Model 40n

Selora recommended

The Marantz Model 40n is a network integrated amplifier that combines a stereo amplifier rated at 70W per channel with a HEOS streamer, HDMI ARC, and an onboard phono stage. The local heos integration controls the HEOS side as a media_player for playback, volume, and multiroom grouping.

Works on integrations
Protocols
Roles it can fill
An integrated amplifier that drives passive bookshelf or floorstanding speakers and joins Home Assistant as a HEOS media_player. Control, grouping, and volume work locally with no account. An optional HEOS account is only needed for streaming favorites and playlists in the integration options. HDMI ARC accepts TV audio, and the phono input accepts a turntable. Connects over Wi-Fi or wired Ethernet. HEOS groups take a few seconds to form, so allow a short delay after grouping before playback.
