I own the STI-500 and the DAC2 and it did take quite a long time for the STI-500 to sound its best. But if you're missing detail, that could be something different. Presenting fine detail is one of the many strengths of the STI-500 so maybe it doesn't like the same cables (especially power cord) that the Bada gear liked.
The speaker cables and the power cord seem to work as a team, so consider that. And the interconnects play a part as well. Are you using a good quality AC line conditioner? If not, you should be.
Also, I'd change from the variable output to the fixed output on the DAC2 if you haven't already done so.
You might also move the roll-off setting of the digital filter one notch up (to 50k, I believe) as that will extend the highs and apparent detail a bit.
It's hard for me to imagine that the Bada gear could give as much detail as the STI-500, let alone more. But combinations of different gear and cables are virtually unlimited, so anything is possible, I suppose.
