Marantz SR7015 Review • AV-receiver with every possible modern feature

Marantz SR7015

Marantz SR7015 is located approximately in the middle of the corresponding model range of this company and is equipped with technologies that are called “to the eyeballs”. It is a 9-channel AV amplifier that supports Dolby Atmos, DTS: X and Auro-3D (up to 11.2 channels processing) and is IMAX Enhanced certified. It also features advanced eARC technology and delivers high dynamic range video: HDR10, HLG, HDR10 + and Dolby Vision. For PC gamers, it offers 4K / 120Hz pass-through, VRR, ALLM and QFT support. But perhaps the biggest innovation for this model is the availability of an HDMI input and two HDMI outputs that support 8K / 60Hz video.

Other features of the Marantz SR7015 include HEOS multi-room system, support for audio up to 24-bit / 192 kHz, AirPlay 2, Roon technology and voice assistants: Amazon Alexa, Siri and Google Assistant.


The Marantz SR7015 has a classic design for this class of models with matte curved sides of the metal front panel and its shiny center. On the left side is the input selection knob, and on the right is the volume control. Between them is an attractive circular display with blue backlighting that can be turned off if desired. The information shown on the display is minimal, but it looks cool and allows you to immediately identify the SR7015 as a Marantz model.

The fact that the small round display shows a minimum of information is not significant for two reasons: firstly, the device has excellent on-screen menus, and secondly, a larger and more informative display is hidden behind a hinged cover. There you will also find a set of basic controls and a few additional inputs including HDMI and USB; along with a headphone jack, composite video, analog stereo, and an auto-calibration microphone input. The build quality of the Marantz SR7015 is very good and it looks solid and expensive. The AV amplifier measures 440 x 185 x 411 mm (W x H x D), weighs 14.2 kg and is available in black or silver-gold exterior finishes.

Connections and management

The Marantz SR7015 is equipped with an impressive array of inputs, which, however, can be considered redundant. A lot of outdated inputs look a little strange, for example, component and composite video, and there could be fewer analog and digital audio inputs. On the other hand, there is an input for an MM-pickup, which is sure to please the owners of turntables. The AV amplifier has eight HDMI inputs (seven at the rear and one at the front) and three HDMI outputs. One of the HDMI inputs and two HDMI outputs support 8K / 60Hz and 4K / 120Hz video (up to 40Gbps), and the main HDMI output also supports eARC (Extended Audio Return Channel).

All HDMI connections support HDCP 2.3 and can transfer 4K / 60p video with support for 3D, BT.2020, HDR10, HLG, HDR10 + and Dolby Vision, ALLM (Auto Low Latency), VRR (Variable Refresh Rate) , QMS (Fast Media Switching) and QFT (Fast Frame Transfer). In addition, HDMI inputs are automatically renamed according to information provided by the source (if available).

As impressive as it all sounds, it would be nice if the Marantz SR7015 had two HDMI inputs supporting 8K / 60Hz and 4K / 120Hz, because some people might buy two of these. However, you can connect one 8K source directly to the display and send lossless audio back through eARC.

Other connections include a LAN port, two 12V trigger connectors, an IR input and an external control RS232 port; as well as two antennas for Wi-Fi and Bluetooth. There is 7.1 channel input as well as processor outputs for all eleven channels in case you decide to use external amplifiers. The SR7015 has outputs for two subwoofers. However, there are no built-in tuners in this model, so the SR7015 is an AV amplifier, not an AV receiver. Although there are only nine built-in power amplifiers, this unit is equipped with 11 pairs of color-coded speaker connections in a row. These are high quality screw terminals that fit banana plugs or simply stripped speaker cable ends.

The SR7015 comes with a standard Marantz remote in a matte black / silver finish. It is well thought out, the buttons are conveniently located and, overall, quite comfortable to use. The remote even has a backlight to control the AV amplifier in a darkened room.

Features and characteristics

The Marantz SR7015 uses nine discrete high current power amplifiers delivering an equal output of 200 watts. The AV amplifier can operate with low impedance acoustics, which makes it sound more balanced. The SR7015 is equipped with patented HDAM (Hyper Dynamic Amplifier Modules), current feedback technology and advanced AKM AK4458 32-bit D / A converters on all channels. All of this is needed to ensure optimal fidelity, wider dynamic range and reduced distortion.

The amplifier decodes high-resolution audio in ALAC, FLAC and WAV formats up to 24-bit / 192 kHz, as well as DSD 2.8 MHz and 5.6 MHz, but analog lovers can connect their turntable to the Marantz SR7015 amplifier. This model has support for Dolby Atmos, DTS: X and Auro-3D, as well as IMAX Enhanced DTS: X. Although there are only nine built-in amplifiers, processing is done for 11.2 channels, so if you add an external power amplifier to the SR7015 you can assemble a complete 7.2.4 channel system. External antennas ensure stable Bluetooth and Wi-Fi streaming even in challenging urban environments (Wi-Fi supports 2.4GHz (11b / g / n), 5GHz (11a / n). In addition, the SR7015 has the ability to AirPlay connection of Apple devices 2.

HEOS multiroom technology not only provides a convenient control app, but also provides access to various music services: Spotify, Tidal, Amazon Prime Music, TuneIn, Soundcloud, Pandora, Napster, Deezer, iHeartRadio, Rhapsody and SiriusXM. The SR7015 works with Amazon Alexa and Google Assistant voice assistants, as well as Siri thanks to AirPlay 2. As a result, you can “ask” the unit to play your favorite music, turn up the volume, skip to the next track, switch inputs, and more.

Other features include a pre-amp mode to turn the SR7015 into an AV processor, the Marantz AVR mobile app, smart features and a prompt system for easy setup and use. There is also the possibility of connecting to a smart TV and building an audio system for multiple zones. The SR7015 is Roon Certified to help you get the most out of your digital music library, while also supporting external RS232 and IP control, and is Control4 compatible.

The Marantz SR7015 features Audyssey MultEQ XT32 Automatic Surround Calibration, including Audyssey LFC (Low Frequency Conservation), Audyssey Dynamic Volume and Audyssey Dynamic EQ. This model also features Audyssey Sub EQ HT mode for precise matching of two subwoofers, as well as the ability to store two Audyssey settings. Finally, there is the optional Audyssey MultEQ Editor application for the most detailed and precise audio adjustments.

Setting it up

Setting up the Marantz SR7015 for the first time is pretty easy, thanks to the Setup Assistant, which guides you through the entire process step by step. The Setup Assistant offers simple, clear and concise instructions with a straightforward graphical user interface, which as a result helps make Marantz much less intimidating for those who are not yet familiar with multichannel AV amplifiers. The Setup Assistant covers everything from choosing speaker layouts to setting up various inputs and outputs and various additional functions. It even verifies the correct speaker connection phase and the set volume of the subwoofer (s) before running Audyssey MultEQ XT32 Auto Calibration.

The SR7015 comes with a measurement microphone, and MultEQ XT32 can analyze the sound of each speaker (including subwoofers) at 8 points and then optimize each channel to get the right overall surround sound. If you don’t have a tripod for a setup mic, Marantz even includes a cardboard stand to accommodate it.

When testing, I started with a basic two-channel system, before moving on to a 5.1-channel configuration, and then to 7.1-channel. I then tested the SR7015’s surround sound capabilities in Dolby Atmos, DTS: X, Auro-3D, and IMAX Enhanced DTS: X

I started with a 5.1.4 configuration before moving on to a 7.1.2 system, and then finally added two more external amplification channels and ran a complete 7.2.4 system with three front channels, two side channels, two rear channels, two subwoofers and four high-altitude channels. I used a variety of content, including 5.1 movies and music, 7.1 movies and 3D soundtracks. I used CDs, SACDs, DVD-Audio, Blu-ray and Ultra HD Blu-ray discs, as well as High resolution audio files and various streaming services, including Tidal, as the main content when testing the Marantz SR7015.

Marantz SR7015: Sound quality

The Marantz SR7015 delivers great sound whether it is dual or multi-channel or plays 3D audio. What is immediately impressive about it is the significant headroom, which ensures confident sound even when all channels are actively used. The result is a wide dynamic range and rich, sweeping sound, without feeling like the Marantz SR7015 is about to run out of steam, even in the most challenging scenes. And for all that power, the amp’s sound is fast and agile, with accurate transient response and complete acoustics control.

Marantz is known for making AV receivers and amplifiers more musical than most competitors, and the SR7015 is no exception. It plays 2-channel music very well, and The Waterboys’ Good Luck, Seeker sounds open and detailed. Vocals are conveyed accurately, guitars maintain drive, and drums sound dynamic and energetic. The AV amplifier does a great job with both 5.1 and 7.1 soundtracks, creating an open and convincing soundstage. Music and effects are properly distributed across the three front channels, the backstage is engaging, and dialogue remains centered on the screen, keeping it intelligible, clear and crisp.

The distribution of special effects throughout the room is surprisingly even, with accurate tonality and a seamless surround sound space that literally envelops the audience. Bass is also conveyed well, low frequencies are well integrated into the rest of the range, creating an excellent foundation for the overall sound.

The SR7015 plays multichannel tracks very well. As sound images move around the room, they remain crisp and focused at any point in space, allowing them to be precisely located. At the same time, their movement from speaker to speaker is smooth, which creates a complete feeling of being surrounded by sound.

When it comes to Dolby Atmos, the sound quality of the Marantz SR7015 is just as impressive, with excellent rendering of effects in a surround soundstage. The opening race from Ready Player One is almost entirely special effects, and everything from the roar of a Tyrannosaurus rex to the bangs in the chest of King Kong to the flying DeLorean seamlessly blends into a single soundscape, fully engaging you in the action on screen.

The SR7015 is also an excellent performer when it comes to DTS: X, creating a hemisphere of sound in which effects are precisely moved. The Jurassic Park movie boasts a stunning new DTS: X soundtrack that impresses with its heavy bass, deafening roar of giant reptiles and heavy downpour during the famous T-Rex attack.

There are still very few discs with Auro-3D sound, and the speaker configuration for it does not correspond to Atmos or DTS: X, but if this is important to you, the SR7015 can reproduce records in this format perfectly. The Pixels cartoon sounded great, especially in the episode “Caterpillar” where the effects were placed on top and the attackers circled the room.

The Bad Boys for Life movie disc boasts the IMAX Enhanced DTS: X soundtrack, which Marantz correctly recognized and decoded perfectly. The soundstage is as bombastic as the film, with an abundance of funky music and sonic chaos in the climactic shootout. Shots are heard overhead, ricochets echo down the walls, and shards of broken glass are falling from the ceiling.

Marantz SR7015 is an impressive AV amplifier that seems to have every possible modern feature. In fact, besides the lack of an FM/DAB tuner, it is difficult to blame it for the lack of anything substantial.

Marantz SR7015 is an impressive AV amplifier that seems to have every possible modern feature. In fact, besides the lack of an FM / DAB tuner, it is difficult to blame it for the lack of anything substantial. There are a variety of entrances and it has a signature Marantz design as well as superb build quality. Perhaps more importantly, the SR7015 sounds fantastic, precise and musical, as we’ve come to expect from Marantz. The nine amplification channels have significant headroom, and the surround sound impresses with its precise effects. Overall, the AV amplifier has consistency, power, and confident acoustics control.

The SR7015-based system can be further expanded to 7.2.4 by adding an external two-channel power amplifier. Among the shortcomings of this model, we can only note one HDMI 8K / 60 Hz input, and a slightly higher price than its closest competitors. Otherwise, this is our highly recommended AV amplifier.
