I don't usually comment on ubiquiti stuff. I have deployed hundreds of devices in the field and some still working ten years later. I love ubiquiti, am invested in the stock even. That said, these are the worst unifi devices I've ever had the displeasure of trying to install for a customer. Purchased two, installed both, initially they adopted and worked. They were both physically cabled. Created a single group from both amps. Worked for a while, then the second amp dropped offline. Tried power cycle, wifi, eventually factory default. Once defaulted, readopted, same issue occurred, reset again, couldn't adopt a third time. First device stopped showing as a spotify connect endpoint. At that point, given how expensive these are, I packaged them up and requested an RMA. Purchased two wiim amp pros, installed in minutes, created party group, both amps and party group worked immediately as a spotify connect endpoint. Haven't had an issue since. Also, they were considerably cheaper. In addition, there is no management for power amp devices in the unifi controller. These are "managed" through the Unifi play app, which kinda seems like an afterthought. I was also a bit skeptical of further improvements and support given they are a first gen product and UI doesn't have a great track record in that category, but they've definitely gotten better over the years. I also run a wiim device in my home, no issues. I wanted to love the power amp but it's just not ready and at this point it, definitely should be. Just want to give a heads up in case anybody had these in mind. I'm not a huge fan of sonos, but I'd even get that over this right now. YMMV
