Hello everyone from Rome :-)
I write because I need the experts of this wonderful brand!

I have a full system with Arc + Sub(Gen3) + One, I only watch movies with 4K discs and Playstation 5.
I would like to understand if the addition of the Era300 gives me something more about the Atmos, given that the Arc itself already has speakers that go upwards for the Atmos effect.
Does buying the Era300 increase the atmos effect? So I would have the Arc + Era300 atmos speakers?

Thanks to everyone for the precious advices!
