you are very fortunate. But it is not everybody’s situation.
In my opinion, the ACT4 should come with a ´´ auto room correction’´,included at his price ( or a bit more $ )There are so many situations that can occure for this function to be important : Speakers changes ;furnitures changes in the listening room; systeme moved , etc.
You can not call your dealer (integrater ) every time , you make a change.
ACT4 does not come with ´´ Auro 3D ´´
I hope It will come in a futur firmware or hardware upgrade .
For my personnel situation , I would rather have a second balanced
analog input (XLR) than ´´ multi input ´´ rca .
I have received, very good services and support from Indy Audio Labs, for the recent firmware upgrade : V02.197( 20 channels model)
There is still some minor issues that , I hope , will be solved in a near
Like you , I have bought this unit without previous listening.
I took a chance. I will wait ,the future upgrades , to make a final
60% music 40% video
And I am glad , you enjoy your unit.
