agram4,
When you say that the difference became readily apparent after 200 hours, are you saying that the Eversolo T8 and Denafrips Pontus 15 combination was better than your Rose 520B? If so, in what way?

I hear you. I play 600 hours of pink noise through any new component I purchase before I do any critical listening. Even cables. For DH Labs cables I increase to 800 hours because of their stiffness.
I’m going to increase the pink noise to 52,560,000 minutes and then I’m going to my grave 
.

R2R DACs (the Denafrips) sound more analogue like… so there’s that.But to answer your question: 1) bigger soundstage, especially depth and 2) timbre/tonality music sounds more "natural’ or maybe to say less digital and, 3) rhythm and pace picked up a tick. Not that the Rose is bad, it’s just that this combo is more pleasing to my tastes…I don’t get “ear fatigue” with this combo (can listen longer)…Hope that helps
Enjoy the music
agram4,
Yes, it helps a lot. I had an R2R Dac previously- a LAiV Harmony (the full size one) and I understand where you’re coming from.
