A brief update... I played Roon last night and it was virtually problem free. I had a hiccup or two, but surprisingly Roon did not disconnect and I didn’t have to reboot Roon. I had seen a number of prompts from Apple to update the OS on my Mac desktop and I finally did. Have no idea if that helped the situation.
I still am thinking about the Eero and another streamer like the all in one Bluesound Vault 2, but maybe my dollars would be better spent on a sub for the LS 50s or even upgrading the 50s xovers....or trying a full-range speaker
