Cartridge incompatibility, Soundsmith and Luxman

I have a Soundsmith Zephyr MIMC Star cartridge that sound really amazing, but I just changed to a Luxman L-590AXII and the gain and loading is fixed.

Output/loading for cartridge: 0.4mV, recommended load resistance 470 ohm

Input sensitivity/impedence for the amp: 0.3mV, 100 ohm

 

The gain should be ok, but the load is way off and you can clearly hear it. The highs are rolled off and I need to crank up the volume to be acceptable level.

 

So here's the question... what cartridge would work in this setup? Would love to keep the Soundsmith, but I'm not going to add SUT with additional cables and all that complexity.

no, i don’t know what is right after the initial loading R. 2 lazy to hunt down a schematic..but the guy with something like 11 patents ..and said inventor of the cartridge in question seemed interested in the schematic… there are after all things, nasty things like tanking circuits… Alas, i am just a retired Economist with a soldering iron and a penchant for surfing the far edge of utility functions of laser trimmed input R, double blind be dammed….

best to all !

Audiogon, the land of “ nearly as good “ but with a penchant for Lagavulin. I prefer Talisker, small sliver of ice….

What is right after that input R ? Some dude who invented the cartridge in question seemed…interested in that…

i am a buyer for the used Hagerman! lines are forming left and right…..

PL was astute in asking for a schematic BEFORE the Scotch…it may matter what comes just after that oh so easy to change input R..

And Mijo, where are you buying laser trimmed Vishay R for $.75 ?
