More Than Meets the Eye: 75Wpc Slimline Marantz Stereo 70s AV Receiver Handles DSD 5.6MHz, Includes HEOS, and Features Six HDMI Inputs
The Roon-tested Marantz Stereo 70s AV receiver defies what’s possible in a slimline design that fits where most audiophile equipment cannot — and plays with a power, clarity, smoothness, warmth, and naturalism not possible from equipment at this price level even at the start of the 2020s. Outputting 75Wpc from a fully discrete amplifier, Stereo 70s handles DSD 5.6MHz and boasts HEOS multi-room streaming, six HDMI inputs, an MM phono input, an ARC output, dual subwoofer outputs, and even a pre-amp output for further expansion.
Home cinema with just two speakers? Stereo 70s makes it possible by leveraging the technology of Marantz’s full-size surround AV units. The company’s famed HDAM modules complement Pure Direct Mode to deliver size-belying sonics, and built-in Bluetooth and Wi-Fi further your connectivity and wireless options. Ditto compatibility with Alexa, Google Voice Assistant, and Apply HomePod. Over-the-air firmware updates, HDMI diagnostics, and control via the Marantz AVR app add to the reasons why this 4.3 x 17.4 x 14.7 component is a dynamo.
In addition to Stereo 70s, the shipping box contains a remote control, batteries, antennas, an Audyssey microphone, mic stand, quick-start guide, and more. For further support or any questions, give a Music Direct audio consultant a shout at 312-433-0200.
