Description Fully differential true 24Bit R2R resistor arrays 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. Preamplifier power amplifier output, desktop decoding 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. Specially-designed power supply The 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.
