Marantz stands at the forefront of the global audio and hi-fi industry, renowned for its cutting-edge audio innovations and exceptionally clear sound reproduction. Founded in 1953 by Saul B. Marantz in the United States, the company has become a benchmark for audio excellence across the globe.

A signature feature of Marantz products is the use of HDAM (Hyper Dynamic Amplifier Module) technology—a proprietary design that delivers ultra-wide bandwidth, low noise levels, and high-speed signal processing. These modules are a cornerstone of Marantz’s reputation, ensuring superior audio precision and depth across the sound spectrum.

Now, let’s take a closer look at the SR8012, one of the brand’s most advanced home cinema amplifiers, built for audiophiles and home theater enthusiasts seeking high-end performance.

The SR8012 home theatre amplifier has 11 stages, each capable of delivering 205 watts of output power when driving one channel, and outputing 175 watts when driving two channels.

On the front of the device there is a circular, small display and two large dials, one for volume control and the other for input selection. Hidden behind a hinged cover under the display hides a much larger display where other controls and sockets are located.

Inside the housing, a large toroidal transformer and two heatsinks, also of considerable size, ensure stable performance. Using a Hyper Dynamic Amplifier, or HDAM circuitry, detailed sound and extended bandwidth are also guaranteed with this amplifier. The amplifier was manufactured using high quality components that received a base plate copper coating. Teflon tape is used in the circuit for better attenuation.

The appearance of the SR8012 amplifier is almost identical to the design of its predecessor, the SR7012. What sets it apart from the previous model is that this amplifier lacks the AM / FM tuner needed for analog radio, but has a couple of RCA connectors.

With a network internet connection and the built-in Tuneln internet radio, you can listen to the radio.

On the back there are 8 HDMI inputs, 3 HDMI outputs, all of which are UHD compatible and HDCP 2.2 compliant, allowing you to connect a number of 4K source devices. The HDMI output has ARC support, but after an upgrade we can even make it eARC compatible. The Marantz amplifier also has 7 additional stereo inputs and one Phono (MM) input, as well as 7.1 multi-channel inputs.

The Marantz SR8012 is fully equipped for seamless integration into any advanced home theater system. It features four composite and three component analog video inputs, as well as an RS232C port and a LAN socket, making it ideal for Creston Connected environments. The amplifier supports both wired (LAN) and wireless (Wi-Fi) networking, offering flexible connectivity options for any setup.

The HEOS multiroom system allows the amplifier to serve two additional rooms in addition to the main zone. In fact, the analog output signals are routed to the other two zones by the amplifier, making it a central part of the system. The HEOS application is easy and fast to download.

As usual with previous models of Marantz amplifiers, the SR8012 also has an integrated Audyssey Multieq XT32 room calibration program that measures and makes the necessary settings together with the included microphone, moreover, the two subwoofers can be measured and adjusted separately.

The Marantz SR8012 comes equipped with powerful DSP features, including Audyssey Dynamic Volume and Audyssey Dynamic EQ, both of which significantly enhance the listening experience. These technologies help maintain consistent volume levels and dynamic clarity across all content types, whether you’re watching movies or listening to music.

During our test, the Audyssey EQ calibration program delivered far better and more accurate results than in previous experiences. The system performed its automatic room measurements and adjustments flawlessly, providing a balanced and immersive sound profile. While the crossover settings required minor manual fine-tuning, this was only to achieve a more refined and personalized final result—a testament to the precision and flexibility of the SR8012’s calibration tools.

The amplifier, also known as “2ch Playback”, also has a manual adjustment option, which allows you to select a separate speaker setting, two-channel direct or stereo mode. IMAX Enhanced support has also been updated. External antennas are included with WiFi and Bluetooth. Amazon Alexa, Google Assistant, and Siri voice controls are also available through the amplifier, and the MultiEQ Editor controls room sound optimisation and setting the maximum filter frequency. New calibration features can also be found in other devices such as Sub Level Control, which controls the subwoofer level, Dialogue Level Adjust, centre channel adjustment and Bass Sync.

The testing

We tested the amplifier in a medium-sized living room, where we connected the Marantz amplifier to a pair of Dali Epicon 8 speakers and an SVS subwoofer.

There is still room for improvement in the acoustics of the living room, so far only a few walls had sound-absorbing acoustic panels, but this is not enough for perfect sound conditions.

We first started the tests with a movie. We sat down in front of the 2015 vintage mystical thriller Solace, starring Anthony Hopkins and Colin Farrell, among others. The atmosphere of the exciting and mysterious story was only further enhanced by the amplifier. Thanks to the combination of excellent speakers and amplifier, we heard clear, powerful and detailed sound. Sophistication and neutrality were the most obvious characteristics of the amplifier, it produced a realistic and reasonable stage image, in which dynamics were definite, dialogues well understood, and it provided a spacious and airy sound.

We also wanted to put the amplifier performance to test from a musical standpoint. We listened to Dua Lipa’s song We’re Good. The stereo sound was excellent, although it could not surpass the stereo sound production of a similar category stereo amplifier. We experienced strong upper and middle ranges, and clarity and distortion-free sounds were maintained even at high volumes. The amplifier was able to deliver sound dynamism even at lower signal levels, and we witnessed definite, intense depths and spaciousness while listening to music as well.

What Is a Multiroom Sound System?

A Multiroom (or multi-room) sound system consists of several interconnected audio units, often located in different rooms, that can operate independently or be synchronized to play the same audio throughout the home. One unit typically acts as the central controller, allowing you to enjoy seamless playback in multiple areas without moving speakers or equipment from room to room.

Most Multiroom systems are wirelessly controlled, usually via smartphones or tablets, offering easy, intuitive management of music and volume in each zone.

A complete Multiroom setup may include:

• Speakers
• Subwoofers
• Amplifiers
• Wireless streaming components

Thanks to wireless connectivity, these systems are cost-effective, easy to install, and eliminate the need for complex cabling. Most are also modular and expandable, allowing you to add more zones over time as your needs evolve.

An excellent example of this technology is the HEOS Multiroom system, which is a built-in feature of many modern amplifiers, offering state-of-the-art performance and flexibility for whole-home audio.
