FiiO KA13: an entry-level portable USB DAC amp with dual CS43131 chips and both 3.5mm and 4.4mm balanced outputs. Flip its Desktop Mode switch and FiiO rates the balanced jack at 550 mW per channel into 32Ω (260 mW with it off), enough for collections that mix sensitive IEMs with harder-to-drive headphones.
Who the FiiO KA13 is for
Mixed IEM and headphone collections: Desktop Mode lifts the balanced output from 260 mW to 550 mW per channel at 32Ω (78 mW at 300Ω), at the cost of more battery draw from the phone.
A first balanced setup: Both a 3.5mm single-ended and a 4.4mm balanced jack are built in, so trying a balanced IEM cable doesn't mean buying another dongle.
iPhone, Android and laptop users: FiiO includes USB-C, Lightning and USB-A cables in the box and lists Android, iOS, Windows and Mac compatibility.
Feeding another DAC: The 3.5mm jack can switch to coaxial S/PDIF output in the FiiO Control app on Android.
Skip it if: you want an on-device screen or parametric EQ; an RGB light stands in for a display, there's no onboard PEQ, and its app settings (filters, light, S/PDIF) are Android-only.

FiiO KA13 vs similar options
vs FiiO KA17: Steps up to dual ES9069Q DACs, a 0.91-inch OLED, 10-band PEQ and up to 650 mW @32Ω, but costs more and weighs 33.5 g; pick the KA13 if you can live without a screen.
vs SMSL D10: Same dual CS43131 chips and both jacks in a cheaper 17.5 g stick rated 500 mW @32Ω; the KA13 earns its place with a 550 mW Desktop Mode and coaxial S/PDIF output.
