Went from a Schiit Gungnir Multibit (R2R chip) to a Lampizator Amber 3 (DS chip + tubes) and it does everything so much better. I was shocked by the improvement having heard only small differences between dacs before. And I used to be a stickler for R2R. Not sure how it measures but it sounds incredible. And yes it did smooth out the top end without taking away detail and clarity (if not adding more).
Point being that you should focus on the sound, functions you require, and synergy with your other gear ... instead of underlying tech (or lack thereof).
