Dear @cfarrow : What other audiophiles can tell you about SUTs are good opinions of the SUT performance is a way different room/system.
My take is to go with the Ortofon ST-80SE, Ortofon is not a " new comer " to SUTs, they manufactured from vuintage one times along its LOMC cartridges as the MC30 or MC2000.
The ST-80SE will mates very good with your Ortofon LOMX cartridge.
You have to care a little on the cartridge low compliance to mate it with the rigth tonearm/headshell combination.
