FiiO KA13 Portable Headphone DAC/Amp
Overview
The FiiO KA13 is a portable USB DAC and headphone amplifier with two Cirrus Logic CS43131 DAC chips and two SGM8262 op-amps, plus a desktop mode that raises balanced output to 550mW per channel. It's for listeners who want one small dongle that handles IEMs on the go from a phone and can also drive full-size headphones properly at a laptop or computer.
A switch on the body turns desktop mode on and off. With it on, the 4.4mm balanced output delivers up to 550mW per channel into 32 ohms and the 3.5mm output 170mW; with it off, power drops to 260mW balanced and 50mW single-ended into 32 ohms. It plays up to 384kHz/32-bit PCM and DSD256 and is Hi-Res Audio certified, with SNR of 123dB single-ended and 122dB balanced.
The 3.5mm jack can also work as a coaxial SPDIF output to an external DAC once you turn it on in the FiiO Control app, which on Android also sets filters and the RGB light. The light window shows light blue for 48kHz and below, yellow above 48kHz and green for DSD. The cable is detachable, with USB-C to USB-C, USB-C to Lightning and USB-C to USB-A cables included, and a button handles volume and track skipping. The CNC metal body comes in Midnight Black or Dawn Silver.
Simcoe Audio Video Insight
Leave desktop mode off for IEMs on a phone, since sensitive in-ears don't need the extra power. Turn it on when you sit down with full-size headphones, especially on the 4.4mm balanced output, where power more than doubles. If you have a separate DAC at home, the SPDIF output lets the KA13 work as a USB-to-coaxial converter, but you'll need an Android device with the FiiO Control app to switch it on.

Buyer's Guide
Who It's For

- The Multi-Device Listener: Uses Android, iPhone and a laptop.
- The Balanced-Cable User: Wants a 4.4mm output in a dongle.
How It Compares
Compared with the FiiO KA11, the KA13 adds a 4.4mm balanced output, desktop mode and a detachable cable with USB-C, Lightning and USB-A cables included. The KA11 is smaller and lighter, with a 3.5mm output and a fixed cable.
