Stream music your way

HEOS built-in lets you play music from services including Spotify, TIDAL, Amazon Music, Deezer and TuneIn, and group the MODEL M1 with other HEOS products around the home. AirPlay 2, Bluetooth (receive) and Spotify Connect are also supported.

It plays FLAC up to 24-bit/192 kHz, ALAC, WAV and DSD (2.8 and 5.6 MHz) from a network share or USB storage.

HDMI eARC and onboard Dolby Digital+ decoding let the MODEL M1 take sound from your TV. Marantz includes Dialog Enhancer and Night Mode sound modes, and TV Sound Grouping.
