Respectfully, isn't that comparing Apples and Oranges (pun unintended)? Kali probably has superior audio to OG HomePods or Sonos, but are they capable of multi-room as is? Are they compatible with Airplay 2? I think they can be adapted to work with bluetooth (adapter required, if I'm not mistaken) but IMNSHO, Airplay is far more versatile and responsive that BT is (although I bet newer revs of BT are catching up... have caught up? Don't know).
Disclaimer: I am not an audiophile. I simply enjoy decent sound which can work with multi-room and plays nicely with Airplay 2. Because of that, I enjoy HomePods and probably would appreciate Sonos as well if I were to dip my toes into that particular eco-system.
Another thing I really like about the OG HomePod is how well it syncs video to audio, making it a very respectable alternative for TV viewing (I do wish that Apple would find their way to supporting a true 5.1 or 7.2 system, making use of HomePod audio features).
That said, I acknowledge that Kali sure sounds like it would be a superior sonic experience... but I return to my original question. Are we not comparing entirely different solutions?
