If you have the arm for it the Ortofon SPUs have a warm full bodied sound but they’re low compliance. If there’s a removable headshell than just worry about balancing the 30g weight of the pickup head but if you need 1/2” mounting than the naked N series weigh in at ~16g with the included adaptor so the arm needs to be on the heavy side, 15g is probably enough but a little more might help. I’m getting very good results from a Royal N on an 18g arm, so much so that I’m in no hurry to swap it out for my rebuild Transfiguration Proteus.
The various Hana cartridges keep getting recommended as good value, the low output ones more so.
