The FiiO KA17 is a portable USB-C DAC/amp with dual ESS ES9069Q chips and THX AAA 78+ amplification. With Desktop Mode on and enough USB power, FiiO rates its 4.4mm balanced output at 650 mW per channel into 32Ω, so one 33.5 g dongle can serve IEMs, many planars and 300Ω headphones from a phone or at a desk.
Who the FiiO KA17 is for
Planar and 300Ω headphone owners: Desktop Mode lifts the 4.4mm jack to 650 mW per channel at 32Ω and 90 mW at 300Ω, and FiiO rates that output for 8–300Ω loads.
One DAC for phone and desk: It runs off a phone's USB-C port on the go; at a desk, a charger in the orange USB-C power input lets it reach full output without draining the phone.
EQ tweakers: Its 10-band PEQ is set in the FiiO Control app on Android or from a computer, and the KA17 stores the result so your tuning travels with it.
Mixed cable collections: A 4.4mm balanced jack sits next to a 3.5mm jack that doubles as a coaxial digital output, with a 0.91-inch OLED showing what is set.
Skip it if: you only drive sensitive IEMs from a phone and will never use the extra power, or you need to adjust it from an iPhone, since FiiO says iOS devices can't change KA17 settings through its app.

FiiO KA17 vs similar options
vs FiiO BTR17: Adds Bluetooth 5.4 (LDAC, aptX Lossless) and a battery to the same dual ES9069Q and THX AAA 78+ design; pick the KA17 if you only listen wired and want the lighter 33.5 g body.
vs Shanling UA4: Weighs 20.8 g to the KA17's 33.5 g and uses one ES9069Q; choose the UA4 for IEMs from a phone, the KA17 when headphones need up to 650 mW @32Ω.
vs FiiO KA13: Cheaper, with dual CS43131 and up to 550 mW @32Ω balanced in Desktop Mode but no screen; pick the KA17 for its OLED display, 10-band PEQ and 650 mW ceiling.
USB-C data + USB-C power in; 3.5 mm (PO/coax) + 4.4 mm balanced out
