Clear and detailed sound upgrade
I upgraded to the FiiO KA3 from a basic USB DAC and the difference is night and day. The sound is much clearer and more detailed, especially in the midrange and highs. It's small enough to take with me on trips and works seamlessly with my laptop.

Great sound but missing volume control
The audio quality is fantastic for the price, and the balanced output is a nice touch. My only gripe is the lack of a volume knob on the device itself, so I have to rely on my source or headphone amp volume controls.
