FIIO K17

FIIO K17

The New Generation Desktop DAC & Headphone Amplifier

The FIIO K17 is more than just the successor to the K9 Pro-it's a bold step forward in desktop audio. With a blend of retro elegance and advanced technology, the K17 offers a powerful and sophisticated design packed with features. It sets a new standard for high-quality DAC and headphone amplifiers.

High Quality DSP & Advanced Clock Technology

At the heart of the K17 is the M21586Q DSP chip, which performs 64-bit floating-point operations with double precision at an impressive clock speed of 360 MHz. This is complemented by the powerful ES9821Q ADC and a custom-built femtosecond crystal oscillator with ultra-low phase noise. Together, they provide support for a 31-band lossless PEQ in all modes-without loss of signal integrity.

Flagship DAC architecture.

The K17 features AKM's top-of-the-line DAC configuration: the AK4191 combined with two AK4499EX chips-one per channel. Thanks to the 8-to-4-channel LPF design, common mode interference is minimized, leading to better channel separation and dynamics. Fully separated digital and analog sections, along with AKM's latest "DWA ROUTING" technology, provide quieter backgrounds and higher resolution.

Fully Customizable PEQ

Advanced PEQ allows users to tune the sound in detail. Support for PCM signals from 44.1kHz to 96kHz, an adjustable gain range from +12dB to -24dB and Q values from 0.4 to 128 offer comprehensive control. Settings can be easily saved, shared, imported and exported-ideal for simulating or correcting frequency responses from different headphones.

New Discrete Amplifier Architecture

For the first time in a desktop model, FIIO uses a discrete amplifier circuit with an OP + transistor current gain design. With ON Semiconductor MJE243/253 transistors, this amplifier delivers high current with low output impedance, good for up to 4000mW + 4000mW in balanced mode-nearly double that of the K9 Pro ESS. The result: effortless driving of all kinds of headphones and IEMs, with natural, smooth and richly detailed sound.
