@tonywinga @carlsbad2 Thanks for the information. I apparently wasn’t clear in my question. ALL of my audio system connections are hard-wired. The network dedicated backbone, i.e., router to router only, is a 5 GHz high bandwidth wireless connection. The audio streamer/server is connected by Ethernet to a router.
I can’t use Ethernet for the router to router connection due to the house design without incurring an unacceptable cost.
I have a separate home theater system with an Apple TV 4K. I’ve tried both Ethernet and wireless connections and prefer Ethernet because I get zero dropouts on 4K Dolby Vision, Dolby Atmos sound movies.
‘I’ve never had a dropout or glitch in the separate audio system music streaming. I’m just looking for best sound possible.
