I appreciate both of your comments and impressions. Both of you speak from genuine hands on and listening experiences. As has been readily understood, much of this is individual circumstances influenced. So naturally different solutions for varying situations.
I have a 2 story (4600SF) plus a finish basement (3rd level) where my audio system resides. My modem and separate router are in a 1st floor library. Bill (grannyring) has suggested a high quality modem/router combo unit and this is very appealing for me. Broadcom chip rather than Intel chip (sns 😊).
I am leaning toward this combo unit in my audio room connected via the Muon filter system to the audio streaming component (Yet to be chosen). This for for me would be a very simple yet effective and clean ethernet network circuit. My thought is the Muon is sufficient and would eliminate the need for a switch (Which entails another box/LAN cable/LPS/power cable). I just prefer simple.😊
