The FiiO K series is the company's popular line of desktop DAC/amps catering to the mid-range market. However, the newly released K11 model is now available in Our Store, targeting entry-level users who are looking for an affordable solution to upgrade the sound quality of their computer speakers (including active speakers, studio monitors, and headphones).


The FiiO K11 is a portable DAC (Digital-to-Analog Converter) and amp (amplifier) designed to enhance the sound quality when listening to music from mobile devices, computers, or other audio sources. Below are some of the key features of the FiiO K11:

  • Unleash the full sonic potential of your high-end headphones with the FIIO K11 Desktop 1400W Power Balanced Headphone DAC & Amplifier.

    • Balanced 4.4mm output delivers a massive 1400mW of power

    • Single-ended 6.3mm output provides 520mW for more versatility

    • 3 gain modes for optimal performance with any headphone

    • Advanced DAC and amplifier circuitry for exceptional audio fidelity

  • The FIIO K11 is the desktop audio powerhouse your high-impedance headphones have been waiting for. With its beefy 1400mW balanced output, it effortlessly drives even the most demanding cans like the HiFiMan Ananda Nano and Sennheiser HD 600 series.

  • Serious audiophiles and music enthusiasts will appreciate the K11's uncompromising sound quality and flexible connectivity. Whether you prefer a balanced or single-ended connection, the K11 has you covered with its dual outputs and selectable gain modes. Elevate your listening experience and hear your music collection like never before with the FIIO K11.

  • The FiiO K11 functions as a DAC/Preamp for active speakers like the Genelec G One or the FiiO SP3 via the RCA single-ended output at the back. Note that the K11 has two modes: PO (Phone Out) and LO (Line Out). Only one of these modes can be used at a time; both cannot be active simultaneously.

  • The K11 supports UAC1 and UAC2 (USB Audio Class), making it compatible with devices such as the Nintendo Switch, Sony PlayStation, computers, and laptops. It also features both Optical input and Coaxial In/Out.

  • Using the K11 as a DAC for gaming consoles offers several advantages. I currently have a Devialet Dione for watching movies and gaming, but with a young child at home, it’s impossible to turn on the speakers at night. And honestly, who wants to play games without sound? That just wouldn't be the same! Some might suggest simply plugging headphones into the 3.5mm jack on the PS5 controller, but honestly, if you haven’t tried it yet, it sounds pretty bad 😔. Moreover, the output power of the 3.5mm jack on the PS5 controller is very weak, and even with headphones like the HD 300 Pro, it can barely drive them, let alone handle a pair of planar magnetic headphones. That's where the K11 comes in as a great solution. If you have a PS4, you can connect it to the K11 through the Optical input.


  • The K11 features a CS43198 DAC chip, enabling it to decode PCM 24-bit/192kHz and DSD256 audio. It connects to computers, PS5, and Nintendo Switch via a USB-C interface. The device runs on 12V DC power, with the potential for future power supply upgrades to enhance sound quality. According to the manufacturer, the K11 incorporates a high-precision linear voltage regulator (LDO) power supply and filtering system to cleanly power the decoding and amplification circuits.



  • Prepare to be captivated by the FIIO K11 - a desktop DAC and amplifier that redefines the listening experience. Engineered to deliver exceptional sound quality, the K11 is the ultimate choice for music enthusiasts and audiophiles alike.

    • 1400W of balanced power for rich, expansive sound• Precise, detailed midrange response without overpowering bass• Sleek, modern design that complements any home setup

  • The FIIO K11 represents a new benchmark in audio technology. Its balanced output ensures exceptional clarity, allowing you to immerse yourself in the nuances of your favorite tracks. With a focus on realism over artificial enhancement, this amplifier brings you closer to the artist's original vision.

  • Whether you're seeking to elevate your daily listening or take your audiophile experience to new heights, the FIIO K11 is the perfect solution. Unlock the full potential of your music and discover a new level of audio bliss that will captivate your senses.
