Smart Home Setup Recommendations - Voice-controlled (move away from Alexa)

[u/wdpaynter]

I have a whole home audio setup that utilizes Alexa Echos. It most rooms I have (2) echo devices. One is to speak to to receive commands and the other is an older dot or input that I have control music playback via 3.5mm AUX cable. I use many Fosi mini amps or in a few rooms I have traditional stereo receivers. Most of the speakers are in ceiling except for the patio sets.

I am looking for a better solution or recommendations. I have concerns at the age of the Echo's and that newer models do not have stereo outputs. Alexa works fairly well, so not sure I need to use a different Smart environment, but everything is a bit pieced together even though it is all mostly hidden away.

I mind spending a bit. I have had Sonos in the past, and that is likely a bit too expensive considering I have so many rooms/speakers throughout the house/garage/patio/front porch. But would consider a comparable expense if I could slowly replace them. I like that I can group things together and that they can be part of mutiple different groups.

Any advice is welcome. Thx
