Description
Fully differential true 24Bit R2R resistor arrays DAC
FIIO’s proprietary four-channel fully differential 24-bit R2R resistor array DAC 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.
Comparison between fully differential and typical architectures
The K13 R2R employs a fully differential architecture that leads to lower noise and fewer FFT harmonics, resulting in a darker music background.
Preamplifier + power amplifier output
With a wide variety 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.
Multi-rail power supply – Robust performance
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.
High-quality ELNA RA3 audiophile-grade
Premium ELNA RA3 series silk-film audio capacitors and specialised 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 detail
Boasting 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 and clarity
A custom, high-contrast, long-lasting HD LCD* clearly shows the device’s current status at a glance, including sampling rate, volume, gain, and output mode.
*Long-lasting LCD, can always be on without risk of burn-in
Minimalist design – technological elegance
The thickened, unibody aluminium alloy casing, paired with a brand-new “skylight” design, not only continues the K11 series’ minimalist design language but also introduces a literal technological window into the R2R resistor series. The flowing light and vibrant colours showcase a unique tech aesthetic.
LDAC high-res Bluetooth – Truly enjoy wireless HiFi
With 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 curves
Different 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 memorised independently.
Overheating protection, overload protection
Protection mechanisms will automatically kick in when abnormal operating conditions are detected to avoid damage to the unit, making it safer to use.
Adjustable RGB lighting
Not only does the RGB lighting indicate the current audio sampling rate, but you can also customise the brightness, colours, and whether it pulses or not.
