Output zobel capacitor types

[zebra100]

From personal experience (subjective though it is), I have never heard any difference when using different types of capacitor in a zobel network. The zobel network on an amplifier output is used to prevent high frequency oscillations causing damage to the output stage of the amplifier. The zobel network should therefor be designed to operate way outside audio frequencies, while still providing protection from HF oscillation. Below its operating frequencies, the zobel will be effectively out of the circuit, and as such will have no sonic influence on the overall sound of an amplifier.

I found that the capacitors are not involved at all in the performance of BIAS, and not easily deteriorate despite possible overheating. My problem with BIAS been satisfactorily resolved with the change of a single transistor. Somewhere I read that the transistors are dealing with that work. (google translation)

English please.

MKT, MKP, X1, X2 types

I had several capacitors salvaged from SMPS. An MKT, MKP and with label x1 or x2 and rated 125vac or dc and up to 1KV. I just wanna know if they will work on zobel caps and also can they be used for power amps . What are the differences of MKP from MKt and x1, x2 caps from y caps. what materials they compose of.. see attached pictures.

I can't believe you guys have spent 3 pages discussing this!!

Stick a 100nF plastic film cap in the zobel. Listen. Stick a 100nF ceramic cap in the zobel. Listen. Which sounds best or do they sound the same as I expect?
There's your answer.

An ounce of experiment is worth a ton of theory.
