I’ve spent the last several months reviewing a small mountain of gear — pocket dongles, budget desktop boxes, flagship ladder DACs, planars, wireless flagships — and one uncomfortable question has been circling the whole time. If a Bluetooth device the size of a matchbook can drive my planars properly, what exactly is the desk full of separates for?
Shanling has been building towards this since the UP2: a Bluetooth dongle that stops apologising for being wireless. The UP5 was the previous flagship; the UP6 replaces it with dual ESS DACs, a proper colour screen and enough balanced power that “just a dongle” stops being an accurate description. This is the segment FiiO’s BTR17 has been quietly redefining, and Shanling clearly noticed.
The hip-dac has always been the fun one — that gaudy copper-and-black shell, the glowing volume knob, the sense that iFi didn’t take itself too seriously even while the electronics inside were dead earnest. Three generations in, the joke’s worn off and what’s left is a genuinely accomplished USB DAC/amp that happens to still look like nothing else on your desk. It’s not chasing the BTR17 or the Mojo 2 on outright spec-sheet bragging rights; it’s chasing “you’ll actually use this every day,” and it mostly wins.
Every category needs a device everyone else gets measured against, and in pocket Bluetooth DAC/amps that’s been the Qudelix-5K since 2020. Six years is a geological age in dongle years, yet it’s still the first name that comes up when someone asks for portable parametric EQ done properly. That kind of staying power isn’t an accident.
FiiO’s dongle line has quietly turned into a technology testbed, and the KA17 is where the ambition goes furthest. No Bluetooth radio, no screen gimmicks for their own sake — just two flagship DAC chips, a dedicated power port, and a Desktop Mode that genuinely means it. Having just spent weeks with the BTR17, its wireless sibling from the same generation, the KA17 is the wired, no-compromise answer to the same question: how much desktop-grade amplification can you cram into something that lives on a keyring?
FiiO has spent a decade quietly perfecting the pocket DAC/amp, and the BTR17 is the point where the formula stops feeling like a compromise. This is a Bluetooth dongle that, given a second USB cable, will drive a pair of planars that used to demand a desk full of separates. The BTR7 was good; this is the one that made me wonder what my desktop stack is actually for.
