with Dolby Atmos in ceiling approach, once you cut holes in the selling, its done. If you don't get it right you're screwed.\n\nAs MANY of us have said REPEATEDLY SO MANY TIMES, you don’t NEED holes in the ceiling and in-ceiling speakers for Atmos.\n\nYou could install your speakers just like Auro3D. Then enjoy all 3 formats - Auro3D, DTSX, and Atmos.\n\nSo there. Install the speakers for Auro3D and enjoy all 3 formats.\n\nAnd I do hope that Auro3D will somehow catch on in the USA. Then Yamaha and all manufacturers will implement Auro3D.\n\nI would also love it if SDDS somehow made it to HT. Then maybe we can have SDDS-Atmo\/DTSX\/Auro3D.\n\nThe more the merrier. Why limit our options?
