FiiO K17: a flagship desktop DAC/amp pairing an AKM AK4191 with two AK4499 DAC chips and a fully balanced discrete Class AB amplifier rated at 4,000mW per channel into 32Ω from its balanced outputs. It's for a one-box headphone system that streams over Wi-Fi or Ethernet (Roon Ready, AirPlay) and tunes headphones with a 31-band lossless PEQ.

Who the FiiO K17 is for

  • Demanding headphones: The balanced 4.4mm and 4-pin XLR outputs are rated at 4,000mW per channel into 32Ω and 950mW into 300Ω.
  • Listeners who EQ: The 31-band lossless PEQ corrects a headphone's tuning without a computer in the chain.
  • Network streaming: Roon Ready, AirPlay and QPlay certified, with NAS playback over dual-band Wi-Fi or gigabit Ethernet.
  • A whole-system hub: USB, optical, coaxial, Bluetooth and analog RCA or 4.4mm inputs feed one box, which also has XLR and RCA line outputs.
  • Skip it if: you need a compact unit: the K17 measures about 244.6 × 213 × 66.8mm and weighs about 2,750g.
