Thanks, I found the issue. Indeed I have AVR-X6200W. Had to select 11.1, and 2 channels through a different receiver.
Finally the sound is a lot better. Audyssey DSX still can not really convince me, as the best sound. Dolby Atmos still sounds best with "dolby atmos" selected.
Is there any formula for the height setting?
What do you mean by any formula for the height settings?
Levels should be set correctly by the Denon setup programme. Gibbsy recommends settings the crossover higher than the other main speakers - you can experiment.
DTS-X can sound just as immersive as Dolby Atmos, but it's far less common - there's only relatively few Blu-ray / UHD Blu-ray discs available that have a DTS-X encoded soundtrack, and currently there's no DTS streaming content (this may change with Disney+).
Your Denon AVR should automatically detect and switch to DTS-X mode when appropriate.
For discs that are traditionally encoded (without an immersive Dolby Atmos or DTS-X soundtrack) you have a choice about which up-mixer to use. You can choose between "Dolby Surround" or "DTS Neural:X" mode. I leave my Denon in its default configuration which uses "Dolby Surround" for Dolby encoded material and Neural X for DTS encoded material.
The debate about which is better, rages on...
Not all discs encoded with DTS-X in the US, are encoded with DTS-X when they get a UK / European pressing.
