I find the transients on the BurrBrown has more impact - the smoothness I referred to on the Sabre was the smoothening of that.

FWIW I preferred a friend's DIY-ed AKM4490 to either the UD501 or the Oppo.
Break in? Really, serious. Typically that is hope over poor performance. Its a common affliction of audio people who make bad choices.
I want not to believe in break in, but I've heard it enough that I can't ignore reality.
