Capacitor Question /question on cap

[redwine1118]

There are various kind of capacitors for you to choose such as paper in oil, copper foil, MKP, telfon...........all depends on your music preference.

But one of my experience that I found is higher voltage capacitor (over 600V) will be sound better.

I happen to agree... For coupling caps as well.

That's very interesting, since higher voltage caps have more dielectric stuffed between the plates and the plates are bigger to compensate. I'd think that if the bad actors in capacitors are the dielectrics and the metal foils (or metallizations), minimizing them would be better, but apparently not?

U can make an experiment if you want to try :

Copper foil Jensen 0.1uF 630V and 1000V as coupling cap. on your audio gear.

YOU WILL tell the difference


PS : it is not just limit to Jensen....u can try other brand name also.

It does seem rather odd, I know.

For coupling caps I tend to prefer smallish value ( no point in going down to DC) , but at over the top insulation values, prefering a 600VDC cap over a 400 one where a 400 VDC one would have done nicely.

Has it to do with the required strength of the dielectric film? I don't know...

So far it's just something I've had a preference for sonically.

Never really played the same trick on PS caps but maybe Rich has something to add of more value here?

Cheers,
