Luxsin Audio X9 DAC/HEADPHONE Amplifier/ Pre Amp

Luxsin Audio is a specialist audio arm of EverSolo/Zidoo and offers some segment firsts along with quite incredible performance and a desirable bespoke spec list for a sub £1k model.

The Luxsin Audio X9 DAC Headphone and Pre Amplifier is a premium desktop audio solution built for audiophiles who demand uncompromising sound quality and versatility. Designed with precision and innovation at its core, the X9 integrates the flagship-grade AK4499EX DAC chip alongside the AK4191EQ modulator to deliver true reference-level audio performance.

Enhanced by TI OP1612 IV stages and ultra-precise Accusilicon femtosecond clocks, it achieves stunning clarity and definition. One of its standout features is the hardware-level HP-EQ, a headphone-specific equalization system that supports over 2,500 headphone models with factory-optimized profiles tuned to the Harman curve. With regular OTA updates, this database continues to expand, ensuring the X9 remains compatible with the latest headphones in the market.

Precision Engineering with Segment-Leading Features

Every aspect of the Luxsin X9 is crafted to meet the highest standards in sound engineering. Its fully balanced R2R relay volume control system provides exceptional precision, with 0.1 dB step accuracy and left-right channel balance adjustment. The smart headphone impedance auto-detection system measures the characteristics of the connected headphones and recommends the most suitable output gain setting.

Users can also customize the listening experience through digital crossfeed processing and adjustable soundstage width and depth. Comprehensive input and output options include USB-B and USB-C, coaxial, optical, RCA, and both XLR and RCA analog outputs. Dual subwoofer outputs and 12V trigger support further enhance its integration into high-end setups.

Touchscreen Interface and Seamless Control

At the heart of the Luxsin X9 is a 4-inch full-color touchscreen that provides intuitive control over all key functions. The interface is user-customizable and is supported by an automotive-grade real-time operating system that ensures smooth, responsive performance. For added convenience, users can operate the device via infrared remote control or through wireless devices like phones and computers.

Bluetooth 5.0 enables high-quality streaming, while OTA firmware updates ensure the system remains current with evolving features and enhancements. With a high-precision resistor network and ultra-low ripple linear power supply, the X9 delivers an extremely clean signal path. This helps eliminate unwanted background noise and enhances micro-detail reproduction in high-resolution recordings.

Premium Build and Exceptional Value

The Luxsin X9 is designed to look as good as it sounds. The chassis is CNC-machined from solid aluminum with diamond-cut edges, combining durability with refined aesthetics. Internally, the amplifier features audiophile-grade components including Ohno Continuous Cast (OCC) silver-plated cables and Dynamic Negative Feedback (DNF) circuitry, ensuring both signal integrity and adaptive performance.

For headphone users, the X9 offers a wide range of outputs including 4.4mm balanced, 4-pin XLR, and 6.35mm single-ended options. With features like HDMI ARC, dual subwoofer support, and a wealth of digital and analog connections, it functions equally well as a high-end headphone amplifier and a powerful preamp. For its price, the X9 sets a new benchmark in desktop audio performance and value.
