Fiio K11 R2R vs regular K11, which one keeps frequency signals intact?
According to the manufacturer’s specifications, the FiiO K11 R2R Desktop DAC and Headphone Amplifier (Silver) is a true 24-bit DAC that allows for NOS (no oversampling) and OS (oversampling) modes. The NOS mode maintains the original sampling rate for decoding, which preserves an authentic sound and allows you to enjoy an organic and captivating musical experience. Alternatively, OS mode up-samples globally to a high sampling rate of 384kHz for superior audio performance and an even more refined, clear sound. The standard K11 model does not offer these modes.
