We use Heos all the time. I can also control it with Crestron. Have several homes with combos of Marantz AVRs with Heos, Heos Links (Source only) and Heos stand alone speakers all being controlled by Crestron. Sounds better than Sonos, treats us dealers better, lets me integrate. What's not to love?
