I believe the answer to this question is temporal. Digital technology seems to be changing monthly (my impression...not based on empirical evidence). When it comes to those who modify machines, the quality of their end product can change faster than one might imagine, because they are constantly tweaking to refine their mods. One has to make a decision and act upon it, because the longer the decision is postponed, the longer one will be without SOTA digital playback.
It seems to me no matter what digital playback one chooses, one can be certain that something better will come along just as soon the new player is broken in!
