I have been Duelunds for a while especially their newTinned Copper Foil
he best capacitors, but they are Big,
just Jupiter Copper foil are possibly a bit smoother but not as much detail .
Softest, smoothest sounding capacitors you've tried?
Since I'm going for a very vintage sound (my preference), what caps have you tried (speakers or coupling) that struck you as super soft and/or smooth sounding (which would include the effect of being very low distortion). Resolution's irrelevant here. I need large values (2.2uF and 3.3uF), so Russian jobbies are out (already tried them years ago -- they were "OK")
