Optical output means it’s not really being decoded by a DAC. It’s just sending digital data. The decoding then happens at the DAC or in the amp/receiver. In other words, the data coming out of this should be just as good as any other data, no matter how expensive the player. That’s what digital is. It’s ones and zeros. If it gets there intact, it’s either all there or none of it is.
