I'm not sure how low a compliance cartridge cartidge you can use on your SME4. (Maybe Twl can enlighten here?) If low-medium compliance is game, then the Allaerts (above) or a VdHul Colibri could be contenders. Ultimately, a Clearaudio Insider -- if you live the "hi rez" style of upper level clearaudio cartridges.
OTOH the big Shelter (which I haven't listened to) has been appreciated in many circles. BTW, isn't Shelter made in Japan -- in which case, maybe worth purchasing there.
