@alan60 I recommend you try iFi into network extender then from there use a really nice Ethernet cable into your streamer. I use this iFi gizmo and I can tell you it doesn’t harm anything. In my system it doesn’t improve anything either but it’s cheap enough to keep in the chain. A really good Ethernet cable should yield a bigger improvement than adding a filter to a cheap generic cable. My experience. YMMV.
