I initially had a problem getting it linked to my Wi-Fi which was remedied by placing the unit in the same room as my router. The only downside is the HEOS app working with Alexa. But the sound quality is excellent, especially when you factor in the sub-woofer.
Not good at voices, so not good for TV. Pumps music fine, but it has no remote. Can’t get the app to recognize my TV to share that remote. Too much messing around. Had my eye on Sonos and Bose but this went on sale. Guh.
