Luxsin's second headphone amp, the X8, features their proprietary HP-EQ system that performs hardware level EQ calibration to match the headphone's frequency response precisely with the Harman curve. The X8 also 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. This DAC is also 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.
