Fiio KA11 review: This $29 USB DAC is the best way to upgrade your phone audio

The KA11 has all the power you need to drive just about any IEM, and it produces a great sound.

(Image credit: Harish Jonnalagadda / Android Central)The cable connecting the USB port to the DAC is made out of a high-purity oxygen-free palladium-plated copper wire, and it is sheathed in a silicone braid, giving it added durability. It uses a Cirrus Logic CS43131 DAC chip along with an SG-Micro SGM8262 amp and Savitech SA9312L USB controller, and the USB-C version works seamlessly with Windows and macOS machines in addition to Android and the latest iPhones.
