Design and Aesthetics

The FiiO K17 boasts a striking vintage-inspired design, available in silver or black. Its compact size and tasteful aesthetics make it an attractive addition to any desktop setup. The inclusion of a large touchscreen adds a modern touch, contrasting beautifully with the classic design elements.

Conversely, the FiiO K19 adopts a more modern, almost sinister aesthetic, also offered in silver or black. Its design is sleek and minimalist. It can even be positioned vertically for a unique visual appeal.

Both units showcase a distinctive design language, setting them apart from traditional audio gear. However, personal preference will ultimately determine which design resonates more with the individual user.

FiiO K17 Features and Functionality

The FiiO K17's 3.93-inch touchscreen provides intuitive control over various settings and functions. The responsive interface allows for effortless navigation through menus, EQ options, and input selection.

Swipe gestures facilitate easy access to menus and input choices. Users can adjust playback modes, EQ settings (including 10 custom profiles via the FiiO DSP app), volume limits, and balance. Network connection setup is also streamlined via the touchscreen.

Beyond the basic controls, the K17 offers advanced features such as screen brightness adjustment, sleep timer customization, RGB lighting control for volume knobs, and the unique ability to toggle between UAC 1 and UAC 2 modes for broader device compatibility.

FiiO K19 Features and Functionality

The FiiO K19 maintains a similar feature set to the K17 but with some notable additions and omissions. While it lacks the touchscreen interface, it compensates with physical controls and a 12V trigger output, missing on the K17.

A key differentiator is the K19's inclusion of HDMI input and output, supporting 4K 60Hz (though tested at 120Hz). This offers seamless connectivity with gaming consoles and televisions, leveraging ARC for audio return channel.

Despite the lack of network streaming, the K19 retains Bluetooth capabilities, including LDAC and aptX support. The powerful 31-band parametric EQ remains a staple, customizable via the FiiO DSP app (PC and Mac).

Sound Quality and Performance

Both the K17 and K19 deliver exceptional sound quality with a remarkably silent noise floor, even at high volumes. Their clean, detailed audio reproduction is characteristic of high-end DAC/amps.

The K19 exhibits a slightly darker and more centered sound signature, attributed to its THX topology amplification. The K17, employing an AKM system, presents a slightly wider and more lively soundstage.

Subjective differences between the two are minimal, with both delivering exceptional clarity and power. The choice between them largely depends on personal preference and the subtle nuances of each amp's sonic characteristics.

FiiO DSP App and Customization

The FiiO DSP app empowers extensive customization through a powerful 31-band parametric EQ. Users can precisely target specific frequencies and adjust Q factors for granular control over the audio profile.

The app also includes options for dynamic range compression and limiting. The ability to export and import EQ profiles allows for sharing and collaboration among users.

While the extensive control is appreciated, its complexity might overwhelm users unfamiliar with parametric EQ. The app's intuitive design, however, makes the process manageable for most users.

Gaming Performance and Conclusion

For gamers, both the K17 and K19 excel, particularly with the K19's HDMI connectivity and ARC support. The 31-band parametric EQ allows users to create custom profiles optimized for various game genres.

The absence of microphone support is the primary drawback for some gamers. However, their incredible sound quality, clean output power and extensive customization options make them suitable for most gamers.

Ultimately, the choice hinges on individual needs and preferences. The K17's touchscreen and vintage-inspired style appeal to certain users. The K19's added features, like HDMI and 12V trigger output, might sway others. Both are excellent DAC/amps with very minor differences in sound signature.
