As of March 29th select Marantz and Denon amps are eligible for the Auro-3D firmware upgrade. Similar to Dolby Atmos and DTS:X, Auro-3D adds a layer of overhead audio to your listening area. The result is 3-dimensional sound that is designed to fully engulf you in the audio experience.

On the Marantz side, the SR7010 AV receiver and the AV7702mkII pre-processor are the two amps qualified for the new Auro-3D update. The Marantz SR7010 (MSRP: $2,199) is a 9.2 channel amp that also supports Dolby Atmos and DTS:X. Along with this you get all the bells and whistles including HDCP 2.2 for 4K video, bluetooth, WiFi, an array of inputs and outputs as well as support for a variety of HD audio formats. The Marantz AV7702mkII pre-processor (MSRP: $2,199) has 11.2ch XLR pre-outs and 13.2ch RCA pre-outs. Like the SR7010 it supports Dolby Atmos and DTS:X, has bluetooth  and WiFi, and includes HDCP 2.2 on all its inputs and outputs.

Marantz’s sister company Denon also has two receivers which are eligible for the Auro-3D update, the AVR-X4200W (MSRP: $1,499) and the AVR-X6200W (MSRP: $2,199). Both of these amps have HDCP 2.2 on all their HDMI inputs and can decode Dolby Atmos and DTS:X. The X4200W and the X6200W have a plethora of inputs and outputs and are pretty stout in the wireless department thanks to built-in bluetooth and WiFi.


The only downside is that the Auro-3D update isn’t free. If you decide to grab the upgrade you can expect it to cost you about $199.
