Multi-Input DAC/Amp with 1400mW Output

Introducing the FiiO K11: a compact powerhouse of sound that packs a punch without blowing your budget. Priced at an accessible $129, this Desktop DAC/Amp offers a feature-rich audio solution that promises quality without the high-end price tag. With its balanced output and a robust chassis, the K11 is a testament to the essentials done exceptionally well.

Harmony in connectivity

The K11 prides itself on its plethora of connections. Whether it's USB, optical, or coaxial inputs, or its 4.4mm, 6.35mm, and RCA line-out, the K11 ensures seamless integration into your audio environment. Its clever design allows coaxial input and output to merge into one connector, streamlining your setup without sacrificing functionality.

Power in your palms

With a 1400mW output under its belt, the K11 isn't shy about its capabilities. Even with a 300Ω load, this amp doesn't falter, offering 250mW to drive high-fidelity earphones and headphones with ease, ensuring they reach their full sonic potential.

Tailored listening

Navigating through different audio profiles is effortless with the K11's trio of gain levels and volume curves. Each gain stage has been tuned to match a variety of headphones, ensuring that from the most sensitive IEMs to the most demanding cans, your listening experience remains uncompromised.

A sanctuary of sound

Tucked within the slim frame of the K11 is an audio circuit specifically crafted for clarity. More than 16 low-noise LDOs provide voltage stabilization, while the external power supply maintains a consistent, pure energy flow—resulting in a sound quality that's both pristine and powerful.

A study in elegance

The sleek aluminum alloy body of the K11 complements any desktop setup, while the anti-slip pad ensures it remains anchored during your most intense listening sessions. This balance of aesthetic and stability makes the K11 a staple on any desk.

Visual and tactile delight

The custom VA display on the K11 not only withstands the test of time but also offers at-a-glance information on your music's technical details. Meanwhile, the adjustable RGB lighting on the FiiO logo adds a subtle, customizable flair to your space.

The central command

Simplicity meets functionality with the K11's multi-function knob. This singular control point allows you to power on, navigate menus, adjust volume, and toggle between LO/PO modes with intuitive ease, ensuring a streamlined user experience.

Effortless integration

For those seeking uncomplicated compatibility, the K11's USB DAC mode eliminates the need for drivers on modern systems and is even game-console friendly. It's plug-and-play simplicity at its finest for both music and games.
