FWIW re:Soundsmith Strain Gauge cartridge.
As I recall, John Iverson and Sao Win both produced Strain Gauge cartridges (Win also produced a FET-based cartridge) that measured flat as compaired to RIAA curve through their included box, so it is possible.
Why the Soundsmith unit was not made to more closely conform to RIAA (if Peter's description of the SG response and the curves in the referenced article are representative) I am not sure...
