FIIO K11 R2R Headphone Amplifier - DAC/AMP

Product description

PC PeripheralsHeadsets & AudioExternal sound cards from FIIO

K11 R2R Headphone Amplifier is a DAC/AMP from FIIO that offers advanced audio processing with a self-developed, four-channel fully differential 24-bit R2R DAC. This DAC uses dual 48-precision thin-film resistor arrays per channel, resulting in a total of 192 resistors with 0.1% tolerance and minimal temperature drift to ensure an unparalleled sound signature. The goal of the product is to provide a superior listening experience for headphone users.

The device is designed to offer excellent noise performance thanks to the fully differential architecture, which reduces unwanted FFT harmonics compared to conventional designs. It also features dual NOS (Non-Oversampling) and OS (Oversampling) modes, allowing listeners to choose between authentic, organic sound and high-resolution audio with upsampling to 384kHz. K11 RAR supports PCM 384kHz/24bit and DSD256 decoding, enabling it to handle high-precision audio signals with high integrity.
