My speakers are dialed in tight. I geeked out and pick up a Prexiso laser measurement gizmo off Amazon. Best toy ever! I was surprised to discover how off my speaker placement was.
Network Acoustics Muon Ethernet Filter really has my interest. I like that it’s a non-powered filter but it’s expensive. It’s placed between the switch/router and the streamer. Thing is, they recommend that a short line of ethernet is used between the Muon and switch/router. The distance from my streamer to router is a good 15 feet away so idk of the Muon would work in my application.
