value of capacitors in high and low frequency analysis

[faraday]

hi all

I have a Voltage series feedback amplifier circuit with 2 transistors that has 5 Capacitor.
I wanna to analysis that on high and low frequency
Capacitors should be what?

I always use metalized plastic film capacitors for audio coupling because they cause no distortion, are small and are fairly inexpensive.
Ceramic, tantalum and electrolytic capacitors used for coupling signals cause distortion.

thank you for reply
I changed the circuit, removed c5 and put R3=150k, R10=10k, R4=47k
c2,c4=10u ,c3=100u, c1=100n
it works properly
