Sounds like the loading for the MC stage is 47k although that is unusual. It may be worth double checking with Musical Fidelity. The 350uV spec is more typically listed as .35mV which is withing the window of workability for most but not all cartridges. All of my above recommendations fall within that spec. Benz has models in low, medium and high output, all of which would work with that phono stage. Going with a compliancy of less than 15 might begin to be a liability with that arm. The Lyra and Sumikos are a little low with a compliancy of 12, but probabaly still workable. The Denons are lower still.
