Desktop DAC and Headphone Amplifier
FiiO - K13 R2R (Black)
Unlock Your Best MixesThe FiiO K13 R2R features a proprietary four-channel fully differential 24-bit R2R resistor array DAC, featuring 48 precision thin-film resistors per channel, for a total of 192 resistors across four channels. Each resistor features 0.1% accuracy and low temperature drift (30ppm). This R2R DAC allows the K13 R2R to deliver a uniquely rich and musical sound, and employs a fully differential architecture that leads to lower noise, and fewer FFT harmonics, resulting in a darker music background.

Please note: The images used below are for display purposes only. This is the Black model.
Dual NOS/OS Modes Double The Fun
NOS (Non-Oversampling) ModeMaintains the original sampling rate for decoding, preserving authentic sound and allowing you to enjoy an organic and captivating musical experience.
OS (Oversampling) ModeUpsamples globally to a high sampling rate of 384kHz, for superior audio performance and even more refined, clear sound.
The K13 R2R supports 1Bit DSD native decoding. When playing DSD tracks, slightly lower volume is a normal phenomenon. It is recommended to adjust the volume to a normal listening level. In this mode, the menu setting SAM:OS will be disabled. In different modes, the actual listening experience may vary depending on various subjective and objective factors. Please refer to your own personal listening experience.
Preamplifier + Power Amplifier Output
Desktop Decoding HubWith a wide range of inputs and outputs, this unit functions as both a preamplifier and a power amplifier, catering to various listening preferences.
It also supports PCM 384kHz/32bit and DSD256 decoding, allowing it to effortlessly process high-resolution audio signals to deliver rich sonic detail and for an outstanding listening experience.
Ten-Band High-Precision PEQ
Effortless Sound CustomizationThe K13 R2R, with the help of the XMOS XU316 platform, features specially-developed PEQ, with support for 10 frequency band adjustments across all operating modes.
With FiiO's proprietary tuning algorithm, accessible through their app or web interface, you can easily utilize preset tunings like "Retro PEQ", or even simulate and correct headphone frequency response curves. It also supports exporting, importing, sharing, and saving EQ curves, and auto-EQ, making sound tuning effortless.
Specially-Designed Power Supply
DC/AC Dual power suppliesThe built-in 30W switching power supply is protected by an alloy nickel-plated shielding cover, which significantly boosts its anti-interference capabilities and ensures a cleaner power supply.
Additionally, it also features an external DC power input, allowing you to pair it with a higher-performance linear power supply for a different sound experience.
Fully Balanced Audio Amplifier Circuit
ultimate clarityThe entire audio chain, including the R2R DAC, LPF, volume control, and headphone amp, uses fully differential signal processing for excellent interference rejection, minimal distortion, and high dynamic range. The amplification circuit also features gain control, headphone protection mechanisms, and POP noise elimination for a robust and reliable audio experience.
Multi-Rail Power Supply
Robust performanceWith up to 18 low-noise LDOs and 5 DC-DC converters in total, this unit employs a multi-rail power supply to provide strong and clean power for exceptional audio output.
Premium Features
ELNA RA3 audiophile-grade electrolytic capacitorsPremium ELNA RA3 series silk-film audio capacitors and specialized audio tantalum electrolytic capacitors work together to ensure a pure, stable power supply for the device, delivering a warm and natural sound.
Robust output Revealing every last detailWith a balanced output power of 2400mW+2400mW into a 32Ω load, the K13 R2R can effortlessly drive both high-fidelity IEMs and headphones, unlocking their full potential and allowing them to render every last detail.
Superior screen ClarityA custom, high-contrast, long-lasting HD LCD display clearly shows the device's current status at a glance, including sampling rate, volume, gain, and output mode.
Adjustable RGB logo lightingWith support for Bluetooth 5.4 and reception for the LDAC/AAC/SBC codecs, the K13 R2R allows you to be immersed in a world of high-quality music even when listening wirelessly.
Precisely Designed Perfect Performance
Three gain levels, three independent volume curvesDifferent gain levels mean the K13 R2R is better able to adapt to various kinds of IEMs and headphones for better listening experiences. Moreover, volumes of PO and PRE can be memorized independently.
Overheating protection, overload protectionProtection mechanisms will automatically kick in when abnormal operating conditions are detected to avoid damage to the unit, making it safer to use.
Adjustable RGB lightingNot only does the RGB lighting indicate the current audio sampling rate, but you can also customize the brightness, colours, and whether it pulses or not.
1-99 minutes timer shutdownConvenient functionality, meeting your needs. Timer shutdown works one time after being set each time.
