More news from the annual Denon & Marantz product showcase comes in the form of new home cinema amplifiers from Marantz. Seven in total, prices start at £449 and go right up to £3349.
All seven-channel and above amplifiers support Dolby Atmos and DTS:X (with an upgrade), while some top-end models will also support Auro 3D. HDCP 2.2 and HDMI 2.0a are on board ensuring the AV amps are ready for 4K Ultra HD video.
Elsewhere there's a continued focus on stereo and multi-channel music performance, a new remote app and set up assistant, plus "class-leading" support for 3rd party control for the custom install market.
First up are two new slim network AV receivers, the NR1506 and NR1606. Both are due in August and will cost £449 and £559 respectively.
The amps feature WiFi, AirPlay, Bluetooth and Spotify Connect, plus gapless HD audio, DSD and AIFF music streaming. There's also an Apple-compatible USB input on the front.
Both feature a "retuned sound", plus the updates to the app and set up process.
