The K17 is a digital-to-analogue converter from FiiO, built around a sophisticated dual AK4499EX conversion configuration paired with an AK4191 digital filter chip. The K17 brings FiiO's more accomplished current engineering to standalone digital conversion.
Key specs that matter
The engine uses an AKM AK4191 digital filter chip paired with two AK4499EX conversion chips - an advanced dual-DAC configuration reflecting considerable engineering ambition. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio reaches 121dB, with total harmonic distortion plus noise at an exceptionally low 0.00053% at 22kHz - reference-tier figures for an accessible Chinese DAC.
Sound and use context
Expect exceptionally clean, detailed conversion reflecting the strong 121dB signal-to-noise and sub-0.00053% distortion figures, achieved through the sophisticated dual-chip AKM conversion architecture.
Pairing
FiiO's broader amplifier and DAC catalogue offers natural companion components for buyers building a coherently voiced, accessible FiiO-based system around this DAC.
Alternatives
FiiO's own K17 R2R Pro offers an alternative R2R conversion architecture within the same broader model range, worth comparing directly for buyers wanting to compare delta-sigma and R2R conversion philosophies.
