FiiO KA17
Universal Summary
The KA17 is FiiO's $149.99 flagship dongle: dual ESS DACs feeding a THX AAA 78+ stage that scales from 300mW balanced on phone power to 650mW with an external supply in Desktop Mode. Approved reviews agree its pitch is unmatched drivability-per-dollar: Headfonics rates it one of the favorite dongles of its price segment for driving both IEMs and full-size headphones while staging well, and MajorHiFi's measurements confirm the power story. The recurring caveats are practical: it is large and power-hungry for a phone-fed dongle, and its clean, balanced tuning is more capable than characterful.
