Holographic experience is also very much connected to the state the mind is in. A pessimistic mind is locked, optimistic mind can be a fantasy/placebo. The best experience when the mind is disconnected from rational thought, any thought. Just music. No numbers and measures.
It sounds like a joke, but it is "dangerous" mindset to only listen to the changes and tweak. It will be less music joy, and more of a sport.
Therefor I see it is as very important to have a goal with what is being done as tweaks.
You seem to be dedicated to have the black background. I assume what you are saying here:
You are not looking for an "airy sound" in the top notes right?
What I think you should aim for is a darker sound/texture(DAC), not veiled. This will also make the music less distracting because of all the information an details in the high frequencies are not dominating. However, If you "feel like it", you can still hear them but they are not the important factor.
If you want to feel the background like in this scene(from Stranger things 5)
Don´t aim for a brighter sounding DAC.
