About The Marantz Model 30 Stereo Amplifier

The Marantz Model 30 integrated amplifier is a fully discrete, dual mono, two-stage design that marries custom (Hyper-Dynamic Amplifier) HDAM-SA3 modules in a feedback-free pre/driver stage to a pair of Class D amplifier modules (Hypex NC500 OEM) on the output stage for 100 Watts per channel into 8 Ohms, and 200wpc into 4 Ohms. Marantz’s HDAM technology was developed in 1992 as an improvement over Op-Amp-based circuits. A rather large toroidal transformer sits inside the Model 30 to supply the preamp and phono amp stages, which helps account for the Model 30’s almost 15 kilogram heft, while the power amplifier stage is fed from its own switch-mode power supply.

The Model 30 offers a wealth of analogue connection possibilities with the discrete phono stage’s RCA inputs sitting below the line-level RCA inputs labelled CD, Tuner, Line 1, Line 2 & Recorder. There’s a fixed volume Record Out, which could also be used to feed an external headphone amplifier, and also a variable volume Pre Out which can be used with an external power amplifier or a subwoofer or two. A welcome feature is a Stereo Power Amplifier Input for use with an external stereo or home theatre preamp. A single pair of hefty high-purity nickel-plated speaker binding posts, remote control input, and IEC inlet complete the rear panel. If you’re looking for a matching DAC, CD player and/or streaming device, the Marantz SACD 30n Streaming CD Player is the natural choice.

The front panel is central to the Model 30’s good looks: a backlit raised matte section that allows light to peek out either side onto a wavy textured backplate, which looks a bit like carbon fibre from a distance. This lighting effect can be dimmed or turned off using the included remote. The classic Marantz “Porthole” display sits dead centre on the raised section and is joined by six control knobs for input selection, phono input selection – MM, MC Low (33 Ohm), MC Mid (100 Ohm) and MC High (390 Ohm), bass/treble (which can be bypassed using the remote), balance and volume. The power button and 1/4” headphone jack reside on either side of the faux carbon fibre backplate.

The remote is more than full function as it can also control the matching Marantz SACD 30n Streaming CD Player while also performing all of the front panel functions plus mute and dimmer for the subtle but pleasing front panel lighting effect.

Tuned By A Marantz Sound Master: “Making sound the Marantz way is a seamless fusion of art and science, practiced by artisanal creators who balance and select components individually for their sonic qualities – they are the Sound Masters, the magicians.”

In the case of the Model 30, we are talking about Yoshinori Ogata who follows in the footsteps of Saul Marantz, Ken Ishiwata, and Ryuichi Sawada. This is the audiophile ideal, as it speaks to the notion that hi-fi products are voiced by ear as opposed to rigidly following some measured ideal.

Designed To Last: You see and feel it in the build quality and you hear it every time. No matter your musical passions, your music always sounds better with Model 30.

Tuned With Passion: Hundreds of hours of thoughtful Sound Master tuning ensure the exquisite detail and musicality Marantz always delivers.

Fully Discrete & Accurate Detailing: Marantz HDAM-SA3 technology is comprised of dozens of independent parts, each hand-selected for pure, detailed Marantz sound.

Extraordinary Sensitivity: Designed to replicate the sensitivity and feel of a vintage analogue amplifier even when simply adjusting the volume.

Exquisite Sound Tuning: Model 30 continues the renowned heritage of exquisite Marantz amplifiers. Tuned by the Marantz Sound Master who channelled his passion, experience, and extraordinary ear into the amplifier design.

The Most Musical, Accurate, Detailed Sound: Model 30 is built on its own discrete circuit board, the Hyper-Dynamic Amplifier Module, or HDAM. By custom-curating hundreds of individual parts, rather than adopting an off-the-shelf solution, the Model 30 HDAM significantly outperforms standard integrated circuits to create the unique musicality you always expect from Marantz.

Marantz Musical Premium Phono EQ: Envisioned to deliver optimal sound quality by simplifying the signal path – vital given the delicate nature of phono signals – the Phono EQ stage in Model 30 can be used with both moving magnet and low-output moving coil cartridges, thanks to a built-in MC head amplifier.

The design lowers distortion, which is why the phono stage uses two-stage amplification, combining Marantz HDAMs with JFETs in the input stage, giving high input impedance. This allows the non-negative-feedback design to be further simplified by the deletion of coupling capacitors, again reducing distortion and enhancing signal purity.

MC / MM Phono Input Impedance Selector: In order to optimize sound performance when using a moving coil (MC) or magnetic moving (MM) cartridge, and to accommodate all configurations as much as possible, Model 30 is equipped with an input impedance selector. The input impedance can be adjusted to three different settings: MC LOW (33 ohm), MC MID (100 ohm) and MC HIGH (390 ohm).

Custom Volume Control: Newly developed electric volume control uses the latest volume control IC to realize better channel separation, dynamic range and distortion-reduction. Model 30 employs a new Marantz-designed electric volume control for high linearity and best-in-class channel separation. In other words, you always get the volume precisely how you want it.

In A Silent Way: The advanced headphone circuit delivers superb audio fidelity with the widest range of headphone types and impedances, including low impedance headphones. So when you want to hear everything but leave the rest of the house in blissful silence, you’ve got it.

Built For Generations: Like its counterpart, the SACD 30n Streaming CD Player, the Model 30 Integrated Amplifier is designed to the highest standards. The solid chassis is constructed from thick, heavy, non-magnetic aluminium panels and a rigid steel top cover to eliminate added interference. Sturdy, brass machined independent input terminals for CD and Phono plus Marantz original high-quality/high-purity nickel-plated speaker terminals ensure the best signal possible.

About Marantz

It all began in the 1950's with a man - a technician named Saul Marantz. More than any other person, Saul Marantz defined premium home entertainment. Driven by his passion for music and his accomplishments as a classical guitarist – accomplishments that led to a close friendship with Andres Segovia – he was never satisfied with the “hi fi” equipment of his day. So he built better; first in his basement, later in a factory. His talent for industrial design and his ability to infuse talented engineers all insured that his company would remain a premiere name in the industry he helped establish.

The team at Marantz continues to be passionate about music and the products they manufacture - a history spanning close to 70 years. With their receivers, amplifiers, CD players, turntables, and other components, they strive to reproduce the magic of the original performance — just as the artist intended. And the parent company has solid commercial backing so you can have confidence they are around for the long haul. Marantz has one simple philosophy and slogan: "because music matters." If you can relate to this ethic, then you're almost home!

Our Take On The Marantz Model 30 Stereo Amplifier

Finally, a Marantz product that doesn’t look exactly the same as every other model they’ve produced for the last 20 years or more. The Model 30 brings a refreshing visual change to the Marantz lineup as well as offering some new technology to boot. The use of proprietary Marantz Hyper-Dynamic Amplifier (HDAM) modules with Hypex NC500 Class D amplifier modules results in a neutral sonic character that will play well with almost any brand of speaker. What’s more, the Model 30 puts out a solid 100 Watts into 8 Ohms and then, surprisingly, doubles that to a rock solid 200 Watts into 4 Ohms which means nothing’s going to phase this amplifier no matter what you throw at it. Marantz has chosen to make this an all analogue affair, no ‘let’s include the kitchen sink’ built-in DAC here, which we think is a good thing. Do one thing, and do it right. If you need all that digital stuff then look no further than the matching Marantz SACD 30n which includes the ‘kitchen sink’ and a few other digital niceties you may not have been expecting.
