FiiO K11 DAC and Headphone Amplifier for Home Audio or PC
Overview
The FiiO K11 is a compact desktop DAC and headphone amplifier with 6.35mm and 4.4mm balanced headphone outputs and an RCA line output. It replaces a computer's or console's built-in audio with cleaner sound and enough power for most headphones, in a slim box that sits easily on a desk.
A Cirrus Logic CS43198 DAC handles PCM up to 384kHz/32-bit and native DSD256 over USB-C, plus 192kHz/24-bit over coaxial and 96kHz/24-bit over optical. Two SGM8262 amplifier chips in a truly balanced circuit deliver up to 1400mW per channel into 32 ohms from the 4.4mm output and 520mW per channel from the 6.35mm output, with an SNR of at least 123dB. More than 16 low-noise LDO regulators and an external 12V power supply keep the power clean, and three gain levels with three volume curves let you match anything from IEMs to full-size headphones.
A high-contrast custom LCD shows volume, sample rate and settings, and the RGB logo light's colour, brightness and pattern are adjustable. The multi-function knob handles volume and menus, and a double press switches between headphone output and line output, each remembering its own volume. The K11 works driver-free with Windows 10 and later, as well as the PS5 and Switch, and also has a coaxial digital output in USB mode.
Simcoe Audio Video Insight
The K11 is an easy way to give a computer or console a proper headphone amp without a big stack. Use the 4.4mm output for the most power, and low gain for sensitive IEMs. If you also run powered speakers, connect them to the RCA line out and double-press the knob to switch between headphones and speakers; each mode keeps its own volume. On Windows, it works without a driver, but installing FiiO's driver unlocks higher sample rates.

Buyer's Guide
Who It's For
- The PC Listener: Wants better sound than onboard audio.
- The Console Gamer: Wants a proper headphone amp for PS5 or Switch.
- The Desk Speaker User: Wants a line out for powered speakers too.
How It Compares
The K11 uses a Cirrus Logic CS43198 chip DAC. FiiO's K11 R2R uses the same chassis with FiiO's own R2R resistor-ladder DAC, for listeners who want to try that style of conversion.
