FX-Audio is a Chinese audio electronics brand operated by Shenzhen Feixiang Digital Technology Co., Ltd., based in Shenzhen, China. Founded in 2011, the company specializes in compact, affordable HiFi components aimed at budget-conscious audiophiles, including Class D digital integrated amplifiers, tube preamplifiers, headphone amplifiers, phono stages, Bluetooth audio receivers, and digital-to-analog converters.

The brand built its reputation in the international audiophile community through products like the D802 fully digital integrated amplifier, which gained traction in online HiFi forums for delivering performance at a fraction of the cost of larger-name competitors. Other widely discussed models include the DAC-X6 desktop DAC/headphone amplifier and a series of small tube buffer preamps that have become popular entry points for listeners experimenting with tube sound.

FX-Audio products are distributed globally through specialty audio retailers such as Shenzhenaudio, Audiophonics, and Parts Express, as well as marketplaces like Amazon and AliExpress. The brand is primarily known in the desktop HiFi and personal audio space rather than professional or instrument-related music gear.

FX AUDIO has 2 products cataloged on Equipboard, including Preamps and Audio Interfaces.
