I have a EMT 75th Anniversary Cartridge (JSD S75).
My system is different and posted on this site. I have a Garrard 301 with Ortofon 309 D tonearm, running the cartridge directly into an Audio Research Reference 3 Phono Preamp.
I have heard the EMT TSD-15 Cartridge. I think the JSD S75 has a little more detail resolution and is more quiet in the groove than the TSD-15.
