By the strangest of coincidences I have the same card on a Pi2B....
USB playback is good without interruption or dropouts. I am powering the Hifiberry from the Pi.
You could put some files on a usb stick and try that to see if there is a problem with the usb storage drive.
How are you powering the Hifiberry Digi+ pro ? just the 5v or 5v and 3.3 ?
Ah... just remembered... the jumper by the coax transformer (galvanic isolation) is a fix for earthing loops...see the Hifiberry site for details...
Here is one of many...https://support.hifiberry.com/hc/en-us/community/posts/207749389-HiFiBerry-Digi-Pro-beta-test?page=3
Very short dropouts can be caused by emi from lighting switches etc... again, experiment with the jumper. Also you could try using the Toslink output if your dac has this as input.
