A wonderful, reasonably priced amplifier that’s far friendlier for non-audiophiles whereas nonetheless cranking out the model’s highly effective, heat signature sound
The Stereo 70s built-in receiver/amplifier isn’t celebrating the Nineteen Seventies. As a substitute it’s a commemoration of 70 years of constructing amplifiers; in 1953, Saul Marantz based the corporate in New York Metropolis. The Marantz model is, in the present day, fairly completely different; the corporate’s wares are largely Japanese, manufactured in its Fukushima facility that’s been there for the previous 22 years. That transition from NYC to Japan occurred over a long time, because of devoted audiophiles in that nation and manufacturing capability that was rising within the Sixties and ’70s, whereas it was shrinking within the US.
It’s best to care concerning the Stereo 70s as a result of it’s reasonably priced for an merchandise from a model with a reasonably legendary audiophile pedigree, and it’s dead-simple and un-intimidating to make use of. “Sadly,” Gary Dayton, Senior Product Planner at Marantz says concerning the fame of higher audio elements, “there’s been an impermeable intimidation wall no matter whether or not you possibly can afford higher audio merchandise. Customers have simply been taught it’s a ache within the ass.”
In response to that notion, Marantz designed the Stereo 70s with paper directions that have been easy to comply with. Unbox the unit and it tells you what to plug in the place. As quickly as you’ve strung an HDMI wire out of your TV to the clearly labeled HDMI port you’re in a position to comply with on-screen directions, and getting the unit to work with a pair of audio system (or a soundbar), turntable and/or CD participant is all super-simple. In reality it’s nearly breathtakingly antithetical to the remainder of the electronics world. As soon as setup was full, it was additionally easy so as to add the Marantz to a house community after which allow AirPlay (so you possibly can ship no matter’s enjoying in your cellphone to the receiver). Additional, should you use a better bitrate streaming service, reminiscent of Roon (which we like, as a result of it allows management of our personal library in addition to higher-fidelity streaming) the Marantz will auto-populate it as an output.
Plus, an app referred to as HEOS (for Android and iPhone) is built-in with the Stereo 70s. It helps you to talk with the receiver out of your cellphone and stream from sources like Spotify, Tidal, SiriusXM, SoundCloud and about 10 extra providers, in addition to from tracks natively saved in your cellphone. Your cellphone turns into your distant, too, since you possibly can select from all of the amp’s wired sources like phono or CD, in addition to video sources, reminiscent of an Apple TV. The included distant is much much less essential with HEOS.
Dayton explains two selections about this one-stop app answer. “First, we’re not making judgment calls for patrons,” the place, with out naming names, different extra hidebound manufacturers would possibly wish to curate what you possibly can stream. “I obtain lots of stuff from Bandcamp or simply self-published or in any other case under-available on streaming providers sources. I can play that simply as simply via my Marantz tools as I can a Spotify playlist that my daughter sends me.”
As for making playback simpler, that was crucial to Marantz’s considering, particularly for video integration. “Traditionally there was a reasonably excessive diploma of inconvenience; you couldn’t simply activate the TV and have it robotically change to your amplifier. Now it robotically switches.” That is no matter whether or not you have been simply enjoying music via a streaming service or the amplifier was off. Likewise, change off your TV and the entire system powers down. “This restores the expectation of comfort that we’ve had with sound bars or with the TV with out sacrificing any sound high quality.”
Not that any of that may matter if the sound was garbled—however simply the alternative is true. Throughout testing, whether or not listening to Joe Cocker’s superb 1970 dwell cowl of “The Letter,” a lossless recording on Apple Music, or Hank Mobley’s model of “Dance of the Infidels” on a Blue Be aware LP we picked up on vinyl in Tokyo, the sound staging and copy have been very good. Dayton attributes the readability and heat to a little bit of in-house technical wizardry, noting that over time Marantz, like most different larger-scale producers, switched from “analog” amplification to chip-based circuitry—however that launched its personal complications.
We wish you to listen to that inherent heat character in recorded music with out overdoing it so it’s dripping with syrup, which isn’t enjoyable.

“Ideally amplifiers would simply use an influence provide to make a facsimile of the incoming audio sign however greater, proper?” Dayton asks rhetorically. “Sadly with chip-based amplifiers there are issues. One, they’re normally unable to answer voltage adjustments in a short time, and that introduces distortion.” There are different points, however Dayton explains this led to Marantz’s resolution to construct their very own customized Hyper Dynamic Amplifier Modules (HDAMs). These are customized tuned by Marantz engineers, are comprised of particular person resistors, capacitors, and inductors, and permit Marantz to proceed with its signature “hotter” sound, with out shedding accuracy.
“Folks suppose that there are competing targets; which you could’t have crispness with out a form of cooler temperature. But it surely’s not true. We wish you to listen to that inherent heat character in recorded music with out overdoing it so it’s dripping with syrup, which isn’t enjoyable.”
The ultimate piece of the puzzle is easy design. Going all the way in which again to 1960, when Marantz got here out with the Mannequin 9 amplifier, a chunky block of steel that collectors nonetheless chase, the corporate has used a signature, middle “porthole” on the face of their amps that’s like a cyclops eye. Dayton says that on the Stereo 70s, as with previous items, it’s meant to convey data merely (reminiscent of displaying you that you simply’re streaming over AirPlay), quite than to introduce distraction with dancing lights. That is very true if you wish to use the unit with a minimal soundbar in entrance of a TV, the place shifting meters can be a visible hassle. That is additionally why the unit is slim—solely 4.1 inches tall—so it could actually match into your life quite than dominate a bookshelf.
There are some delicate however beautiful design parts to the piece, nevertheless. Easily surfaced dials for treble and bass, as nicely quantity, steadiness, audio system and enter supply grace the facade face plate, whereas that sits in opposition to a barely concave, Fibonacci patterned, dimpled metallic floor. “That’s meant to recommend some order in our universe,” Dayton explains. “Consider concentric circles fashioned from rain on a pond.” However, he provides, the thought is supposed extra to convey timelessly traditional minimalism. “At its basic degree this isn’t a scientific instrument. It’s there to assist talk artwork.”
The Marantz Stereo 70s is $1000 direct from the model or at choose retailers.
