FIIO KA15 DAC and Headphone Amplifier

The desktop mode really delivers on the power — 560mW per channel drives my high-impedance headphones effortlessly. I love watching the real-time current and voltage monitoring on the screen while adjusting the 10-band PEQ.

The 10-band PEQ is incredibly precise and lets me fine-tune my headphones exactly how I like them. I was surprised by how much cleaner everything sounds even at lower volumes.

Desktop mode on this little thing drives my planar headphones way louder than I expected, and there's zero distortion even at higher volumes. The live current and voltage readout is a nerdy touch I didn't know I wanted until I caught myself watching it during a whole album.
