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 !

Dear @lewm : " Obviously you know nothing about quality resistors ". I think that @mijostyn knows what he was talking about and certainly you don't.
The linked Vishay resistors ( at lower than 1 dollar price. ) were and are a world electronics standard ( not only in audio. ) just as Wima is in the whole industry standard for capacitors. The next link is the 17K+ Reference Phono 3SE by Audio Research and guess what: Vishay Roderstein an Wima:
