Multistage OA, DC or AC coupled?
Overall you have a gain of 100 so if the DC value on your signal entering to the left of R10 is close to the value of REFH then there might be no advantage keeing C8. However, if the DC value at R10 is say 100 mV away from REFH then the final output will have an offset of 10 volts. Can you live with this offset on the output is what you should ask your self.
