Seems like you have only a MM phono stage. If you have more gain that can handle a MC low output cartridge, but believe that you can't get a good one in your price category, take a look at a Denon DL103R, DL103S, or DL103D. They are all very good low output MC cartridges that are well under your price ceiling. For your "best cartridge under $450" classification, these have to be considered, although they do need about 65-70db gain in the phono stage.
