I tried hooking up a Matrix Element M2 tonight in my office to Cat6 a few feet from a 10Gbps switch and there was significant pops and crackles coming thru.
Disconnected the cable and used wifi - dead silent.
Well at least I actually tried it. Common knowledge ethernet can introduce electrical noise especially in locations with computers and other electrical gear. Google it sometime.
Enjoy the popcorn.But I'll have a scotch 🥃
