I can only tell about burn in period of the whole DS unit incl. Bridge II:
In my experience it had a long burn in period of 2-3 months with nearly daily playing. Improvements were mainly better “flow” and smoother sound eliminating exposed “digital sounding” details and artifacts. Like switching from USB to bridge.
For the DS DAC itself, expect it to continue improving for over 250 hours of playing time, maybe even more. The more significant changes will take place in the first 100 or so, with gradual improvement thereafter. The Bridge takes less, maybe 100 hours with the first 25 being most noticeable.

Thanks :-)
Did you notice other changes in addition to the above mentioned?
