The problem with the FiiO R2R is the resistor tolerance. No high-precision resistors, no compensation circuitry or algorithms, and even no audio quality control. Therefore, the parameters of each unit are different, and the left and right channels are also different. Such a poor design cannot possibly claim high fidelity. Oh, that's the reason they can make affordable/budget R2R products. Of course, their users don't care about this.
