The FiiO K11 Desktop DAC/Amplifier is a versatile low-profile desktop headphone DAC and amplifier. With multiple inputs — including USB-Type C, optical and coaxial — as well as RCA stereo line-out, the K11 also features a 1.1-inch VA display which can display information about the audio file being listened to.
Available in either black or silver, featuring both single-ended and balanced headphone connections, the K11 is powered by a CS43198 DAC chip and features full support for 32-bit/384kHz and native DSD256 Hi-Res audio files. Despite its relatively small footprint — just 147 x 133 x 32.3 mm — FiiO has engineered the compact K11 to deliver a power output of up to 1400mW. The Fiio K11 will be available from October, priced at $129.
On the K11 are USB, optical, and coaxial inputs as well as 4.4mm, 6.35mm, RCA line-out, and coaxial outputs. Having more inputs and outputs than other typical entry-level amps means the K11 is more than capable of meeting your needs of putting together a capable audio setup; under a 32Ω load, the max undistorted output power under balanced output goes up to 1400mW, allowing it to easily drive many kinds of earphones and headphones.
Moreover, within the K11 lies a specially designed audio circuit designed for great sound quality. This is backed by more than 16 low-noise LDOs for precise voltage stabilization and powered by an external 12V switching power supply.
The K11 has 3 separate gain levels, each gain level having its own volume curve. 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.
In addition, its use 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.
