Flagship dual DACs For excellent sound

The KA5 features dual Cirrus Logic CS43198 DACs, known for their efficiency and their ability to sound good with a wide variety of music, to give you a serious upgrade to your sound.

High-Res decoding Listening to the heart of music

The KA5 supports up to 32bit/768kHz PCM and DSD256 decoding, allowing you to really dig into and listen to the heart of your music, no matter what device you may have it connected to.

Serious components Serious power

For better audio performance, the KA5 utilizes a 6-layer immersion-gold PCB as well as high-performance ultra-low noise op amps for powerful, robust sound.

Bold ruggedness Highly capable

The aggressive lines of the KA5 give it a bold look, while the carefully designed texture makes it a joy to handle. The dual outputs on the right side of the KA5 hint at its powerful capabilities.

*3.5mm output supports SPDIF output. After enabling the SPDIF output in the settings menu, the USB audio signals can be converted to SPDIF signals. Connect the KA5 to a higher-end external decoder to set up a better audio system.

Flexible local operating system

The OLED display and physical buttons make navigating the settings menu and looking at the playback display more straightforward and intuitive. In addition, the KA5’s built-in MCU processor handles complex operations with ease, further making the KA5 a joy to use.

*The KA5 can only be controlled through the FiiO Control app on an Android device.
