All great suggestions. Thanks everyone. It's correct that sometimes you have to compromise. I'm wondering if my compromise should be no wireless speakers in the garage/dining room and just run wires to those places. Lord knows that wires always work at least. Critical listening is done in the main room and not with Pandora, but we use Pandora constantly in the summer months with the outdoor speakers. I find it great for discovering new music and consistently playing good selections - unlike Spotify radio for example, which sure plays a lot of garbage IMO.
Last night I got into looking at Volumio on a RaspberryPi. Seems like I can stream anything to that with a DAC Hat on the Pi to provide a digital output to a real DAC and then to the stereo. https://volumio.org/
Or perhaps my compromise should be the "Master" quality tracks on Tidal, and just go with the Sonos Port. If the Volumio thing doesn't work out, I'm definitely going to have to do a compromise I think. Classic consumerism issue.
