FiiO K11 Desktop DAC & Headphone Amplifier

K11 will feature lots of connectors, large power output, and a slim build. The beautiful screen is a display of its prowess as your desktop HiFi companion.

Variety inputs and outputs

USB, Optical and coaxial inputs, 4.4mm, 6.35mm, RCA line-out, and coaxial outputs.

The K11 used in USB DAC mode does not require a driver on Windows 10 and above systems, and can also be used with video game consoles such as the PS5 and the Switch. Simply plug and play for worry-free usage whether you are enjoying music or being immersed in games.

3 gain levels 3 volume curves

K11 has 3 separate gain levels, each gain level have its own volume curves. This allows the K11 to give you a better listening experience with various types of headphones, whether you are using sensitive earphones or harder to drive over-ear headphones.

Beautiful screen Full of Clarity

A custom, high-contrast and durable LCD screen allows you to easily see the sampling rate, volume, gain, or output mode with just a glance.

The slim aluminium alloy body allows you to easily place the K11 anywhere. Thanks to the silicone anti-slip pad, K11 rests stably and firmly on your table too.
