The FiiO KA17 is a portable USB headphone amplifier and DAC featuring two ESS ES9069Q converters, one per channel. This fourth-generation HyperStream architecture delivers enhanced performance, reduced power consumption, and minimal digital noise for a perfectly black background.
Four THX AAA 78+ amplifiers—that is, eight op-amps operating in parallel in a four-channel balanced configuration—deliver remarkable power and finesse. In desktop mode, the output reaches 650 mW + 650 mW in balanced mode and 270 mW + 270 mW in unbalanced mode.
Powered by the 16-core XMOS XU316 controller, the KA17 features a precision 10-band parametric equalizer with adjustable frequency, gain, and bandwidth settings via the app or the FiiO website. The dual quartz oscillator ensures stable transmission and broad compatibility.
A D.Mode switch activates desktop mode, which optimizes the DAC, power supply, and amplifier stage to unleash their full potential. A second USB Type-C port dedicated to external power prevents the device from draining your device’s battery. A 0.91-inch dot-matrix display, an SPDIF output via the 3.5 mm jack, and multiple protective features round out the package.
