I've been continually impressed with Sonos.

I spent $2-3k on a full Sonos setup over a decade ago, and everything* is still fully supported and works perfectly. Without a subscription fee!

Sonos is the only company whose hardware I'm using 10 years later, outside of large home appliances.

Edit: Oh gosh, the sentiment in the other HN thread is literally the opposite as mine. Bracing for downvotes. I'm surprised that others have had such a bad experience.
