Low volume on turntable??

Hi everyone, so I’m new to vinyl and have a lot to learn but I just hooked up a my first turn table, and with my preamp at maximum volume, and amp at full gain, it was still veryy quiet and had no depth/bass. The turntable is an old Denon DP-31L that I just installed a new cartridge in (AT-95E) --->Cary Audio AES SE-3 preamp---->McIntosh MC2125--->Klipsch RP-5’s. The system sounds magnificent running .wav vinyl rips with a Monarchy DIP upsampler--> Emotiva XDA-1 DAC in between my comp and the preamp, so there must be something wrong with either the unit, or how i hooked it up (basic built in RCA to preamp, with the integrated ground wire running to the Mcintosh chassis). On the plus side the ultra-quiet music has no hums, or background distortion whatsoever, even at full volume.

Any advice or thoughts would be much appreciated! Cheers
