@mdrone as you have a Soundsmith cartridge you may wish to consider a Soundsmith Phono. https://www.sound-smith.com/phono-preamps/soundsmith-mcp2-phono-preamp.
I’m using an MCP2 MKII with my Zephyr MIMC on my Gyrodec w/ SME M2-9-R tonearm and I’m very happy with it. In all honesty I expected this little SS phono to have a temporary place in my rig. It’s still here after 3 years.
That said, I’’d still like to try a Modwright 90x, @elliottbnewcombjr located a great deal on one. I’m tempted to explore it further.
