FiiO K13 R2R

FiiO K13 R2R DAC Headphone Amp.  

Coming Soon

Desktop 24 Bit Fully Balanced R2R DAC and upgraded headphone amp. Outstanding features allow you to customize the audio your way, like choice of OS / NOS (oversampling or non) and integrated 10 band parametric EQ.

Adjustable lighting so you can select the colour on the dials and top side wiindow. Includes bluetooth 5.4 input with LDAC for high quality streaming to the DAC. 

Much Loved Resistor Array 24 Bit R2R DAC

The K13 R2R uses FIIO’s proprietary four-channel fully differential 24-bit R2R resistor array DAC, which is composed of 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. In addition, the NOS (Non-Oversampling) and OS (Oversampling) modes bring two different listening experiences. As shown below:

Robust Headphone AMP

Boasting a balanced output power of 2400mW in a 32 ohm load, FiiO K13 R2R can effortlessly drive both high fidelity IEM's and full size headphones, unlocking their full potential and allowing them to render every last detail.

K13 R2R is designed with DC/AC dual power supplies. The 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.

What’s more, the internal power supply materials never compromise. With 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 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.

Preamp, Desktop Audio Hub

With a wide variety of inputs and outputs, the K13 R2R 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.
