TCP/IP over Ethernet using ARP is a quite a different story from S/PDIF. The main difference is in the multiple layers all buffered and running on high-speed. The S/PDIF isn't buffered and runs in real time (CD reads as fast as it reproduces). This gives the TCP layer running from say a hard drive (over an order of magnitude faster than an audio CD), more than enough time to re-transmit the information. Also, the way data is read from a hard disc is very different than from audio CD, audio CD's are read at a steady rate, and designed to have errors in reading, discs are designed to be "flawless".
I believe the correct English phrase is "Apples and Oranges". In my country we say something like "don't mix frogs and grandmothers"
