Marantz Stereo 70S AV Receiver | 2-Channel x 75W

The Marantz Stereo 70S is a two-channel AV receiver that bridges traditional stereo performance with modern streaming and HDMI connectivity. Delivering 75 watts per channel into 8 ohms, it serves music-focused listening rooms and compact home theater setups where a slim, uncomplicated receiver is preferred over a multi-channel unit.

Six HDMI inputs accommodate a range of source devices, with support for resolutions up to 8K and video formats including Dolby Vision, HDR10+, HLG, and Dynamic HDR. Audio streaming is handled through HEOS, AirPlay 2, Spotify Connect, and Amazon Music, and high-resolution file support includes FLAC HD 192/24, WAV 192/24, and ALAC 192/24. Two subwoofer outputs allow for flexible bass management, and the 3U chassis keeps rack depth to 14.7 inches.
