Marantz will roll out the first of its 8k capable AV receivers during August and September. The new SR-Series, comprising the SR5015 AV Receiver and the AV Amplifiers SR6015, SR7015 and SR8015 feature 8K HDMI support, along with a wide range of immersive audio compatibility.

The lineup consists of the seven channel SR5015, rated at 180W p/c, followed by the nine channel SR6015, at 185W which adds IMAX Enhanced certification to the Dolby Atmos and DTS:X baseline specification, and the nine channel 200W SR7015 which adds Auro 3D to the codec list.

Both the SR6015 and SR7015 also feature 11.2ch processing, utilised by adding a secondary stereo amplifier. Topping the line-up is the eleven channel SR8015, rated at 205W, with13.2 processing capability. The model also offers DTS:X Pro support, and high-end embellishments like a single board amplifier design, toroidal transformer and copper plated chassis.

DTS:X Pro allows for 7.2.6 or 9.2.4 speaker configurations. IMAX Enhanced films can play in 7.2.6 or 9.2.4 using 13.2 channel processing and additional external amplification. DTS:X Pro will land on the boxes via firmware update later this year.

In addition to DTS:X Pro, the 2020 SR-Series also offer Dolby Atmos Height Virtualization Technology and DTS Virtual:X. These height virtualization technologies provide immersive audio without physical height channels, creating virtual height effects in a 7.1, 5.1 or 2.1 speaker arrangement.

All models sport a single 8k enabled HDMI input which supports both 8K/60Hz and 4K/120Hz, while a new HDMI feature called Quick Media Switching (QMS) allows a source to instantly switch frame rate to eliminate screen blackout. HDR10, HLG (Hybrid Log Gamma) and Dolby Vision, as well as 4:4:4 Pure Color subsampling and BT.2020 pass-through are standard.

Serious gamers will appreciate compatibility with Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM) and Quick Frame Transport (QFT). There’s also support for eARC (Enhanced Audio Return Channel).

Additional connectivity includes a turntable phono input, plus front-panel USB port that offers audio file playback (including WAV, FLAC, ALAC and DSD 2.8/5.6 MHz files).

As we’d expect of Marantz, all the models boast the brand’s proprietary Hyper Dynamic Amplification Module (HDAM) circuitry. With low impedance driver capability, the SR-Series can be partnered with a wide range of speakers.

There’s also a new pre-amplifier mode on the SR6015, SR7015 and SR8015 models, which provides a clear signal path and more tolerance in clipping levels by disconnecting internal amplifiers when the receiver is used as an AV processor, and all speakers are powered by external amplifiers.

Multiroom high-res audio streaming support comes via HEOS Built-in. The 2020 SR-Series can decode up to 24-bit/192-kHz ALAC, FLAC and WAV lossless files as well as DSD 2.8MHz and 5.6MHz tracks.

Installation and room calibration comes via Audyssey MultEQ XT on the SR5015 and MultEQ XT32 on the SR6015, SR7015 and SR8015 models. The latter is adding Low Frequency Containment, for more precise deep bass control. There’s also a Dual Speaker Preset Memory, which enables users to toggle between two calibrated speaker configurations, which can be switched on the fly.

Marantz SR-Series AVRs are also Roon Tested certified. Marantz Roon Tested AVRs can be found and setup by Roon via AirPlay 2 or hardwired into a Roon Core device.

The SR5015. SR6015, SR7015 and SR8015 will retail for £899, £1,149, £1,599 and £2,799 respectively. The SR7015 is available in Aug, the rest follow in September.
