The Best Tweak?

You dont get it...

No effect implemented in an incremental way toward a goal , which is perfectly defined by each acoustic aspects of sound can wears off as you want to say...

Why ?

Because when the goal is reached the music coming from any recorded event is so magical , you dont want to stop listening..

 You confuse a change by chance in your system with changes in a wise planned by experiments way...

Maybe not but if you make it a habit the effect where's off.

"but being unable to put my finger on this parameter left me chasing details, micro details, imaging and slam, which can be heartless without PRAT."

WORD

I'm not sure where and why all the other responses came from, but yes cannabis does make the music more "pratty".

By far, addressing the acoustical behavior of your listening room. Bass modes can result in not just constructive and destructive waves creating peaks and/or troughs in bass response, but also "slow" sounding bass due to the resonant modes created by the rooms' dimensions, which left unaddressed linger long after the speaker has stopped reproducing bass notes. And higher-frequency wall reflections can also lead to the smearing of timing cues in recordings. PRaT = timing.
