I just upgraded to a pair of Klipsch height channels with a second amplifier. They're positioned above the L&R up as close to the ceiling as possible (see pic). Ran the Marantz room correction, sat down and plugged in one of the better Atmos Blu Rays and was quite underwhelmed to say the least. The sound quality is fantastic but the overhead effects weren't. FYI, the long haired boss would not permit holes in the popcorn ceiling. \n\nSo I'm wondering can anyone has experienced and can definitively state that DTS-X is truly speaker location agnostic? If not seems I've wasted my money.....:( \n\nMarantz 7703\nMarantz MM7055\nMarantz MM7025\nMarantz UD7006\nParadigm Studio 60 LCR\nParadigm in-wall rears\nParadigm subs\nKlipsch height channels.
