Convenient DAP Docking

With three different gain settings to power a variety of headphones and a docking base compatible with the X-series line of FiiO digital audio players, the K5 is one of the most versatile headphone amps in its category. Utilizing TI’s TPA6120A2 current feedback headphone driver, it’s able to lower its output impedience to a transparent <1 ohm and increase its output power up to 1.5 watts at 32 ohms. On the back, you’ll find a balanced line output, RCA input, a secondary dock input, and a USB port. For a more extensive review, read more here.

Note: This drop is limited to 27 units.
