Thanks for the feedback guys.
Why would some of the default settings need to be changed? I thought if bit streaming the DD from the PS4 and using the DD mode on the X7 I wouldn't even use the SBX option on the unit. Or do any tweaks you make in the control panel also effect the DD mode as well?
All of the tweaks affect the DD signal. By default SBX is turned on, alongside Crystalizer and Bass Boost (separate tweak from the EQ). Crystalizer and Bass Boost should be turned off and only turned on after getting acquainted with the X7 as they affect the sound in a very artificial way.
