You have a rabbit hole within a rabbit hole within a rabbit hole here … first there are the issues pertaining to applying EQ in the first place.
Then you can go further and start spending more time considering the strengths of different approaches and specific tools.
And then even within a single tool, especially the more sophisticated ones, there are myriad little controls and settings that effect exactly how your chosen EQ points/values are actually applied/filtered behind the scenes.
Using a non-specifically EQ example, I tend to find that with any DAC that has selectable filters I will often start on a minimum-phase filter and in fairly short order wind up settling on a linear-phase filter as my preference. The longer I listen, the more I find linear-phase to work better - especially in terms of overall listening fatigue, which occurs much more often for me with minimum-phase approaches (though for studio work other factors, principally latency, can trump that).
I’m lucky in that I tend to find things I like, get them setup the way I enjoy them, and after an initial period of fiddling around to get to those points, am happy to leave them alone and enjoy the music.
