Matching Rega Aura output setting to PS Audio preamp

It's never easy. Does anyone here have experience with matching a Rega Aura phono stage to a PS Audio Signature preamp? If so, could you tell me what capacitance and load settings you use for the Aura? There are 25 possible combinations and, not being a very technical person, I'd like some advice on where to begin. I do know that adage "trust your ears" but I also know that "a stitch in time saves nine." Thank you everyone! 
I may be wrong, but I think capacitance and loading need to be matched to the cartridge.  The preamp doesn't care what the load/capacitance settings are.  The variables that will impact the interface between the phono stage and preamp are gain, output voltage, input sensitivity, output/input impedance.
