Matching a DAC to Preamp considerations?


Are their any considerations in regards to matching a DAC to a preamp?  I'm looking at the Denafrips Terminator which as the listed output impedance: 

RCA at 2.3Vrms, 625 Ω
XLR at 4.6Vrms, 1250 Ω


Is there any concern with match these measurements with a Bryston BP26 preamp that has in input impedance of 15k ohms balanced or 50k ohms single ended?  

Greatly appreciate any input/guidance.

Best,
Mike
