I have made a big "investment" in SONOS kit. My rationale? Sound quality is plenty good enough for me. Interface and features are good enough for me. The idea that this baseline will degrade over time is not something I want to deal with. It looks like "smart" speakers are a "dumb" choice. Better to get dumb speakers with stupid wires and connect them to disposable sources. That's the genius I'll go forward with. Lesson learned for less than $10k. I have experienced worse. Come to think of it, I hate Apple Music. We peaked at "iPod hard wired into your audio system with remote control of the iPod". Go ahead and say it. "OK, Gen X. Time for your nap."
