About Fosi Audio products

Fosi Audio designs compact Class-D amplifiers, balanced DAC preamps, and desktop headphone gear for HiFi listeners who want clean sound without a rack-sized footprint. From the ZA3 dual-mode amp to the ZD3 DAC and K7 gaming DAC/AMP, the range focuses on useful I/O, solid measured performance, and approachable pricing.

Technology

Many Fosi power amps use Texas Instruments TPA3255 Class-D chips with audiophile-grade capacitors and inductors. Higher models add balanced XLR I/O, swappable op-amps, HDMI ARC on flagship DACs, and Bluetooth codecs like aptX HD.
