KA13 - Portable USB DAC & Headphone Amplifier

The FiiO KA13 is a portable USB DAC and headphone amplifier designed to elevate the audio quality coming from phones, tablets, and computers without the need for bulky equipment. Despite its compact size, the KA13 integrates dual Cirrus Logic CS43131 DAC chips and dual low-noise SGM8262 op-amps, enabling precise and detailed high-resolution audio decoding up to 32-bit/384 kHz PCM and native DSD256. It offers both single-ended (3.5 mm) and balanced (4.4 mm) headphone outputs, making it versatile enough to drive a wide range of headphones and IEMs. The desktop mode can be activated to unleash up to 550 mW of balanced power, giving it desktop-style strength in a portable device. An ambient RGB light window and physical controls offer improved usability and aesthetics, and compatibility with the FiiO Control app allows for further customization.
