from its predecessor while introducing thoughtful innovations developed through extensive user feedback and real-world refinement. Engineered for discerning listeners who demand reference-grade performance, stability, and intuitive control in a single component, the X8 delivers sophisticated audio reproduction with the reliability Luxsin has established as its hallmark.

Parallel DACs | 8 x CS43198

The X8 features eight Cirrus Logic CS43198 DAC chips in a true dual-mono parallel architecture, with four DACs operating in parallel per channel. Left and right channels are fully independent in power supply, circuit layout, and signal path, minimizing crosstalk and interference. The parallel analog outputs are precisely summed to reduce noise and improve dynamic range, signal-to-noise ratio, and low-level detail, resulting in stable imaging and clear spatial presentation. A dedicated high-speed data buffering and distribution circuit ensures all DACs operate within the same reference clock domain, maintaining precise synchronization and preventing timing mismatch.

DAC Dedicated Shielding

Digital Audio Core

HP-EQ System

HP-EQ is Luxsin's proprietary acoustic technology that performs hardware level EQ calibration, aligning your headphones' frequency response precisely with the Harman curve or other preset target curves. unlocking multiple "personalities" from a single pair of headphones. With a growing database of over 2,500 headphone models, HP EQ delivers accurate, personalized audio matching for every listener.

The AI Era of PEQ

Comprehensive DSP Functions

• Crossfeed Simulates natural speaker listening by blending left and right channels, reducing ear fatigue and enhancing sound realism.
• Stereo Width Adjustment Freely control soundstage width from intimate to expansive, to perfectly match different music genres and personal  preferences.
• Tone Adjust Fine-tune the overall tonal character with intuitive controls, shaping the sound to match your listening taste quickly and easily.
• Loudness Intelligently compensates for low- and high-frequency details at lower volumes, ensuring balanced, full-bodied sound at any listening level.

Full-Interface Impedance Detection

The upgraded headphone impedance detection system now covers all output interfaces (XLR4,4.4mm, and 6.35mm) enabling precise impedance auto-detection and automatic matching of the optimal gain setting. Utilizing Luxsin’s proprietary bypass detection technology, the system operates completely isolated from the main audio path, guaranteeing absolutely no impact on sound purity. Users enjoy both accurate impedance matching with smart gain adjustment and un-compromised high-fidelity audio quality.

Upgraded Output Power

The X8 employs a optimized headphone amplifier design using multiple OPA1612 op-amps and TPA6120A2 high-current drivers to independently drive each channel, delivering a powerful output of L+R ≥ 4800 mV + 4800 mV with extremely low distortion and high linearity. It effortlessly drives even the most demanding flagship headphones, offering strong dynamics, fast transients, and precise detail retrieval.

Variable Voltage Linear Power Supply

Adopts a fully separated linear power supply, with digital and analog circuits independently powered. This design isolates noise coupling and interference between circuits from the source, significantly enhancing sonic purity, background darkness, and laying a stable, clean power foundation for overall sound quality. The system integrates multiple voltage and current monitoring sensors for real-time power supervision. It also supports an adjustable dual analog voltage design (12V and 15V), further improving the flexibility and controllability of the power system.

Signature Exterior Design

The X8 continues Luxsin’s classic design language, featuring a 4.0-inch 1080P(960×480) full-color touchscreen that delivers sharp, detailed visuals and a smooth, intuitive user experience. Its front panel is tilted at a 15° ergonomic angle, enhancing visibility and ease of operation in daily use. Crafted from a solid CNC-machined aluminum chassis, it offers both premium tactile feedback and exceptional thermal dissipation

User Settings Memory

Automatically saves independent settings for each output port, including key parameters such as volume, PEQ, sound effects, and crossfeed. When switching outputs, the system instantly recalls the corresponding configuration, eliminating the need for readjustment and delivering a true plug-and-play experience.

Luxsin Controller

The X8 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. 

Versatile Audio Connections

The X8 is equipped with a range of digital audio input interfaces. including USB-B/C, Optical, Coaxial, and IIS, to accommodate various source devices. The IIS input supports up to eight custom configurations, ensuring compatibility with multi-type digital sources from different brands. It also features 12V Trigger in/out terminals, enabling seamless integration into existing audio systems for smoother device synchronization and automated control, making the entire system easier and more efficient to operate.

Features

• Eight-DAC Parallel Architecture: The device utilizes eight Cirrus Logic CS43198 DAC chips (four per channel in a true dual-mono configuration) to minimize noise and improve dynamic range and detail retrieval.
• AI-Assisted EQ Tuning: A standout feature is the "world's first" AI-assisted personalized EQ system, which allows users to adjust the sound profile using simple voice or text commands via a mobile app or web interface, making professional-grade tuning accessible to a wider audience.
• Powerful Headphone Amplifier: It features an amplifier design with OPA1612 op-amps and TPA6120A2 high-current drivers, delivering significant power (over 4.8W per channel at 16 ohms balanced) capable of driving demanding flagship headphones.
• Automatic Impedance Detection: The X8 automatically detects the impedance of connected headphones across all output ports (4-pin XLR, 4.4mm balanced, and 6.35mm unbalanced) and matches the optimal gain setting without affecting the audio path.
• Versatile Connectivity: It includes a wide range of digital inputs, such as USB-B/C, Optical, Coaxial, and IIS, and analog outputs (RCA and XLR) to accommodate various source devices and system integrations.
• High-Quality Build & Control: Housed in a CNC-machined aluminum chassis with an ergonomic 4-inch color touchscreen, it can also be controlled via mobile apps (Android/iOS), a web browser, or an optional IR remote.
