The FiiO K17 is a full- balanced desktop DAC and headphone amplifier featuring a discrete Class AB circuit, dual AKM flagship DACs, and a 4000mW+4000mW output built for audiophiles who demand clean power, low noise, and versatile connectivity. Its robust build, intuitive touchscreen, and multiple connectivity options make it an incredibly versatile hub for your audio system. Whether you're driving high-impedance headphones, fine-tuning your sound with a 31-band PEQ, or streaming lossless audio over Gigabit Ethernet, the K17 handles it all with precision and retro personality.
A DAC designed for high fidelity
An AKM flagship DAC chipset AK4191+AK4499EX decodes your digital files. Each channel is handled by a dedicated AK4499EX, improving channel separation and dynamic range. The design also incorporates AKM's "DWA ROUTING" technology, ensuring a clean background and detailed sound reproduction.
Discrete Class AB amplification
The K17 features a fully-discrete Class AB transistor current amplification headphone amplifier. Using ON Semiconductor MJE243/253 transistors, this design delivers high current with low output impedance. The result is 4000mW+4000mW of balanced output, enabling it to drive a wide range of headphones.
Analog and digital - separate power supplies for cleaner audio
By keeping the power supplies for the digital and analog circuits separate, the K17 reduces interference and crosstalk, giving you purer audio signal, free from unwanted noise or distortion.
Multi-stage analog power supply
The K17's analog circuitry benefits from a multi-stage power supply, with dedicated power control circuits for different stages of the signal path. Secondary voltage regulation with low-noise TPA7A47/7A33 LDO regulators ensures steady, clean power delivery for uncompromised audio performance.
PEQ that doesn't compromise quality
A built-in M21586Q DSP chip enables a 31-band high-precision lossless PEQ. Unlike traditional EQ systems that can degrade audio fidelity, this PEQ preserves signal integrity while allowing you to fine-tune your sound.
Low-noise, high-stability clocking
Three ultra-low phase noise femtosecond crystal oscillators ACCUSILICON AS318-L (45.1584MHz, 49.1520MHz) and AS318-Pro (24.576MHz) ensure precise timing for digital audio conversion. This reduces jitter and maintains signal accuracy across various sample rates.
3.93-inch touchscreen
A large, easy-to-read touchscreen makes navigating the K17's functions straightforward. Combined with an infrared remote, it puts control at your fingertips whether you're fine-tuning settings or switching inputs.
Wired and wireless - your choice
With both Gigabit Ethernet and 2.4G/5G Wi-Fi, the K17 offers stable, high-speed network connectivity. Stream lossless audio without dropouts or interruptions no matter how you prefer to listen.
Physically separated boards reduces interference
The K17's internal design places the power supply, digital, and analog sections on separate circuit boards. This minimizes interference, ensuring accurate signal processing and a cleaner audio output.
Intelligent protection systems
With multiple layers of protection, the K17 ensures reliable operation and long-term durability:
Headphone amp temperature protection
Transformer temperature protection
Output overload protection
Output DC protection
Power input overcurrent protection
