I guess some people just can't bring themselves to be helpful. It's easier to make inane comments.
Those instructions are for bypassing the Hegel's internal DAC and using an external DAC instead. In your case the Hegal will not be sending anything to the X1. Instead, just connect the X1 to one of the Hegal's inputs and stream from the X1 like I assume you're doing now (Qobuz/Tidal over your network?) and enjoy the superior DAC in the X1. I can't remember if the X1 has RCA and XLR or just XLR outputs (my T2 has both) but XLR is preferred. You can use the volume control on the Hegal or just set it at a comfortable level and use the Leed volume control on the X1.
