Internal pictures of Devialet OdA from Hong Kong High End 2016

[Confused]

This must be a upgraded OdA to D1000 or am I wrong here?

He says in the video that it is the V6 board, so it's the innards of a Pro.  The case behind is black chrome, so I'd say it's the Pro.  I see your point though, there is lots of gold inside, so the innards do look a bit O'dA.

I have not seen the backside of a D1000PRO do that also have a copper coloured plate were the connectors are?

The 1000 Pro has a solid copper base.  The rear connector plate certainly looks like copper, although here I am assuming it is solid copper, but it could possibly be copper plate.  But copper coloured, yes, definitely.
