Reference device for versatile audio scenarios

The Luxsin X9 serves as a central interface in high-quality audio setups and functions optionally as a Digital-to-Analog Converter (DAC), headphone amplifier, or preamplifier. It processes digital and analog signals with the highest precision and outputs them to headphones or speaker systems accordingly.

Innovative HP-EQ technology for ideal sound

Through the integrated HP-EQ system, the device enables real-time hardware-level adjustment that matches the headphone's frequency response to the ideal Harman curve. With a database of over 2500 models and savable profiles, the sound signature can be individually optimized.

Fully balanced design and precise components

From the AK4499EX DAC to the R2R volume control, every section of the signal path is fully differential and balanced. High-quality components such as WIMA capacitors and precise OPA1612 operational amplifiers ensure extremely low distortion (THD+N of -120 dB) and a clear, precise sound image.

Intelligent impedance detection and control

When headphones are plugged in, the system automatically detects their impedance and recommends the appropriate gain. A modern real-time operating system (RTOS) and a 4.0-inch touchscreen ensure smooth operation, supplemented by the option of control via remote control or app.

Individual soundstage and visual feedback

In addition to the digital crossfeed function, which enables natural, speaker-like listening, the width and depth of the soundstage can be varied. A dynamic VU meter on the display visualizes the rhythm of the music in various styles.

High-quality casing and comprehensive connectivity

The CNC-milled aluminum casing with a diamond-cut front ensures durability and optimal heat dissipation. With connections ranging from HDMI ARC to USB-B/C to dual subwoofer outputs, the X9 offers maximum flexibility for home and professional applications.
