DC Coupling Capacitor

Friends, which one do you think will give better results?
Siemens (?) 4.7uf
ERO MKT 4.7uf
And I also have MKS Wima 4.7uf 50v.

I asked for advice, if what I have is not available, I can buy your advice. I have nothing to complain about... There are no English stripes on the flag of my country, that's why I speak Turkish. If learning another language is easy, I recommend you to learn Turkish. Our poems are very good.
 
Capacitor C1 AC bağlantı yapiyor. Yani DC blocking. Biraz komik bir kücük hata 🙂 Bence R2 C2'ye parallel olmaye gerekir*. R2 47kOhm olarak.

Which capacitor will sound best is up to you by listening and trying out. ERO MKT1813 simply is very good but I would pick small sized large value film caps in 5 mm pitch and keep connections short and the device compact.

*A tad better is to rearrange like on the picture followed by the 1 kOhm R1 to the LM3886 input pin (and up R2 to 47 kOhm). I would use a 475 kOhm from input to GND too for ground reference.
