I've used Eero with Sonos. In one case the Sonos system was not in a location that could be wired and I used DSL --> Eero <-wireless-> Eero --> BOOST <-wireless-> SonosNet.

With any of these Mesh systems, place a node about halfway between the previous node and an area you want to cover. And, if you have the opportunity to set transmit power, don't necessarily go for the max because you could create a situation where the client sees a nice signal from the access point, but the client is actually out of range and does not have enough power to transmit back to the access point.
