Ed,
Your approach certainly makes sense too, and either approach could be done for less than the cost of the Mu's. Lots of ways to skin this cat, or pull this cart if you prefer.
Sidssp,
A 1:10 stepup shows a cartridge a load of 470 ohms, not 235, assuming normal MM phono stage resistance of 47K. I think you mis-read BentAudio's chart. Regardless, your question still remains valid: will this be appropriate for a Statement Sonata?
The load needed by a cartridge if feeding a transformer is quite different than if feeding a gain stage. The goal now is not to maximize voltage output but to maximize current output without over-impeding the cartridge. This requires a much lower load. For MC cartridges feeding a tranny s typical "ideal" load is about 3x the internal resistance of the cartridge. The Statement Sonata is listed as having a very low resistance, just 2 ohms. If it were an MC you'd start by loading it down to about 6 ohms and experiment by ear from there.
Whether this applies to a MI or MM Grado I don't know, and Grado doesn't specify a load for the cartridge if using a tranny. One should probably ask Grado before deciding to go the tranny route. Good point.
