It is basically a Yamaha RX-V6A with a detachable power cord LOL
There are however the usual Aventage chassis modifications such as the wedge (fifth foot) and a metal front fascia.
Anti Resonance Technology Wedge
The Anti Resonance Technology (A.R.T.) Wedge is a fifth foot in the center of the chassis unit base. It dampens vibrations from the power transformer, power transistors and heat sinks, as well as vibrations that might be caused by the sound from the speakers — providing dynamic sound and focused, accurate reproduction.
Here's a link to the A2A on Yamaha's site:
A2A - 7.2 ch AVENTAGE with CINEMA DSP 3D, HDMI™ 7-in/1-out, Special A.R.T technology.

The A2 has a RRP of £849 which is £200 more than that suggested for the RX-V6A. Is a fifth foot and a detachable power cord worth an extra £200?
There have been some noticable downsides to owning one of the new Yamaha models that will be also apparent with this one. The new remote has no ability to directly select a source and you have to cycle through the sources if using the IR remote. The receivers will however still repond to discrete IR source commands sourced via older Yamaha remotes. Yamaha have for some unknown reason not added support for their iOS or Android control app and the new models only support the MusicCast app. THe MusicCast app lacks many of the features you could control with Yamaha's control app. I've no idea as to why Yamaha have gone in this direction, but neither the redign of the remote and the ommission of the control app support helps enhance a users experience while using these new models.
For anyone as yet not aware of it, you should be a little warry of claims that these new models are 4K/120fps compliant. There is an issue with the chipsets that have been utilised by Denon. Marantz and Yamaha that actually prevents these models from conveying uncompressed 4K/120:
It seems that the implementation of HDMI 2.1 in some of the most recently launched AV Receivers is problematic and not delivering the fully promised 4K 120Hz experience. Read the news.

Yamaha imply that they'll have a fix for this, but there's no guarantee of this!
