Built for audiophiles and headphone enthusiasts who want a single component to replace a full stack of separates, the FiiO K17 R2R is a flagship all-in-one desktop DAC, streamer, preamp, and headphone amplifier. It handles everything from local playback to network streaming (Roon Ready, AirPlay, NAS support) to driving demanding headphones directly, making it equally at home as the centerpiece of a headphone desk or as a source/preamp in a stereo system.
Its standout feature is the proprietary 24+5-bit segmented R2R PRO resistor-ladder DAC, which delivers a warmer, more natural analog-like sound compared to typical ultraclean formats. The K17 R2R also packs a fully discrete Class-AB headphone amplifier capable of up to 4000mW per channel in balanced mode, providing headroom for hard-to-drive planar magnetic and high-impedance headphones while remaining clean for sensitive IEMs.
Connections are fully balanced throughout, with XLR, 4.4mm, and 6.35mm outputs, plus USB, coaxial, optical, Bluetooth 5.1, Wi-Fi, and Ethernet. It includes a 31-band lossless parametric EQ with Auto EQ support, a 3.93" touchscreen, NOS/OS switchable modes, and ships with an aluminum alloy infrared remote. Genuine wood side panels and a machined aluminum chassis complete the premium aesthetic.
