Hi Gents,\n\nI'm stuck in a X6400H\/X4400H dilemma. I recently renovated our Games room, and while the ceiling was down, I installed 4 Polk in ceiling speakers (and went from a 6.1 to a 7.1 set-up as well) even though I've never heard an Atmos or DTS-X setup. (I was "future proofing".)\n\nAnyway I finally heard a poorly setup Atmos setup at my local Best Buy store (in Canada) this week. It did sound interesting, but didn't blow my socks off. (It didn't help the Salesman said the Marantz SR7012 9.2 Ch. Receiver that was driving the system was an 11.2, because it had "all the speaker outputs on the back".) There was also a lot of "cross talk" from other sources as this store had the demo in corner of the store, and not in a dedicated room. They also only had 9 speakers connected to it. :( ) \n\nI am contemplating upgrading my existing 7.2 Denon AVR-S900W, so I could connect the Atmos speakers into the system, but the price of the X6400H is scary for the amount of Movies we watch, especially when I can get the X4400H for about half the cost.\n\nI'm wondering if I connected all the speakers to the X4400H, can you easily switch between 5.2.4, 7.2.2, etc without re-running Audyssey each time. I am thinking if we really get into Atmos type movies, I can always add a stereo amplifier later for the last 2 channels. Can you give me any guidance here?\n\nThanks for the assist.
