KA15 - Portable USB DAC & Headphone Amplifier

The FiiO KA15 is a compact yet powerful USB DAC and headphone amplifier designed for audiophiles who want exceptional sound quality on the go or at their desktop. Equipped with dual Cirrus Logic CS43198 DAC chips and dual SGM8262 op-amps, it supports high-resolution audio playback up to PCM 768 kHz/32-bit and native DSD256 decoding. The device features a unique retro-inspired design with a 0.96-inch true-color LCD display that shows sample rate, voltage and current monitoring, and menu information. It offers both single-ended (3.5 mm) and balanced (4.4 mm) headphone outputs, with desktop mode delivering up to 560 mW per channel balanced power — plenty for driving demanding headphones and IEMs. A built-in 10-band parametric EQ and app control give you customizable sound shaping, and intelligent power management adjusts consumption dynamically based on playback status
