Tried 1 and 2 - 3 was “over the top” as “2” was for some songs
I don’t want to like the SU-8- but it has its point somehow 
I think the filters mess with the bass response too much for me, so I keep it on standard
I have compared both DACs the first hours in Standard and line out mode
Later on I wanted to try some coloration/spice
I have not trained my analytical hearing since the late 90s early 2000…
The hole process- to be transparent-was more confusing than helpfull
I will have to add the Drop Grace balanced SDAC- anytime to this comparison while it’s available at the moment… I have no motivation for the hassle in the near future… drop orders to germany are so so… a few weeks for delivery… 150$+shipping+19% taxes+28,50€ DHL fee and no free sending back possibilty
from what I read the balanced SDAC is less fatiguing and I had some of those moments with the SU-8 and my DT1990s/660s which I did not experiance with my xDSD in daily usage before
