FIIO K17 R2R

The FIIO K17 R2R is a high-end desktop DAC and headphone amplifier that combines the warm, natural sound of a classic R2R DAC with the latest streaming technology. Thanks to the exclusive 24+5-bit R2R PRO DAC, a fully balanced audio architecture, and a powerful discrete Class AB headphone amplifier, the K17 R2R delivers an exceptionally musical and detailed listening experience. With support for Roon Ready, AirPlay, QPlay, and NAS playback, this all-in-one solution serves as the ideal centerpiece of any high-end desktop Hi-Fi system.

Timeless design with natural materials

The K17 R2R stands out not only for its performance but also for its stylish design. The combination of a sleek aluminum chassis with side panels made of genuine North American ash or black walnut creates an elegant look that blends classic and modern elements. Because every wood grain is unique, each unit has its own character. The high-quality finish, intuitive knobs, and efficient heat dissipation round out the design.

Exclusive 24+5-bit R2R PRO DAC

At the heart of the K17 R2R lies FIIO’s proprietary 24+5-bit segmented R2R PRO resistor ladder. Thanks to an advanced architecture featuring thermometer-coded resistors, the inaccuracies traditionally associated with R2R converters are significantly reduced. This results in a sound reproduction known for its warm character, natural detail, smooth presentation, and excellent musicality. The result is a listening experience that is both refined and consistently enjoyable over time.

Extensive streaming options

The FIIO K17 R2R supports virtually every modern method of music playback. Thanks to its Roon Ready, AirPlay, and QPlay certifications, the device integrates seamlessly with existing streaming services and devices. In addition, the K17 R2R supports network playback from a NAS server via SMB and NFS protocols. Through the FIIO Control app, users can easily access their entire music library, both locally and via the home network.

Eight different operating modes

The versatility of the K17 R2R makes it suitable for virtually any listening setup. The device functions as a streaming player, USB DAC, and Bluetooth DAC, and also supports optical, coaxial, analog RCA, and balanced XLR inputs. Local music files from USB storage or a network server can also be played directly. This makes the K17 R2R a central hub for both digital and analog audio sources.

Professional 31-band lossless PEQ

For optimal control over sound reproduction, the K17 R2R features a highly advanced 31-band parametric equalizer. The powerful DSP processes all settings with 64-bit floating-point precision, ensuring that sound quality is fully preserved. Users can precisely correct frequency responses or adjust them to suit their personal preferences. Equalizer profiles can be easily saved, shared, imported, and exported.

AUTO EQ for Optimal Performance

In addition to manual settings, the K17 R2R features AUTO EQ. This function automatically applies an appropriate frequency curve to compatible headphones, instantly creating an optimal listening profile. In addition, various preset sound profiles are available for genres such as pop, jazz, and classical music. Of course, all settings remain fully customizable to your personal preferences.

Powerful, Discreet Headphone Amplifier

The fully discrete Class AB amplifier is designed to drive both sensitive in-ear monitors and demanding high-end headphones with ease. Thanks to high-quality transistors and a carefully engineered amplifier circuit, the K17 R2R delivers impressive output power, resulting in a powerful, controlled, and dynamic sound reproduction with an exceptionally natural tone.

Fully balanced audio architecture

From the DAC to the headphone output, the entire signal path is fully differential. This fully balanced architecture minimizes crosstalk and distortion, while significantly increasing dynamic range. High-quality operational amplifiers from Texas Instruments also ensure extremely accurate and stable signal processing.

Separate circuits for maximum sound quality

Inside the K17 R2R, the digital circuits, analog audio circuits, and power supply sections are completely separated from one another. This physical separation prevents unwanted interference between the various components and ensures a cleaner audio signal with greater detail, clarity, and transparency.

High-Quality Linear Power Supply

To ensure a stable power supply, the K17 R2R is equipped with a specially developed linear power supply. Combined with a generous energy reserve provided by high-quality capacitors, the device has sufficient reserves to deliver a constant and clean supply voltage. In addition, the analog and digital circuits are powered separately, minimizing noise and crosstalk.

Highly accurate clock signals

To process digital audio signals as accurately as possible, the K17 R2R uses multiple femtosecond crystal oscillators with ultra-low phase noise. These highly precise clock generators significantly reduce jitter and ensure that music is reproduced faithfully, stably, and with maximum detail.

High-quality components

Only high-quality audio components from renowned manufacturers were selected for the internal design. Premium capacitors, high-quality cabling, and gold-plated connectors work together to ensure a stable power supply and extremely pure signal transmission. As a result, the K17 R2R delivers an impressively spacious soundstage with an exceptionally low noise level.

Dual-core architecture

The combination of a powerful multicore processor and an energy-efficient network processor ensures fast operation and stable performance. Both streaming services and local music files are processed smoothly, while the user interface responds quickly to every command.

Intuitive operation

The K17 R2R’s controls are designed for maximum ease of use. The large 3.93-inch touchscreen provides direct access to all functions, while the multifunctional rotary knobs ensure fast and precise control. The included aluminum infrared remote control allows you to comfortably adjust settings from your listening position. Additionally, the FIIO Control app makes it easy to manage various functions directly from a smartphone or tablet.

Comprehensive Security

To provide optimal protection for both the device and any connected headphones, the K17 R2R is equipped with multiple safety systems. These include temperature protection, overload protection, DC protection, and overcurrent protection, which ensure that the device continues to operate safely under all conditions.

Wired and Wireless Connections

The K17 R2R supports both wired and wireless network connections. The Gigabit Ethernet port enables a fast and stable connection, while the built-in dual-band Wi-Fi module supports both 2.4 GHz and 5 GHz networks. This allows even high-resolution lossless audio files to be streamed seamlessly.
