Hi Quanghao, today i have bought 0.1uF Wima capacitors for power supply of IV stage C1 to C4.( in the picture below). Do you know, can this capacitor withstand the voltage?
Thanks

Wima capaciotrs are not the top but enough good if you use MKP but please don't use MKS.

I consider very good the Auricap but these are very expensive.

My first choice for any interstage use is the Jensen Copper film in paper oil.

In my Pre Phono 4 I have used the Wima MKP but someone got better result with Solen and SCR.

I agree with audiodesign about Wima caps. They sound thin, dry, sharp. Don't use MKS.

If you really want to use the one in the picture you can the voltage is enough.

Quanghao the 250V~ is AC that means they can handle 400V DC easy.
