Those should still be fine cartridges today. I still particularly like the Benz Glider and Wood models (M and L output levels). This hobby & industry is very much driven by a "flavor of the month" and "what’s new" mentality. Small cartridge makers led by ageing artisans seemingly don’t have the time, patience and energy to keep up anymore. For example, Benz and Shelter appear to be winding down, if not already done. Koetsu was finished and is now "back", but how much continuity is there with old Koetsu?
Anyways, "new tech" application to cartridges is sparse. Today we see largely the same old enumerations of materials & designs in endless re-combinations. Hats off to Ortofon, which seem to (still) be actively pushing the tech forward in bodies, dampers, armature alloys, etc. Does all the tech lead to better sound? That varies wildly from person to person (much like the digital vs vinyl debate). Most other companies are akin to garage engineers, where they pick a "gimmick" and then craft their design approach around optimizing that one special thing (e.g. low coil impedance for MSL). The "new" Orgura diamond cantilevers are really nice, but some older carts had diamond too (if not as neatly grown), and it’s hard to say it’s a true leap forward versus a different flavor of sound. The more pedestrian boron rod is still very, very good.
