Thanks. The Denon S730H is on sale for $349 today. That seems like a pretty good price for it's feature set. I know that this is a budget system compared to what some of you have but as long as it's comparable to the Onkyo TX NR609 it is replacing I'll be happy. Do you know if Dolby Atmos does anything for spatial audio accuracy in a 5.1 setup, especially when the speakers aren't in the perfect position? Maybe this isn't even necessary when Audyssey MutiEQ is already supposed to correct for your room. I'm just curious whether there will be any difference between Dolby TrueHD and Dolby Atmos from a Blu-ray with an Atmos track on a receiver that supports Atmos with only a 5.1 speaker setup. I bought the receiver for 4K/HDR, not Atmos/DTS:X but I'm wondering if I will get any benefit without adding height speakers since the receiver supports those formats.
