I am interested in the Unison.. I have 3 systems in my house. The basement system is surround sound. It doesn’t currently have a streamer since a Bluesound Node died about a year ago, except for anApple TV. The ATV will only play compressed files and it won’t recognize my Melco N100 server that Feeds the other two systems. Otoh I don’t really wish to do much in the way of 2 channel streaming down there, but every now and then I get the urge. So I don’t want to spend much there. I already use an Anthem AVR with ARC down there so I assume it would just be plug and play.
My reservation is Play Fi. Before the Pandemic I bought a Arcam streamer that used Play Fi. It didn’t work for anything besides Internet Radio. It was unable to interface with my server which at the time was a popular Synology model that worked fine with other streamers Both Arcam and PlayFi did not respond to CS inquiries, so I was never able to nail down the culprit, and wound up returning the streamer within the allotted time window. The lack of any response from Play Fi was most troubling. That was several years ago and perhaps they have better CS now but as I type this the whole unpleasant experience is coming back to me and I think I have talked myself out of buying the Unison..
I would be interested in hearing the experiences of others besides @kota1 who have purchased this unit, or anyone who uses PlayFi
