Crazy4blues,
I suspect that 60db before your line stage will be plenty for a 501, unless you have a VERY low gain line stage.
I have a Shelter 901, similar output to a 501 (.1mv more). The 67db of gain I have before my line stage is much more than sufficient. I rarely turn the gain control past 9:30 or so, 12:00 would blow the house down.
If you do go with a Shelter or other lowish compliance cartridge, look into whether Twl's HIFI Mod can be fitted to an RB300 somehow. It might take some ingenuity due to the arm's non-symmetrical bearing structure. But it's worth it.
