you could bypass R2 with a capacitor and have a somewhat similar effect as bypassing a cathode resistor, since it affect the gain ratio dependendt on input frecuency...
i supose thats the idea of bypassing a cathode resistor.
you can use the following formula to find the crossover frecuency (F0)
F0=1/(2pi*R*C)
or
C=1/(2pi*R*F0)
