Marantz Stereo 70s Network Receiver – 75 WPC, 2.2-Channel

Marantz Stereo 70s 2.2-Ch Network Receiver 75 WPC

The Marantz Stereo 70s is a landmark product — a slimline 2-channel stereo receiver that brings the full feature set of a modern AV receiver into an elegant, compact form designed around two speakers and a simple, beautiful living space.

The concept is genuinely clever: all the HDMI switching, 8K video, streaming, and subwoofer management of a full-size AVR, delivered through a purely stereo amplifier section with no compromise to the listening experience. At its core is a fully discrete Class A/B power amplifier producing 75 watts per channel into 8Ω (100 watts into 6Ω), built around Marantz’s proprietary HDAM (Hyper Dynamic Amplifier Module) circuit boards — discrete designs that replace the integrated op-amps found in most competitors, delivering measurably lower noise and higher slew rates. The result is the warm, spacious, and tonally rich presentation that Marantz has been refining for 70 years.

Six HDMI 2.1 inputs — three supporting 8K/60Hz — plus one ARC output make the Stereo 70s a natural hub for any modern home entertainment setup: smart TV, games console, streaming device, and turntable can all be managed through a single slim unit just 4.3 inches tall. Dual subwoofer outputs and a 2.2 multichannel pre-out section add substantial bass management capability. A dedicated MM phono stage handles turntable input directly. Streaming is comprehensive via the HEOS ecosystem, with AirPlay 2, Bluetooth, Wi-Fi, Spotify Connect, TIDAL, Amazon Music HD, and more all built in. A Pure Direct mode bypasses all processing for the most direct signal path to the amplifier.

The front panel presents Marantz’s characteristic port-hole OLED display, clean control layout, and front headphone output — all within a chassis that is half the height of a conventional receiver. The black finish is refined and unobtrusive.

This unit has been thoroughly inspected and tested to confirm full functionality and is presented in like-new condition in its original packaging with all accessories included.
