The only upgrade was the ceiling speakers. I had 7.x before. Replaced my Qs8s with M22s for the surround locations. The Denon 3808ci was one of the kings back in the day. Initially I do thing ARC is much better than Audyssey Mult XT on my Denon. I did 7 measurements, one in each seat but can do up to 10. Might do another measurement and put the remaining 3 between the 2 rows, will see....
I don't think it is an issue where the sub needs to be dialed down they are all calibrated to have combined dB of 75dB. Last night I recalled I had removed the rubber feet. I have the horizontal EP600 but I actually stand it up in the back of the room. I thought it looked cleaner not having the feet sticking out so I removed them. But in doing so created 4 holes that I think air is escaping. Will do some more testing tonight...
