HEOS & Atmos in slimline AVRs

As several Sound+Image awards attest, we’ve maintained a high regard for what Marantz calls its “slimline” series of AV receivers, though really they’re short, rather than slim, but we guess the “short-arse” series wouldn’t sound so marketable.

The latest models aim to maintain the excellent performance of previous models, but bring a number of impressive additions — HEOS multiroom integration, and Dolby Vision HDR compatibility (in addition to full 4K/UHD abilities) in both new models.

The $1299 NR1608 is just 10.5cm tall, yet includes seven 90W channels of amplification, has decoders for both Dolby Atmos and DTS:X surround sound, and an impressive eight HDMI inputs compatible with 4K up to 60Hz with HDR10, Dolby Vision and Hybrid Log Gamma (this last via future firmware update). The seven channels can be configured to deliver a proper 5.1.2-channel Atmos soundfield, while still compatible with Dolby TrueHD and DTS-HD soundtracks for conventional 5.1- or 7.1-channel surround. Audyssey MultEQ simplifies pinpoint-accurate set-up and calibration, while the optional Audyssey MultEQ Editor App can be used to further refine the set-up or tune it. The NR1608 also streams music from local network storage or the internet using either wired or Wi-Fi networking. As well as Internet radio and services including Deezer, Spotify Connect and Tidal, it can stream from computer or NAS drive at up to 192kHz/24- bit and DSD5.6MHz, while direct streaming options include Bluetooth and AirPlay.

HEOS integration can be accessed directly from within the Marantz 2016 AVR Remote app (giving complete control of the receiver), allowing streaming around the house to other HEOS-equipped products.

The $999 NR1508 is a simpler unit but still promises extensive home entertainment options through the same HEOS integration, while its receiver abilities on this 5.2-channel design include five discrete 85W channels, compatibility with all the same 4K video formats as the NR1608, with six HDMI inputs and decoding for Dolby True HD and DTS-HD for conventional surround set-ups. Audyssey MultEQ basic set-up and calibration is featured, and the NR1508 can also be controlled using the Marantz 2016 AVR app.

Network and wireless music streaming includes Ethernet/Wi-Fi capability including access to internet radio, streaming services, and locally stored content at up to 192kHz/24bit and DSD5.6MHz. In addition, the NR1508 features HEOS wireless multiroom audio integration, allowing it to become part of a complete whole-house music system all controlled by the HEOS app. Direct streaming is again available via Bluetooth or AirPPlay.

Should you have the space, of course, Marantz is also rolling out its full-sized 2017/8 models. More information:
