FiiO K17 Desktop DAC and Headphone Amplifier

FiiO K17 is equipped with USB/optical/coaxial inputs, 4.4mm/6.35mm/RCA line out/coaxial outputs, and a balanced maximum undistorted sustained output power of up to 4000mW per channel at 32Ω, which can be used for all types of earbuds and headphones.

M21586Q DSP Chip

The K17 features an M21586Q DSP chip which is capable of double- precision 64-bit floating-point calculations, and runs at a high 360MHz clock frequency. This chip is complemented by a high-performance ES9821Q ADC aswell as a specially customized ultra-low phase noise femtosecond crystal oscillator. These three components allow the user, in all modes, to utilize the 31-band high-precision lossless PEQ, The PEQ is designed to ensure the audio signal is still of high fidelity even after being processed.

3.93-inch Color Screen

With a larger color screen, combined with a custom Android 12 build that features a custom portrait display system, the display is clear and easy toread. Interacting with the device directly is intuitive, so that it is easy to handle various operations right out of the box.

Discrete Cass AB Transistor Current Amplification Headphone Amplifier

The K17 is a carefully crafted fully discrete amplifier circuit for headphones. This discrete circuit is of an OP+ transistor current amplification design, equipped with the classic pair of ON Semiconductor MJE243/253 transistors. lt is capable of producing high current with low output impedance. The result is up to 4000mW+4000mW output power inbalanced mode, allows it to easily drive various kinds of headphones and lEMs and to produce smooth, pleasant, and natural sound.

AKM flagship DAC AK4191+AK4499EX*2

The K17 has flagship AKM DAC chipcombination – AK4191+AK4499EX*2. TWO AK4499EX chips handle each channel. The 8-channel to 4-channel LPF design reduces common mode interference, resulting in better channel separation and dynamics. lt also features a newly designed architecture with fully separated digital/analog portions, which also incorporates the newly developed “DWAROUTING” technology for an even cleaner audio background and improved resolution.
