SR7015 Model DTS X AV Amplifier by Marantz – Review

Offering a powerful 9-channel amplifier, with 125 watts per channel, the Marantz SR7015 consistently has the strength to make an impression. For 3D Atmos/DTS:X sound you can select between 7.2.2 or 5.2.4 speaker options with 2 or 4 ceiling speakers. Additionally, stick with 5.2.2 and power a second pair of speakers in another room or bi-amp your primary pair of speakers. As your system expands, so the capabilities of this Marantz AVA grows with it.

Enhance to 11-channel sound for cinematic immersion
Add an additional stereo power amplifier for next level surround sound. Maintain 4 ceiling or Atmos-enabled audio speakers as well as full, 7-channel surround sound. As an alternative, use 2 Atmos speakers and take pleasure in a wide-ranging soundstage with ‘front wide speakers’ forming a 9.2.2 system. If you don’t luxury a Dolby Atmos specific system, but want the most impressive sound possible, go for an 11.2 configuration. This provides 7.2 sound with the addition of front width and front height speakers.

The front fascia of the SR7015 showcases Marantz’s signature ‘porthole,’ a design element synonymous with the brand. The overall aesthetic is marked by a simple, uncluttered elegance, with controls discreetly tucked behind a pull-down door. The matte black finish accentuates the source and volume dials, as well as the power button, which are the only visible controls. Opening the pull-down door reveals access to extensive setup menus, along with a composite video input, USB input, HDMI input (4K/HDCP 2.3), headphone input, Audyssey mic input, and a large LCD display. While the porthole display is visually appealing, its size poses a challenge for readability at a distance, prompting users to weigh form against function.

On the rear panel, the SR7015 boasts seven assignable HDMI inputs and three HDMI outputs, featuring eARC support on the main output. With the ability to decode 11.2 channels, its pre-outs can expand capabilities and enable external power amplification for existing channels. Legacy connections include composite and component video inputs and outputs, analog inputs and outputs, and coaxial and optical inputs. Additional features encompass dual independent subwoofer outputs, 12-volt triggers, IR input, RS-232 input, and Ethernet. Wi-Fi and Bluetooth support, facilitated by included antennae, complement the thirteen gold-plated speaker binding posts.

Maintaining Marantz’s commitment to quality, the SR7015 incorporates proprietary HDAM circuit boards and discrete power amplifiers across all channels. The claimed power rating is 125 watts (8 ohms, 20Hz–20kHz, 0.05% two channels driven), with a 70% power guarantee, translating to approximately 84W with all channels active—an honest acknowledgment in an era where power figures are often exaggerated.

The SR7015 supports various multichannel formats, including DTS HD Master/X, Dolby Surround/True HD/Atmos, Auro 3D, and more via firmware updates. HDCP 2.3-compliant HDMI inputs accommodate 4K and 8K video at up to 120 and 60 frames per second, respectively. Notable features include eARC, CEC, Dolby Vision, HDR10+, Dynamic HDR, HLG, ALLM, VRR, QFT, and QMS—ideal for gaming enthusiasts.

Equipped with Audyssey XT32 room correction software, the SR7015 includes features like LFC, Sub EQ, Dynamic Volume, and Dynamic EQ. Despite Audyssey’s age, recent updates align it more closely with contemporary room correction systems.

Networking options encompass HEOS Multi-Room, Alexa, Google Voice Assist, Apple Home Pod, Internet Radio, and support for streaming services such as Spotify, Amazon Music HD, Deezer, Tidal, and Napster. The SR7015 accommodates both lossy and lossless audio formats, including MP3, WMA, FLAC HD 192/24, WAV 192/24, and ALAC 192/24.

Unique Marantz audio technology
Even though feature-packed, the continue to puts sound top quality first. This Marantz uses a discrete, high-current amplifier with Marantz’s own amp modules – HDAM. These op-amps use surface-mount metal-film resistors for higher temperature balance. The final result is a clearer, much less distorted sound, whatever the volume. Some other audio improvements include AKM AK4458 32-bit DACs and a Hybrid PLL Clock Jitter Reducer for a more precise, vibrant sound.Marantz SR7015Four, 3D sound formats, including Dolby Atmos, DTS:X, IMAX Enhanced and Auro-3D
