Precision Fidelity C7/A Revised: Denon DL103R

I am using a Pickering cartridge with 5mV output and a PF C7A preamplifier. The cartridge has very high gain through this preamplifer, so I am wondering if the Precision Fidelity can handle the lower output 0.25mV output of the Denon 103R without using a step-up. Right now the sound is quite loud even at a quarter of the volume setting on the preamp. Thanks for your help.
