Okay, if Moon gets back to me and says that you are right, I will try out a decent 75 ohm coax. I don't really play CDs all l that often. I mostly play the turntable and stream from the Moon 280D.
I was in the computer industry for years and even though I was in sales, I had to take a number of classes on various aspects of computing. Networking was one of them. I think that networking is done in packets. The transport sends a digital signal from its "digital out" optical and SPDIF cables. It sends an analogue signal through its RCA interconnects. Two different kinds of signals.
I would refer you to the nomenclature when streaming. Higher resolution albums come in 24 bit packets and lower resolution in 16 bit packets. So, to me that says that digital audio is sent in packets just like everything else. But I commit to looking into all of this more deeply and doing a test with a decent 75 ohm digital cable.
