Over in this thread, @Mark_Brown points out that you can disconnect the ethernet cable from your overpriced ethernet switch, and the music will continue to play (until the buffer is exhausted).
So, my question to you is: when you disconnect the ethernet cable does the SQ
- improve,
- get worse or
- stay the same?
Even better, have a friend connect/disconnect the cable and see whether you can “hear” whether it is connected or not.
