My BDA-3 dac and Roon Titan have been on since coming out of their boxes. They were powered off once for ~2 days due to a powerful storm and subsequent power outage. Noticeable difference in SQ upon power up.
As stated above the Directstream is clearing out the cache and resetting/synchronizing clock/buffers etc.
I would keep doing it, but only for the minute you had said above.
