Do you like SRPP? It was very popular in the late 90's, then fizzled. I'd recommend doing some research to learn why.
The SRPP setup in this schematic does not offer additional gain, but rather gain reduction. Again, there is gain traded here for lowered output impedance, then there's this extremely high impedance RIAA network (which could be driven by a single 12AX7 gain stage), but then a 15K resistor has been thrown across the whole thing, which will roll off the bass.
