Thanks for the clarification. That's a huge dealbreaker then. I don't see any reason why DTS/iMax couldn't support a discrete CH if it's in the physical layout and the processing power is there (apart from the fact that only a minority of users could benefit from this, as it requires 12 processing channels. Auro 3D does this fine on the X8500H).

Either they provide the original Atmos (full-range) with objects, or they provide 12 discrete pre-rendered channels with CH if the AVR supports it. I have zero interest in their hybrid 7.1.4 + phantom CH.

Atmos and DTS:X might not have a CH position, but they have FH so you can phantom a perfect CH from that, or position a CH object very accurately there (where it should be, exactly in the middle, above the screen). So arguably a full range Atmos/DTS:X mix using FH to position a CH object would provide better results than their "iMax Enhanced" monstruosity, which is entirely unnecessary from a technical point of view and doesn't bring anything that couldn't be delivered with Atmos or DTS:X.

I'll try one title when I have a chance, but there is no way this will sound good in my setup. Their phantom CH will be in the middle of the screen, not above it, and forward, so basically in my head.

I guess it might work better for those with an AT screen and a C in the middle of the screen, or with C above the screen.

If it does work well, I'll report back, but I'm not holding my breath.

Looks like Trinnov just announced support. Maybe they will be able to render the upper center channel object to the Auro 3D CH speaker.

That's what I would expect on the X8500H as well. With 13ch and CH support for Auro, it seems like a better way to do it than the phantoming.

Yes, if a set-up already includes an Auro Centre Height speaker at or near the top of the screen, then Trinnov can use their proprietary re-mapping feature to stabilize the phantom imaging of the IMAX upper centre. The re-badged version of the Altitude (JBL Synthesis SDP-75) cannot do this because it did not get remapping. As mentioned before, the DTS:X renderer can't do this because the format has no speaker (rendering assumption) at that location (DTS:X Centre Height is around 20 degrees above that location, so the DTS:X decoder will always try to render that object between the Centre Height and Centre, no matter where you place those speakers).

Hello Everyone

I'm buying Denon X-6500 which is IMAX Enhanced? Do I need to buy IMAX Enhanced tv as well to play IMAX Enhanced content or can the IMAX Enhanced AV reciever play its content on my 4K LG OLED659C?

The Denon will play the IMAX Enhanced soundtrack correctly, but to get the full benefit of the IMAX Enhanced program on the picture side you will need a TV set certified to be compliant with IMAX Enhanced. However, that said, if you have a good TV and you are happy with its picture quality, IMAX Enhanced discs should still look great, even if not technically fully compliant with IMAX's intentions.
