Raul, the SG does conform to the RIAA EQ. But perhaps not as accurately as you think is necessary.
The beauty of the SG setup is that the mechanics of the transducer naturally produces EQ that is nearly the same as the RIAA curve. So the preamp only needs to do minimal EQ. This keeps the phase response intact. I suspect that not requiring heavy RIAA EQ is one of the reasons that the SG sounds good. A little amplitude error is far more favorable than the big phase errors you get from the RIAA EQ.
For the record I do not know if or how much the SG may deviate from the RIAA curve. I do know that it sounds excellent.
To the topic of the thread, I spent a lot of time listening to the Sussorro at RMAF. It is a superb cartridge, that is at home with the best. I have not heard it in a direct apples to apples comparison so I can't comment further.
