Adding a Pre-AMP to a new configuration

I am currently using my Pioneer PL-670 with a P-mount cart LP Gear with my Pioneer VSX-454

to my Pioneer VSX-1019AHK with now a Pre-AMP but I don't really know what. I have no experience in this area because I just hook to the receiver and since the HT home theater one does not ha the input I have to get a Pre-AMP. I am trying to save space and combine all the functions of both Pioneers in an Audio/Video set up. I was thinking a Schitt but then there is Cambridge but all I know is the budget is $250 or less for a Pre-AMP so nothing really fancy.
