I was just looking for someone's thoughts on watching Atmos files on my DenonAvrx1200. When playing these files it gives the option of either Atmos/Surround or DolbyTHD+ neural:x. The DolbyTHD+Neural:x sounds considerably better than the Atmos setting even with Atmos files. Can anyone explain. To my recollection the Atmos files sounded louder prior to the DTS:X upgrade on the AVR.
