The XD equipped cinema sound systems are actually Auro-3D even they might not refer to them as such, that's what they are. I believe Cinemark Cinemas on their XD screens are equipped with Auro-3D.
Oh, okay, I didn't know XD is actually Auro3D. I wonder why they don't mention that.
What's the harm in saying, "XD Auro3D" ?
But anyway, my local Cinemark Tinseltown has XD screens. I definitely love the giant screen size.
But in terms of sound quality, the XD systems don't sound any better than any other good commercial sound systems, including all the ATMOS, SDDS, DTS, THX, etc. commercial systems I've seen, which translates to "they suck compared to my home theater system".
So if this is what you and others have been raving about - Auro3D/XD - then I'm not missing anything.
I wouldn't even pay $20 to upgrade to Auro3D if Yamaha offered a firmware update that could add Auro3D because I don't see any consumer contents. So what's the point. Seriously.
Now if I start to see blu-ray movies with Auro3D at Best Buy, Walmart, or Amazon, that's whole new story. I would want Yamaha to include Auro3D.
I think DTSX sucks right now in terms of contents, but at least they have blu-rays in DTSX, so I still get them.
