High jitter (from aggresive DSP ???)

[Snoopy8]

I cannot find the night mode option in the app.
Do you guys know if reactors have this option?
Can you please guide me to it?

It indeed sounds like a volume leveler is applied.

As I mentioned earlier, I am unable to use the Devialet App because it is not yet ready for my Phantom Gold.  In the Spark App which I am using, it is a moon symbol on right side of the volume display but I cannot see an equivalent screenshot for the Devialet App.

Suggest you contact Devialet support who are usually responsive and helpful.
