From the portable desktop-level unit M17, the portable desktop-grade DAC and amp Q7, to the more portable yet desktop-capable M15S, audiophiles’ warm reactions to these models prove many love desktop-level audio gear. After being successfully applied to the three high-end models, the desktop mode will now evolve and be applied to audio dongles.
The FiiO KA13 mini desktop amp features a desktop mode to fully unleash its performance. Let us show you what dongles can do, reaching the incredible heights of desktop-level gear.
With two high-performance yet highly efficient CS43131 DAC chips and two low-noise SGM8262 op-amps, this truly “dual-core” golden combo brings excellent performance. Rediscover your music collection again full of newly discovered details with the KA13.
The KA13 features a desktop mode, which the engraved lightning bolt logo hints at. In desktop mode, balanced output power goes up to 550mW, allowing the KA13 to drive both low and high-impedance headphones with excellent dynamics and detail.
With support for 32bit/384kHz PCM and DSD256, the KA13 despite its tiny size is capable of highly-detailed sound. Hear the details and get a better look into your music.
The KA13 not only manages to fit a 3.5mm single-ended headphone out, it also manages to pack a 4.4mm balanced headphone out. FiiO engineers repeatedly adjusted the design of the KA13 and finally managed to fit two headphone outputs in the compact dongle, marking true progress in packaging capabilities.
*3.5mm interface supports SPDIF output. After turning on SPDIF output through the FiiO Control app, you can convert USB audio signals to coaxial SPDIF signals to connect to external DACs in other audio setups.
The KA13 features a detachable cable design. When combined with the included Type-C and Lightning adapter cables, you can listen with various systems * without having to immediately purchase another cable.
*Compatible with Android, iOS, Windows, Mac.
The RGB ambient light window not only looks good, but also lets you quickly know the sampling frequency of your audio – letting you feel the charm of a device “Born For Music.”
*RGB ambient light window can be turned off through the FiiO Control app on Android devices.
The KA13 supports being controlled with the FiiO Control app. With the app, you can set the RGB lights, SPDIF output, audio filters, etc. for a more convenient experience.
*FiiO Control app’s control over KA13 only supported on Android devices.
The front of the CNC metal body features unique lines, while the rear contains exquisite texture, for an aggressive yet futuristic look. The KA13 is also soft to the touch, for greater comfort every time you use it.
*KA13’s front-panel glass features an anti-scratch film.
Midnight Black : Pure, calm elegance.
