Let’s delve into its features, sound quality, and overall value proposition of what you get at the cost of $150.
Disclaimer:
For this review, I received the FiiO KA17 directly from FiiO for a review. While I am grateful for this opportunity and their support, I want to assure you that my opinions and evaluations are based solely on my own critical listening and experience with the product. I strive to remain objective and unbiased in all my reviews, regardless of any collaboration or partnership.
Introduction
The KA17 immediately impresses with its sleek design. The aluminum alloy chassis feels sturdy and premium, while the glass front panel, which acts as a screen, adds a touch of elegance. There are no creaks or loose parts, solidifying the build quality.
The FiiO KA17 doesn’t just occupy the top spot in their USB DAC/amp lineup; it embodies a shift in how audiophiles experience high-fidelity sound. Driven by the rise of smartphone music libraries and the increasing popularity of streaming services, FiiO recognizes the growing demand for on-the-go audiophile solutions. Traditional options like Bluetooth offered convenience, but USB dongles provided a more compact and plug-and-play solution with greater potential for audio prowess.
Building upon the success of previous generations, FiiO leveraged their expertise in DAC and headphone amp technology to develop the KA17 as a true flagship dongle. This wasn’t just about chasing market trends; it was about responding to a growing user base transitioning from basic sound quality expectations to a desire for audio that rivals dedicated portable players.
But FiiO doesn’t stop at pushing boundaries. Recognizing the competition in the high-end dongle market, FiiO strategically positions the KA17 within their existing product line, offering flagship performance at a price point that resonates with audiophiles on a budget. This strategic placement, spanning a range of $30-$150 (making the KA11 the most budget but not a slouch at all), ensures their commitment to catering to diverse needs and usage requirements.
In essence, the KA17 represents the culmination of FiiO’s expertise, market awareness, and commitment to democratizing high-fidelity audio. It’s not just a product; it’s a statement – a declaration that flagship sound doesn’t require a flagship price tag and that convenience and exceptional audio quality can coexist in your pocket.

The device is elegantly displayed, protected by a plastic foil, and accompanied by a matching leather case for added protection. Inside the box, users will find a USB Type-C to USB-C cable, a USB-C to large USB-A adapter, and two silicone plugs for the USB-C ports to prevent dust buildup.

First of its kind
First ever dongle with an independent power supply.
Forget limitations! The KA17 boasts the first-ever independent power supply port in a DAC.

This translates to exceptional power, effortlessly driving even demanding headphones while opening up a whole new world of sonic exploration through “power swapping” for different dynamic responses. While connected to the external power supply, the primary Type C isn’t consuming power but just transferring data.
Powering Performance: Advanced XMOS XU316 Controller
The KA17 leverages the powerful XMOS 16-core XU316 controller, known for its superior processing capabilities and low latency. This advanced chip, chosen and further optimized by FiiO, ensures smoother data handling and exceptional digital audio performance.
Fine-Tune Your Audio Experience: Specialized 10-band Parametric EQ
You can control your sound with the KA17’s versatile 10-band parametric EQ. Unlike basic EQs, it offers deep customization options, allowing you to adjust values precisely to your preferences. Forget complex terminology; the user-friendly graphical interface makes adjusting these parameters intuitive and straightforward. What you see is what you get, ensuring your desired sonic adjustments translate directly to your music.
But the power doesn’t stop there. Built on the foundation of the XMOS processor, this high-fidelity EQ supports high-resolution adjustments at up to 192kHz sampling rates. This means your meticulously crafted EQ settings remain accurate and detailed, preserving the essence of your music without compromise.
Unbound Audio Fidelity: Redefining Portable Performance
The KA17 transcends traditional designs, drawing inspiration from high-end music players. Its meticulous architecture preserves every audio detail, from the DAC to the final output. Dual DACs and a four-channel, fully differential amp work in harmony to deliver exceptional dynamics and channel separation.
But it’s the power that truly sets it apart. Over ten independent power supplies, with a dedicated three-level system for the analog section, ensure pristine power delivery for clean, transparent sound. This combination of innovative design and pure power unlocks a level of audio fidelity rarely seen in a portable device.
Unleashing Flagship Sound: Dual ES9069Q DACs

However, be warned: desktop mode requires an additional USB-C cable for power, adding a slight inconvenience.
App Integration: Convenience with a Caveat

Its core signature leans towards smooth and energetic with a touch of warmth, offering a natural and balanced presentation with impactful bass, detailed mids, and airy highs. Here’s a breakdown of its key characteristics:
Tight and controlled bass, avoiding muddiness. The KA17 delivers impactful kicks and rumbles without overpowering the rest of the frequency range. Whether it’s the thump of electronic music or the low-end growl of a bass guitar, the bass’s presence is satisfying and punchy.
Clear and detailed mids, faithfully reproducing vocals and instruments. Vocals sound natural and engaging, with nuances and emotions conveyed accurately. Instruments like guitars, violins, and flutes have a well-defined presence, allowing each note to shine through.

However, the DC04PRO offers a more compact and lightweight design, making it even more pocket-friendly. Something in the DC04PRO makes me always come back to it, but the KA17 is still the superior one with more features, better quality overall, and much higher versatility.
FiiO KA17 vs. Tanchjim Space:
Choosing between the FiiO KA17 and Tanchjim Space hinges on your priorities. The KA17 reigns supreme with desktop-grade power (650mW) for demanding headphones and boasts a wider feature set like EQ and MQA support, but comes at a higher price and larger size. The Tanchjim Space prioritizes a more neutral and reference sound signature, portability with a compact design, and is more budget-friendly, but sacrifices power (230mW) and features. Consider your needs for power, portability, features, and budget to make the best choice.
conclusions
The FiiO KA17 lives up to its flagship moniker by offering cutting-edge technology, excellent sound quality, impressive power output in a compact and portable form factor, and, not less important, a very fair price for what it offers. While the lack of app control for gain and some more features you would like to quick access rather than start scrolling in the settings on the device itself is a minor inconvenience, the desktop mode, MQA decoding, and thoughtful design features set it apart from the competition. Considering its exceptional value for money, the KA17 becomes a compelling choice for audiophiles on the go seeking flagship-level performance without the flagship price tag. Users wanting desktop-level performance from a portable DAC/AMP with the flexibility for home listening.
