Hi @hysteve, in my experience a good switch has greatly improved my digital front end.
Standard Netgear = meh
EtherRegen = good
Bonn 8 = good
Network Acoustics Tempus = great
JCAT M12 = great
GTT / DeJitterit = great
Also a good Ethernet cable as last cable into Streamer or DAC
Additionally, the Network Acoustics Muon Pro filter is very nice.
This is all tried in my system and my findings!
