I sense a bit of the cynic and the pragmatic here.
Yes, getting lost in the weeds and constantly trying to upgrade can be an end to itself, one of the defining characteristics of addiction. That is not the case here, as I see it.
Not of deep pockets, my refining is of a more subtle nature: a tweak here, a minor purchase there, and never at a constant pace. I can go well over a year before tinkering. If I had large enough disposable income, I'd have several systems and be content that I've covered most of the bases.
Just now, it occurred to me that even with a few different set ups, it's still the same path, as you now have several options to attainment, depending on your mood. I envy that.
All the best,
