@sunnyjim i’m not trying to insulting you or anyboby else on this forum (never), but if you leave a comment or advice something, trying to be helpful, please refer to your own experience with certain cartridges, not to the reviwers experience (who’s often got paid for review somehow). Before you will teach me good manners, It will be much more helpful to share your personal experience, don’t you think so? That’s why people ask questions here, including myself.
Apart from the stylus tip, The 103r model has different coil wire compared to 103, i hope you got the answer to your own question.
Nagaoka’s top of the line pm-50 (vintage model) and current pm-500 model are frequently mentioned in Raul’s post here (loads of personal experience), while the pm-150 is just an entry level model and can’t compete with Shelter 501 mk2 MC cartridge.
