Good capacitors

Hello all, I'm looking for opinions on capacitors for power and audio
filtering. I'd like to replace some electrolytic caps in some old audio
gear, so since I'm tearing it apart I want to put something good in
there. I know caps are notorious for being very cheap, so I want to
know who makes the nice ones. I have a couple different applications:
- power supply filters in a low-power (15W) supply
- audio filter in recording equipment (some of these are ceramics as
well)
- tube amplifier caps (I just threw this one in, I am not too hopeful
about it)
TIA!
