Portable DAC and Headphone Amplifier


Enjoy high-fidelity audio anywhere with the FiiO KA17, which takes the portable USB dongle DAC to a new level. A dual-channel flagship ESS ES9069Q DAC brings digital prowess in, combined for the very first time with powerful THX AAA amplification in a dongle-sized unit from FiiO.
The KA17 is also equipped with an innovative Desktop Mode. When there is sufficient USB power, or the independent power port is connected to a power adapter like your phone charger, Desktop Mode kicks things up a notch, fully unleashing the output power of the device, with performance that rivals many comparably-priced desktop units.
Purchases from Bay Bloor Radio include a 1-Year Warranty from FiiO Canada, with local repair/replacement without the need for international shipping.

Dual DACs
The KA17 employs two of the new ESS ES9069Q flagship DACs, powered by fourth-generation 32-bit HyperStream module technology. These chips feature even higher performance, lower power consumption, and less digital noise than previous generations for an absolutely pristine and pure audio background.
Handling USB duties in the KA17 is the 16-core XMOS XU316, rarely found in audio dongles. This chip features lower latency, more stable signal transmission, and better compatibility than typically used USB control chip. And with its dual crystal oscillators, the KA17 is more than capable of handling various digital audio sources with various sampling rates: up to 768kHz/32bit, native DSD512 decoding, and MQA full decoding.
Parametric EQ
The XMOS XU316 chip also allowed FiiO engineers to develop a highly precise adjustable parametric equalizer mode, with 10 customizable frequency bands. FiiO’s self-developed PEQ algorithm and interface allow you to fine-tune the frequency, gain, and bandwidth of each PEQ band, letting you dial in the sound exactly the way you want it. Note: Android device with FiiO Control app is required to adjust EQ; iOS is not supported due to Apple limitations for communication over USB. PEQ adjustment is supported in formats up to PCM 192kHz/24bit, and is currently not supported in UAC1.0 mode.
THX Amplification
It’s a first for this form factor. After being well-received in FiiO’s desktop units and portable music players, the amplification technology has been miniaturized to its smallest size yet in KA17. Inside this dongle DAC are THX AAA 78+ headphone amplifiers, with 8 op-amps working in parallel in a 4-channel fully balanced configuration, allowing for not only greater power output but also more detailed and realistic sound.
THX Achromatic Audio Amplifier (THX AAA™) ensures a no-compromise headphone audio experience by delivering the world’s highest fidelity audio with infinitesimally low levels of noise, distortion and power consumption. Patented feed-forward error correction topology creates realistic, fatigue-free listening by reducing harmonic, intermodulation, and crossover distortion.

Desktop Mode

The KA17 features two USB Type-C ports. One is the typical port used to connect to audio source devices such as phones, tablets and computers. But the new orange port on the side is designed for use with an external power supply. When an external power supply is connected to this port, the KA17 can achieve higher power output and better performance without consuming the battery of your phone or other connected device.
This special Desktop Mode is activated using the dedicated “D.Mode” switch on the side of KA17. Once enabled, the KA17 will automatically adjust the DAC, amplifier power supply, and amplifier power output to fully unleash their potential with greater power output that rivals some larger desktop-sized units — particularly when using the 4.4mm balanced output.
Digital and analog, multistage and separate
FiiO engineers were cleverly able to adapt their audio circuit designs from mid to high-end digital audio players to the compact KA17. With its high-precision conversion of digital audio signals — thanks to the dual crystal oscillator clocks and high-performance DAC — plus a robust analogue section consisting of LPF voltage amplification, BUF current expansion, and headphone amps working together in parallel, the KA17 reproduces the detail and dynamics in your music just as well as a serious digital audio player.
The digital and analogue portions of the audio circuit lie on totally separate circuit boards in the KA17, each board equipped with a shielding cover for total isolation. This ensures that the digital and analogue portions of the audio circuit do not interfere with each other, enabling accurate processing of audio signals.
Power supply
Inside the KA17 is a 3-stage 3-main rails power supply design. The three main stages of the power supply consist of first-stage filtering + overvoltage protection, second-stage DC-DC boost conversion, and third-stage LDO voltage stabilization. This filtering of electricity applies to each of the three main power supply rails, one each for the digital, digital-to-analogue conversion, and analogue signal parts of the audio circuit. To top it all off, the power supply circuit is divided into ten smaller rails. The power supply found in the KA17 features many of the same principles as those found in desktop headphone amplifiers, ensuring a robust foundation for the KA17’s excellent sound.
Built into the KA17 are temperature and DC output monitoring systems that ensure both the unit itself and connected headphones won’t be damaged under abnormal conditions. You can also set a maximum volume level to prevent accidental hearing damage to your ears from excessively loud audio
FiiO Control app
Unlock a range of functionality by connecting to the FiiO Control app for Android, including the parametric equalizer. FiiO has also included a UAC1.0 Driver-free mode, which allows you to plug and enjoy your gaming sessions with consoles that don’t support the typical UAC2.0 connection.
One simple screen
Within its aluminum alloy chassis, the KA17 employs a 0.91-inch dot matrix display that can indicate different functions intuitively. The physical buttons easily allows you to customize various settings such as screen orientation, filters, and display sleep timer.
Leatherette case
A matching leather case that protects your KA17 with style, and it’s included in the box.
