FiiO K17 R2R Desktop DAC and Headphone Amplifier Silver

FiiO K17 R2R Desktop DAC and Headphone Amplifier Silver

At the core of the K17 R2R is a proprietary 5 + 24-bit resistor ladder (R2R) DAC design. This architecture is intended to deliver a more analogue-style presentation, with support for both NOS (non-oversampling) and OS (oversampling) modes. Users can switch between these modes depending on preference and source material.

AMPLIFICATION AND POWER OUTPUT

The unit incorporates a discrete Class AB headphone amplifier stage with a quoted output of 4000mW per channel. This level of power is designed to accommodate a wide range of headphones, from in-ear monitors to more demanding planar designs, while maintaining control and dynamic range.

CONNECTIVITY AND STREAMING

As a combined DAC and streamer, the K17 R2R supports local playback alongside wireless and wired streaming. Connectivity includes dual-band Wi-Fi (2.4GHz and 5GHz), Gigabit Ethernet and QPlay support for compatible devices, enabling network-based audio playback within a home setup.

FIIO K17 R2R SOUND CUSTOMISATION

A 31-band parametric equaliser with Auto EQ functionality is included, allowing detailed sound adjustment. Settings can be configured via the FiiO Control app or through a web browser, with profiles stored directly on the device

DESIGN AND FEATURES

Additional features include a USB ground loop isolator aimed at reducing noise when connected to digital sources and a 35W low-noise linear power supply. The front panel is dominated by a 3.93-inch touchscreen providing access to playback controls, settings and visual displays such as VU meters. An aluminium infrared remote control is also supplied.

The K17 R2R is designed to operate both as a standalone headphone amplifier and as part of a wider HiFi system, offering flexibility for different listening setups.
