I found a Bryston Pi for ~$600. Took a few weeks to get it up and running, had to get a new OS snail mailed from Bryston. Manic Moose interface is spartan compared to my Sonos. iPad Safari is particularly annoying. Nice not to have another app to deal with. I am comparing it to various digital sources now (Wyred for Sound mod’s Sonos, iPad streaming 16/44 radio). So far I really like it. The big knock for me is the Radio Paradise app that plays FLAC does not work and it only appears to stream Tidal and Qobuz. Prolly find another place to use the old Sonos zone player until Sonos kills it with a software update. Use my iPad to stream Radio Paradise FLAC. Use the Pi to stream Qobuz and play Higher Rez file purchases.
