mtbdudex, whoa, and here I feared that adding an 18" sealed jtr sub to my 15" sealed velo may be overkill in my 19x14x8 room...., it's not of course, like you when I got the denon 4520, I went the 11.2 route with dts neo and really like the overall soundfield for tv and movies. I plan on adding 4 in ceiling speakers for atmos, and auro3d with 4 heights and VOG. I want to stay with denon but current planned implementations for both hamstring one or the other, limit use of back surrounds, pirate preout sub2 for VOG, and exclude any use of wides during atmos/auro. I suspect these limited implementations will disappear as next generation of avr/pp become available and dts uhd is rolled out. I think even without movies encoded in either auro/atmos that the upmixer for both( I think atmos avrs/pp may upmix non atmos like auro does) would really add another engaging sound experience over our 11.x currently, and even more so for atmos/auro encoded soundtracks. But I won't be buying speakers, drilling holes in my ceilings, etc until I see that a single avr/pp can do all these without reloading speaker configurations and adding speaker selector switches and crippling other speaker configurations. I will add as many external amps as necessary for it all to work and without limiting each other in the process.
