The FiiO KA11 is a portable DAC based on a CS43131 DAC chip for digital-to-analog conversion, along with SGM8262 operational amplifiers to amplify the signal. This compact portable DAC supports high-resolution streams up to PCM 32bit 384kHz and DSD256, and is capable of delivering up to 2x 245mW into 16 ohms. It is compatible with many devices via plug and play (Mac OS, Windows, iOS and Android) and also supports gaming consoles (PS5, Switch) thanks to UAC2.0 and UAC1.0 protocol compatibility. In addition, the KA11 can be controlled via the FiiO Control application available on Android and iOS. To ensure stable signal transmission and protect it from interference, FiiO has chosen to use palladium-plated OFC copper conductors for the cable of its KA11 portable DAC.

The KA11 chipset, composed of a CS43131 DAC chip, and an independent SGM8262 op-amp, delivers high-quality sound reproduction. This is achieved thanks to support for high-resolution PCM 32bit 384kHz and DSD256 streams, as well as amplification up to 2x 245mW @ 16 ohms and 2x 200mW @ 32 ohms, all while maintaining THD+N below 0.0006% and an SNR of 125dB.


The KA11 is plug-and-play compatible with Windows, Mac OS, Android and iOS operating systems. Moreover, its dual UAC2.0 and UAC1.0 operating modes make it compatible with Nintendo Switch and PS5 consoles.
The KA11 can be controlled via the FiiO Control application available on Android and iOS. This allows for volume adjustment, RGB display control, and the use of digital filters.


The cable used in the KA11 features palladium-plated OFC copper conductors for interference-free signal transmission.
