Sonore Rendu, et. al., vs. Roon Rock USB Direct

Isn’t the output of the Sonore, and the input to the DAC, a “DIGITAL” signal? Which means it either goes through or it doesn’t? There is nothing like a bad digital signal, it is either 0 or 1.

The “digital” signal coming out of the PC/MAC/iPAD, should be exactly the same as Sonore’s output signal. And all what matters is the quality of the “Analogue signal coming out of the DAC…

Does that make the Sonore Rendu an heck of a snake oil? Or am I missing something significant here?
