FiiO K11 - Black - Silver

Description

A Compact and Powerful Desktop DAC/Amp
The FiiO K11 emerges as the new entry-level desktop DAC/amp, designed to meet the evolving needs of HiFi users. With a powerful 1400mW balanced output, a wide range of inputs and outputs, a custom LCD screen, and a slim aluminum design, the K11 is built to be the perfect everyday HiFi companion that blends elegance and performance.

Dedicated Audio Circuit and Power Supply
Inside its slim profile, the K11 houses a specially designed audio circuit optimized for stability and high-quality sound. Backed by more than 16 low-noise LDO regulators and powered by an external 12V/2A supply, the system ensures clean, precise voltage regulation throughout the audio chain. This advanced design results in consistently pure, robust, and distortion-free audio reproduction.

High Power Output
Delivering up to 1400mW+1400mW at 32Ω (balanced), the K11 drives most HiFi headphones and IEMs with ease. Whether for power-hungry high-impedance models or more sensitive earphones, the K11 unlocks their full potential with rich, controlled performance.

Three Gain Levels and Volume Curves
The K11 includes 3 different gain levels, each with its own unique volume curve. This ensures a better listening experience across a wide variety of headphones—from ultra-sensitive IEMs to full-sized, harder-to-drive over-ear models—while maintaining a comfortable and precise control of loudness.

Custom LCD Screen and RGB Logo Lighting
The high-contrast, durable LCD display provides clear information on sample rate, volume, gain, and output mode at a glance. Meanwhile, the illuminated FIIO logo includes adjustable RGB lighting for brightness, color, and effect style—providing both functional feedback and a stylish accent for any desktop.

Multiple Inputs and Outputs
The K11 offers extensive connectivity options:

• Inputs: USB-C, optical, coaxial
• Outputs: 4.4mm balanced, 6.35mm single-ended, RCA line-out, coaxial

This flexibility ensures the K11 can seamlessly integrate with nearly any audio setup, whether for headphones, DAC integration, or speaker connection.

Multi-Function Knob and Easy Compatibility
The K11’s central control knob acts as a multi-function interface, enabling precise 112-step volume adjustment, powering the device on/off, menu navigation, and easy mode switching. Users can quickly toggle between headphone out and line-out modes, with each remembering its last volume setting. The K11 also functions as a driver-free USB DAC for Windows 10 and beyond, and is fully compatible with PS5 and Switch—making it simple plug-and-play for music, gaming, or movies.

Premium Slim Design
Crafted from CNC-machined aluminum alloy, the K11 combines durability with sophistication. With a slim build (147 × 133 × 32.3 mm) and a silicone anti-slip pad for stability, it integrates elegantly into any desktop space. Available in three finishes—Obsidian Black, Midnight Silver, and Titanium—it merges style with high-end performance.
