HEOS-capable gear from Marantz and Denon cover a lot of the applications you referenced. I decided I would never buy another Sonos product after the S2 rollout, and I now have a mix of eleven Denon and Marantz receivers driving both built-in, freestanding, and outdoor speakers of my choice all over my house.
HEOS is amazing for the size of the dev team, which I think is a couple folks somewhere in a large garage in Minnesota[0]. The amount of things they never touch is amazing. I appreciate the stability - my HEOS 1 speaker is still working, streaming tunein and tidal without issues - but when it comes to the app, it's borderline stagnation at this point.
They had a fairly unique and high-quality product in the early days.
It just did’t evolve very far or very fast, or even adapt pricing to better fit a rapidly changing market.
They switched away from a focus on multi-room hi-fi (or at least mid-fi) audio and users with their own hoard of digital audio to focus more on streaming services and chase the trend of little monophonic speakers. The higher-end devices remained good but became ever more niche.
Then they broke everything, particularly customer trust, with the app update.
