FiiO teases the K17 R2R Pro, a resistor-ladder DAC and amp with Wi-Fi
Coming mid-2026, the K17 R2R Pro uses a proprietary resistor-ladder architecture in place of a conventional delta-sigma chip, with global pricing announced in June.
FiiO has teased the K17 R2R Pro, a desktop DAC and headphone amplifier arriving mid-2026 that uses a proprietary resistor-ladder (R2R) architecture rather than an off-the-shelf delta-sigma converter, with network features including Wi-Fi. Global pricing was set to be announced in June 2026.
R2R is usually sold on the promise of a more analogue presentation. What it reliably changes is measurable: R2R implementations typically show different distortion and linearity behaviour at low levels than delta-sigma parts do, and whether those differences are audible in normal listening is a much older argument than this product. The numbers will tell most of the story here.

More new DACs
FiiO swaps the R7's delta-sigma converter for a resistor ladder in the R7 R2R
The all-in-one desktop streamer, DAC, preamplifier and headphone amplifier returns with FiiO's own R2R converter in place of the ES9068AS, at around $700.
Fosi Audio shows the ZH1, a dual-CS43131 desktop DAC for around £130
Shown at CanJam London ahead of a September release, the ZH1 puts two Cirrus Logic converters and more than a watt of output in a hexagonal chassis, for roughly £130.
Topping rebuilds the DX1 as the $119 DX1 II, with a balanced output and PEQ
A ground-up revision at $119: an ES9039Q2M converter, a four-channel amplifier stage, a 4.4 mm balanced output, optical I/O, a microphone input and a 10-band parametric EQ.
This is an announcement, not a verdict. Specifications come from the manufacturer and nothing here is measured until a unit reaches the rig. For tested dacs, see DACs reviews. Back to all new releases.
