Capacitor question

[Apocalypsee]

I'm planning to change some capacitor on my sound card, since all of them are Rubycon YK. What kind of capacitor brand should I look for?

2nd question is regarding type. Polyester, polypropylene, metallized, etc etc etc which one is better to suppress noise and good for music?

Any help would be appreciated

You're going to be limited by size. Most of the aftermarket caps are bigger than what's on your soundcard and you'll have a tough time making them fit on a crammed board.

Most noise picked up by a soundcard comes from RF noise thrown off by your power supply, fans, and other components. The inside of a computer is loaded with electrical noise. Replacing capacitors will do nothing to change that.

Generally, it is better to use an external soundcard, or just run a digital cable out of it to a DAC. Otherwise, you'll spend a lot of money and time on something that won't make a difference.
