I realize that trying to compare my analog equipment to my digital equipment is totally unfair.No- it isn’t. Typically LPs have more bandwidth than digital- going up to 35KHz is no problem for most cartridges and the LP mastering machines go up well past that.
I would try a Grado Gold- nice cartridge, works well in a lot of older arms like that.
If this is an idler machine, you can get the idler from Russell Industries on the east coast. http://russellind.com/
