There comes a point in our stereo journey where we have to decide whether it's best to tweak or tune. By that I mean we can embellish upon what we have or we can rethink that which isn't working for us.
Much, I suppose, is dependent on whether or not we're happy with the status quo. If we love what we have built, then perhaps it makes more sense to tweak in the hopes we can get something a skosh better. If, on the other hand, we're struggling with sonic problems, maybe it's better to rethink the setup.
For example, if we have a vinyl-based high-end audio system and, for the most part, records sound great then we're probably best advised to tweak the various arm/cartridge settings to compensate for minor problems. But, if we're not getting the promise vinyl has to offer, then it's time to rethink the system components—to tune by either equipment swapping or a radical rearrangement.
All too often I have run into systems tweaked to within an inch of their life with gadgets, process, bells and whistles, when what was needed instead was a radical tuning or equipment swap.
I think it's part of human nature to want to make smaller course corrections than wipe a slate clean, but it's also human nature to suffer through a situation because we're hesitant to make the big change.
Tweaking, polishing, refining are small changes we can leverage to make what's working better.
Tuning, replacing, rearranging are big changes we often need to make but more often than not shy away from.
To get to where you want to go, do you tweak or tune?
