FIIO’s newly self-developed four-channel fully differential 24bit R2R DAC consists of 2x 48 precision thin-film resistor arrays per channel, totalling 192 resistors with 0.1% tolerance and low temperature drift (30ppm). This configuration delivers a unique and charming sound.
Comparison between fully differential and typical architectures
The K11 R2R employs a fully differential architecture, resulting in lower noise, with less FFT harmonics and a darker music background compared to typical ones.
2.
Dual NOS/OS modes
Double the fun
NOS (Non-Oversampling) Mode: Maintains the original sampling rate for decoding, preserving authentic sound and allowing you to enjoy an organic and captivating musical experience.
OS (Oversampling) Mode: Upsamples globally to a high sampling rate of 384kHz, for superior audio performance and even more refined, clear sound.
3.
True · 24bit decoding
Excellent capabilities, outstanding sound quality
Support for PCM 384kHz/24bit and DSD256 decoding, means the K11 R2R can easily handle high-precision audio signals and fully exhibit the details within, providing you with an excellent audio experience.
* DSD256 requires setting the DSD output mode to Native on the source device, internally converting to PCM before being decoded by the R2R resistor arrays.

NJW1195A
High-quality electronic volume control
The NJW1195A is a 4-channel electronic volume controller. This resistor ladder electronic potentiometer is low distortion and low noise, allowing precise volume adjustment.
5.
3 gain levels
3 independent volume curves
The 3 independent gain levels and volume curves allow the K11 R2R to give you a better listening experience with various types of headphones, whether you are using sensitive earphones or harder-to-drive over-ear headphones.
