Chord mscaler - what’s connected and Settings used

curious to know what is connect to your mscaler.  I plan to connect mine directly to a roon nucleus via usb from the mscaler.

And, how do you adjust settings when Mscaler is in use?

to clarify,
what levels on your mscaler do you set things at while listening?

Do you max out upsampling level? Or do u explore the range of flexibility. Curious to get an example of how this device is used while operating it.
