Yeah, exactly this. The original comment misses a key point: speakers have been the same for decades, but Sonos did add magic sauce that builds on top of that legacy... multi-room audio. I'd argue that's worth the investment, and it's a really great improvement to the audio experience. That's hard to achieve without re-wiring your entire house, and arguably worth the risk/bet on Sonos, which has had a historically really good track record with these things.
