I still have to do some precise comparison, but sound wise I believe, for now, that DT sounds better than OT, being mk1 or 2.
Overdrive, filter, reverb are in my very humble opinion (neither expert nor fact-checked yet) “cleaner” on DT.
This is a real point to me, as I love OT workflow : live sampling, crossfader + scenes, plockable FX are all key points to me.
But DT sound is extremely good, to the point that I want to take the time to compare it with OT with the exact same samples. I have to find what I do in OT that would taint the sound.
I do believe that the pb hides in the way I handle gain staging.
