  • Cirrus Logic CS43198 DAC;
  • supports 32-bit/384kHz and DSD256;
  • stylish display;
  • 1400mW output power at 4.4mm output and 512mW at 6.35mm;
  • customizable logo backlight;
  • 3 levels of gain;

For many years, Fiio has released models like K5 Pro, K7, K9, and amplifiers in the K9 Pro series at various prices. The K series amplifiers sell well worldwide, meeting users' evolving needs for HiFi on desktop computers. Extensive research and progress have led the company to a new understanding of entry-level amplifiers.

Multiple Inputs and Outputs

The K11 features USB, optical, and coaxial inputs, as well as 4.4mm, 6.35mm, RCA, and coaxial outputs. With more inputs and outputs than typical entry-level amplifiers, the K11 is more than capable of meeting your needs for a high-quality audio system. USB connection to phones for decoding does not drain the phone's battery, and the coaxial input and output share the same physical connector.

High Output Power

With a 32-ohm load, the K11 can deliver 1400mW in balanced mode, easily driving many Hi-Fi headphones and headsets to unleash their full potential.

3 Gain Levels

The K11 offers 3 separate gain levels, each with its own volume curve. This allows the device to provide you with the best listening experience with various types of headphones, whether you use sensitive headphones or in-ear monitors with more demanding requirements.

Specially Designed Audio Circuit and Power Source

Inside the slim body of the K11 lies a specially designed audio circuit that ensures excellent sound quality. With more than 16 low-noise LDO circuits for precise voltage stabilization, it uses an external 12V power supply. This leads to cleaner and more reliable power for electronic components, ensuring stable high-quality sound at all times.

Slim on one side, stable on the other

The aluminum alloy slim body allows you to easily place the K11 anywhere, complementing the rest of your desk. With a silicone anti-slip pad, the K11 also sits sturdily and securely on your desk.

Beautiful and Bright Display

The customizable, high-contrast, and durable display with a VA matrix allows you to easily see the sampling frequency, volume, gain coefficient, or output mode at a glance.

Multifunctional Knob

In the minimalist design of the K11, the volume knob serves as a key control source. The multifunctional volume adjustment knob is used to power the device on and off, navigate menus, adjust volume, and other functions. The knob is designed so that you can quickly perform various complex actions by simply pressing and turning it. You can also quickly switch between LO/PO gain modes by double-clicking the knob, making it easier to connect to different audio systems. The LO/PO modes remember the last volume set in each mode independently, eliminating the need to readjust volume when switching between modes.

Driverless Mode

When used as a USB DAC, the K11 does not require driver installation on Windows 10 and above systems and can also be used with gaming consoles like Sony PS5 and Switch. Just plug in and play for hassle-free use, whether you're enjoying music or immersed in games.

Package includes:

  • DAC;
  • power supply;
  • USB-A to USB-C cable;

Power output

This is the useful power developed by the amplifier in the load resistance. Amplifiers are usually characterized by the highest power that can be obtained at the output, provided that the distortion does not exceed the specified permissible value. This power is called the output power of the amplifier.
