A compact streaming amplifier that punches above its size The Marantz Model M1 is a compact wireless streaming amplifier that puts a full HEOS streaming platform, HDMI eARC and 100 watts per channel into one small, made-in-Japan chassis. It is built to drive a real pair of speakers for both music and television. Think of it as a hi-fi source and amplifier in a single box. Why You'll Love It 100 watts a channel from a small box. The Model M1 delivers 100 W + 100 W into 8 Ω with very low distortion, enough to drive real bookshelf or floorstanding speakers. Streaming built in. HEOS, Spotify Connect, AirPlay 2, Tidal and Bluetooth are all on board, so the M1 streams from almost any phone, tablet or service without an extra box. It upgrades your TV too. An HDMI eARC input takes clean audio straight from the television, and a subwoofer output lets you add bass for 2.1 sound. Under the Hood Full high-resolution support. The Model M1 handles 24-bit/192 kHz PCM through FLAC, WAV and ALAC, plus DSD at 2.8 and 5.6 MHz, which is unusual at this size. Made in Japan. Marantz builds the M1 in Japan with a 4 to 16 Ω speaker rating and 4-way binding posts, so it is comfortable with a wide range of speakers. Wired or wireless, and controllable. Dual-band Wi-Fi and Ethernet cover the network, and it integrates with Crestron, Control4 and AMX control systems. CHT Insider Verdict The Model M1 is the neat answer for anyone who wants serious sound without a rack of separates. It suits a living room, a study or a bedroom system where space is tight but sound quality still matters, and the eARC input means it doubles as a tidy TV amplifier. For its size, there is very little it leaves out. Pro Tip: Connect the M1 to your TV over the HDMI eARC port rather than optical if you want lip-sync handling and volume control from the TV remote. Optical works, but eARC is the cleaner path for everyday viewing.
