R2R Decoding
This player uses a true R2R DAC architecture rather than a conventional delta-sigma design. Resistor ladder conversion emphasizes precise voltage steps and natural timing, which many listeners associate with a grounded, analog-leaning presentation. FiiO pairs this with selectable OS and NOS modes, letting you choose between oversampling for precision or non-oversampling for a more direct signal path.
